The finest and the utmost scholarly method of defensive action and management of an allergy is the avoidance of the allergen. Drugs can also aid treat the symptoms of an allergic reaction, but they will not cure the allergy. Just check with the doctor or clinician before recommending certain medications for allergic reactions. Example: Antihistamines, Decongestants, Leukotriene receptor antagonists, or anti-leukotrienes and Steroid sprays. The allergic reaction is a non-entity, but the hypersensitization of the foreign molecules can also be treated by Immunotherapy and that is used only when the allergy is very high and severe.
