Naphcon A Eye Drops
Anti-allergic: Both drops contain a mild vasoconstrictor (naphazolamine) which can help whiten up allergically affected eyes. Naphcon-a, an alcon company brand name, also contains pheneramine, which is a mild anti-histamine. So plain naphcon can briefly eliminate the redness but does not treat anything while naphcon a can decrease the redness but also treat the allergy. Read more

How do I reverse redness in both eyes from eye drop over use, caused by months of using naphcon a eye drops?
Stop the Naphcon A: Excessive use of eye drops containing preservatives can cause a condition called "medicamentosa". Treatment involves stopping the offending eyedrop and switching to an artificial tear that does not contain preservatives. The labeling should state: "preservative free". Since many serious eye problems can cause redness you should contact a local eye doctor as soon as possible. Read more

Individuals vary.: I love Naphcon-A too! Very, very inexpensive as well. 2nd generation antihistamines, like ketotifen may be less effective than some 1st generation antihistamines like Naphcon-A (2 drug combo. Interestingly, if you took the oral equivalent of pheniramine (1 of the drugs in it) it can be very sedating, but this is not as much of a problem when used in the eyes. Read more

Yes: Both these drops are vaso-constrictors that constrict the blood vessels on the surface of the eye. They should only be used for a short time. Long term usage can cause rebound vaso-congestion which results in worsening redness in the eyes when the drop is not used. Using it more than a few times a day for a few weeks is likely too long.

Not really: These drops are vaso-constrictors that constrict the blood vessels on the surface of the eye. They should only be used for a short time.

Artificial tears: Naphcon is for mild allergies. This may or may not be the reason for your red eyes. Often it is just dryness. This is usually worse when you wake up cause your eyes don't get lubricated well while sleeping. Try artificial tears doing the day and an artificial tear ointment at night. If you have decreased vision, pain, discharge, or persistent redness, get an eye exam. Read more
Find the Cause: Naphcon-a merely treats a symptom! A proper eye exam is necessary to determine the underlying cause of redness. The most common causes are dry eye, ocular allergy, blepharitis and viral conjunctivitis. There are also some more rare causes of redness that need to be ruled out. Read more
Avoid regular use: Both drops contain naphazoline, which is a potent blood vessel constrictor. This is what "gets the red out". If used too much it can causes rebound redness. Naphcon a contains an antihistamine as well. Try a plain allergy eye drop like zaditor, (ketotifen) alaway, or zyrtec drops. Read more
