Allergy after fever. Fever as one of the symptoms of allergy: fever treatment and possible complications

• Types of allergic reactions in which the temperature may rise
• How to distinguish the temperature with allergies from the temperature with other diseases

What happens in the body with allergies

In most cases, allergic reactions occur against the background of a previous encounter with the same allergen, and both local and general reactions may occur. Local reactions- This different kinds rashes inflammatory reactions mucous membranes respiratory tract, conjunctiva of the eyes, sometimes - joints.

But, in addition to local, there are also general reactions due to the formation in the blood a large number immune complexes consisting of an allergen and a class E antibody associated with it. The more such immune complexes, the stronger this reaction, the higher the likelihood of symptoms atypical for allergies.

So, is there a temperature with allergies? Yes, heat with allergies can be the result of intense general reaction to an allergen, accompanied by the release of a large amount of histamine and other biologically active substances.

What types of allergies are most commonly associated with fever?

According to medical observations, temperature most often occurs with the following types of allergic reactions.

1. drug allergy - hypersensitivity to diverse medicines, manifested by high, up to 39 degrees or more, temperature and other symptoms: skin rash, itching, signs of general self-poisoning of the body.
2. Serum allergy is an allergy to vaccines and therapeutic sera, which can manifest itself not only with fever, but also with other severe symptoms.
3. Allergy to bites of poisonous hymenoptera insects (bees, wasps, hornets, etc.).

Less often, the temperature with allergies occurs when hypersensitivity to allergenic foods, to pollen and dust, to pet hair.

From what to distinguish the temperature with allergies

Often, the temperature with allergies in a child is not a symptom of the allergy itself, but of a concomitant infectious-allergic process - acute or chronic. Even if there are no manifestations of infection at the time of the temperature, this may indicate that the child's body is in the prodromal period - the period preceding the disease.

Therefore, when a temperature appears in a child with allergies, one should not make hasty conclusions. It is required to carefully examine the baby and exclude all other causes of temperature. If other diseases are found, then it is necessary to prescribe appropriate treatment.

When can one think that a rise in temperature in a child or an adult is due to an allergy?

1. If there accurate information that the patient has come into contact with a substance to which he had previously shown hypersensitivity.
2. If the appearance of temperature coincides with or is associated in time with the patient's contact with the allergen.
3. If, in addition to fever, there are other symptoms of an allergic response to a substance: skin rash, Quincke's edema, signs of anaphylaxis, etc. Moreover, the more pronounced other signs of allergy, the higher the likelihood that the temperature is due precisely to an allergic reaction.

It is important to remember that temperature cannot be the only manifestation of an allergic reaction, so it is important to evaluate all the complaints and symptoms that bother the patient as a whole.

Temperature treatment for allergies

A low temperature, up to 37.5-38.0 degrees, does not require taking medications that reduce it. The patient is given the usual treatment: antihistamines, limiting the intake of the allergen, cleansing the body.

Higher and rapidly rising temperature, especially after contact with some kind of allergen, drug or hymenoptera venom requires immediate medical attention. In these cases, an increase in temperature may indicate life threatening an allergic reaction that can develop into such severe manifestations as angioedema (Quincke's edema) or anaphylactic shock.

Is it possible to increase the temperature with allergies

An allergic reaction, as you know, is a specific work of the immune system that occurs in response to the introduction of a foreign protein.

As a result of such a reaction, certain complexes are formed in the body, which lead to the development of all kinds of manifestations of allergies.

Such a sign as temperature with allergies is enough a rare thing, but it is quite possible in certain situations.

If the temperature rises with allergies, then this most often indicates an atypical reaction. immune system to the allergen that enters the body.

The jump in temperature is explained with an allergic disease not by a reaction to an allergen, but by the changes that occur during this.

That is, a pronounced inflammatory reaction on the skin, disturbances in the work internal organs can cause febrile syndrome.

Usually, the temperature with allergies rises slightly, that is, up to 37 degrees and much less often up to 38.

In the process of monitoring their patients, allergists have identified a number of allergens, in which the temperature reaction of the body most often develops.

belong to this group.

drug allergy.

Certain groups of medications may cause skin rash, itching on the skin, nausea, symptoms of suffocation and fever are also not uncommon.

Serum intolerance.

Temperature with allergies in many cases occurs with serum sickness, that is, with intolerance to certain proteins that make up sera and vaccines.

In this case, the febrile syndrome can be very pronounced.

Bites of various insects.

Often people in the warm seasons of the year suffer from allergies to insect bites: mosquitoes, bees, small gnats.

With such injuries, due to the introduction of biological fluids toxic to humans, an inflammatory reaction on the skin is strongly pronounced, swelling, hyperemia, itching develop, and temperature is a consequence of all these ongoing changes.

At the same time, it can be not only local, but also general, which is especially typical for young children.

Much less often, the temperature during allergies occurs on foods intolerable to the body, household dust, grass and tree pollen during flowering, animal protein.

The temperature reaction of the body against the background of an allergy can be provoked not only by contact with the allergen, but also by other provoking factors.

To eliminate the manifestations of the disease and improve well-being, it is necessary to choose the right treatment for everything, so it is always important to find out what caused the febrile syndrome.

How to tell if a fever is caused by an allergy

Temperature with allergies manifests itself in almost the same way as fever with viral and other inflammatory diseases.

