About Invokana

Overview

Invokana is a prescription medicine containing canagliflozin, used alongside diet and exercise to improve blood sugar control in adults and children aged 10 years and older with type 2 diabetes. It is also used to reduce the risk of cardiovascular death, nonfatal heart attack and nonfatal stroke in adults with type 2 diabetes and established cardiovascular disease. In adults with type 2 diabetes and diabetic kidney disease with urine albumin above 300 mg/day, it is used to reduce the risk of kidney disease progression, cardiovascular death and hospitalization for heart failure. It works by blocking a protein called SGLT2 in the kidneys, allowing more sugar to leave the body in urine.

What it treats

- To improve blood sugar control alongside diet and exercise in adults and children aged 10 years and older with type 2 diabetes. - To reduce the risk of cardiovascular death, nonfatal heart attack and nonfatal stroke in adults with type 2 diabetes and established cardiovascular disease. - To reduce the risk of end-stage kidney disease, doubling of serum creatinine, cardiovascular death and hospitalisation for heart failure in adults with type 2 diabetes and diabetic kidney disease with urine albumin greater than 300 mg/day.

Safety information

Side effects

Common side effects include genital yeast infections in women, urinary tract infections and increased urination. Serious side effects that warrant prompt medical attention include ketoacidosis (a dangerous build-up of acids called ketones), loss of body fluid that can lead to sudden kidney injury, serious urinary or genital infections, allergic reactions, low blood sugar when used with insulin or medicines that increase insulin release, and bone fractures. Ketoacidosis must be assessed regardless of blood sugar levels. Invokana also carries a risk of lower limb amputation. Contact your doctor promptly if you develop an infection or ulcer on a leg or foot. Seek immediate medical attention for pain, tenderness, redness or swelling around the genitals or the area between the genitals and anus, together with fever or feeling unwell. These may be signs of Fournier’s gangrene, a serious infection that destroys tissue and requires urgent treatment.

When to call your doctor

- Seek medical help immediately for pain, tenderness, redness or swelling around your genitals or between your genitals and anus, together with fever or feeling unwell. - Contact your doctor right away if you notice an infection or an open sore on your legs or feet.

If symptoms are severe or getting worse quickly, seek emergency care rather than waiting.

Before taking this medicine

Do not take Invokana if you have had a serious allergic reaction to it, including anaphylaxis or angioedema (serious swelling). Invokana is not recommended during breastfeeding or for people with severe liver impairment. It may harm an unborn baby, especially during the second and third trimesters of pregnancy. Conditions requiring caution include: - Type 1 diabetes or other risk factors for ketoacidosis. Ketoacidosis can occur even when blood glucose is not high. Invokana should be stopped if ketoacidosis is suspected. - Risk of lower-limb amputation. Infections or ulcers on the legs or feet need monitoring and appropriate treatment. - Low body fluid levels, kidney impairment, older age or use of loop diuretics. Fluid loss can cause low blood pressure and acute kidney injury. - Urinary or genital infections, which can be serious. Pain, tenderness, redness or swelling around the genitals or the area between the genitals and anus, together with fever or feeling unwell, requires immediate medical assessment. - Use of insulin or medicines that stimulate insulin release, which increases the risk of low blood sugar. - Risk factors for bone fractures, which should be assessed before treatment. Stop Invokana if an allergic reaction occurs and seek medical attention.

Interactions

Rifampin, phenytoin, phenobarbital and ritonavir may reduce the effectiveness of Invokana. Your prescriber may need to adjust your treatment. Taking Invokana with insulin or medicines that increase insulin release, such as sulfonylureas, increases the risk of low blood sugar. Your prescriber may need to adjust these medicines. Invokana can increase digoxin levels in the body. If you take both medicines, your doctor should monitor whether your digoxin treatment needs adjusting. Invokana may lower lithium levels in the blood. Lithium levels should be checked more frequently when Invokana is started or its dose is changed. Invokana causes glucose to pass into the urine, leading to positive urine glucose tests. Urine glucose tests and the blood test called 1,5-anhydroglucitol (1,5-AG) should not be used to assess blood sugar control while taking Invokana. Your healthcare professional should use other monitoring methods.
