Acetazolamide is used in people with certain types of glaucoma to reduce the amount of fluid in the eye, which decreases pressure inside the eye.

Acetazolamide is also used as a diuretic ("water pill") in people with congestive heart failure, to reduce the build-up of fluid in the body. This build-up is called edema.

Acetazolamide is also used to treat certain types of seizures, and to treat or prevent altitude sickness.

Phenytoin is an anti-epileptic drug, also called an anticonvulsant. Phenytoin works by slowing down impulses in the brain that cause seizures.

Phenytoin is used to control seizures. It does not treat all types of seizures, and your doctor will determine if it is the right medicine for you.
