Naphcon A is an over counter eye medication used to provide temporary relief from eye redness and itching caused by allergies such as pollen, dust, or animal dander. Naphcon-A is a combination medication that contains naphazoline hydrochloride and pheniramine maleate.
Naphazoline is a vasoconstrictor that works by narrowing the swollen blood vessels in the eye, which can cause eye redness. Pheniramine is an antihistamine that blocks the action of histamine, a substance that the body releases in response to an allergic reaction, which can cause eye itching and irritation. The combination of these two medications in Naphcon-A provides temporary relief from the symptoms of eye allergies such as itching, redness, and irritation. However, Naphcon-A is not intended for long-term use without consulting with a healthcare professional.
Uses and Dosage
To properly apply Naphcon-A Eye Drops, start by washing your hands to avoid contamination. Be sure not to touch the dropper tip or let it touch any surface or your eye. Always inspect the product before using it to ensure the liquid is clear and has not changed color. If the liquid appears cloudy, do not use it. Keep the medicine out of reach of children and pets.
Use the drops up to 4 times a day in the affected eye(s), unless otherwise directed by your doctor. Tilt your head back, hold the dropper directly over the eye, and place 1 drop into the lower eyelid pocket. Close your eyes gently for 1 to 2 minutes and apply gentle pressure with a finger near the corner of the eye to prevent the medication from draining out. Avoid blinking or rubbing the eye and repeat the steps if the dose is more than 1 drop, or if both eyes are being treated.
Do not rinse the dropper and always replace the dropper cap tightly after each use to prevent contamination. If you are using other types of eye medication such as drops or ointments, wait at least 5 minutes before using Naphcon-A Eye Drops. Use eye drops before applying eye ointments to allow the drops to fully take effect.
Taking too much medication may result in increased eye redness which is due to the "rebounds" effect when the drug wears off. If this occurs, seek your doctor's advice. Do not use this medication for more than 3 to 4 days. If there is no improvement or the condition gets worse after 72 hours, stop using this medication and seek immediate medical attention as you may have a serious medical problem.
