About Invokana 

Invokana is considered a sodium-glucose co-transporter 2 (SGLT2) inhibitor, which controls blood sugar levels by helping the kidneys get rid of glucose from your bloodstream.

Invokana is used to treat type 2 diabetes mellitus in combination with diet and exercise. It can also help lower the risk of cardiovascular death or end-stage kidney stage in adults who have type 2 diabetes mellitus, heart disease, and/or kidney problems. Invokana is available only by prescription. It is available in a generic formulation as well as under different brand names, including canagliflozin.

Invokana may be prescribed as a tablet. It’s always important to follow the specific instructions on your prescription, as they can vary based on the formulation and dosage prescribed.

If you're prescribed Invokana, be sure to complete the full course of the diabetes medication unless your doctor specifically tells you to stop. If you don’t complete your prescription, the diabetes medication may not fully treat your type 2 diabetes mellitus.

What to avoid while taking Invokana

Invokana has 364 drug interactions. Don’t change what you take without checking with your doctor or pharmacist. That includes other medications or supplements, as well as over-the-counter drugs. When taking Invokana (canagliflozin), there are some things that you should avoid to maximize the effectiveness of the medication and minimize the risk of side effects. Here are some things to keep in mind:

  1. Dehydration: Invokana can cause increased urination, which can lead to dehydration. To help prevent dehydration, drink plenty of water and avoid excessive alcohol consumption. Drinking alcohol may increase the risk of hyperglycemia (high blood sugar) and hypoglycemia (low blood sugar), depending on how much you drink. Talk to your doctor before you drink alcohol.

  2. Low blood pressure: Invokana can cause a decrease in blood pressure, especially when taken with other medications that lower blood pressure. It is important to inform your healthcare provider about all medications you are taking to avoid potential interactions.

  3. Ketoacidosis: Invokana can increase the risk of a serious condition called ketoacidosis, which occurs when the body produces high levels of blood acids called ketones. Symptoms of ketoacidosis include nausea, vomiting, abdominal pain, confusion, and rapid breathing. If you experience any of these symptoms, seek medical attention immediately.

  4. Genital yeast infections: Invokana can increase the risk of genital yeast infections in both men and women. Symptoms of a yeast infection include itching, redness, and discharge. Practicing good hygiene and reporting any symptoms to your healthcare provider is essential.

  5. Foot ulcers and amputations: Invokana has been associated with an increased risk of foot ulcers and amputations, particularly in people with a history of these conditions. Inspecting your feet regularly and reporting any problems to your healthcare provider is crucial.
