Acetazolamide Information (Diamox)
Acetazolamide 250mg tablets were sold under the brand name Diamox. The Diamox brand is no longer available in the United Kingdom (April 2015).

Altitude sickness is treated with Diamox tablets.
Mild altitude sickness is uncomfortable and should be taken seriously. Above 10,000 feet (3,000 metres), headache, fatigue, loss of appetite, and poor sleep are signs of early altitude sickness. Do not continue ascending until these symptoms subside.

Diamox aids in the faster resolution of early altitude sickness symptoms.

Serious altitude sickness is dangerous because it causes a buildup of fluid in the brain and/or lungs. Extreme shortness of breath and/or impaired mental function can appear suddenly. Symptoms can progress to coma and death in a matter of hours. The best treatment is a rapid descent of at least 1,500 feet (500 metres) at the first sign of these symptoms. Oxygen, steroids, and Diamox are among the other treatments available.

It’s a medical emergency if a person can’t catch their breath after everyone else has, or if they’re acting strangely or can’t walk in a straight line.

Diamox can help you sleep better.
Sleep disturbances are common at high altitudes (above 3,000 metres). There may be long gaps between breaths, followed by bursts of rapid breathing. This causes restless sleep and fatigue during the day.

Diamox can help with altitude-related sleep disturbances.

Altitude acclimatisation
Mountain sickness symptoms and dangers can be reduced with proper acclimatisation. See the acclimatisation to altitude guidelines.

Although taking Diamox reduces the risk of mountain sickness, it does not replace proper acclimatisation. Altitude sickness is still a possibility.

Diamox side effects
The majority of Diamox users experience no side effects. Extra urine, flushing, thirst, headache, dizziness, fatigue, irritability, depression, a ‘tingling’ sensation in the extremities, some loss of appetite, taste disturbance, reduced libido, and occasional drowsiness and confusion are all Diamox side effects. The Diamox Patient Information Leaflet contains a complete list of side effects.

Diamox should not be used by people who are allergic to sulpha-containing drugs.

Dose of Diamox
For early symptoms of mountain sickness, Our Doctor prescribes 250mg Diamox tablets at a dose of one twice daily. When forced ascent is unavoidable, half a tablet (125mg Diamox) twice daily is recommended.

For sleep disturbances, half a Diamox tablet (125mg Diamox) twice daily is recommended.

Online Diamox
Acetazolamide is diamox. It can be purchased from online pharmacies. Customers must, however, provide their own prescriptions to pharmacies. Private prescriptions usually cost between £20 and £45.00. Most doctors aren’t familiar enough with altitude medicine to recommend Diamox.

When buying Diamox online, specialist travel clinics charge more than My London Pharmacy.

Diamox is available in other countries.
Buying Diamox online in the UK is safer than buying it overseas.
Genuine Diamox is available from the UK registered pharmacy. Foreign tablets could be counterfeit, out of date, or of poor quality.


The Patient Information Leaflet (PIL) is a leaflet that comes with a medicine package and must be read before using it. It is written for patients and contains instructions on how to take or use medication.