But the treatment in these cases will be different and the use of an incorrectly selected therapy regimen can adversely affect well-being.

Therefore, it is always important to accurately determine the cause of the temperature jump.

The fact that the temperature during allergies is caused precisely by the introduction and action of the allergen in the body can be independently assumed by the fixation of other signs of an intolerance reaction.

They include:

• Allergen contact. If a person knows that he has allergic reaction to a certain irritant, then it usually excludes contact with this allergen. And certain signs of deterioration in well-being indicate that the irritant has entered the skin, mucous membranes or the gastrointestinal tract.
• Allergy is also manifested by skin itching, sneezing, expiration of an abundant and transparent secret from the nasal passages.
• Temperature with allergies may be accompanied by itching of the conjunctiva of the eyes, lacrimation, rashes on the body.

With viral and bacterial infections respiratory signs can also be expressed by sore throat, symptoms of intoxication, lethargy, weakness.

An allergy attack upon contact with an irritant usually develops in a few minutes.

Cold manifestations of infection increase gradually and are characterized by certain stages of inflammation.

A high and rapidly rising temperature with allergies indicates a violent reaction of the body to the allergen.

With such intolerance, anaphylactic shock and Quincke's edema very often occur.

Therefore, if you notice increasing shortness of breath, suffocation, increasing swelling of the face, eye area, then you need to call as soon as possible ambulance or ask your doctor for help.

Causes

Temperature with allergies in adults and children can be triggered by the factors shown in the table:

Factors	Associated symptoms
food allergens	It is possible that at food allergies body temperature can rise to 39 degrees. Acute manifestation food intolerance can provoke increased sweating, skin irritation, rash, fever.
Medications	It proceeds with irritation of the mucous membranes, itching, signs of intoxication and fever up to 39 degrees.
Vaccination	A routine vaccination can cause a rash, swelling and hyperemia at the injection site, as well as a fever of 38 degrees and above. This condition is a medical emergency.
Animal fur	The temperature for allergies in a child and an adult in this situation varies around 37 degrees. Taking antiallergic drugs eliminates the signs of allergies, including subfebrile temperature.
Pollen, ambrosia	If a person suffers from intolerance to pollination and flowering of plants, sometimes his temperature may rise against the background of other manifestations of allergies: rhinorrhea, conjunctivitis, etc.
Insect bites	The temperature usually rises exactly at the site of the bite, which at the same time hurts and swells.

How to determine that the cause of the temperature increase was an allergy?

The temperature with allergies in children and adults is practically no different from a febrile state with colds. But the treatment of these conditions cannot be the same, moreover, if it is wrong, it will certainly affect the person's well-being. So true reason temperature rise must be determined accurately.

Disease	Characteristic features
Allergy	If a we are talking really about an allergic condition, then, in addition to the fact that allergies can cause fever, there are other concomitant symptoms given state. Interaction with the allergen ends clinical picture known to every allergy sufferer: pruritus, sneezing, red rashes on the skin, allergic rhinitis and much more.
SARS and FLU	With infections of the respiratory tract of viral or bacterial origin, the temperature is always accompanied by a sore throat, signs of intoxication of the body, headache, that is, symptoms that have nothing to do with allergies.

It should be noted that an allergic reaction is formed quite quickly - its signs can appear already a couple of minutes after contact with the allergen. In turn, a cold begins gradually, it is characterized by a staged development, and, on average, lasts at least 7 days.

Features of temperature for allergies in children

The immune system of a child is not as perfect as that of an adult. Therefore, it is much more difficult for her to be able to resist external pathogenic factors, in particular, allergic irritants. For this reason, allergic reactions occur more often and more acutely.

An allergy with a temperature is more dangerous for a child, as it can lead to serious complications. Therefore, if you suddenly develop a fever after a vaccination, insect bite, or medication, you should not hesitate to seek medical help.

What should be the first aid?

Whether an allergy can give a temperature is an extraordinary question only until the moment when the allergic person himself encounters this condition. If appropriate measures are not taken, the temperature may continue to rise, which will adversely affect well-being. To correct the situation, you should use the following tips to reduce the heat.

1. Eliminate or minimize contact with an irritating factor.
2. Take an antihistamine that was previously prescribed by your doctor. If not done before drug treatment, you can take Suprastin, Zyrtec or Loratadine at the dosage recommended for age. Most often the impact antihistamine completely eliminates not only clinical manifestations pathology, but also the temperature that accompanies it.
3. If an insect bite was recorded and an allergic reaction developed almost immediately, it is necessary to rinse the bite site with plenty of running water as soon as possible and treat it with any anti-allergic ointment. This will help relieve the local inflammatory process.

1. To improve overall well-being, you can take enterosorbents ( Activated carbon, Enterosgel, etc.), which help to eliminate toxins from the body. Also, for this purpose, it is advisable to drink clean non-carbonated water in sufficient quantities.
2. If there is a suspicion that the allergy is caused by a drug, it is necessary to stop using it for at least the next period of time. It is recommended to contact your doctor who will select an analogue this drug and exclude additional causes that can cause an increase in temperature in the future.

