What if you are allergic after insect bites?

Insect bites can cause not only itching and severe discomfort, but also allergies. What to do if such a reaction occurs?

What insect bites can cause allergies?

Allergies can cause bites of almost any insect. But most often the reactions develop after contact with the stinging insects, since they can inject poison, which the body will perceive as a foreign substance and will try to remove with the help of secreted mast cells substances that are mediators of inflammation (this includes histamine). So, bites of wasps, bees, and bumblebees cause severe discomfort.

But blood-sucking insects can also cause a lot of trouble, because some of them, firstly, violate the integrity of tissues and immerse the sucking part of the oral apparatus (usually the proboscis) under the skin, and secondly, can release special substances that prevent blood coagulation or have painkillers properties.And such insects include mosquitoes, mites, lice, midges, gadflies, bugs, and so on.

In general, the bite of almost any insect can lead to allergies, because the reaction to the contact of tissues with it will depend on the individual characteristics of the organism.


Symptoms of an allergic reaction to insect bites can be as follows:

  • The most common symptom is itching, and quite strong.
  • At the site of the bite, as a rule, there is swelling, which can spread to a very extensive area. In some cases, edema can take a significant area of ​​the body, for example, a whole limb or, for example, a face.
  • Allergies are often accompanied by redness.
  • There may be hyperemia, that is, a localized increase in the temperature of the skin, extending to the bite mark and the surrounding area (touch this place will be hot).
  • Sometimes urticaria develops, that is, skin rashes.
  • If the reaction is acute and severe, it sometimes affects almost the entire body. In such cases, Quincke edema may occur (angioedema, usually extending to the mucous membranes or the face area),feverish conditions, respiratory or palpitations, reduced blood pressure, weakness and dizziness, pre-unconscious states, and even anaphylactic shock.

How to solve a problem?

What if there is an allergy to insect bites? It is necessary to act in stages:

  1. The first step is to treat the site of the bite with any anesthetic, such as alcohol. This will partially remove the penetrated substances under the skin and reduce the risk of developing the reaction.
  2. If the allergy began to develop, then the bite site should be treated with a local antiallergic agent. The most popular will be described below.
  3. If severe edema has developed, then something cold should be applied to this area. Such an impact will not only reduce puffiness, but also slightly relieve itching and pain.
  4. It is not necessary to comb the bite site, such a mechanical effect on the tissue will cause the spread of substances that cause allergies, as a result, the reaction will be even more pronounced.
  5. In case of a general allergic reaction, a broad-spectrum antihistamine should be taken.
  6. If the condition worsens, you should consult a doctor. Allergies are especially dangerous in children, so the child should in any case be shown to a specialist, and as soon as possible.

Local antiallergic drugs

The most commonly used drugs are classified as antihistamines, that is, blocking H1-receptors and preventing the development of inflammation. These include such as gel "Fenistil", "Psilo-Balsam".

If the reaction has already begun to develop rapidly, then there is no point in blocking the H1 receptors, this will not eliminate the manifestations. And in this case, you should use hormonal drugs intended for external use. Usually they consist of glucocorticoids, and on the basis of these components are made such means as ointment “Lokoid” or “Elokom”, cream “Advantan”,

  • Use gruel made from sea buckthorn berries.
  • Make a compress using a burdock or plantain leaf.
