Carbinoxamine is an antihistamine and anticholinergic agent. It is used for hay fever, vasomotor rhinitis, mild urticaria, angioedema, dermatographism and allergic conjunctivitis. Carbinoxamine is a histamine antagonist, specifically an H1-antagonist. The maleic acid salt of the levorotatory isomer is sold as the prescription drug rotoxamine.

It was patented in 1947 and came into medical use in 1953.^[1] It was first launched in the United States by the McNeil Corporation under the brand name Clistin. Carbinoxamine is available in various countries around the world by itself, combined with decongestants such as pseudoephedrine, and also with other ingredients including paracetamol, aspirin, and codeine.
