What is SymPak II?

Brompheniramine, chlorpheniramine, and methscopolamine are antihistamines that reduce the effects of the natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

Phenylephrine and pseudoephedrine are decongestants that shrink blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

SymPak II is a combination medicine used to treat runny or stuffy nose, sneezing, itching, watery eyes, and sinus congestion caused by allergies, the common cold, or the flu.

This combination medicine may also be used for purposes not listed in this medication guide.
