I have been taking Micardis, 40mg. and a separate hydrochlorothiazide pill, 25mg. I was taking the HCT before the Micardis was substituted for other drugs that were causing problems. Took the combination for about a year, and suddenly my blood glucose shot up very high, after always having normal readings. My hair began to thin extremely, and my vision became blurry. I thought I had read on the Micardis package insert that diabetes was one of the possible side effects, but my dr. denies this, and I cannot find this information again. However, the side effects of HCT are listed as dehydration, dry mouth, thirst, hair loss, blurred vision, which I had all of. I stopped taking the HCT, and shortly after, the dry mouth and thirst disappeared completely. The hair loss seemed to be lessening, and hair might be growing back in again. In the meantime, dr. will not stop the Micardis because he swears it has nothing to do with the glucose levels. So I am still taking it, but worrying every day that I swallow that pill. I am writing on this board to caution you about the diuretic portion of the Micardis HCT. These symptoms sneak up on us and as for me, it took me awhile to figure out what was causing them, if I have. I prefer to take the diuretic separately from the bp drug, as it gives me more control over the dosages and necessity for them. I will go on another diuretic and see if I can avoid those problems. If anyone has information about a Micardis package insert stating that diabetes is a possible side effect, please let me know. The Micardis is very effective in lowering my bp, but since I stopped taking the HCT, the bp has been a few points higher, but still in a pretty good range. I will start Lasik, which I hope will bring the bp back down. It was running about 110/70 or thereabouts.Read More Read Less
