This thread seems to keep wandering between the indications for emergency uses of meds (injectable dex) and performance-enhancing/AMS-prevention pharmacology. While Diamox has been shown to be fairly safe in common use as a prophylaxis for AMS, the take home should be that there are "no shortcuts to the top" (as per Ed Viesturs). Fitness is key. All meds have risks and side effects and are no substitute for training. And if you're not familiar with emergency use of potent meds such as dex, then you shouldn't be concerning yourself with whether or not to carry and use them.
