About this product
Acetazolamide works differently to travel sickness tablets. It helps your body adjust to altitude by changing how your kidneys handle bicarbonate. This supports your breathing pattern and can help your body acclimatise more smoothly.
It’s not suitable for everyone. A clinician will check your medical history, other medicines, and your travel plans before supplying it. They’ll also explain possible side effects and how to take it safely.
How to use
Half a tablet (125mg) twice daily. This should be started two days before ascent over 2500m and then continued twice daily until you have reached your highest altitude or you are suitably acclimatised.
This medicine is being used "off-label". This means that it is not being used for its licenced indication. It is however the most commonly prescribed medicine for preventing acute mountain sickness in travellers visiting high altitudes.
