Success in the treatment of allergic urticaria by 90% depends on whether it will be possible to identify the cause - a specific allergen, and eliminate it. With the constant presence of an irritant factor in the blood, there will be a sufficient number of immunoglobulins, which are detoxifying. This means that the rash does not go away.

  4. In the case of chronic urticaria, autolymphocytotherapy is prescribed-a six-fold subcutaneous injection of the lymphocytes of the patient's own blood.

Compliance with all treatment options eliminates the symptoms of acute urticaria. On the skin there are no traces, edemas of mucous and itching disappear.

If urticaria causes a lot of factors or contact with a significant factor can not be ruled out, then it is necessary to take antihistamines (claritin, diazoline, telfast). For particularly severe forms of urticaria, short-term glucocorticoid drugs are used.
