Canagliflozin is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Canagliflozin is also used by people with type 2 diabetes and heart disease to lower the risk of death from heart attack or stroke. Canagliflozin is also used by people with type 2 diabetes and kidney disease to lower the risk of dialysis, death from heart disease, and the need to go to the hospital for heart failure. Canagliflozin works by increasing the removal of sugar by your kidneys.
Read the Medication Guide provided by your pharmacist before you start taking canagliflozin and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth as directed by your doctor, usually once daily before the first meal of the day. The dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Tell your doctor if your condition does not improve or if it worsens (such as if your blood sugar remains high or increases).
See also Warning section. Frequent urination, unusual dry mouth, dizziness, and lightheadedness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if you have any serious side effects, including: signs of bladder infection (such as fever, urgent urination, burning/pain when you urinate), signs of kidney problems (such as change in the amount of urine, swelling legs/feet), signs of high level of potassium in the blood (such as muscle weakness and slow/irregular heartbeat). Get medical help right away if you have any very serious side effects, including: unusual tiredness, nausea/vomiting, stomach/abdominal pain, trouble breathing. This medication may cause a new yeast infection in the vagina or the penis. It may also cause a rare but very serious bacterial infection in the genital/anal area (Fournier's gangrene). Tell your doctor right away if you have signs of a yeast infection in the vagina (such as unusual vaginal discharge/burning/itching/odor) or in the penis (such as redness/itching/swelling of the penis, unusual discharge from the penis). However, get medical help right away if you have any pain/redness/swelling in or around the genital/anal area, along with a fever or feeling unwell. Canagliflozin does not usually cause low blood sugar (hypoglycemia). Low blood sugar may occur if this drug is prescribed with other diabetes medications, or if you do not consume enough calories from food, or if you do unusually heavy exercise. Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you don't have these reliable forms of glucose, rapidly raise your blood sugar by eating a quick source of sugar such as table sugar, honey, or candy, or drink fruit juice or non-diet soda. Tell your doctor right away about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule, and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal. Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your doctor may need to adjust your diabetes medications. This medication may cause you to lose too much body water (dehydration). This can lead to serious kidney damage. Drink plenty of fluids to prevent dehydration. Tell your doctor or pharmacist right away if you are not able to drink fluids as usual, or losing fluid (such as due to vomiting, diarrhea, or heavy sweating). Also, tell your doctor right away if you have any signs of dehydration, such as urinating less than usual, unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness/fainting. Canagliflozin may cause some bone loss, or even a broken bone. Lifestyle habits that help promote healthy bones include weight-bearing exercises, stopping smoking, limiting alcohol, and eating well-balanced meals that contain adequate calcium and vitamin D. You may also need to take calcium and vitamin D supplements. Talk to your doctor for specific advice. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

Beta-blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar, such as dizziness, hunger, or sweating, are unaffected by these drugs. Many drugs can affect your blood sugar, making it harder to control.
