Kevin, ever take Flagyl (metronidazole), the medicine prescribed for Giardia and many other general intestinal bacterial problems? That pill, no matter how fast you gulp it down, tastes AWFUL!

mweaver, the standard Diamox tablets don't have that awful taste, so I'd doubt the timed-release powder would. I'd suggest you give it a taste. Probably won't be that bad.

If it is truly bad-tasting, try mixing it with a spoon of applesauce. That works for my 6-y-o.
