Altitude sickness, or acute mountain sickness (AMS), can occur if a person travels to a high altitude too quickly. At over 3,000m above sea-level it isn’t possible to take in as much oxygen which makes breathing difficult and between 6 and 24 hours after reaching that height, altitude symptoms may develop. Acetazolamide is an altitude medication which effectively treats and prevents the symptoms of elevation sickness, such as: shortness of breath, loss of appetite, tiredness, dizziness, nausea and vomiting and headache. By taking Acetazolamide medicine 1-2 days before the trip and whilst going up in altitude, these symptoms should be minimal.
