Metformin can cause nausea, vomiting and diarrhea. Sometimes it can lead to a more serious condition known as lactic acidosis, characterized by consistent and severe stomach upset and dizziness. Although it does not cause hypoglycemia on its own, when paired with other anti-diabetic medications, low blood sugar can result.
WebMD recommends that metformin be taken orally with water one to three times per day depending on the doctor's prescription.
