Overview
Acute mountain sickness (AMS) affects 25–85% of unacclimatized travelers above 2,500 m (CDC Yellow Book). Acetazolamide inhibits carbonic anhydrase to accelerate acclimatization and is the CDC's most evidence-based option for AMS prevention. It's typically started 1–2 days before ascent and continued for 2 days after reaching peak elevation.
Common side effects include tingling in the hands and feet, increased urination, and altered taste of carbonated beverages. Acetazolamide is a sulfonamide derivative and should be avoided by individuals with sulfa allergies.
