Altitude Sickness

You can get altitude sickness if you’re in a place that is at a high altitude, usually more than 2,500 metres above sea level.

If you have suffered from altitude sickness before, or if you are travelling to a high altitude quickly, we may prescribe medicine to help prevent it.

We operate within a registered private pharmacy which means that we can discuss and provide any required treatments, tests or referrals as appropriate. You can also be assured that we work within a strict governance framework.

About this Medication

Preventative medications may be considered in addition to gradual ascent in moderate or high risk situations but are not a substitute for gradual ascent.

Acetezolamide is the preferred drug (unlicensed). The recommended dose is to be commenced one day prior to ascent to high altitude and then continued for at least two days after reaching the highest altitude.

About Altitude Sickness

You can get altitude sickness if you’re in a place that is at a high altitude usually more than 2,500 metres above sea level.

You’re more likely to get it if you travel or climb to a high altitude quickly.

You can get it in places like:

  • Mount Everest in Nepal
  • Mount Kilimanjaro in Tanzania
  • some places in the Alps
  • La Paz in Bolivia

Symptoms of altitude sickness usually start 6 to 10 hours after being at a high altitude.

The main symptoms include:

  • a headache
  • loss of appetite
  • feeling or being sick
  • feeling tired or exhausted
  • dizziness
  • difficulty sleeping

Sometimes, the symptoms can develop into more serious symptoms that can be life-threatening.
