Can we cure an allergy?

One question remains: can one cure an allergy? To change the course of allergic disease, it is possible to resort to specific immunotherapy, or "desensitization": this technique can induce tolerance to one or more allergens. The progress of recent years has enhanced the effectiveness of these treatments with better purification of allergens and the administration of some sublingually. Subcutaneous injections take place once a week for 3 months, then once a month for 3 years.

Subcutaneous immunotherapy helps control the signs of allergies in more than two-thirds of people with allergic rhinitis and prevents the development of bronchial asthma and broadens the spectrum of allergies to others allergen over time. The desensitization works all the better that it is initiated soon after the development of the signs. In case of recurrence after desensitization, if the first immunotherapy has been effective, it is possible to redo it.
