Elevated sickness occurs if you move up in the heights, for example climbing a mountain, and the symptoms usually start at an altitude of 3000 meters or higher. It can develop into serious complications if you do not take it seriously. The disease occurs due to lack of oxygen, and can cause symptoms such as dizziness, headache and extreme fatigue. With preventive treatment and precautions you can avoid serious or troublesome symptoms of altitude sickness.1

How does acetazolamide work?

90% of the carbon dioxide of the blood is found in a chemical called bicarbonate. This usually exhales through the lungs. When you take diamox containing the active substance acetazolamide, you force your kidneys to separate bicarbonate from your body. This happens through the urine. This will result in your blood getting more acidic. When the blood gets acidic and gets a lower pH, the body compensates by increasing the oxygen production in the blood.

The increased oxygen production helps the body to acclimatize in relation to the changed oxygen content in heights. That way, treatment helps prevent and treat altitude sickness.

How to use Diamox?

Always follow your doctor’s advice when using Diamox against height sickness. The doses come in 250 mg and your doctor will usually print 1-4 a day. You should never take more than the doctor has recommended you to take. The tablets should be swallowed whole and taken with a glass of water. Your doctor may have recommended you to start treatment a few days before your planning to get up in the height.

If you forget a dose, do not compensate by taking a double dose next time. You should also not increase your dose without talking to your doctor first.
