What is Opcon-A?
Naphazoline is a vasoconstrictor. It works by narrowing swollen blood vessels in the eyes to reduce eye redness.
Pheniramine is an antihistamine that reduces the effects of natural chemical histamine in the body. Histamine can produce symptoms of itchy or watery eyes.
Opcon-A (for the eyes) is for temporary relief of minor eye redness or itching caused by ragweed, pollen, grass, or animal dander and hair.
Opcon-A may also be used for purposes not listed in this medication guide.
