Definition


An antihistamine is a medication used to counteract the effects of histamine, a molecule which has numerous effects and which is widely dispersed in the case of an allergic reaction. Antihistamines can be prescribed in connection with allergic rhinitis, allergic conjunctivitis, allergic dermatological illnesses, or urticaria. This molecule allows us to fight against cutaneous itching. Antihistamines are also used for severe and brutal allergies occasionally responsible for anaphylactic shock, which can become life-threatening.
