IMPORTANT SAFETY INFORMATION

INVOKAMET^®/INVOKAMET^® XR can cause serious side effects, including:

Lactic Acidosis. Metformin, one of the medicines in INVOKAMET^®/INVOKAMET^® XR, can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital. Call your doctor right away if you have any of the following symptoms, which could be signs of lactic acidosis: feel cold in your hands or feet; feel very weak or tired; have unusual (not normal) muscle pain; have trouble breathing; have unusual sleepiness or sleep longer than usual; have stomach pains, nausea, or vomiting; feel dizzy or lightheaded; or have a slow/irregular heartbeat

You have a higher chance of getting lactic acidosis with INVOKAMET^®/INVOKAMET^® XR if you have conditions such as: severe kidney problems, or your kidneys are affected by certain X-ray tests that use injectable dye; liver problems; drink alcohol very often (or drink a lot of alcohol in short-term); get dehydrated; have surgery; have a heart attack, severe infection, or stroke.

Do not take INVOKAMET^®/INVOKAMET^® XR if you:

Have moderate to severe kidney problems or are on dialysis, have conditions called metabolic acidosis or diabetic ketoacidosis (increased ketones in the blood or urine).

Symptoms of allergic reaction may include: rash; raised red patches on your skin (hives); swelling of the face, lips, tongue, and throat that may cause difficulty in breathing or swallowing

INVOKAMET^®/INVOKAMET^® XR may cause serious side effects, including:

Dehydration: INVOKAMET^®/INVOKAMET^® XR can cause some people to become dehydrated (the loss of too much body water).

Talk to your doctor about ways to prevent dehydration
Ketoacidosis (increased ketones in your blood or urine) has happened in people who have type 1 or type 2 diabetes, during treatment with canagliflozin. Ketoacidosis is a serious condition, which may need to be treated in a hospital. Ketoacidosis may lead to death.

Some people may also have fever, back pain, nausea, or vomiting
Low blood sugar (hypoglycemia).
