Important Note

The following information is intended to supplement, not substitute for, the expertise and judgment of your physician, pharmacist or other healthcare professional. It should not be construed to indicate that use of the drug is safe, appropriate, or effective for you. Consult your healthcare professional before using this drug.





This medication is used to treat diabetes. Controlling high blood sugar helps prevent heart disease, strokes, kidney disease, circulation problems, and blindness.

How To Use

Take by mouth, three times daily with the first bite of a meal, as directed. Dosage is based on your medical condition and response to therapy. Your dosage may be adjusted to determine the most effective dose for you.

Side Effects

Stomach pain, gas or diarrhea may occur. If these effects persist or worsen, notify your doctor promptly. Unlikely but report promptly: rash. If you notice other effects not listed above, contact your doctor or pharmacist.


Tell your doctor your medical history, including: allergies, kidney disease, very high blood glucose (diabetic ketoacidosis), stomach/intestine/bowel disease (e.g., inflammatory bowel disease, digestion problems). During times of stress, such as fever, infection, injury or surgery, it may be more difficult to control your blood sugar. Consult your doctor as additional medication may be required. Consult your doctor or pharmacist to learn the symptoms of high or low blood sugar. Some symptoms of high blood sugar include thirst and increased urination. Low blood sugar may cause you to feel shaky, sweaty, hungry or have an increased pulse. Because miglitol prevents the breakdown of table sugar, you should have a readily available source of glucose (such as glucose tablets) to treat symptoms of low blood sugar if taking miglitol in combination with other medications to treat diabetes. Consult your pharmacist for details. Tell your doctor if you are pregnant before using this medication. This drug is excreted into breast milk. Because of the potential risk to the infant, breast-feeding while using this drug is not recommended. Consult your doctor before breast-feeding.

Drug Interactions

Tell your doctor of all prescription and nonprescription medication you may use, especially of: all diabetes drugs (e.g., sulfonylurea drugs such as glyburide), drugs that help the digestive process (e.g., amylase, pancreatin), charcoal. Do not start or stop any medicine without doctor or pharmacist approval.


If overdose is suspected, contact your local poison control center or emergency room immediately. Symptoms of overdose may include severe gas, diarrhea, or stomach pain.


Do not share this medication with others. It is recommended you attend a diabetes education program to understand diabetes and all important aspects of its treatment including meals/diet, exercise, personal hygiene, medication and getting regular eye, foot and medical exams. Consult your doctor or pharmacist. Keep all medical appointments. Laboratory and/or medical tests (e.g., liver and kidney function tests, fasting blood glucose, hemoglobin A1c, complete blood counts) will be performed to monitor for side effects and response to therapy. Regularly check your blood or urine for sugar, as directed by your doctor or pharmacist.
