COMBIGAN EYE DROP is a combination medication containing two active ingredients, brimonidine and timolol. It is used to treat high pressure inside the eye due to glaucoma or ocular hypertension. Brimonidine works by decreasing the amount of fluid produced in the eye, while timolol works by reducing the amount of fluid in the eye. This combination helps to lower the pressure inside the eye, reducing the risk of vision loss. COMBIGAN EYE DROP is usually prescribed to be used twice a day, with a few minutes between each dose. It is important to follow the instructions provided by your healthcare provider and not to stop using the medication without consulting them first.
