Generic Name: miglitol (MIG-li-tol)
Brand Name: Glyset
Miglitol is used for:
Treating type 2 diabetes in adults. It is used along with diet and exercise. Miglitol may be used alone or in combination with other diabetes medicines (eg, insulin).
Miglitol is a glucosidase inhibitor. It works by slowing down the digestion of carbohydrates into glucose. This results in a smaller rise in blood sugar levels following a meal.
Do NOT use miglitol if:
- you are allergic to any ingredient in miglitol
- you have blockage of the bowel or if you are at risk for this problem
- you have inflammatory bowel disease, colon ulcers, or long-term (chronic) bowel problems that interfere with digestion or nutrient absorption
- you have diabetic ketoacidosis (high ketone levels) or severe kidney problems
Contact your doctor or health care provider right away if any of these apply to you.
Before using miglitol:
Some medical conditions may interact with miglitol. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:
- if you are pregnant, planning to become pregnant, or are breast-feeding
- if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
- if you have allergies to medicines, foods, or other substances
- if you have stomach or bowel problems, liver problems, or kidney problems
Some MEDICINES MAY INTERACT with miglitol. Tell your health care provider if you are taking any other medicines, especially any of the following:
- Insulin or sulfonylureas (eg, glyburide) because they may increase the risk of low blood sugar levels
- Digoxin, propranolol, or ranitidine because their effectiveness may be decreased by miglitol
This may not be a complete list of all interactions that may occur. Ask your health care provider if miglitol may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use miglitol:
Use miglitol as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take miglitol by mouth at the start (with the first bite) of each main meal, unless directed otherwise by your doctor.
- If you are also taking charcoal or digestive enzyme preparations (eg, amylase, pancreatin), ask your doctor or pharmacist how to take them with miglitol.
- If you miss a dose of miglitol, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use miglitol.
Important safety information:
- Proper diet, regular exercise, and regular blood sugar testing are important for best results with miglitol. Follow the diet and exercise program given to you by your health care provider.
- Tell your doctor or dentist that you take miglitol before you receive any medical or dental care, emergency care, or surgery.
- Carefully follow the regular testing of urine or blood glucose schedules given to you by your health care provider.
- Do NOT take more than the recommended dose without checking with your doctor.
- It may be harder to control your blood sugar during times of stress, such as fever, infection, injury, or surgery. Talk with your doctor about how to control your blood sugar if any of these occur. Do not change the dose of your medicine without checking with your doctor.
- Miglitol does not usually cause low blood sugar. However, low blood sugar may occur when it is used along with certain other medicines for diabetes (eg, insulin, sulfonylureas). Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you hungrier. It is a good idea to carry a reliable source of glucose (eg, tablets, gel) to treat low blood sugar. This will raise your blood sugar level quickly. Because miglitol prevents the breakdown of table (cane) sugar, be sure to use glucose (dextrose), not sugar or fruits, to treat symptoms of low blood sugar. Tell your doctor right away if this happens.
- Lab tests, including blood glucose and glycosylated hemoglobin levels, may be performed while you use miglitol. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Miglitol with should be used with extreme caution in CHILDREN; safety and effectiveness in children have not been confirmed.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using miglitol while you are pregnant. Miglitol is found in breast milk. Do not breast-feed while taking miglitol.
