Lumigan 0.01% Ophthalmic Solution 3 ml is used to treat raised/increased pressure in the eye in patients suffering from open-angle glaucoma or ocular hypertension. It contains Bimatoprost, which works by increasing the production of aqueous humour (fluid in the eye) and reducing eye pressure. In some cases, it may cause certain side effects, such as eye itching and conjunctival hyperemia (inflammation in the eye). 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.
