Invokana may increase your risk of needing a lower limb amputation. This was rare in studies, though.

“Lower limb amputation is the removal of a leg, foot, or toe. If you have a wound that doesn’t heal or an infection that doesn’t get better with medication, this may be needed.”

If you have diabetes, which Invokana is used to treat, you have a higher risk of lower limb infections and amputation. This is because diabetes can damage your blood vessels and lead to poor blood flow in your lower legs and feet. This makes it harder for your body to heal wounds and infections, and they can become serious.

Diabetes can cause damage to your nerves and cause a reduced feeling in your legs and feet. You may not notice injuries until they become more severe.

With Invokana, genital yeast infections are more common in females* than in males.* They’re also more common in people who’ve had past genital yeast infections, and in males who haven’t been circumcised.

* In this article, we use the terms “male” and “female” to refer to someone’s sex assigned at birth. For information about the difference between sex and gender, see this article.

“Fournier’s gangrene.”

In studies, “Fournier’s gangrene.” was reported rarely with Invokana.

Invokana can help manage blood sugar levels by helping your body get rid of excess sugar.

By removing sodium and water from your blood, Invokana can reduce strain on your heart, blood vessels, and kidneys. This, along with well-managed blood sugar, lowers the risk of certain cardiovascular complications of diabetes. These include A heart attack., heart failure, and stroke. Invokana also helps prevent worsening kidney function in people with diabetic nephropathy.

Is Invokana used for weight loss?

Invokana is not used for weight loss. Some people taking Invokana lose weight. The medication helps your body excrete excess sugar through urine. Your body stores sugar as fat.

For helping to manage blood sugar levels, Invokana is prescribed with a balanced diet and exercise. This can also lead to weight loss during Invokana treatment.

Does Invokana cause hair loss, pancreatitis, or joint pain?

No, this isn’t likely. Hair loss and joint pain weren’t reported in studies of Invokana.

Pancreatitis (inflammation of the pancreas) was rarely reported in studies. But this side effect also occurred at a similar rate in people who took a placebo.* So it’s unlikely that Invokana caused pancreatitis in these studies.

Joint pain or pancreatitis can be a side effect of certain other diabetes drugs. The Food and Drug Administration issued a warning about joint pain occurring with a group of diabetes drugs called dipeptidyl peptidase-4 (DPP-4) inhibitors. These drugs can also cause pancreatitis.

But Invokana doesn’t belong to this group of medications. Instead, it belongs to a group of drugs called SLGT2 inhibitors.

If you are concerned about your risk of hair loss, you should talk to your doctor.

A placebo is a treatment that does not have an active drug.
