What is carbinoxamine?
Carbinoxamine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
Carbinoxamine is used to treat sneezing, runny nose, itchy or watery eyes, hives, skin rash, itching, and other symptoms of allergies and the common cold.
Carbinoxamine may also be used for other purposes not listed in this medication guide.

Deaths have been reported in children under 2 years old who had received carbinoxamine, although it has not been determined that carbinoxamine was the cause of these deaths. Talk with your doctor about other FDA-approved products available for use in young children with cold or allergy symptoms.
