Reviews for Diamox

MogulMonster January 17, 2013

“I don't always use medication when I go skiing in higher altitudes but when I do I prefer Diamox. This is a God send when I am sleeping at 10,000 ft and skiing at 12,000-14,000 ft. I tend to get a little clumsy and do not have the focus and sharp alertness while taking the medicine. I just need to take the medication starting a couple days before the trip for about 4-5 days. The whole process is all about getting your body acclimated to the change in altitude from sea level to 10,000 ft in a few hours. Other preparations are still needed such as avoiding alcohol, caffeine, NSAIDs, aspirin, sleeping agents. Start drinking a gallon of water each day while on this medicine.”

“Works very well to prevent symptoms of Acute Mountain Sickness with no perceived side effects. I take 125mg twice per day as recommended by the altitudemedicine.org website for high altitude hiking. This actually speeds up the bodys acclimitization process and doesn't just treat the symptoms. Highly recommend it for staying well on high altitude pursuits.”

“At age 37, I decided to take my 1st ever mountain camping trip. We found a beautiful spot at 12,497 Ft. I had been to Denver as a teenager with no reaction to altitude so I wasn’t expecting to get sick. I hydrated, but evidently not enough. Within 4 hours of making camp, I began feeling nauseous. After 6 hours, diarrhea. By 10 hours, around midnight, I was going in and out of consciousness. We thought I had severe food poisoning. Due to the dangerous location, we could not get down from the mountain. Long story short, when I returned home to Dallas Texas, I had had a mild edema. My doctor prescribed Diamox and portable oxygen for my next mountain trip. It really gets the job done. I have played around with the dosing starting at half doses &add more up to the full dose as needed. I begin Diamox 48 hours before ascending over 9.5k. I find smaller dosing decreases the drowsiness. I hope this information helps others. Be safe and well.”

“Diamox is freaking MAGIC. I used to get horrible, debilitating headaches at altitude in Breckenridge and Crested Butte. And if I had a beer, well, it was so much worse. I told my doctor, an avid skier, about it and he prescribed Diamox/acetazolamide. Game changer. Not that I condone this, but I could hang with the 20-somethings in the bar 'til closing and wake in the AM feeling great and ready to go. Since then I don't go about 8000 feet without following the protocol.”

“Anyone planning to take this medication for altitude sickness prophylaxis, I recommend you do a trial run at home first. I took this medication to hike the inca trail and started it the day before flying to Cusco. I developed a rare side effect of blurred vision/myopia which came on about an hour after the second dose of diamox. The myopia lasted for 72 hours after ceasing the medication. It almost ruined my trip but fortunately vision returned just in time to start the hike. I went on dexamethasone after that for prophylaxis. No side effects but unfortunately the Dex didn't work as I got altitude sickness.........but that's another story!”

“DO NOT if you have panic disorder. Had the worst panic attack of my life hours after taking it and thought I was gonna pass out and/or die. Guess I’ll just have to face the altitude sickness bc you couldn’t pay me ten trillion dollars to take this again. FYI I think most people do not have this experience, just warning those who have bad anxiety!”

“After several bird tours flirting with 10,000 - 11,000 ft elevation I became suspicious that I was susceptible to alt. sickness. A redirected flight to LaPaz, Bolivia (and some unscheduled ascents near Cochabamba) convinced me I was. Typically I serve as a human altimeter, within minutes of reaching 11,000 ft I'm puking my guts out. Diamox has been a wonder drug in preventing alt. sickness on tours I've been on since Bolivia. I've travelled from 8,000 ft straight to 14,000 ft several times with no alt. sickness symptoms at all. 125 mg before bed is all I need. Tingling and bad tasting soda symptoms are greatly reduced at that dosage compared to the 250mg I initially used.”

“Upon arrival in Lhasa, Tibet at approx 3000 MAS(metres above sea level) I started getting a very bad head ache. Approx 8 hrs later the headache had progressed to extreme throbbing. I drank plenty of water and took diamox as prescribed by my g.p. for altitude sickness. The next day I signed myself up on tour to travel to nam tso @ approx 5000 mas..”

“I took one of these pills (125mg) to try it before my vacation and I haven't felt so sick in a long time. OMG it was horrible!! It started with mild dizziness and tiredness. Not so bad but by the 12th hour I just wanted to check out. A lot of dizziness, very tired but couldn't sleep, nausea and headache. Generally I felt awful but couldn't put my finger on how else it made me feel this awfulness. I took a meclazine and some Advil and felt a bit better. The next day, I still felt a bit weird but not so awful. That stuff lasts a long time and if you take it on vacation and have my reaction, you'll waste a lot of hours being miserable.”

“Absolute game changer for skiing at high altitude, I thought I would inevitably spend the first few days sick and anxious from being out of breath. I did have some Dizziness and pins and needles “electric feeling”, but this side effect was worth feeling so much better and enjoying my holiday.”
