Keep the Different Meds Used for Altitude Sickness Straight
Ski trips and mountain treks can be ruined when thin air causes altitude sickness...headache, nausea, fatigue, etc.
Nondrug options should be tried first as prevention for many patients. These include ascending gradually, staying hydrated, limiting alcohol, and avoiding overexertion for the first 48 hours at high altitudes.
Acetazolamide (Diamox, etc) can be used to prevent altitude illness for some higher-risk patients...such as those ascending over about 3,500 metres in one day.
