What is the dosage of Diamox required to prevent High Altitude Sickness?
I’m going to Tibet in a June for 5 days and had went to a GP to get Diamox to combat HAS (high altitude sickness). She gave me 7 pills x 250mg of Diamox (1 pill a day, start eating 2 days before arrival in Tibet). I’m worried that the dosage may not be enough as I read that you need 500mg of Diamox a day to combat HAS. I’m a healthy 22 yo female with a normal-slightly above average weight with no known illness or allergies. Should I ask for more Diamox?
Thank you for your question.
From your research on the internet, it would certainly seem reasonable to discuss this further with your GP. Perhaps they will have information that supports their prescription and it might be worth deciding together what is best.
In terms of altitude sickness, the general advice is that you ascend slowly to limit the development of HAS. There are numerous international guidelines on ways to prevent it and in general the advice is to limit climbing to <500m per day.
It is also worth discussing with your guides as to what they have planned for you and if you are uncertain about your fitness, taking things easier might be best.
Good luck with your trip and have a great time!
