Benefits of Theot Ophthalmic Solution

Glaucoma
Theot Eye Drop belongs to a group of medicines called beta-blockers. It is used to reduce pressure in the eyes (ocular hypertension). This pressure can lead to an illness called glaucoma. If the pressure in your eye is too high, it can damage your sight. This medicine works by helping the fluid to flow from inside the eye into your bloodstream. It may be used alone or with other eye drops. Do not use it too often as that can make it less effective. You should only use it in the affected eye and take it regularly as prescribed by your doctor. Most people with glaucoma or high pressure in the eyes do not feel sick. If you stop taking it, the pressure in your eye will not be controlled. This could lead to a loss of sight.

Frequently asked questions

What does Theot Eye Drop do?

Theot Eye Drop 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. Theot Eye Drop effectively controls ocular hypertension and certain types of glaucoma by decreasing the pressure in the eyes.

How should you use Theot Eye Drop?

Theot Eye Drop 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. Follow the directions of your doctor carefully, and ask your doctor to explain any part you do not understand. Use Theot Eye Drop in the dose and duration advised by your doctor.

Can I stop Theot Eye Drop if I am fine now?

No, you should not stop using Theot Eye Drop 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.

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 Theot Eye Drop.

Can I use Theot Eye Drop with contact lenses?

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