Allergen specific immunotherapy 


Allergen specific immunotherapy is the repeated administration of allergen to induce immunological tolerance and relieve symptom impact. Immunotherapy improves quality of life of allergic patients and is cost-effective over a period of 6 years.

Allergen specific immunotherapy can be self-administered at home as fast dissolving tablets or liquid drops to be placed under the tongue, or it can be received as injections in the lower part of the skin under supervision in a doctor’s office.

A course of immunotherapy is 3 years in duration. Treatment under the tongue, with tablets or drops, is administered daily, whereas injection treatment has 2 phases: an initial up-dosing phase with weekly injections and an extended maintenance phase with injections every 6 weeks.

Allergen specific immunotherapy cures approximately 40% of patients, whereas another 40% experience a substantial reduction in symptom severity as well as symptom duration. Approximately 20% of patients report no effect of treatment. Immunotherapy has effect on all allergic symptoms in one treatment.
