I'm on HCTZ not so much for blood pressure, but as a diuretic to prevent migraines. I know this is weird and not supposed to work, but it works miracles. I used to have a dozen a month, and sometimes I'd throw up and pass out. Often I was delirious. On the HCTZ I have several a year.

Well, my potassium is a little low as a result of taking the drug. I think he said my last test was 3.6, which is just barely in the normal range. I take care to eat something potassium-rich every day, but it's not enough, evidently. I don't have any noticeable symptoms of low potassium (no muscle cramping), but I know there are concerns here for a myasthenic.

My doctor gave me a prescription for a supplement: 20mg a day, and I'm to have a blood test again in a week. Can one of you super-knowledgeable people help me out here? From this chart: http://www.mayoclinic.com/health/dru...ation/DR602373 it looks like 20mg isn't a high enough dose that I need to worry about overdosing, because that's what's in a potato, or a couple of small bananas. Can we talk about the concerns of low and high potassium for someone with MG, and what to look for?

Thanks!
