Taking canagliflozin can increase the risk of having a lower limb (toe, foot, or leg) amputation. Tell your doctor if you ever had an amputation, or if you have or have ever had heart disease, peripheral vascular disease (narrowing of blood vessels in feet, legs, or arms causing numbness, pain, or coldness in that part of the body), neuropathy (nerve damage that causes tingling, numbness, and pain, usually in your hands and feet), or foot ulcers or sores. Your doctor will tell you on how to take care of your legs and feet properly to help avoid infections and complications that could lead to an amputation. Follow the doctor's instructions carefully and call your doctor right away if you have any pain, tenderness, sores, ulcers, or swollen, warm, reddened area in your leg or foot, fever or chills, or other signs and symptoms of infection.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with canagliflozin and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Canagliflozin is used along with diet and exercise, and sometimes with other medications, to lower blood sugar levels in patients with type 2 diabetes (condition in which blood sugar is too high because the body does not produce or use insulin normally). Canagliflozin is in a class of medications called sodium-glucose co-transporter 2 (SGLT2) inhibitors. It lowers blood sugar by causing the kidneys to get rid of more glucose in the urine. Canagliflozin is not used to treat type 1 diabetes (condition in which the body does not produce insulin and, therefore, cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may develop if high blood sugar is not treated).
Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
Canagliflozin comes as a tablet to take by mouth. It is usually taken once a day before breakfast or the first main meal of the day. Take canagliflozin at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take canagliflozin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor may start you on a low dose of canagliflozin and gradually increase your dose.
Canagliflozin controls type 2 diabetes but does not cure it. Continue to take canagliflozin even if you feel well. Do not stop taking canagliflozin without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Be sure to follow all exercise and dietary recommendations made by your doctor or dietitian. It is important to eat a healthful diet and exercise regularly.
Follow your doctor's instructions about drinking enough fluids throughout the day while you are on this medication.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
Canagliflozin may increase the chance of having a fracture (broken bone), particularly in the upper arms, wrists, or hands. Talk to your doctor about the risks of taking this medication.
Canagliflozin may cause other side effects. Call your doctor if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.
Keep all appointments with your doctor and the laboratory. Your doctor will order a lab test before and during your treatment with canagliflozin to check how well your kidneys are working. Your blood sugar levels should be checked regularly to determine your response to canagliflozin. Your doctor will order other lab tests, including glycosylated hemoglobin (HbA1c), to check your response to canagliflozin. Your doctor will also tell you how to check your response to this medication by measuring your blood sugar levels at home. Follow these instructions carefully.
Before having any laboratory test, tell your doctor and the laboratory personnel that you are taking canagliflozin. Because of the way this medication works, your urine may test positive for glucose.
You should always wear a diabetic identification bracelet to be sure you get proper treatment in an emergency.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
