Uses

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.

How To Use

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).

Side Effects

Frequent urination, unusual dry mouth, dizziness, and lightheadedness may occur. If any of these effects last or get worse, 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 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 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 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.

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

• kidney disease
• disease of the pancreas (pancreatitis)
• dehydration
• use/abuse of alcohol
• low blood pressure
• heart failure
• mineral imbalances (such as high levels of potassium)

You may experience blurred vision, dizziness, or drowsiness due to extremely low or high blood sugar. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely.

Limit alcohol while taking this medication because it can increase your risk of developing low blood sugar and a high ketone level.

It may be harder to control your blood sugar when your body is stressed (such as due to fever, infection, injury, or surgery). Also, if you are eating less or not able to eat due to these conditions or any illness, this can lead to a high ketone level while you are taking this medication. Consult your doctor because this may require a change in your treatment plan, medications, or blood sugar or ketone testing.

Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Older adults may be more sensitive to the side effects of this drug, especially dizziness/fainting (usually when standing), dehydration, or some bone loss.

During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.

Pregnancy may cause or worsen diabetes. Discuss a plan with your doctor for managing your blood sugar while pregnant. Your doctor may change your diabetes treatment during your pregnancy (such as diet and medications including insulin).

Drug Interactions

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

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. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar. Check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high or low blood sugar. (See also Side Effects section.) Your doctor may need to adjust your diabetes medication, exercise program, or diet.

This medication may interfere with certain lab tests (such as urine glucose test), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.

Overdose
