Delzoc-T Eye Drops 5 ml is used to treat open-angle glaucoma and ocular hypertension (high pressure in the eyes). It is generally used when no other medication effectively treats glaucoma or ocular hypertension. It contains Dorzolamide and Timolol, which 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. 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. Before using this medicine, you should tell your doctor if you are allergic to any of its components or if you are pregnant/breastfeeding, and about all the medications you are taking and pre-existing medical conditions
