I started on 2,000 mg metformin and had great results but the gastric side effects were troubling enough that I switched to metformin ER. That helped with the gastro-intestinal, resolved it enough that I can live with it. The up side: zero risk of constipation.
My numbers have been about 10 points higher on the ER - fastings in the 90's/low100's vs 80's/90's - and daytime readings from high 90's-115 vs mostly keeping them <100. Dr. Bernstein recommends using the brand vs generic, but insurance won't pay and I can't afford.
So - I'm stuck w/ varying generic brands and the most prevalent seem to be Teva and Sun Pharmaceuticals. CVS gave me Teva last month in NC, but now in CA they refilled with generic from Sun Pharmaceuticals.
Jenny talked about generics on her blog Diabetes Update: Differing Brands of Generic Metformin Behave Differently and it got me a little concerned about starting my current refill. Am not in the mood for more issues or less efficacy.
Any of you have issues with differing generic brands/mfgs? Often the drug company/brand is on the label somewhere.
