Carbinoxamine, sold under the brand name Arbinoxa among others, is a medication use to treat allergic reactions including hay fever, allergic conjunctivitis, and hives.[1] It is taken by mouth.[1] It should not be used the common cold or in children under 2 years.[1]

Carbinoxamine was patented in 1947 and came into medical use in 1953.[2] It is available as a generic medication.[3] In the United States 60 pills of 4 mg costs about 20 USD as of 2021.[3]

Medical uses


It is usually taken at a dose of 4 to 8 mg three to four times per day.[1]

Society and culture

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.

In June 2006 the FDA announced that more than 120 branded pharmacy products containing carbinoxamine were being illegally marketed and demanded they be removed from the marketplace. This action was precipitated by twenty-one reported deaths in children under the age of two who had been administered carbinoxamine-containing products. Despite the fact that the drug had not been studied in this age group, a multitude of OTC preparations containing carbinoxamine were being marketed for infants and toddlers. At present, all carbinoxamine-containing formulations are approved only for adults or children ages 3 or older.[4]

Brand names include Clistin, Palgic, Rondec, Rhinopront, Ryvent.
