Lumigan is a medicine used to reduce pressure in the eyes in adults with glaucoma and high pressure in the eye. If the pressure in your eye is too high it can damage your sight, potentially leading to blindness. It works by helping fluid flow from inside the eye into the blood. Lumigan is suitable for adults and children and can be used by itself or in combination with other eye medicines to reduce pressure. Follow the instructions given by your doctor and use this medicine regularly to get the most benefit. If you stop using it, pressure in the eye could increase and damage your sight. Never use a bottle if the seal is broken before you use it for the first time. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back.
