What is a Generic Drug?
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

Product Details
Description
Invokamet is made up of two medications, canagliflozin and metformin hydrochloride. It's used with diet and exercise to treat adults with type 2 diabetes. Canagliflozin is used to decrease the risk of serious cardiovascular events in adults with type 2 diabetes and heart disease and the risk of end-stage kidney disease, doubling serum creatinine levels, death caused by cardiovascular reasons, and hospitalization for adults with type 2 diabetes, heart failure, and diabetic kidney disease with the presence of albumin in the urine.
Invokamet should not be used to treat adults with type 1 diabetes as this may increase their risk for a serious condition called diabetic ketoacidosis.

Cautions
WARNING: LACTIC ACIDOSIS
See full prescribing information for complete boxed warning.
- Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. Symptoms included malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Laboratory abnormalities included elevated blood lactate levels, anion gap acidosis, increased lactate/pyruvate ratio; and metformin plasma levels generally greater than 5 mcg/mL.
- Risk factors include renal impairment, concomitant use of certain drugs, age greater than 65 years old, radiological studies with contrast, surgery and other procedures, hypoxic states, excessive alcohol intake, and hepatic impairment. Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the Full Prescribing Information.
- If lactic acidosis is suspected, discontinue INVOKAMET/INVOKAMET XR and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended.
