In brief: Unlikely

Studies have shown that having a sulfa structure in a drug rarely causes problem in people with a true sulfa allergy.

In brief: Possibly

Cosopt is a combination eye drop containing dorzolamide and timoptic (timolol).
Dorzolamide has a "sulfa group" in its chemical formula. Some patients, not all, who have a sulfa allergy are allergic to it. This present as a red, itchy eye and surrounding skin. If this happens, stop the drop and call your doctor. Go to the er with difficulty breathing or swallowing.
