Timolol is prescribed to lower blood pressure in patients with high blood pressure (hypertension).

Off label uses include the treatment of hypertrophic cardiomyopathy and mitral valve prolapse.

WARNING: (BLACK BOX WARNING):

Stopping timolol abruptly may worsen chest pain from ischemic heart disease and may precipitate a heart attack. The dose of beta-blockers should be reduced gradual over 1 to 2 weeks when discontinuing treatment, even in patients who only have hypertension. If chest pain occurs the beta blocker should be restarted, at least temporarily, and symptoms should be treated appropriately.

Beta-blocker treatment should not be interrupted or discontinued without a doctor's advice.

Hypersensitivity to catecholamines (for example, epinephrine) may occur when discontinuing beta-blockers.

abdominal cramps, diarrhea, constipation, fatigue, insomnia, nausea, and vomiting.
