Generic Name: naphazoline/pheniramine (naf-AZ-oh-leen/fen-EAR-ay-meen)
Brand Name: Examples include Naphcon-A and Visine-A
Naphcon-A is used for:
Temporarily relieving itchy, red eyes caused by allergies to things such as pollen, ragweed, grass, or animal hair and dander.
Naphcon-A is a decongestant and antihistamine combination. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery, itchy eyes. The decongestant constricts (narrows) the blood vessels, which reduces eye redness.
