| That's interesting. I started metformin last July. The metformin from my pharmacy is manufactured by Caraco. With it, diet, and weight loss my blood sugar readings went from 300-400 to consistently under 100. Only problem was that I started having bad side effects and had to switch to Actos.
I would think a pharmacy dispensing diluted or impotent drugs would be in jeopardy of major trouble. I suspect it is changes in your body, you probably need to have your doctor sort it out. There are several other type 2 oral medications available in generic form. |
