My Kaiser people recommended I take Mafloquine 250 mg which I had used for other trips. And thanks for reminding me; I take the last pill tomorrow. I think they were more concerned about the Bangladesh-India (Sikkim) portion of the trip than Bhutan.

Did not do the altitude pills on this trip. And while I was a bit short of breath on some of the hikes, not a big deal. I did use Diamox several years ago when in Tibet and would recommend if you get there, use the meds!

You can always check with your tour people!
