Invokamet contains a combination of canagliflozin and metformin. Canagliflozin and metformin are oral diabetes medicines that help control blood sugar levels.

Invokamet is used with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.

Invokamet is also used to reduce the risk of cardiovascular events (including heart attack, stroke or death) in adults with type 2 diabetes and established cardiovascular disease.

Invokamet may also be used for purposes not listed in this medication guide.

How should I take Invokamet?

Invokamet is usually taken 2 times per day with meals. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Take with food.

Do not crush, chew, or break an Invokamet extended-release tablet. Swallow the tablet whole.

Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.

Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and 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, blurred vision, headache, and tiredness.

Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.

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

Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. You can easily become dehydrated while taking this medicine, which can lead to severely low blood pressure or a serious electrolyte imbalance.

If you need surgery or medical tests, tell any doctor who treats you that you are using Invokamet.

Invokamet is only part of a treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.

Store tablets in their original container at room temperature, away from moisture and heat. Do not keep Invokamet tablets in a daily pill box for longer than 30 days.
