Using cosopt eye drop for glaucoma and have a sulfa allergy. what are some alternatives?

Sulfa, cosopt: Depending on what your target range of pressure is, you could try timolol, alphagan, xalatan, (latanoprost) lumigan, travatan, xioptan, or combigan. Pilocarpine is also available but not nearly as convenient to use. Then there is laser treatment too. Incisional surgery for glaucoma would be for people whose eye pressure is suboptimally controlled despite maximal tolerated medical &/or laser treatment.
