Doreye Eye Drop is a medicine used to reduce pressure in the eyes. This pressure can be caused by or lead to an illness called glaucoma. If the pressure in your eye is too high it can damage your sight. Doreye Eye Drop works by decreasing the amount of fluid inside the eye. Never use Doreye Eye Drop if the seal is broken before you use it for the first time. Wash your hands before using it and shake the bottle well before each use. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back. Do not stop using this medicine without asking your doctor. Otherwise, the pressure in your eye will not be controlled and this could damage your sight. The most common side effects of Doreye Eye Drop are stinging and burning sensation, blurred vision, and bitter taste in your mouth. Sometimes people experience more general effects such as headache, nausea, tiredness, or eye irritation. If your vision is blurred or you have other changes in sight for a time, do not drive until your vision is clear. Do not use this medicine if you have severe kidney problems or are allergic to medicines called sulphonamides. Talk to your doctor before taking it if you have liver problems, dry eyes, or cornea problems. Do not use other eye medications unless your doctor tells you to.
