Methazolamide is used to treat glaucoma (a condition in which increased pressure in the eye can lead to gradual loss of vision). Methazolamide is in a class of medications called carbonic anhydrase inhibitors. It works by decreasing the pressure in the eye.

Methazolamide comes as a tablet to take by mouth. It is usually taken two or three times a day. Take methazolamide at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take methazolamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Methazolamide controls glaucoma but does not cure it. Continue to take methazolamide even if you feel well. Do not stop taking methazolamide without talking to your doctor.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program. It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
