It is also possible that metformin may cause hair loss indirectly. Taking metformin long-term may increase the risk of vitamin B-12 deficiency, which can sometimes cause hair loss. However, it is also possible that hair loss in people taking metformin is a result of their health condition rather than the medication.

In rare cases, metformin can cause lactic acidosis, a serious side effect. Lactic acidosis is the harmful buildup of lactic acid in the blood. It can lead to low blood pressure, a rapid heart rate, and even death. Vomiting and dehydration increase the risk of lactic acidosis in people taking metformin.
