Diabetic ketoacidosis: If blood sugar levels are too high (hyperglycemia), a condition known as diabetic ketoacidosis may occur. In this condition, your body starts to use body fat as fuel, eventually leading to a large concentration of acid in the blood stream. This can result in unconsciousness, coma or death. Your risk of developing diabetic ketoacidosis may be increased if you are on a low carbohydrate diet, drink a lot of alcohol, have a severe illness or infection, or have problems with your pancreas. There have been reports of diabetic ketoacidosis in people taking Invokana (Canagliflozin).

Dizziness: Some people taking Invokana (Canagliflozin) may experience decreases in blood pressure. This occurs because the medication causes an increased amount of fluid, along with the glucose, to be removed from the body through the kidneys. These blood pressure drops could lead to dizziness, lightheadedness, and falls. This may occur when you shift your body position, such as rising from a sitting or lying position. If you experience this problem, try getting up more slowly. If it persists or if you faint, contact your doctor. Seniors and other individuals who are at risk of experiencing Low Blood Pressure (e.g., dehydration, taking medications for high blood pressure) should discuss with their doctor how Invokana (Canagliflozin) may affect their medical condition, how their medical condition may affect the dosing and effectiveness of Invokana (Canagliflozin), and whether any special monitoring is needed.

Glucose control: When Invokana (Canagliflozin) is taken along with other medications for diabetes, glucose levels may drop too far, causing confusion, cold sweats, cool and pale skin, headache, fast heartbeat, or weakness.
