Altitude Sickness

Altitude sickness is caused by travelling to a new altitude too quickly; breathing may become difficult due to the lack of oxygen at higher altitudes. It typically occurs when travelling 2,500m above sea level, and is common in mountain climbers. For this reason, it is also called acute mountain sickness, or AMS.

Medications can be taken to treat altitude sickness and are available to order from Pharmacy Online.


Altitude sickness can be treated symptomatically by taking painkillers for headaches and drinking small, regular sips of water to help with nausea and vomiting.

There are also medications available for prevention and treatment of altitude sickness. If you are planning on mountain climbing as part of your travels, ask a member of our team about the options available for prevention and treatment.


Symptoms of altitude sickness mimic those of a hangover. They often include:

  • Shortness of breath
  • Vomiting
  • Nausea
  • Headache
  • Dizziness
  • Fatigue
  • Loss of appetite
