Glucomol 0.5% Eye Drop treats ocular hypertension and glaucoma. Glucomol 0.5% Eye Drop belongs to a class of medications known as beta blockers. It is used to lower eye pressure (ocular hypertension). This pressure can cause glaucoma. If the pressure in your eye is too high, it can harm your vision. This medication works by allowing fluid to move from within the eye into the bloodstream. It can be used alone or alongside other eye drops. Avoid using it too frequently, as this can reduce its effectiveness. You should only use it in the afflicted eye and take it as directed by your doctor. Most persons who have glaucoma or high pressure in their eyes do not feel ill. If you quit using it, your eye pressure will not be managed. This could result in the loss of sight.
