Medications for Altitude Sickness

The primary medicine for Altitude Sickness is descending. Diamox is a pill for Altitude, but it isn't dependent on it. Having Diamox and continuing to go to higher places is not an intelligent idea. If you still have the problem after having Diamox, descend as soon as possible. Don't forget to drink more water after Diamox; it can make you dehydrate. Have garlic soup; it helps a bit. If you have difficulty, don't stay on the mountain for long, inform your insurance, and return to the hospital as soon as possible.

Note: If you can't sleep at Altitude, never try to use sleeping pills. Don't stay or sleep alone if you feel like you are at Altitude. Always inform your guide about your problems.
