1) For people who suffer from allergic rhinitis, sublingual desensitization reduces symptoms and medication use. Symptoms of rhinoconjunctivitis were reduced by about 37%, nasal obstruction of 59% and 50% watering (1).

2) The improvement of symptoms is maintained for several years after the sublingual desensitization. But he must know that relapse is even earlier than the duration of the desensitization was short.

3) It is especially effective in cases of allergy to pollen, but is also used in cases of allergy to house dust and mites.

4) Prior to desensitization, it is essential to an allergy testing to identify the allergen.

5) The desensitization may be ineffective if polysensitisation. It is therefore intended for individuals allergic to a specific allergen.

6) sublingual desensitization was well tolerated and rarely require discontinuation of treatment. The most common reactions are local, they occur mainly in early treatment and were mild to moderate swelling of the mouth, oral pruritus (itching), swelling of the tongue, throat irritation and sometimes ocular itching.

7) In asthmatics, the results of desensitization are more nuanced (2). Nevertheless, we obtain an improvement of symptoms (bronchial hyperresponsiveness).
