INVOKAMET® or INVOKAMET® XR can cause serious side effects, including:
- Lactic acidosis. Metformin, one of the medicines in INVOKAMET® or 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. Stop taking INVOKAMET® or INVOKAMET® XR and call your doctor right away if you have any of the following symptoms 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® or 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; are 65 years of age or older.
- Diabetic ketoacidosis (increased ketones in your blood or urine) in people with type 1 diabetes mellitus and other ketoacidosis. INVOKAMET® or INVOKAMET® XR can cause ketoacidosis that can be life-threatening and may lead to death. Ketoacidosis is a serious condition which needs to be treated in a hospital. People with type 1 diabetes have a high risk of getting ketoacidosis. People with type 2 diabetes or pancreas problems also have an increased risk of getting ketoacidosis. Ketoacidosis can also happen in people who: are sick, cannot eat or drink as usual, skip meals, are on a diet high in fat and low in carbohydrates (ketogenic diet), take less than the usual amount of insulin or miss insulin doses, drink too much alcohol, have a loss of too much fluid from the body (volume depletion), or who have surgery. Ketoacidosis can happen even if your blood sugar is less than 250 mg/dL. Your healthcare provider may ask you to periodically check ketones in your urine or blood.
- Stop taking INVOKAMET® or INVOKAMET® XR and call your healthcare provider or get medical help right away if you get any of the following. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL:
- nausea
- vomiting
- stomach-area (abdominal) pain
| - tiredness
- trouble breathing
- ketones in your urine or blood
|
- Amputations. INVOKAMET® or INVOKAMET® XR may increase your risk of lower-limb amputations. Amputations mainly involve removal of the toe or part of the foot; however, amputations involving the leg, below and above the knee, have also occurred. Some people had more than one amputation, some on both sides of the body. You may be at a higher risk of lower-limb amputation if you: have a history of amputation, have heart disease or are at risk for heart disease, have had blocked or narrowed blood vessels (usually in leg), have damage to the nerves (neuropathy) in the leg, or have had diabetic foot ulcers or sores. Call your doctor right away if you have new pain or tenderness, any sores, ulcers, or infections in your leg or foot. Your doctor may decide to stop your INVOKAMET® or INVOKAMET® XR for a while if you have any of these signs or symptoms. Talk to your doctor about proper foot care
- Dehydration. INVOKAMET® or INVOKAMET® XR can cause some people to become dehydrated (the loss of too much body water), which may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). There have been reports of sudden worsening of kidney function in people with type 2 diabetes who are taking canagliflozin, one of the medicines in INVOKAMET® or INVOKAMET® XR. You may be at higher risk if you take medicines to lower blood pressure, are on a low sodium (salt) diet, have kidney problems, or are 65 years of age or older. Talk to your doctor about ways to prevent dehydration including how much fluid you should drink on a daily basis. Call your healthcare provider right away if you reduce the amount of food or liquid you drink, for example if you cannot eat or you start to lose liquids from your body, for example from vomiting, diarrhea, or being in the sun too long
- Vaginal yeast infection. Symptoms of a vaginal yeast infection include: vaginal odor, white or yellowish discharge, or vaginal itching
- Yeast infection of the skin around the penis (balanitis or balanoposthitis). Swelling of an uncircumcised penis may develop that makes it difficult to pull back the skin around the tip of the penis. Other symptoms include: redness, itching, or swelling of the penis; rash; foul smelling discharge; or pain in the skin around penis
Talk to your doctor about what to do if you get symptoms of a yeast infection of the vagina or penis.

- have severe kidney problems, have a condition called metabolic acidosis, or are allergic to canagliflozin, metformin, or any of the ingredients in INVOKAMET® or INVOKAMET® XR. Symptoms of an allergic reaction may include: rash; raised red patches on your skin (hives); swelling of the face, lips, mouth, tongue, and throat that may cause difficulty in breathing or swallowing
Before taking INVOKAMET® or INVOKAMET® XR, tell your doctor about all of your medical conditions, including if you: have type 1 diabetes or have had diabetic ketoacidosis; have a serious infection; have a history of infection of the vagina or penis; have a history of amputation; have had blocked or narrowed blood vessels, usually in your leg; have damage to the nerves (neuropathy) in your leg; have had diabetic foot ulcers or sores; have moderate to severe kidney problems; have liver problems; have a history of urinary tract infections or problems with urination; are on a low sodium (salt) diet; have ever had an allergic reaction to INVOKAMET® or INVOKAMET® XR; are going to get an injection of dye or contrast agents for an x-ray procedure; have heart problems, including congestive heart failure; are going to have surgery (your doctor may stop your INVOKAMET® or INVOKAMET® XR before you have surgery; talk to your doctor if you are having surgery about when to stop taking and when to start it again); are eating less or there is a change in your diet; are dehydrated; have a decrease in your insulin dose; have or have had problems with your pancreas, including pancreatitis or surgery on your pancreas; drink alcohol very often or drink a lot of alcohol in the short-term; have low levels of vitamin B12 or calcium in your blood.
