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

Stop the Naphcon A: Excessive use of eye drops containing preservatives can cause a condition called "medicamentosa".

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

Can I take Benadryl (diphenhydramine) and also use allergy eye drops (naphazoline & pheniramine)?

Can I take Benadryl (diphenhydramine) and also use allergy eye drops (naphazoline & pheniramine)?

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
