timolol is a glaucoma medicine. Used for treating glaucoma, as a daily eye drop to lower intraocular (eye) pressure, not for the numbing part of the test.

Prescribed as a single medicine (usually timolol maleate), generic, or under the brand names Betimol, Istalol, Timoptic, and Timoptic-XE.


It is also one of the two components in the glaucoma medicine Cosopt, just recently gone generic so now labeled dorzolamide hydrochloride and timolol maleate solution.

You will not be given timolol as part of a pressure check or pupil dilation at an office visit. Not its purpose. No need to worry about that one.
