What is Metaglip?
Metaglip is a combination of two oral diabetes medicines that help control blood sugar levels.
Metaglip may also be used for purposes not listed in this medication guide.
You should not use Metaglip if you have severe kidney disease or diabetic ketoacidosis (call your doctor for treatment).
You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. Call your doctor or get emergency medical help if you have unusual muscle pain, trouble breathing, stomach pain, dizziness, feeling cold, or feeling very weak or tired.
Before taking this medicine
You should not use Metaglip if you are allergic to glipizide or metformin, or if you have:
severe kidney disease; or
metabolic acidosis or diabetic ketoacidosis (call your doctor for treatment).
Tell your doctor if you have ever had:
a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency;
heart disease; or
if you are over 80 years old and have not recently had your kidney function checked.
You may develop lactic acidosis, a dangerous build-up of lactic acid in your blood. This may be more likely if you have other medical conditions, a severe infection, chronic alcoholism, or if you are 65 or older. Ask your doctor about your risk.
It is not known whether Metaglip will harm an unborn baby. Similar diabetes medications have caused severe hypoglycemia in newborn babies whose mothers had used the medication near the time of delivery. Tell your doctor if you are pregnant or plan to become pregnant while using this medicine.
Metformin may stimulate ovulation in a premenopausal woman and may increase the risk of unintended pregnancy. Talk to your doctor about your risk.
You should not breast-feed while you are taking this medicine.
How should I take Metaglip?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.
Take Metaglip with meals.
Drink plenty of liquids while you are taking Metaglip.
Low blood sugar (hypoglycemia) can happen to everyone who has diabetes. Symptoms include headache, hunger, sweating, irritability, dizziness, nausea, and feeling 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 dose or medication schedule.
Metaglip is only part of a complete treatment program that may also include diet, exercise, weight control, blood sugar testing, and special medical care. Follow your doctor's instructions very closely.
Store at room temperature away from moisture and heat.
Your doctor may have you take extra vitamin B12 while you are taking Metaglip. Take only the amount of vitamin B12 that your doctor has prescribed.
What happens if I miss a dose?
Take your dose as soon as you can, but only if you are getting ready to eat a meal. If you skip a meal, skip the missed dose and wait until your next meal.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose can cause severe hypoglycemia or lactic acidosis.
What should I avoid while taking Metaglip?
Avoid drinking alcohol. It lowers blood sugar and may increase your risk of lactic acidosis.
If you also take colesevelam, avoid taking it within 4 hours after you take Metaglip.
Metaglip side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Stop using Metaglip and call your doctor at once if you have:
heart problems-- swelling, rapid weight gain, feeling short of breath;
severe hypoglycemia--extreme weakness, blurred vision, sweating, trouble speaking, tremors, stomach pain, confusion, seizure; or
lactic acidosis--unusual muscle pain, trouble breathing, stomach pain, vomiting, irregular heart rate, dizziness, feeling cold, or feeling very weak or tired.
Common side effects may include:

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What other drugs will affect Metaglip?
Many drugs can affect Metaglip, making this medicine less effective or increasing your risk of lactic acidosis. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all your current medicines and any medicine you start or stop using.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
