What Metformin ER is
Metformin ER is a slow-release form of metformin, the usual first medicine for type 2 diabetes. Releasing slowly often means less stomach upset and once-a-day dosing.
What it’s for
Type 2 diabetes, especially for people who had stomach upset on regular metformin.
How it’s taken
By mouth, usually once a day with the evening meal. Swallow whole; don’t crush or chew.
Good to know
The empty tablet shell can show up in the stool; that is normal. A rare but serious risk is lactic acidosis (acid buildup in the blood), more likely with kidney disease, heavy drinking or severe illness.
