How can altitude sickness be prevented?

The best way to prevent altitude sickness is to go slow — called acclimatization. This process allows your body time to adjust to the change in oxygen levels. Take your time when traveling up. For instance, spend a day at a point midway up before continuing to ascend.

You can also talk to your healthcare provider about taking acetazolamide before your trip. Taking it 24 hours before traveling to a high altitude and continuing for five days can help prevent altitude sickness. Dexamethasone can also be used preventively, but it can have serious side effects. Talk to your provider before your trip.