Treatment

The answer to the question - can there be a temperature with allergies and what should be the treatment, all allergy sufferers should know. If an adult or a child has a fever and all the signs of an allergy are present, first of all, you need to contact a specialist. The main thing is to consult with him in a timely manner, since a further increase in temperature values ​​\u200b\u200bis not excluded, and then complications cannot be avoided.

If the temperature remains within subfebrile condition or slightly exceeds 37 degrees, there is no need to take an antipyretic drug. If its values ​​\u200b\u200bexceeded the mark of 38 degrees and continue to grow, you can give a drug to relieve heat before the doctor arrives. It can be Paracetamol, Nurofen, etc.

To combat the allergy itself, experts prescribe antihistamines. Their action is to inhibit biologically active substance, which provokes the symptoms of pathology. Medications from allergies are presented in three generations. This case requires the use of first generation drugs, as they are stronger and give a quick effect. Their list includes Fenkarol, Suprastin and others.

If a skin onset of rash, preferred for rash in adults hormonal ointments(for example, Hydrocortisone, etc.). AT childhood it is desirable to use non-hormonal agents, for example, Panthenol, Bepanten, etc.

What happens in the body with allergies

Allergic reactions can occur immediately after the body encounters the allergen or appear after a certain time, when an excess of allergenic substances occurs. In any case, both local and general allergic reactions are manifested.

Local symptoms include:

• Rashes of various localization;
• Inflammatory processes of the mucous membranes of the mouth, nose, eyes;
• Inflammatory reactions of the joints.

General symptoms:

• The formation of a large amount of histamine in the blood;
• Increase in the limit of the norm of immunoglobulin class E;
• The appearance of symptoms atypical for allergies.

So, is there a temperature with allergies? The answer will be unequivocal. Yes, with allergies there is a temperature, such a process is due to the fact that the body is oversaturated with allergenic substances. As a result, an intense reaction of the immune system and the release of a large amount of histamine. In addition to the antigen, other active substances are also released.

Allergy sufferers are also interested in: “Is there a temperature with allergies?”. Yes, it happens, and what is the reason for its appearance will be discussed further.

Very often, when a person develops an allergy, the signs and symptoms of the disease at the initial stage of its development are confused with a common infection or cold. But allergens cannot cause inflammatory pathologies, this must be known and remembered.

Why is there a temperature in allergic reactions in children?

Temperature with allergies in a child can be caused by:

• food allergies;
• Intolerance to a certain number of drugs;
• Allergy to dust, pollen, etc.;
• Conducting vaccinations;
• Allergy to hymenoptera and other insect bites.

If, in addition to allergic manifestations and fever, the child has other symptoms, these may be symptoms of another disease.

Temperature with allergies in adults, as in children, is provoked by almost identical allergic processes:

• food allergy. Manifestations: rashes, redness of the affected areas of the skin, drops blood pressure, acute pain in the abdomen, high fever and much more;
• Allergy to drugs. Manifestations: severe itching and peeling of the skin, swelling of the mucous membranes and their inflammation, a sharp increase in temperature ...;
• Allergy to protein. Manifestations: Symptoms can manifest themselves in different ways. With a severe course of the disease, anaphylaxis develops;
• Allergy to wool, pollen. Manifestations: inflammation of the mucous membranes, annoying cough, a slight increase in body temperature.
• Allergy to insect bites. Manifestations: swelling and redness of the affected areas, local or general fever.

Often, at a doctor's appointment, patients are also interested in the following question: “Does the temperature rise with allergies regularly or does it depend on the type of disease?”. As noted above, this process is individual and does not depend on the type of allergic reactions. Most likely, this is an exception to the rules that cause an ambiguous reaction among doctors, but, unfortunately, such a phenomenon occurs.

It is also very difficult to unequivocally answer the question of what temperature with allergies can be. The limit of her jumps is not limited.

Most high rate observed in people with a predisposition to protein and in childhood after vaccinations carried out according to an individual schedule.

Facts of raising the temperature with allergies

To refute or make sure that it was allergies that caused the increase in body temperature, we recommend that you find out the following:

1. In rare cases, the temperature can be caused by contact with an allergen to which an allergic reaction has previously manifested.
2. If the temperature appears immediately after the ingestion of the allergenic substance or direct contact with it.
3. If, in addition to temperature, the disease proceeds with a rash on the skin, Quincke's edema, signs of anaphylaxis and other allergic symptoms.

Causes of a rise in temperature with allergies

The above is true for the "norm", in general case. But then why does the temperature rise with allergies? If the reaction "grows", expands, acquires a systemic character. The organism loses the remnants of control over the situation, a “global” process develops.

There are other special situations that cause a non-standard course of the disease, for example:

• drug allergy;
• allergy to insect bites;
• photodermatosis;
• serum sickness;
• less often - food allergies.

Thus, the answer to the question of whether an allergy can give a temperature is positive.

Temperature increase in various allergic diseases

Consider some allergic diseases in details.

For the nasal mucosa, histamine is the “worst enemy”. It causes swelling, local redness, the appearance of sparse mucous secretions in large quantities, itching.

In the case when lacrimation, a feeling of sand in the eyes and other phenomena join the runny nose allergic conjunctivitis temperature increase is more likely.

Most often, rhinitis develops with seasonal exacerbations, for example, hay fever - allergies to pollen. However, the type or “period of activity” of the allergen cannot be associated with the risk of fever, they are not related to each other.

