What is canagliflozin?
Canagliflozin is an oral diabetes medicine that helps control blood sugar levels. Canagliflozin works by helping the kidneys get rid of glucose from your bloodstream.
Canagliflozin may also be used for purposes not listed in this medication guide.
You should not use canagliflozin if you have severe kidney disease or if you are on dialysis. Canagliflozin is not for treating type 1 diabetes.
Before taking this medicine
You should not use canagliflozin if you are allergic to it, or if you have:
severe kidney disease (or if you are on dialysis).
To make sure canagliflozin is safe for you, tell your doctor if you have ever had:
bladder infections or other urination problems;
blood circulation problems;
nerve problems caused by diabetes;
a diabetic foot ulcer or amputation;
an electrolyte imbalance (such as high levels of potassium in your blood);
high cholesterol levels;
if you are on a low salt diet; or
if you use insulin or other oral diabetes medicines.

How should I take canagliflozin?
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Canagliflozin is usually taken once per day, before the first meal of the day.
You may have very low blood pressure while taking this medicine. Call your doctor if you are sick with vomiting or diarrhea, or if you are sweating more than usual. Drink plenty of liquids while you are taking canagliflozin.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, fast heart rate, and feeling anxious or shaky. To quickly treat low blood sugar, always keep a fast-acting source of sugar with you such as fruit juice, hard candy, crackers, raisins, or non-diet soda.
Your doctor can prescribe a glucagon emergency injection kit to use in case you have severe hypoglycemia and cannot eat or drink. Be sure your family and close friends know how to give you this injection in an emergency.
Also watch for signs of high blood sugar (hyperglycemia) such as increased thirst or urination, blurred vision, headache, and tiredness.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your insulin dose or schedule.
Canagliflozin is only part of a complete treatment program that may also include diet, exercise, weight control, regular blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Canagliflozin can cause positive results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using canagliflozin.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while taking canagliflozin?
Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.
