Cosopt Eye Drop 5 ml is used to treat open-angle glaucoma and ocular hypertension (high pressure in the eyes). Cosopt Eye Drop 5 ml is generally used when no other medication effectively treats glaucoma or ocular hypertension. Glaucoma is an eye condition that causes damage to the optic nerve (essential for good vision) due to abnormally increased pressure in the eye. Ocular hypertension is increased pressure in the eye due to poor drainage of aqueous humour (fluid in the eye that maintains normal pressure by its continuous flow).

Cosopt Eye Drop 5 ml contains Dorzolamide and Timolol. Dorzolamide is a topical carbonic anhydrase inhibitor, and Timolol is a topical beta-blocker. Both help decrease the secretion of aqueous humour (natural fluid present in the eye) by the eye's ciliary body, thereby causing a decrease in eye pressure.

Cosopt Eye Drop 5 ml is taken with or without food in a dose and duration as advised by the doctor. The doctor will adjust your dose according to your condition and response to the medicine. In some cases, you may experience itching, stinging sensation, burning sensation in the eye, redness, blurred vision, tiredness, drowsiness, headache and dryness in the mouth. Most of these side effects of Cosopt Eye Drop 5 ml do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

Try not to stop taking this medicine of your own. You should not use Cosopt Eye Drop 5 ml without consulting your doctor if you have an eye infection, allergies, closed-angle glaucoma, thyroid diseases, asthma, chronic obstructive pulmonary disease (COPD), heart, liver and kidney diseases, diabetes, high or low blood pressure, depression, Raynaud's phenomenon (numbness in various parts of the body) and slow heartbeats that make you faint. Using Cosopt Eye Drop 5 ml during breastfeeding is unsafe since Timolol can pass into breast milk and harm a nursing baby. Check with your doctor before using Cosopt Eye Drop 5 ml if you are pregnant, breastfeeding, or taking other prescribed or non-prescribed medicines. If you use more than one ophthalmic drug, install each medication with a five-minute gap.

Cosopt Eye Drop 5 ml is an ophthalmic medication. It effectively treats open-angle glaucoma and ocular hypertension (high eye pressure). Cosopt Eye Drop 5 ml consists of Dorzolamide and Timolol in the form of ophthalmic solution (eye drops). Dorzolamide is a topical carbonic anhydrase inhibitor, and timolol is a topical beta-blocker. Both help decrease the secretion of aqueous humour (natural fluid present in the eye) by the ciliary body in the eye, thereby causing a decrease in eye pressure.

Before taking Cosopt Eye Drop 5 ml, let your doctor know if you have a history of eye infection, allergies, closed-angle glaucoma, thyroid diseases, asthma, chronic obstructive pulmonary disease (COPD), heart, liver, and kidney diseases, diabetes, high or low blood pressure, depression, Raynaud's phenomenon (numbness in various parts of the body), and slow heartbeats that make you faint. Regular monitoring of blood sugars may mask the signs and symptoms of acute hypoglycaemia.

Glaucoma: Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged. It's usually caused by fluid building up in the front part of the eye, which increases pressure inside the eye. Glaucoma can lead to vision loss if not diagnosed and treated early.

Open-angle glaucoma: Open-angle glaucoma is a life-long condition and the most common type of glaucoma. It is caused by the clogging of the drainage angle between the iris and cornea, which leads to the blockage of eye fluid and increases eye pressure.

Ocular hypertension: Ocular hypertension is the building up of pressure in the eye caused by poor drainage of the aqueous humour (fluid inside the eye that maintains normal pressure).
