I bought these to prepare for my hike up Mt. Whitney - starting at approx 8,300 ft and ascending to 12,000 ft the first day and then to 14,505 ft the second day. Since I live at about 500 ft. above sea level, I was intimidated by threat of Altitude Mountain Sickness (AMS). Despite that concern, I wanted to avoid Diamox - a prescription pharmaceutical drug. I am not a fan of prescription drugs and do everything I can to avoid them.
Everyone in my group began taking 2 pills twice a day, beginning 2 days before our hike, and then the morning of our hike. None of us had symptoms during the entire ascent. We met more than a few people who had to turn back due to AMS, without summiting the mountain. After reaching the summit and spending about 30 minutes there I began to get a throbbing headache so I started back down the mountain.
This will be a standard part of my preparation routine for all high altitude activities in the future. One of the ladies in our group was using Diamox, and based on her severe side effects (diuretic) I know she will avoid Diamox in the future and use this product instead.
It's difficult to know what would have happened if we hadn't taken Altitude RX. Would we have gotten sick? It's also difficult to know if the placebo effect was at work here. The fact is, I don't care. For a significant trip like ours, with time off work, travel and expenses, I viewed this as cheap insurance to make sure I could successfully summit the mountain. It was well worth the money.
