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.


Invokamet is a medication made up of canagliflozin and metformin hydrochloride. It's used in combination with diet and exercise to treat type 2 diabetes in adults. 

Canagliflozin is used to decrease the risk of serious cardiovascular events in adults who have type 2 diabetes and heart disease. It's also used to decrease 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 who have albumin in the urine.

Adults with type 1 diabetes should not take Invokamet as this may increase their risk for a serious condition called diabetic ketoacidosis.

  • 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.
