Altitude sickness in practice

It strikes when the body climbs too fast, usually above about 3,000 m. Headache, nausea, poor sleep and dizziness are the common signs. The best remedy is acclimatisation: walk slowly ("pole pole" in Swahili), drink plenty and choose a longer route; see Machame or Lemosho. If symptoms worsen, the guide decides on descent: follow him or her.

Diamox: what the sources say

The sources we read agree on one thing: Diamox can help prevent altitude sickness but does not replace acclimatisation. They differ on dose and timing. We therefore give no dosage: see a doctor or a travel clinic about a month ahead, especially with a sulfa allergy or pregnancy.

Completing your preparation

Also plan vaccines and malaria with the Tanzania health page and the budget with the cost of a climb.

FAQ

How much water should I carry?

The crew supplies water to purify; bring bottles and a purification method approved by your agency.