Therefore, it does not matter in what season of the year an allergic pathology developed - whether in spring, at the time of flowering of plants, in autumn, when dust mites and mold fungi feel great, or in winter, during the "reign" of cold allergies. And it is impossible to say that hyperthermia develops more often in summer or, for example, in autumn.

Allergic cough and bronchitis

First, it is worth differentiating these concepts. By allergic cough, we will mean reflex attempts to clear the larynx during tickling, “tickling”, hoarseness. But bronchitis is a deeper process that affects the actual bronchi.

In the first case, an allergy develops extremely rarely, there are literally a few such cases. Perspiration and the cough it causes are inherently close to allergic rhinitis and develop as a result of mucosal edema.

But allergic bronchitis with temperature is a slightly more frequent phenomenon. Despite the fact that the presence of hyperthermia accompanying a dry barking cough is a sign of a process of a bacterial or viral nature, there are exceptions.

In favor allergic bronchitis with hyperthermia, shortness of breath and a productive cough will testify from the first day of illness (returning to the effects of histamine - constriction of the bronchi and increased secretion of mucus). It is worth adding that, among other things, this mediator dilates the vessels of the lungs, increases their permeability, which leads to even more severe edema and narrowing of the bronchi. And, of course, required condition- the presence of contact with the allergen.

This disease is a good illustration of the question of whether there can be subfebrile temperature with allergies. Usually, 38° is the limit, if it reaches it at all. By the way, this is another distinguishing feature: with bacterial or viral bronchitis, the thermometer can “crawl” up to 39.5 ° C.

food allergy

Food allergens are among the least aggressive. In this regard, the development of temperature changes in food allergies is unlikely. However, it is possible. Hyperthermia will develop when there is a very strong reaction with the presence of:

• indomitable repeated vomiting;
• profuse diarrhea;
• intense pain in the abdomen;
• headaches, dizziness.

Usually the mercury column does not rise to high numbers. The maximum is 37.5°.

Allergic dermatitis

Photo: Allergic reaction to cosmetics

Allergic dermatitis and temperature are rarely combined. For the development of such a complication, the surface of the lesion must be very extensive.

Most often, a “cosmetic” allergy has such serious consequences, in the case when a person did not conduct a preliminary test, but immediately applied the remedy to large plot skin. The risk is especially high when combined sunburn allergic to sunscreen or emollients.

Often the thermometer shows from 37 ° to 38 °, when skin manifestations are combined with some other - respiratory, ophthalmological, etc. High temperature is an even greater “curiosity”. If dermatitis is accompanied by it, you should immediately call a doctor, as a severe generalized reaction may develop.

Photodermatosis

Allergy to the sun itself is difficult to distinguish from a sunburn. But if one is superimposed on the other, or overheating and sunstroke join, life becomes very difficult. Both of these pathologies carry unpleasant symptoms, but when they are combined, the human condition worsens significantly. Painting sunstroke is:

• high body temperature, sometimes patients complain that the temperature jumps, then up to 39 °, then down to 35 °;
• dizziness;
• nausea, vomiting;
• weakness;
• loss of consciousness;
• disorientation;

But the symptoms of sun allergy are different:

• red blister-like rash on exposed skin;
• itching, peeling of the skin;
• local redness.

Allergy to insect stings

Bites and stings, to which the body reacts with an excessive immune response, are often accompanied by fever. But it must be said that, as in the previous paragraph, here the temperature accompanies not so much the immune processes themselves, but their combination with the main factor (in this case, the effect of insect venom on the body).

In addition, the immune system, as it were, is “busy” with allergies and literally does not have time to respond to the poison.

Photo: Allergy to a mosquito bite

The temperature in this case can rise to 38 °, there is a deterioration in the general condition, weakness, often headache. All this is combined with local symptoms:

• hyperemia (redness) of the bite site is much more intense than in the absence of an allergic reaction;
• intense itching;
• the appearance of a rash around the bite;
• the occurrence of allergy symptoms from other organs and systems.

drug allergy

Allergy is like hives with fever, and rash, and swelling - in its “pure form” a reaction to drugs. The temperature in this case rises to 38-39 °.

Generally speaking, drug allergy is one of the most dangerous and severe diseases of an allergic nature. Drugs are introduced into the body in fairly large (compared to the same dust or pollen) doses.

The logical question is why then there are no severe symptoms with gastrointestinal allergies? But not all substances are not completely absorbed in the intestines, they are partially excreted. In addition, the allergen needs to overcome many more barriers to get into the blood.

life-threatening development of events in drug allergy is anaphylactic shock. Therefore, an increase in temperature can even be called a rather favorable symptom.

Photo: Allergy to drugs

In addition to it, there may be:

• itching, rash at the injection site;
• weakness, dizziness;
• sneezing, rhinorrhea, lacrimation;
• soft tissue swelling.

But this pathology confidently answers “yes” to the question of whether there can be a temperature with allergies, because. hyperthermia is one of its main symptoms.

Before describing the disease, it is worth saying that there are 4 types of allergic reactions. Three of them are immediate and one, the fourth, is delayed. What we used to understand as an allergy (including “popular” symptoms and anaphylaxis) is type 1. Type 2 (which, by the way, includes drug allergies) are cytotoxic reactions that damage cells. The fourth type is delayed reactions, such as tuberculosis and bronchial asthma.

