Treatment for a metformin overdose varies. If the metformin overdose was recent, the healthcare provider may use certain medicines or place a tube into the stomach to "pump the stomach." Treatment may also involve supportive care. This type of care consists of treating the symptoms that occur as a result of the overdose. For example, supportive treatment options for a metformin overdose may include:
Dialysis
Fluids through an intravenous line (IV)
A sugar (glucose) solution to increase blood sugar
Other treatments based on complications that occur.
It is important that you seek medical attention immediately if you believe that you may have overdosed on metformin.
