When you hear Invokana, a brand-name diabetes medication containing the active ingredient canagliflozin, used to lower blood sugar by making the kidneys remove glucose through urine. Also known as canagliflozin, it belongs to a class of drugs called SGLT2 inhibitors — a group designed to help people with type 2 diabetes manage their condition without relying only on insulin or metformin.
Invokana doesn’t just reduce blood sugar — it changes how your body handles glucose entirely. Instead of storing excess sugar, your kidneys push it out in your urine. That sounds simple, but it comes with real trade-offs. Studies show it can lower the risk of heart failure in some patients, but it also raises the chance of serious side effects like kidney injury, severe dehydration, and even leg amputations. The FDA added a black box warning in 2017 after data linked Invokana to doubled amputation risk in high-risk patients. If you’re taking it, you need to know your hydration levels, foot health, and kidney function better than most people do.
It’s not the only option. Other SGLT2 inhibitors like Farxiga and Jardiance work similarly but have different risk profiles. Some patients switch because of cost, side effects, or kidney concerns. Others avoid Invokana altogether if they have a history of foot ulcers, poor circulation, or chronic kidney disease. The real question isn’t whether it works — it does — but whether it’s the right tool for your body and lifestyle. The posts below cover everything from how Invokana compares to metformin and insulin, to what to do if you notice swelling in your feet, how to monitor kidney health while on it, and why some doctors now avoid prescribing it unless absolutely necessary.
