Naphcon-A

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.

Do NOT use Naphcon-A if:

  • you are allergic to any ingredient in Naphcon-A
  • you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (eg, phenelzine) within the last 14 days

Contact your doctor or health care provider right away if any of these apply to you.
