I'm planning on hiking Kilimanjaro and will be in Nairobi for a while before that. Will I be able to buy the altitude sickness medication diamox there or in Kilimanjaro National Park? Can I get it over the counter?
No, you cannot get it OTC. I contacted Thomson Treks and they said that it was prescription only and could not be bought OTC. They sounds reasonable considering it is prescription only in the U.S. If you have a prescription about it, altitude sickness problems, that is another thing.
I am contacted them about alternative altitude sickness medications, and they said that you should just bring them from the U.S.
