Acetazolamide is a medicine often used to treat glaucoma but it is also frequently used to prevent Altitude Sickness. Its ability to acidify the blood increases ventilation of the lungs which in turn helps prevent altitude sickness from developing.
Acute Mountain Sickness (AMS) or altitude sickness is the name for a condition that occurs when people travel to high altitude regions without first acclimatising. Typical symptoms of mild AMS include:
Symptoms are typically worse at night. If you suffer these symptoms the only way to aid recovery is to reduce your altitude and head down off the mountain to a point where you were last comfortable. Failure to reduce your altitude could lead to severe complications like HAPE and HACE.
This medicine is for use in Adult travellers, not necessarily mountaineers, who will travel to high altitude areas quickly without suitable acclimatisation periods. Typical tourist destinations include the South American Andes (Peru and Bolivia) and Kilimanjaro treks. However, at Travelpharm we have seen it all with mountaineers off to Pakistan, Nepal and Russia.
The usual dose is half to one tablet twice daily, (125mg-250mg twice daily). This is usually started one to two days before ascent and continued daily until you have reached your highest point or are suitably acclimatised.
This medicine is being used "off-label". This means that it is not being used for its licenced indication (Glaucoma). It is however commonly prescribed for preventing altitude sickness in travellers visiting high altitudes.
Each tablet contains 250mg Acetazolamide. Also contains dicalcium phosphate, corn starch, magnesium stearate, sodium starch glycolate, povidone.
Most people tolerate Acetazolomide with few side effects reported, however, some common side effects which may effect around 1 in 10 people may include:
Acetazolamide is not suitable for everyone. The following individuals should not take Acetazolamide:
