Read the Medication Guide provided by your pharmacist before you start taking this medication 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 with the morning meal. Swallow the tablets whole. Do not crush or chew the tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day. Drink plenty of fluids while taking this medication unless otherwise directed by your doctor.

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). To reduce your risk of side effects (such as upset stomach), your doctor may direct you to start this medication at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.

Tell your doctor if your condition does not get better or if it gets worse (your blood sugar is too high or too low).

See also Warning section.

Nausea, vomiting, stomach upset, diarrhea, bloating/gas, frequent urination, unusual dry mouth, or weakness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. If stomach symptoms return later (after taking the same dose for several days or weeks), tell your doctor right away. Stomach symptoms that occur after the first days of your treatment may be signs of lactic acidosis.

An empty tablet shell may appear in your stool. This effect is harmless because your body has already absorbed the medication.

Remember that this medication has been prescribed because your doctor 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 a urinary tract infection (such as burning/painful/frequent/urgent urination, pink/bloody urine), 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).

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.

This medication 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 increased thirst/urination. If these symptoms occur, tell your doctor right away. Your doctor may need to adjust your diabetes medication, exercise program, or diet.

Canagliflozin may rarely increase the risk of losing a lower limb. This risk may be greater in people who have a history of heart disease, blood circulation disease (peripheral vascular disease), nerve problems (neuropathy), foot ulcers, or previous loss of limbs. Talk to your doctor for more details. Tell your doctor right away if you have any pain/tenderness/redness/swelling/sores on your legs and feet.

This medication may cause you to become dehydrated. 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. To reduce the risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.

Canagliflozin may cause bone loss (osteoporosis), or even a broken bone. Lifestyle changes that help promote healthy bones include increasing weight-bearing exercise, 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. Consult 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 not affected by these drugs.

Limit alcohol while using this medication because it can increase your risk of developing lactic acidosis, low blood sugar, or a high ketone level.

High fever, "water pills" (diuretics such as hydrochlorothiazide), too much sweating, diarrhea, or vomiting may cause dehydration and increase your risk of lactic acidosis. Stop taking this medication and tell your doctor right away if you have prolonged diarrhea or vomiting.

Consult your doctor because this may require a change in your treatment plan, medications, or blood sugar or ketone testing.

Older adults may be at greater risk for side effects such as low blood sugar, dehydration, lactic acidosis, dizziness/fainting (usually when standing), or bone loss while using this drug.
