What is brompheniramine/carbetapentane/phenylephrine?
Carbetapentane is a cough suppressant.
Brompheniramine is an antihistamine. It blocks the effects of the naturally occurring
chemical histamine in the body. Histamine can produce allergy symptoms such as sneezing,
runny nose, and watery eyes.
Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated
blood vessels can cause nasal congestion (stuffy nose).
The combination of brompheniramine, carbetapentane and phenylephrine is used to treat
cough and nasal congestion associated with allergies or the common cold.
Brompheniramine, carbetapentane and phenylephrine may also be used for purposes other
than those listed in this medication guide.
