Generic Name: metformin and saxagliptin (met FOR min and SAX a GLIP tin)
Brand Names: Kombiglyze XR
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 to treat type 2 diabetes.
Kombiglyze XR is not for treating type 1 diabetes.
You should not use Kombiglyze XR if you have severe kidney disease, or if you are in a state of 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 (Actoplus Met, Avandamet, Fortamet, Glucophage, Riomet) or saxagliptin (Onglyza), if you have severe kidney disease, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin).
Some people taking Kombiglyze XR develop a serious condition called lactic acidosis. This may be more likely if you have liver or kidney disease, congestive heart failure, a severe infection, if you are dehydrated, or if you drink large amounts of alcohol. Talk with your doctor about your risk.
To make sure Kombiglyze XR is safe for you, tell your doctor if you have:
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 this medicine passes 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 a Kombiglyze XR extended-release tablet. Swallow it whole.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, pale skin, irritability, dizziness, feeling shaky, or trouble concentrating. Always keep a source of sugar with you in case you have low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help you in an emergency.
If you have severe hypoglycemia and cannot eat or drink, use a glucagon injection. Your doctor can prescribe a glucagon emergency injection kit and tell you how to use it.
Check your blood sugar carefully during times of stress, travel, illness, surgery or medical emergency, vigorous exercise, or if you drink alcohol or skip meals. These things can affect your glucose levels and your dose needs may also change. Do not change your medication dose or schedule without your doctor's advice.
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.
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 Kombiglyze XR 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.
