Our guides will be carrying “Diamox “, a medicine that does not cure altitude sickness but helps prevent it.
If you feel like you will develop a symptom of altitude sickness, you are supposed to take it before you start the trek, not after they symptom develops. If you are doing a high altitude trek, you had better check with your physician before you leave the country, if you have heart and breathing problem or not and if diamox would have any adverse effect on you. Besides, taking plenty of hot water, keeping onself relaxed, not consuming alcohol and walking slowly and taking enough rest will help to avoid altitude sickness.
