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.

Society and culture

edit

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.[2]

Brand names

edit

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

Side effects

edit

Continuous and/or cumulative use of anticholinergic medication, including first-generation antihistamines, is associated with a higher risk of cognitive decline and dementia in older people.[3][4]
