What is Kombiglyze XR?
Kombiglyze XR contains a combination of metformin and saxagliptin. Metformin and saxagliptin are oral diabetes medicines that help control blood sugar levels. Metformin works by decreasing glucose (sugar) production in the liver and decreasing absorption of glucose by the intestines. Saxagliptin works by regulating the levels of insulin your body produces after eating.
Kombiglyze XR is used together with diet and exercise to improve blood sugar control in adults with type 2 diabetes mellitus.
Kombiglyze XR is not for treating type 1 diabetes.
You should not use Kombiglyze XR if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment with insulin).
Some people develop lactic acidosis while taking metformin. Early symptoms may get worse over time and this condition can be fatal. Stop taking Kombiglyze XR and get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, trouble breathing, stomach pain, nausea, and feeling very weak or tired.
Before taking this medicine
You should not use Kombiglyze XR if you are allergic to metformin or saxagliptin (Onglyza), or if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment with insulin).
Some people taking metformin develop a serious condition called lactic acidosis. This may be more likely if you have liver or kidney disease, congestive heart failure, a heart attack or stroke, a severe infection, if you are 65 or older, if you are dehydrated, or if you drink a lot of alcohol. Talk with your doctor about your risk.
To make sure Kombiglyze XR is safe for you, tell your doctor if you have:
kidney disease (your kidney function may need to be checked before you take this medicine);
high triglycerides (a type of fat in the blood);
a history of alcoholism; or
if you are over 80 years old and have not recently had your kidney function checked.
If you need to have surgery or any type of x-ray or CT scan using a dye that is injected into your veins, you will need to temporarily stop taking Kombiglyze XR. Be sure your caregivers know ahead of time that you are using this medication.
Kombiglyze XR is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
It is not known whether metformin and saxagliptin pass into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Kombiglyze XR is not approved for use by anyone younger than 18 years old.
How should I take Kombiglyze XR?
Take Kombiglyze XR exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
Take Kombiglyze XR with a meal.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
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.
Your doctor may want you to stop taking Kombiglyze XR for a short time if you become ill, have a fever or infection, or if you have surgery or a medical emergency.
Blood sugar levels can be affected by stress, illness, surgery, exercise, alcohol use, or skipping meals. Ask your doctor before changing your dose or medication schedule.
Kombiglyze XR is only part of a complete program of treatment that may also include diet, exercise, weight control, blood tests, foot care, and eye care. Follow your diet, medication, and exercise routines very closely.
Store at room temperature away from moisture and heat.

-Following a switch from metformin immediate-release to metformin extended release, glycemic control should be closely monitored and dosage adjustments made according.
-When used in combination with a sulfonylurea or insulin, a lower dose of the sulfonylurea or insulin may be considered to reduce the risk of hypoglycemia.
