Canagliflozin and Metformin Overview

Updated: 

Canagliflozin/metformin is a prescription medication used to treat Type 2 Diabetes.

It is a single product containing 2 different medications: canagliflozin and metformin. Canagliflozin belongs to a group of drugs called sodium-glucose co-transporter 2 (SGLT2) inhibitors. SGLT2 inhibitors work by allowing the kidneys to get rid of more sugar by dumping it in the urine. Metformin belongs to a group of drugs called biguanides. Biguanides work by reducing the amount of sugar produced by the liver. Together, these medications work to lower blood sugars. 

This medication comes in a tablet form and is usually taken twice a day with food.

Canagliflozin/metformin is also available as an extended-release tablet and is taken once daily in the morning, with a meal. Do not split, crush, dissolve, or chew the extended-release tablets. Swallow them whole. 

Common side effects of canagliflozin/metformin include diarrhea, bloating, frequent urination, and thirst.
