Patanol

Alcon's prescription antihistamine eyedrops: Patanol (and probably Pataday as well) have not been confirmed corn-free, nor confirmed corn.

A discussion on Delphi - Avoiding Corn, concerning Patanol increases our suspicions that it contains corn.

It is unsure which ingredient(s) in the Patanol would be corn-derived, but the benzalkonium chloride may be the culprit.

Use extreme caution before using this product with a severely sensitive corn-allergic.
