Q. A 20-year-old college athlete, male, presents at his PCP’s office in preparation for a mountain climbing trip with his friends. In particular, the group is travelling to Alaska to climb Mount Saint Elias which peaks at 18,000 feet. The patient asks his physician if there is a medication that can help him adjust to the altitude and avoid acute mountain sickness. The patient is healthy, not on any prescription medications, has no known allergies, and as a college athlete he is regularly tested for steroids or other illegal substances. The physician prescribes Diamox (acetazolamide). Which of the medication’s side effects can help alleviate acute mountain sickness?
