What is Tanabid SR?
Brompheniramine is an antihistamine that reduces the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.
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 and phenylephrine is used to treat nasal congestion, sneezing, itching, watery eyes, and runny nose caused by allergies, hay fever, and the common cold.
Brompheniramine and phenylephrine may also be used for other purposes not listed in this medication guide.