Symptoms for all reactions of this type are the same: a week and a half after the allergen enters, first a sharp hypothermia is detected, and then, on the contrary, hyperthermia.

Other symptoms include:

Photo: Urticaria as one of the manifestations of serum sickness

• pain, swelling and redness at the injection site;
• enlargement and soreness of nearby lymph nodes;
• the appearance of a rash on the body, accompanied by intense itching;
• pain, swelling of the joints;
• sometimes laryngeal edema develops;
• the heart muscle is affected;
• suffering nervous system(possible neuritis, sciatica)
• etc.

The only good news is that in most cases, after a few days, all manifestations pass by themselves.

Temperature and allergies in people at risk

Let us consider in more detail the features of the course of allergic reactions with temperature in people from risk groups.

Temperature for allergies in the elderly

Allergy in the elderly, like any other disease, occurs with a much less intense severity of symptoms. To illustrate this thesis, it is worth saying that people over 65-70 do not experience significant pain even with appendicitis.

So with allergic reactions - the symptoms are smoothed out, the diagnosis is difficult, there are practically no subjective sensations. In order for an elderly person to have a fever with allergies, a “giant” reaction is needed, expressed extremely intensely. Such a problem can develop with the introduction of the drug and in the case of serum sickness. The temperature will rise to 37-38°.

Temperature for allergies in pregnant women

However, it should be noted that hyperthermia develops in expecting a child much less frequently than in ordinary women. This is due to the fact that immunity during pregnancy noticeably weakens, allergic reactions are frequent, but they are mostly minor.

The most common of these is allergic rhinitis of pregnancy. Diseases do not tend to generalize the process.

Temperature for allergies in children

The body of a child is much more sensitive to various stimuli than an adult. Therefore, in children, allergies are more likely to cause a rise in temperature.

Dr. E.O. Komarovsky believes that the most important thing is to understand whether allergies are the “culprit”. For example, when figuring out whether an allergic cough bothers a child or an infectious one, it is worth taking as a basis the fact that there should be no temperature reactions with hypersensitivity.

But if the temperature stays up to 38 ° for no particular reason, this may be an allergy. However, after 2-3 days, other manifestations must necessarily join it ( allergic rhinitis, conjunctivitis, skin symptoms etc). Children are more likely to have a heightened immune response with fever to vaccinations and medications.

Another option is the appearance of only temperature as the main manifestation of an allergic reaction. This option can only be considered in children. This indicates a low activity of the immune system and, paradoxically, a very serious allergic reaction.

It is possible to understand that we are talking about an allergy symptom only by “anamnesis data” - whether there was contact with an allergen or, perhaps, the child is in the prodromal (preparatory, preclinical, asymptomatic) period infectious disease. In this case, it is urgent to show the baby to the pediatrician.

However, you still need to focus on the fact that with allergies, children should not have a temperature.

Differential Diagnosis

This section is extremely important. Temperature, even a slight one, is a rather dangerous symptom. Keeping it for no apparent reason may indicate serious and dangerous diseases(tuberculosis, heart disease, oncology).

As for the temperature during allergies, this phenomenon is non-standard. And that is why it is so important to make sure that hyperthermia is precisely of an allergic nature.

First of all, of course, you need to focus on the accompanying symptoms and build on them.

Briefly, we can say the following:

• With acute respiratory infections, a runny nose is characterized by a viscous, greenish discharge, a tendency to nasal congestion without rhinorrhea. With allergies, on the contrary, the mucus is liquid, transparent, easily and abundantly excreted;
• ARI is characterized by headaches, heaviness in the head, weakness, a desire to close your eyes, hide warmly and sleep. In the clinical picture of allergy, the main symptom is itching.

When gastrointestinal symptoms are observed, it is incredibly important to distinguish an allergy from a poisoning or an acute intestinal infection!

During the infectious process, the temperature rises to much higher numbers (39 ° or more), there are:

• blanching of the skin,
• weakness,
• dizziness.
• In severe cases, even loss of consciousness.
• Always is profuse vomiting, constant nausea, there is a danger of dehydration.

It is vital to distinguish photodermatosis from severe course from heat stroke.

Treatment and prevention of fever

It is worth saying that if the temperature does not rise above 38 ° and does not cause much concern to the patient, it is not necessary to bring it down - it will pass on its own.

The boundaries between medication and folk treatment in this situation are somewhat blurred. The fact is that the first recommendation that any doctor will give is plentiful drink. You can drink:

• water;
• decoctions of herbs (for example, chamomile) - be careful! May cause re-allergy, intensifying symptoms!;
• rosehip decoction;
• fruit drink;
• compote.

It is permissible to add lemon, honey (in the absence of allergies to them), mint to drinks.

If the temperature does not drop, apply:

• antipyretics (Paracetamol, for children - Nurofen);
• antihistamines (Claritin, Zyrtec, Suprastin, etc.);
• with food allergies - enterosorbents (Smecta, Polysorb).

Don't rush to use hormonal preparations even with local allergies. There is a possibility of an error in the diagnosis, and then with the use of glucocorticoids, the risk of spreading the infection increases significantly.

