What is Invokana?

Invokana (generic name Canagliflozin) is a diabetes medicine that is used along with diet and exercise to help keep blood sugar levels under control. If you have type 2 diabetes and also suffer from heart disease, then Invokana can save your life by lowering your chances of having a heart attack or stroke.

In people with type 2 diabetes and diabetic kidney problems where there is some protein in the urine, Invokana can lower the risk of worsening kidney function and kidney failure. It can also lessen your chances of dying from a heart attack or stroke. It can lower your chances of being hospitalized for heart failure (a problem where the heart becomes weak and cannot pump enough blood around the body). By preventing heart failure, Invokana can keep you out of the hospital.

What is Invokana used for?

Invokana is used by adults with type 2 diabetes to help lower blood sugar along with diet and exercise. It's also used by adults with type 2 diabetes who have a risk of heart disease, to help prevent heart attacks, strokes, and sudden death. It's used by adults with type 2 diabetes and diabetic kidney problems to prevent worsening kidney disease, heart failure, and death from heart disease.

Invokana should only be used by people over age 18 with type 2 diabetes. It is not for people with type 1 diabetes. It should not be used if you have diabetic ketoacidosis (a condition where there is too much acid in your blood). Diabetic ketoacidosis happens when your blood sugar is too high for too long.

Do not use Invokana if you're pregnant, planning to become pregnant, or are breastfeeding or planning to breastfeed. Invokana is not for people with severe kidney problems, or those on dialysis. Tell your doctor if you have kidney, pancreas or liver problems before taking Invokana. Avoid drinking alcohol while using Invokana. Talk to your doctor if you're changing your diet or starting to eat less before using Invokana. If you're planning to have surgery, let your doctor know before starting Invokana.

Before starting Invokana, talk to your doctor if you have any of the following:

  • a history of amputation, or have blocked or narrowed blood vessels (in your legs, or any other parts of your body)

  • diabetic foot ulcers or sores

  • numbness tingling or nerve damage in your leg

  • a history of trouble with peeing (urination) or urinary tract infections (UTI)

  • currently eating a low-salt diet

  • using or planning to use any other prescription or over-the-counter medicines, including vitamins (especially drugs like digoxin, rifampin, ritonavir, phenytoin, phenobarbital, or water pills / diuretics)

How does Invokana work?

Invokana works by helping your kidneys remove sugar from your body. Your kidneys most important job is to filter blood. Invokana tells your kidneys to pee out any extra sugar.

What are possible Invokana side effects?

The most common Invokana side effects include:

  • Changes in how you pee
    • Invokana can increase how much you pee, so you may need to pee more often, or at night.
  • Genital yeast infection (vaginal infection in women and penis infection in men)
    • It can cause pain, odor, redness, itching, swelling, or discharge from the vagina or penis

Rare, but serious Invokana side effects include:

  • Amputations (surgery to remove a toe, foot, or leg)
    • If you have any new pain, soreness,ulcers, or infections in your leg or foot, call your doctor right away. You're at a higher risk of amputation if you have heart disease, nerve damage in your legs, blocked or narrow blood vessels in your legs, a history of diabetic foot ulcers, or a history of amputation.
  • Dehydration and low blood pressure
    • You can feel faint, lightheaded or dizzy, especially if you try to stand up too fast. This is more likely to happen if you're older (over age 65), take blood pressure medicine, have kidney problems, or eat a low salt diet.
  • Urinary tract infection (UTI)

    If you have a UTI, you may experience any of the following symptoms:

    • Feeling pain or burning when you pee
    • Feeling like you cannot control your pee because you need to pee more frequently or urgently
    • Pain in your pelvis
    • Fever or back ache
    • Nausea (feeling sick to your stomach)
    • Throwing up

    Call your doctor right away if you feel like you may have a UTI. A possible Invokana side effect is a very serious UTI which requires going to the hospital, so it's best to let your doctor know immediately if you begin having any symptoms.

  • Low blood sugar
    • This can leave you feeling shaky, sweaty, tired, weak, hungry, confused and irritable, feeling like your heart is racing, or give you a headache. Be sure to talk to your doctor before starting Invokana to check your risk for developing low blood sugar (especially if you take Invokana with other diabetes medicine). Understand how to bring your sugar back up safely, as directed by your doctor.
  • Kidney problems
    • A possible Invokana side effect is that it may harm your kidneys. Be sure to have routine blood tests before and while using Invokana to make sure your kidneys stay healthy. Call your doctor right away if you suddenly start to eat or drink less (for example, if you get sick), or if you start losing fluid (through diarrhea, vomiting, or blood loss) because this can make it more likely for Invokana to hurt your kidneys.
  • Increased ketones in blood and urine (ketoacidosis)
    • You may feel sick to your stomach, or throw up. Some people feel tired, have stomach pain, or have trouble breathing. This can happen even if your blood sugar is less than 250mg/dL, so be sure to check for ketones in your urine if you experience any of these symptoms.
  • Allergic reaction (rash, hives, swelling of face and tongue, trouble breathing)
  • A severe genital infection around the anus
    • Sometimes Invokana can harm the tissue under the skin around the anus, and cause pain, redness and swelling in your genital area.
  • Fractures or broken bones
    • Some people who take Invokana are more likely to develop fractures, so talk to your doctor, especially if you are at risk for osteoporosis (thinning bones)

  • How long does Invokana stay in your system?

    The length of time Invokana stays in your system varies depending on how well your kidneys work and the dose of Invokana. In most adults with healthy kidneys (normal kidney function), Invokana will stay in your body for about 3 days after the last dose.

  • Why does Invokana cause amputations?

    Invokana is associated with a higher risk of amputations. It is not known why some people who take Invokana are more likely to need an amputation. Some experts believe that Invokana hurts the circulation in your legs because it increases the amount of liquid you pee. If there is poor circulation in your legs, you're more likely to get foot ulcers or infections in your legs. There are no studies yet that prove this idea.

  • How much does Invokana cost?

    Prescription Invokana cost can change depending on the dose and how it is prescribed. If Invokana cost is a concern, speak to your doctor. Patients may choose to buy Invokana online from to help manage high costs.
