Although my doctor was on the metformin bandwagon a while ago, I noticed at the hosptial that the metformin perspcriptions were plummeting.
One thing about healthcare: they dont say much when prescribing standards change.
For example, when the recommendations for ibuprofen dropped from 2 pills a does to one and none when bone healing needs to occur, that didnt receive a lot of press.
same thing happened to the statins about 6 years ago