It is better not to engage in self-treatment of children. If within a few hours on their own, with plenty of drinking and taking 1 dose of Nurofen and an antihistamine, the temperature does not subside, seek medical help.

Prevention of fever with allergies

The most important thing is to prevent the allergy itself, its exacerbations. You can prevent the rise in temperature by:

• the fastest relief (stop, stop) of an allergy attack;
• rejection uncontrolled intake antihistamines;
• timely visit to the doctor.

Allergy-center.ru

Is temperature always observed in adults with allergies. What does she testify to? The opinion of experts regarding this symptom.

Clinical picture

Many specialists and patients often face the problem of high temperature when a foreign allergen enters the body.

Such a symptom is not mandatory, it becomes a reason for another concern for physicians.

Is it really the temperature, or could it be something else?

Why does the body react in this way to the allergen?

How dangerous is it for human health?

What happens in the body

When a foreign body appears in the body, they begin to be transmitted nerve impulses with the help of special substances - mediators.

One of them is histamine, which takes an active part in metabolic processes, is responsible for the reaction of gastric secretion and bronchi.

An allergen can cause disturbances in this mediator, resulting in various malfunctions in the work of all internal organs.

There are malfunctions in the pulsation of blood pressure, lacrimation is dotted, excessive amounts are excreted gastric juice, while reducing the "emission" of urine.

An increase in temperature is not a symptom of an allergic reaction.

And if it is observed, then the cause of everything is the inflammatory processes that occur in the body under the action of a viral injection.

In what forms of the disease can rise

AT recent times Allergic manifestations to various objects, products and other factors of human life have become more frequent.

If there is an allergen in the body, then fever is not considered a sign of it.

It indicates the occurrence of concomitant inflammatory processes that negatively affect the functionality of all organs and systems of the patient.

In what cases can the temperature rise with allergies in adults?

1. in the event of a reaction to medications. The clinical picture is very bright, intoxication of the body, itching of the mucous membranes, swelling of the face and extremities, skin rashes, a sharp increase in temperature.
2. with tuberculosis intoxication and other infectious diseases. Temperature around 37.5 degrees can hold long time, indicate the presence of serious disorders in the body. In addition to the "burning" of the body, the disease may be accompanied by excessive sweating, dry cough, general weakness, and disturbances in the digestive tract.
3. with hay fever, allergies to plant pollen, animal hair. If taking antihistamines brings the temperature back to normal, then this is a manifestation of an allergic reaction.
4. insect bites can cause a sharp increase in body temperature. All this indicates a violent reaction of the body to such an allergen. The clinical picture is varied: jumps blood pressure, swelling of the respiratory tract, pain in the bite area, body temperature up to 30 degrees.
5. An allergy can also give a temperature to a food pathogen. In an acute process, not only a high temperature occurs, but also skin itching, aching headache, chills, profuse sweating. The patient's condition requires medical intervention, with such symptoms, you should immediately call an ambulance.
6. when introducing a foreign protein into the body, a vaccine. This reaction is called serum sickness and is accompanied by a temperature of up to 38 degrees. The anaphylactic stage can be fatal.

To what indicators does it rise

With an increase in temperature as a reaction, for any allergen, the indicators may be different.

From 37 to 40 degrees, an allergy against the background of an infectious disease will not disappear so easily, even when the body is exposed to antipyretics.

Unstable body temperature can be a dangerous sign for human health, causing dizziness, shortness of breath, stomach cramps, nausea, and collapse.

Only timely health care can be the key to diagnosing the disease and a speedy recovery.

How to distinguish from other diseases

If we talk about related symptoms, then it is worth noting some differences between similar signs.

1. rubella comparison. The rash occurs on the face, and not all over the body, as with allergies, the disease is accompanied by high fever, which is knocked down by antipyretics, and weakens on the second day if the treatment is carried out effectively.
2. windmill comparison."Children's disease" is celebrated sharp rise temperatures up to 38 degrees, the rash grows over the body and has the form of watery spots. After three days, the blisters begin to subside, and with allergies, they can last for a long time, especially if left untreated

And call an ambulance or go to the hospital, so that the specialist establishes the cause of her rise and prescribes a comprehensive treatment.

The temperature with allergies causes an ambiguous reaction among doctors, since it is known that with a normal allergy there should not be a temperature. In other cases, there are two possible explanations: either you have a common cold, or an atypical allergy. In both cases, treatment should be started as soon as possible.

Temperature with allergies: when and what is caused?

Raise temperatures for allergies can be easily confused with viral infection or a common cold. However, the absence of temperature is characteristic mainly for respiratory allergies. In what cases is a high temperature with allergies possible?

• For example, with a drug allergy, there is just a sharp increase in temperature, complicated by intoxication, itching of the mucous membranes and skin.


• In turn, food allergies can be expressed in completely different ways. In some cases, the "allergic picture" resembles the symptoms sharp pain in the abdomen at high temperature.


• With the introduction of a foreign protein, vaccine, serum, plasma, temperature can also be observed with allergies. This reaction is called serum sickness. Moreover, already in the first of the four stages of allergy, a temperature of up to 38 degrees is observed. The last, anaphylactic stage can be fatal.


• Often a mild temperature is observed with allergies to pollen or animal hair and with allergic dermatosis, coupled with a runny nose, skin inflammation and lacrimation.


