Question: I Have Eye Allergies. Can I Just Use an Over-the-Counter Eye Drop?
Answer: Certain kinds of over-the-counter eye drops can only be used for short periods of time. Most over-the-counter allergy eye drops contain topical decongestants, like those found in Visine (naphazoline), which should only be used for a few days at a time. When topical decongestants are used long-term, a medical condition called conjunctivitis medicamentosa can develop. Symptoms may include an increase in eye redness and irritation, with more dependence on the eye drop for relief.
Zaditor/Alaway (ketotifen), a topical antihistamine and mast cell stabilizer eye drop, is now available over-the-counter for the treatment of eye allergies. This medication can be used long-term without the potential side effect of conjunctivitis medicamentosa.
