Question: 1 / 400

Which substance is recommended for preventing acute mountain sickness?

Caffeine

Acetazolamide

Acetazolamide is a medication that is commonly used to prevent acute mountain sickness (AMS). This is because it helps to decrease the build-up of fluid in the lungs and the brain, which can occur at high altitudes. Caffeine, paracetamol, and vitamin C do not have any proven benefits in preventing AMS and may even have potential negative effects. Caffeine is a diuretic, which can increase dehydration and worsen symptoms, while paracetamol and vitamin C have not been shown to have any significant effects on AMS. Therefore, acetazolamide is the most recommended substance for preventing AMS.