• Also, allergies to insect stings can cause fever. It is usually accompanied by swelling and redness, and can also increase pressure and cause pulmonary edema.

Temperature with allergies: how to deal with it?

Doctors say that any temperature, not only caused by an allergic reaction, should not be brought down on the bar below 38 degrees. In other cases the best way is to see a doctor without fail, since the temperature during allergies can be caused by a virus, and you need to know how to treat it.

In other cases, conventional allergy medicines help: Suprastin, Claritin and others. Corticosteroids relieve inflammatory reactions in the body with allergies. They are advised to take even when the symptoms of the allergy itself have decreased. But be warned that steroid drugs have side effects: weight gain and increased pressure.

If the temperature during allergies is caused by drugs, you yourself understand that it is dangerous to use medications, you can aggravate the reaction. Also, do not use hot baths and rubbing, they help only with the first symptoms, and not allergies, but colds.

The most harmless way to lower the temperature, perhaps, is to drink plenty of water (tea with lemon and raspberries, milk with honey). But, again, a food allergy can be caused by just one of these foods. Be careful!

As you understand, fever with allergies is not a common symptom. Either the allergic reaction is aggravated by the virus, or it takes on a special character. Before you start to bring down the temperature yourself, it is best to seek advice from an allergist.

Once again, we emphasize that any treatment, including the treatment of temperature for allergies, is prescribed by a doctor.

Given that the allergic reaction is due to the activity of histamine, antihistamines are most often prescribed, blocking the binding of histamine to the H1 receptors.

Loratadine (Claritin, Clargotil, Lotharen, etc.) trade names) acts quickly, and its therapeutic effect lasts throughout the day. Therefore, the dose for adults and children aged 12 years and over is 10 mg once a day (that is, one tablet), and children under this age weighing less than 30 kg should be given half a tablet per day. It is better for a child under two years of age to give the drug in the form of a syrup.

Among side effects there is a feeling of dry mouth and in rare cases vomiting. It is undesirable for pregnant women to use antihistamines, and in the first trimester it is contraindicated.

Hifenadine (Fenkarol) in tablets of 25 mg for adults is prescribed one or two tablets three times a day; children over 12 years old - one tablet up to three times a day; children 7-12 years old - half a tablet, 3-7 years old - 20 mg per day (divided into two doses). Side effects and contraindications are identical to Loratadine.

Cetirizine (Cetrin, Zyrtec) is available in tablets (10 mg each) - for adult patients and children 12 years of age and older. You can take one tablet once a day or ½ tablet twice a day (with an interval of 8-9 hours). For children 2-6 years old, there are drops that are taken once a day (10 drops each). In addition to dry mouth, there may be side effects in the form of headache, dizziness, increased drowsiness or excitability. In addition to pregnancy, the list of contraindications for cetirizine includes kidney failure.

Levocetirizine (Glentset, Cetrilev, Aleron) - 10 mg tablets - just like Loratadine, should be taken once a day (one tablet). This medicine do not prescribe to children under six years of age, with kidney problems and during the period of gestation and breastfeeding child. This drug may cause nausea and vomiting, dry mouth and itchy skin, increased appetite and stomach pain.

In cases where inflammation of an infectious nature is diagnosed (causing an increase in temperature if patients have allergies), the treatment is carried out by an appropriate specialist with the appointment of the necessary drugs.

An allergy is an inadequate immune response to an irritant. Currently, it is diagnosed in 80% of the world's population. Allergies are classified into various forms depending on the type of allergen, which have their own clinical symptoms. For example, some people have a fever with allergies.

If a person is sick, then an increase in temperature is perceived as a sign of inflammatory changes. With an allergic reaction, the fever is so unexpected that the question involuntarily arises - is there a temperature with allergies, and why does this happen?

It should be noted that this symptom appears infrequently, and it most often indicates the presence inflammatory process third party origin.

Causes

Temperature with allergies in adults and children can be triggered by the factors shown in the table:

Factors	Associated symptoms
food allergens	It is possible that with food allergies, body temperature can rise to 39 degrees. Acute manifestation of food intolerance can provoke increased sweating, skin irritation, rash, fever.
Medications	It proceeds with irritation of the mucous membranes, itching, signs of intoxication and fever up to 39 degrees.
Vaccination	A routine vaccination can cause a rash, swelling and hyperemia at the injection site, as well as a fever of 38 degrees and above. This condition is a medical emergency.
Animal fur	The temperature for allergies in a child and an adult in this situation varies around 37 degrees. Taking antiallergic drugs eliminates the signs of allergies, including subfebrile temperature.
Pollen, ambrosia	If a person suffers from intolerance to pollination and flowering of plants, sometimes his temperature may rise against the background of other manifestations of allergies: rhinorrhea, conjunctivitis, etc.
Insect bites	The temperature usually rises exactly at the site of the bite, which at the same time hurts and swells.

How to determine that the cause of the temperature increase was an allergy?

The temperature with allergies in children and adults is practically no different from a feverish state with colds. But the treatment of these conditions cannot be the same, moreover, if it is wrong, it will certainly affect the person's well-being. Therefore, the true cause of the rise in temperature must be determined precisely.

