Lotemax might also work for your allergies because it is an ophthalmic corticosteriod which is used to treat itching, swelling, redness or irritation caused by bacteria, after surgery or even certain allergies. But to make sure that it is right for the type of eye allergy you have, talk to your health care provider. If it is, then you don't need to use Pataday. However, there are no known interactions with Pataday, so basically it is okay to use. Consult your doctor before doing so.
