What is Acetazolamide?

Acetazolamide is a prescribed drug that is used for the prevention of altitude sickness. It should not be used as an alternative to the preparation for ascending high altitudes or acclimatisation.

How does Acetazolamide work?

Acetazolamide is a carbonic anhydrase inhibitor and diuretic. It works by affecting the acidity of the blood which reduces the probability of symptoms such as headaches. It produces bicarbonate, which assists in the process of removing the right amounts of water from the blood by urinating. It lowers the level of fluids around the heart, brain, and lungs to aid breathing. With this effect, the drug helps prevent the symptoms of altitude sickness from happening. The active ingredient is also used in treating glaucoma.

How to take Acetazolamide

Each of the 250mg tablets must be swallowed whole with a full glass of water while eating a meal. The prescribed dose depends on the individual needs but most likely up to 4 tablets taken in a day. It is usually advised as a preventive treatment that should begin one or 2 days before beginning to ascend. Follow the prescribed treatment by the doctor. Do not increase or decrease the dosage without consulting your doctor.


Acetazolamide tablets are only manufactured in the form of 250mg tablets. The dosage is specifically formulated to maximise the efficiency of the drug and minimising the possibility of adverse effects.

There are minimal side effects and may rarely occur. These are vomiting, nausea, dizziness, and rashes. Side effects may happen but very mild and not for long. More serious side effects like allergic reactions need medical attention.
