Beta-blocker (eye drop for glaucoma)
Last reviewed July 2026
Who is this for?
Timolol is an eye drop medication that works by reducing the pressure inside your eye. It belongs to a group of medicines called beta-blockers, which slow down the production of fluid in the eye so pressure goes down.
Blocks beta-1 and beta-2 adrenergic receptors in the eye, reducing aqueous humor production and increasing uveoscleral outflow, thereby lowering intraocular pressure.
High eye pressure (glaucoma), elevated pressure inside the eye (ocular hypertension)

If you miss a dose, put in the drop as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not put in two drops at once to make up for the one you missed.
Always buy your eye drops from a reputable pharmacy and avoid roadside sellers or open markets where storage conditions are poor and fake drugs are common. Do not share your eye drops with anyone, even if they have similar symptoms, to avoid spreading eye infections. If you wear contact lenses, remove them before putting in the drops and wait at least 15 minutes before putting them back in.
If you are taking blood pressure medicines (especially other beta-blockers like atenolol or propranolol), timolol eye drops can make your blood pressure or heart rate drop too low, so tell your doctor. Calcium channel blockers like amlodipine or verapamil can also interact and cause heart problems. Alcohol may increase dizziness and low blood pressure when combined with timolol.

Is it safe to take Timolol with your other drugs?
