How should I take canagliflozin and metformin?

Your doctor may prescribe a glucagon injection kit in case you have severe hypoglycemia. Be sure your family or close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination.

Your doctor may have you take extra vitamin B12. Take only the amount of vitamin B12 that your doctor has prescribed.
