Expert advice for Timolol

  • Timolol helps lower high pressure in the eye and reduces the risk of vision loss.
  • Apply pressure on the corner of the eye (close to the nose) for about 1 minute, immediately after instilling the drop.
  • Wait for at least 5-10 minutes before delivering the next medication in the same eye to avoid dilution.
  • Notify your doctor if you have lung or heart diseases as Timolol may worsen these conditions.
  • Stinging sensation may occur for 1-2 mins. Notify your doctor if it persists for longer.
  • Make sure to use within 4 weeks of opening the bottle.

Frequently asked questions for Timolol


Q. What does Timolol do?

Timolol reduces the pressure inside the eyes, known as intraocular pressure. This helps to reduce the risk of damage to the optic nerve which is responsible for normal vision. If the pressure in the eye is not controlled, it can gradually with time lead to blindness. Timolol effectively controls ocular hypertension and certain types of glaucoma by decreasing the pressure in the eyes.

Q. How should you use Timolol?

Timolol comes in two variants: a liquid solution and an extended-release (long-acting) gel-forming solution (liquid that thickens to a gel when instilled in the eye). Timolol eye drops are usually instilled once or twice a day at evenly spaced intervals, until the pressure in the eye is controlled (about 4 weeks). After that, it can be instilled once a day or as advised by the doctor. Timolol gel-forming solution is usually instilled once a day. Follow the directions of your doctor carefully, and ask your doctor to explain any part you do not understand. Use Timolol in the dose and duration advised by your doctor.

Q. Can I stop Timolol if I am fine now?

No, you should not stop using Timolol without consulting your doctor. If you stop taking this medicine suddenly, the pressure in your eyes may not be controlled which may increase the risk of loss of sight.

Q. When should I seek a doctor’s advice?

You should contact your doctor immediately if you develop an eye infection, conjunctivitis or an eyelid reaction. Also, you should inform the doctor if you have an eye injury or eye surgery. Discuss with your doctor if you have to continue using Timolol.

Q. Can I use Timolol with contact lenses?

No, you should remove your contact lenses before instilling Timolol. You can re-insert the lens 15 minutes after using Timolol. Contact your doctor if there is any eye irritation that persists.
