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. Proper control of diabetes may also lessen your risk of a heart attack or stroke. 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 and response to treatment.
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 levels remain high or increase).
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 high level of potassium in the blood (such as muscle weakness and slow/irregular heartbeat).
Use of this medication may result in a new yeast infection in the vagina or penis. You are more likely to get a yeast infection from canagliflozin if you had yeast infections in the genital area before. Uncircumcised men are also at an increased risk for infections. Tell your doctor right away if you have signs of 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). Your doctor may direct you to use nonprescription antifungal products to treat these infections. Tell your doctor if your condition persists or worsens after treatment.
Canagliflozin does not usually cause low blood sugar (hypoglycemia). Low blood sugar may occur if this drug is prescribed with other anti-diabetic 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 anti-diabetic medications.
Canagliflozin may cause you to lose too much body water (dehydration). You may be at an increased risk for dehydration if you have persistent vomiting/diarrhea or are taking certain drugs (such as diuretics/"water pills"). Contact your doctor right away if you notice any symptoms of dehydration, such as unusual decreased urination, unusual dry mouth/thirst, fast heartbeat, or dizziness/lightheadedness/fainting. Your doctor may direct you to drink more fluids to avoid dehydration.
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.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Other medications can affect the removal of canagliflozin from your body, which may affect how canagliflozin works. Examples include rifamycins (such as rifampin, rifabutin), drugs used to treat seizures (such as phenobarbital, phenytoin), ritonavir, among others.
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 level 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 levels, making it more difficult to control your blood sugar.
