Timolol vs. Combigan

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Timolol and Combigan (brimonidine/timolol) are both eye drop medications used to lower eye pressure in people with glaucoma or ocular hypertension. Timolol is a beta blocker that works by reducing the amount of fluid in the eye. Combigan, on the other hand, is a combination of two medications: timolol and brimonidine, an alpha agonist that works by reducing fluid production and improving fluid draining in the eye. Both are available in brand and generic forms. Both medications are typically used twice a day, but Combigan may have more side effects due to its combination of active ingredients. Additionally, while both medications can affect blood pressure and heart rate, Combigan has a higher risk of causing these issues.
