What Is Acetazolamide and How Does It Work?

Acetazolamide is a sulfonamide-derivative carbonic anhydrase inhibitor. Depending on where it acts in the body, it can reduce fluid pressure in the eye (used for certain glaucomas), increase fluid and salt elimination through the kidneys (used as an add-on treatment for edema from congestive heart failure or from other drugs), help control certain seizure types as an adjunct to other seizure medicines, and reduce the fluid shifts that contribute to acute mountain sickness symptoms in people ascending to high altitude. It's taken by mouth as an immediate-release tablet, generally on a schedule your prescriber sets for your specific condition.

Why Prices Vary and How to Save

Acetazolamide is sold only as a generic; the older brand, Diamox, is no longer marketed in the U.S. Because it's a widely produced generic, cash prices can differ significantly by pharmacy, so it's worth comparing before you fill. Rx.com compares prices at more than 60,000 pharmacies to help you find a lower price near you, regardless of whether you have insurance.

Alternatives and Related Medications

For eye pressure, other options your provider may consider include methazolamide, an oral carbonic anhydrase inhibitor, or dorzolamide, a carbonic anhydrase inhibitor delivered as eye drops rather than a pill. For fluid retention, other classes of diuretics such as furosemide are sometimes used instead, though they work differently. Which option makes sense depends on your specific diagnosis, so this isn't a substitute for your prescriber's guidance.

Safety Information

Acetazolamide shouldn't be used by people with a sulfonamide allergy, low sodium or potassium levels, adrenal gland failure, severe kidney or liver disease, or certain types of acidosis, and it isn't meant for long-term use in some chronic angle-closure glaucoma. Taking high-dose aspirin together with acetazolamide has been associated with serious reactions including severe acidosis, so tell your provider about all medications you take, including aspirin. Common side effects can include tingling in the fingers/toes, taste changes, and increased urination. This is general information, not medical advice — talk with your provider about whether acetazolamide is right for you.
