Yes, acetazolamide is the generic name for the drug previously sold under the brand name Diamox.

Both versions treat the same conditions: glaucoma, altitude sickness, and certain types of seizures.

Acetazolamide can interact with several medications, including:

• Aspirin
• Lithium
• Other carbonic anhydrase inhibitors, such as topiramate
• Other diuretics

Be sure to give your provider a full list of any prescription medications and OTC supplements you're currently taking during your online visit.

Before you start acetazolamide, tell your provider if you have:

• A history of heart, liver, or kidney disease
• Diabetes
• An allergy to sulfa drugs or diuretics

Acetazolamide can cause drowsiness and confusion. Avoid driving or operating machinery until you know how it affects you.

For altitude sickness, start taking acetazolamide 24 to 48 hours before you start your ascent.

Continue taking it for at least 48 hours while you’re still at high altitude to keep your symptoms under control.

If your trip involves a fast climb to high altitudes, your clinician may prescribe acetazolamide to prevent mountain sickness.

This medication works best when you start taking it a day or two before starting your climb.

Your acetazolamide starting dose will depend on your diagnosis.

For glaucoma, it may start at 250 mg daily.

If you’re preventing altitude sickness, 500 to 1,000 mg in divided doses is common.

Be sure to take acetazolamide exactly as your clinician has prescribed. Don't adjust or stop your dosage without talking to them first.

Take your acetazolamide as soon as you remember if you miss a dose. If it's nearly time to take your next dose, skip the missed one and continue with the schedule your provider has prescribed.

Don't double up on acetazolamide to make up for a missed dose.

Call the poison control helpline at 1-800-222-1222 right away if you think you’ve taken too much acetazolamide.

Call 911 or get emergency medical help if you or someone else is showing signs of acetazolamide overdose:

• Collapse or seizure
• Difficulty breathing
• Severe drowsiness or confusion
• Electrolyte imbalances, which can show up as muscle cramps, muscle fatigue, or spasms
