Acetazolamide is a prescription drug that blocks an enzyme called carbonic anhydrase. By doing that, it helps your kidneys get rid of extra fluid and reduces certain types of acid buildup. Doctors use it for a handful of conditions, so knowing the basics can save you time and confusion.
Most people hear about acetazolamide for altitude sickness. If you plan to trek high up in the mountains, a short course can make breathing easier and prevent headaches. The drug also treats glaucoma by lowering pressure inside the eye, and it helps some patients with epilepsy when other meds aren’t enough.
Another frequent use is in edema – when fluid pools in your legs or lungs. Because it promotes salt and water loss, acetazolamide can be part of a broader plan that includes diet changes and other diuretics. If you’ve been told you have a condition that needs to control acid levels, such as certain kidney disorders, this medication may be on the list as well.
Typical adult doses range from 125 mg to 250 mg taken once or twice daily, but your doctor will choose the exact amount based on why you need the drug. Always start with the lowest dose that works – it reduces the chance of unwanted reactions.
Most side effects are mild and go away on their own. Expect a tingling feeling in your hands or feet, a slight taste change, or more frequent trips to the bathroom. These happen because the medicine changes how your body handles acids and salts.
Serious issues are rare but worth watching for. If you develop a severe rash, feel unusually dizzy, or notice rapid heartbeat, call your doctor right away. Kidney problems or severe electrolyte imbalances can also pop up, especially if you’re also taking other diuretics.
Staying hydrated is key, but don’t overdo it. Drink enough water to keep urine light yellow, but avoid large amounts of sugary drinks that can throw off your electrolyte balance. Your doctor may ask for blood tests after a couple of weeks to check potassium and bicarbonate levels.
Women who are pregnant or planning to become pregnant should discuss acetazolamide with their healthcare provider. The drug can cross the placenta, and safety data are limited.
If you miss a dose, take it as soon as you remember – unless it’s almost time for the next one. In that case, skip the missed pill and keep your regular schedule. don’t double‑up.
Finally, store acetazolamide at room temperature, away from moisture and heat. Keep it out of reach of children, and discard any pills that are past their expiration date.
