Naphazoline and pheniramine ophthalmic is used to provide temporary relief from common allergy-related symptoms in the eyes, including redness, swelling, itching, and excessive tearing. Naphazoline functions as a decongestant and falls under the category of sympathomimetic amines. Its mechanism involves temporarily constricting the blood vessels in the eye. Pheniramine acts as an antihistamine, working to obstruct specific natural compounds that trigger allergic responses.
