Can I Use Allergy Eye Drops If I Wear Contact Lenses?

Get the facts before your next allergy attack

Usually. People who suffer from eye allergies experience redness and itching of the eyes. Treatment of eye allergies may include antihistamine pills, nasal sprays, as well as topical allergy eye drops. I am frequently asked by my patients who suffer from eye allergies if they can continue to wear their contact lenses when using allergy eye drops.

Most allergy eye drops, including over-the-counter ones such as Zaditor (ketotifen) and prescription forms such as Pataday (olopatadine) and Optivar (azelastine), can be used with soft contact lenses.

The prescribing information for all of these eye drops recommends placing the drops into the eyes while not wearing the contact lenses, then waiting at least 10 minutes before inserting the contact lenses. The reason for this is to prevent the anti-bacterial preservative, benzalkonium chloride, from absorbing into the contact lenses.​​​

Of course, before using these drops, you should be sure that your eye redness is truly due to allergies and not a reaction to the contact lenses. If you're not sure, speak to your doctor.
