antihistamine

Any substance that counteracts the effects of histamine. Antihistamines may occur naturally or they may be synthesized.

H1 antihistamines are used to relieve allergies, alleviating symptoms such as runny nose, itching, swelling, or asthma. H2 antihistamines suppress acid production by the stomach, and are used in the treatment of peptic ulcers, often making surgery unnecessary.
