Invokana is the brand name of the generic drug canagliflozin, which is used as part of a treatment plan for type 2 diabetes. When it is used in conjunction with exercise and an appropriate diet, patients may be able to better control their condition. While this drug is beneficial for many people, there are some harsh side effects that must be considered.

Before a doctor prescribes this drug to a patient, they must ensure that the benefits of taking it outweigh the risks. The doctor must also explain the potential dangers of the drug so the patient can make sure that they are willing to accept these risks and so they are able to watch for signs of adverse reactions.


A person taking this drug might have high ketones and acids in their blood, which can be life-threatening. Signs of this condition include increased urination and thirst, vomiting, nausea and trouble breathing.


Leg and foot amputations are sometimes necessary for people on this drug. Contact your doctor immediately if you have any signs that something is amiss with your leg or foot. This includes ulcers, sores, tenderness, pain or infections in the lower limbs.


A variety of infections are more likely for people on Invokana. These include yeast infections in men and women and urinary tract infections. There is also the possibility of a bacterial infection of the perineum. If you have pain, redness, swelling or tenderness of the perineum, contact your doctor. Some individuals might also feel unusually weak or tired and experience fever with this condition, which is also known as Fournier’s gangrene.

Other considerations

One possible reaction to this drug is that you might feel lightheaded or dizzy, which makes it difficult to remain ambulatory. Some patients faint. These are usually associated with dehydration, diuretic usage, low blood pressure or kidney disease. Some individuals will have hypoglycemia, hyperglycemia, nausea, vomiting, back pain, loss of appetite, fatigue, bowel changes or loss of strength.

Bone fractures and allergic reactions might also occur. Some doctors will instruct patients on how to prevent fractures. Any signs of a fracture or an allergic reaction require immediate medical attention. Hives, swelling of the face, limbs, or genitals, trouble breathing, itching and skin redness can signal an allergic reaction.

Anyone taking Invokana should alert their doctor to unusual symptoms and testing is likely to take place. In some cases, such as those that involve negligence, seeking compensation in Missouri based on the adverse reactions might be possible.
