Allergen avoidance is essential for some forms of allergy such as food allergy and allergic contact dermatitis, and is helpful in respiratory allergy.

Special milks for cow's milk allergies are formulations made from specially processed milk proteins. Some of them are used not only for treatment but also for the prevention of allergies.

Medicines play a central role in controlling allergic symptoms. Their role is to reduce the allergic inflammation and relieve the symptoms which are nothing but the effects of the various substances released as a result of this inflammation.

Unfortunately, prevention is not always possible and drug therapy, however effective, does not treat the cause of the allergy. The only therapeutic approach that addresses the allergy at its root as it modifies the patient's immune system for the patient's long-term benefit is immunotherapy.
