What is the most important information I should know about Glucophage?
Do not use Glucophage if you have kidney disease, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin). Before taking Glucophage, tell your doctor if you have liver disease or a history of heart disease.
Some people have developed a life-threatening condition called lactic acidosis while taking Glucophage. Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting. If you need to have any type of x-ray or CT scan using a dye that is injected into a vein, you may need to temporarily stop taking Glucophage. Be sure the doctor knows ahead of time that you are using this medication.
Know the signs of low blood sugar (hypoglycemia) and how to recognize them, including hunger, headache, confusion, irritability, drowsiness, weakness, dizziness, tremors, sweating, fast heartbeat, seizure (convulsions), fainting, or coma (severe hypoglycemia can be fatal). Always keep a source of sugar available in case you have symptoms of low blood sugar.
What is Glucophage?
Glucophage is an oral diabetes medicine that helps control blood sugar levels.
Glucophage is for people with type 2 diabetes who do not use daily insulin injections. This medication is not for treating type 1 diabetes.
Glucophage may also be used for purposes other than those listed in this medication guide.
What should I discuss with my healthcare provider before taking Glucophage?
Some people have developed a life-threatening condition called lactic acidosis while taking Glucophage. Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting. You may be more likely to develop lactic acidosis if you have congestive heart failure. Older adults may also have a higher risk of developing lactic acidosis. Talk with your doctor about your individual risk.
Do not use this medication if you are allergic to Glucophage, if you have kidney disease or kidney failure, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with insulin). Before taking this medication, tell your doctor if you are allergic to any drugs, or if you have:
liver disease; or
a history of heart disease.
If you have any of these conditions, you may not be able to use Glucophage, or you may need a dosage adjustment or special tests during treatment.
FDA pregnancy category B. This medication is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment. It is not known whether Glucophage passes into breast milk or if it could harm a nursing baby. Do not take Glucophage without first talking to your doctor if you are breast-feeding a baby. Glucophage should not be given to a child younger than 10 years old. Extended-release Glucophage (Glucophage XR) should not be given to a child younger than 17 years old.
How should I take Glucophage?
Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor. Follow the directions on your prescription label.
Your doctor may occasionally change your dose to make sure you get the best results from this medication.
Take Glucophage with a meal, unless your doctor tells you otherwise. Some forms of metformin are taken only once daily with the evening meal. Follow your doctors instructions. Glucophage is only part of a complete program of treatment that also includes diet, exercise, and weight control. It is important to use this medicine regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
Do not crush, chew, or break an extended-release tablet (Glucophage XR). Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking the pill would cause too much of the drug to be released at one time. To be sure this medication is helping your condition, your blood will need to be tested on a regular basis. Your kidney function may also need to be tested. It is important that you not miss any scheduled visits to your doctor.
Your medication needs may change if you become sick or injured, if you have a serious infection, or if you have any type of surgery. Your doctor may want you to stop taking Glucophage for a short time if any of these situations affect you.
Take care not to let your blood sugar get too low, causing hypoglycemia. You may have hypoglycemia if you skip a meal, exercise too long, drink alcohol, or are under stress.
Know the signs of low blood sugar (hypoglycemia) and how to recognize them:
hunger, headache, confusion, irritability;
drowsiness, weakness, dizziness, tremors;
sweating, fast heartbeat;
seizure (convulsions); or
fainting, coma (severe hypoglycemia can be fatal).
Always keep a source of sugar available in case you have symptoms of low blood sugar. Sugar sources include orange juice, glucose gel, candy, or milk. If you have severe hypoglycemia and cannot eat or drink, use an injection of glucagon. Your doctor can give you a prescription for a glucagon emergency injection kit and tell you how to give the injection.
Your doctor may have you take extra vitamin B12 while you are taking Glucophage. Take only the amount of vitamin B12 that your doctor has prescribed.
If you need to have any type of x-ray or CT scan using a dye that is injected into a vein, you may need to temporarily stop taking Glucophage. Be sure the doctor knows ahead of time that you are using this medication.
Store Glucophage at room temperature away from moisture, heat, and light.
What happens if I miss a dose?
Take the missed dose as soon as you remember (be sure to take the medicine with food). If it is almost time for your next dose, skip the missed dose and take the medicine at the next regularly scheduled time. Do not take extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention if you think you have used too much of this medicine. You may have signs of low blood sugar, such as hunger, headache, confusion, irritability, drowsiness, weakness, dizziness, tremors, sweating, fast heartbeat, seizure (convulsions), fainting, or coma. An overdose of Glucophage may cause a life-threatening condition called lactic acidosis. Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting.
What should I avoid while taking Glucophage?
Avoid drinking alcohol while taking Glucophage. Alcohol lowers blood sugar and may increase the risk of lactic acidosis while you are taking this medicine.
What are the possible side effects of Glucophage?
Get emergency medical help if you have any of these symptoms of lactic acidosis: weakness, increasing sleepiness, slow heart rate, cold feeling, muscle pain, shortness of breath, stomach pain, feeling light-headed, and fainting. Stop using Glucophage and get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Call your doctor at once if you have any of these serious side effects:
