We recommend that our climbers use a medication called Diamox to help them acclimatize, as it increases your oxygen saturation, a key element in the acclimatization process. You should start taking it 2 days before your climb and stop after you reach the highest elevation on the trek. We advise you to test it for 2 days prior to the start of your climb to determine if you have any adverse reaction to it.
It’s not a magic bullet and will not cure AMS, but can help speed up acclimatization for sure. In our long experience on Kilimanjaro we’ve seen it work extremely well. Diarrhea and stomach cramps can sometimes occur when using Diamox. Uncommon side effects include nausea and headache. If this happens, stop taking the drug. Common minor side effects include numbness, tingling sensations in hands, feet, and lips, taste alterations and ringing in the ears. These you can live with, and go away when the medicine is stopped.
Also, since Diamox works by forcing a bicarbonate diuresis, you urinate more while using this medication, which means you should increase your water intake. Talk with your doctor as it requires a prescription.Meet Tusker's medically trained expert guides
