NasOpen

Generic name: Chlorcyclizine And Pseudoephedrine
Drug class: Upper respiratory combinations

Usage of NasOpen

Chlorcyclizine is an antiHistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of sneezing, itching, watery eyes, and runny nose.

PseudoEphedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

NasOpen is a combination medicine used to treat runny or stuffy nose, sneezing, itching, watery eyes, sinus congestion, and other cold or allergy symptoms.

NasOpen may also be used for purposes not listed in this medication guide.
