How long does Metformin ER stay in your body?

A single dose of metformin ER has the capability to regulate your blood sugar levels for approximately 12 hours. However, should you cease taking the medication, it typically requires around 4 days for the majority of it to be expelled from your body. This duration is largely calculated from the half-life of metformin ER and may vary based on individual health factors and genetic makeup, meaning the exact time frame could differ from person to person.
