Return to top Atarax is an antihistamine used to relieve the symptoms of common anxiety and tension and, in combination with other medications, to treat anxiety that results from physical illness. It also relieves itching from allergic reactions and can be used as a sedative before and after general anesthesia. Antihistamines work by decreasing the effects of histamine, a chemical the body releases that narrows air passages in the lungs and contributes to inflammation.
Antihistamines reduce itching and swelling and dry up secretions from the nose, eyes, and throat.
