What is brompheniramine, chlorpheniramine, methscopolamine, phenylephrine, and pseudoephedrine?
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).