Disease	Characteristic features
Allergy	If we are really talking about an allergic condition, then, in addition to the fact that allergies can cause fever, there are other accompanying symptoms of this condition. Interaction with an allergen ends with a clinical picture known to every allergy sufferer: skin itching, sneezing, red skin rashes, allergic rhinitis and much more.
SARS and FLU	With infections of the respiratory tract of viral or bacterial origin, the temperature is always accompanied by a sore throat, signs of intoxication of the body, headache, that is, symptoms that have nothing to do with allergies.

It should be noted that an allergic reaction is formed quite quickly - its signs can appear already a couple of minutes after contact with the allergen. In turn, a cold begins gradually, it is characterized by a staged development, and, on average, lasts at least 7 days.

Elevated temperature with allergies, growing in a short time, means a pronounced reaction of the immune system to the aspect that irritates it. This condition can be dangerous development anaphylactic shock etc. If, with the symptoms of an allergy, there is swelling of the face and shortness of breath, developing into suffocation, general deterioration well-being, necessary urgent care doctor.

Features of temperature for allergies in children

The immune system of a child is not as perfect as that of an adult. Therefore, it is much more difficult for her to be able to resist external pathogenic factors, in particular, allergic irritants. For this reason, allergic reactions occur more often and more acutely.

An allergy with a temperature is more dangerous for a child, as it can lead to serious complications. Therefore, if you suddenly develop a fever after a vaccination, insect bite, or medication, you should not hesitate to seek medical help.

Sometimes the temperature with allergies in children rises due to its consequences. For example, delicate skin at this age is more difficult to recover from traumatic factors. If the signs of allergy pass slowly, the itching continues for a long time (most often due to inadequate medical treatment or its complete absence), then foci of inflammation form at the site of the rash, which become secondarily infected and are complicated by the appearance of purulent contents. If there are many such rashes, the body temperature rises, but this will not happen because of the allergy itself, but as a result of the inflammation that has arisen against its background.

What should be the first aid?

Whether an allergy can give a temperature is an extraordinary question only until the moment when the allergic person himself encounters this condition. If appropriate measures are not taken, the temperature may continue to rise, which will adversely affect well-being. To correct the situation, you should use the following tips to reduce the heat.

1. Eliminate or minimize contact with an irritating factor.
2. Take an antihistamine that was previously prescribed by your doctor. If no medical treatment has been carried out before, you can take Suprastin, Zyrtec or Loratadine at the dosage recommended for age. Most often, the effect of an antihistamine completely eliminates not only the clinical manifestations of the pathology, but also the temperature that accompanies it.
3. If an insect bite was recorded and an allergic reaction developed almost immediately, it is necessary to rinse the bite site with plenty of running water as soon as possible and treat it with any anti-allergic ointment. This will help relieve the local inflammatory process.

1. To improve overall well-being, you can take enterosorbents (Activated charcoal, Enterosgel, etc.), which help to eliminate toxins from the body. Also, for this purpose, it is advisable to drink clean non-carbonated water in sufficient quantities.
2. If there is a suspicion that the allergy is caused by a drug, it is necessary to stop using it for at least the next period of time. It is recommended to consult your doctor, who will select an analogue of this drug and exclude additional causes that can cause an increase in temperature in the future.

Treatment

The answer to the question - can there be a temperature with allergies and what should be the treatment, all allergy sufferers should know. If an adult or a child has a fever and all the signs of an allergy are present, first of all, you need to contact a specialist. The main thing is to consult with him in a timely manner, since a further increase in temperature values ​​\u200b\u200bis not excluded, and then complications cannot be avoided.

If the temperature remains within subfebrile condition or slightly exceeds 37 degrees, there is no need to take an antipyretic drug. If its values ​​\u200b\u200bexceeded the mark of 38 degrees and continue to grow, you can give a drug to relieve heat before the doctor arrives. It can be Paracetamol, Nurofen, etc.

To combat the allergy itself, experts prescribe antihistamines. Their action is to inhibit the biologically active substance, which provokes the symptoms of pathology. Allergy medications come in three generations. This case requires the use of first generation drugs, as they are stronger and give a quick effect. Their list includes Fenkarol, Suprastin and others.

If the skin begins to pour out, for the treatment of a rash in adults, preference is given to hormonal ointments (for example, Hydrocortisone, etc.). In childhood, it is desirable to use non-hormonal agents, for example, Panthenol, Bepanten, etc.

Prevention

To prevent the development of allergies with symptoms of elevated body temperature, it is necessary to exclude contact with objects or refuse to use food products, which provoke a deterioration in general well-being and cause an inadequate reaction from the immune system. This is the primary and most important method of preventing any allergic disease.

After that, you can pay attention to healthy lifestyle life, a balanced diet, strengthening immunity, hardening and good sleep.

Fever with allergies often occurs in children, and it is associated with an overabundance in the body annoying factors. The immune system tries to neutralize their pathogenic effect, and throws out a huge amount of histamine, so already 10 minutes after interacting with allergens, the induced process manifests itself in all colors.

Listed the most dangerous symptoms, which may exist for a given pathological process, is a fever with a thermometer reading of 39°. This condition provokes an ambiguous reaction from many organs and systems of the body, so any complications against this background are not excluded. What to do? Before you start sounding the alarm, it is strongly recommended to take an antihistamine and antipyretic. In the absence of signs of improvement in well-being, medical attention is needed.
