What is Miglitol used for?
Miglitol is used with a proper diet and exercise program to control high blood sugar in people with type 2 diabetes. Controlling high blood sugar helps prevent kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems. Proper control of diabetes may also lessen your risk of a heart attack or stroke. Miglitol works in your intestines to slow the breakdown and absorption of carbohydrates from foods that you eat. This effect helps lessen your blood sugar rise after a meal.
How should I take Miglitol?
Take this medication by mouth as directed by your doctor, usually 3 times daily with the first bite of a meal. The dosage is based on your medical condition and response to treatment.
Use this medication regularly to get the most benefit from it. To help you remember, take it at the same times each day.
Tell your doctor if your condition does not get better or if it gets worse (your blood sugar is too high or too low).

What side effects can occur from Miglitol?
Diarrhea, gas, or abdominal discomfort/pain may occur as your body adjusts to this medication during the first few weeks. These side effects usually lessen with time. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Miglitol does not usually cause low blood sugar (hypoglycemia). Low blood sugar may occur if this drug is prescribed with other diabetes medications, or if you do not consume enough calories from food, or if you do unusually heavy exercise. Talk with your doctor or pharmacist about whether the dose of your other diabetes medication(s) needs to be lowered.
Symptoms of low blood sugar include sudden sweating, shaking, fast heartbeat, hunger, blurred vision, dizziness, or tingling hands/feet. Do not use table sugar or drink non-diet soda to relieve these symptoms because miglitol slows the breakdown of table sugar. Carry glucose tablets or gel with you to treat low blood sugar. If you don’t have these reliable forms of glucose, eat some honey or drink a glass of orange juice to quickly raise your blood sugar. Tell your doctor right away about the reaction and the use of this product. To help prevent low blood sugar, eat meals on a regular schedule and do not skip meals. Check with your doctor or pharmacist to find out what you should do if you miss a meal.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor right away. Your dosage may need to be increased or you may need other drugs.
This medication may rarely cause a serious intestinal condition (pneumatosis cystoides intestinalis). Tell your doctor right away if you develop: diarrhea that doesn’t stop, constipation, blood/mucus in stool.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
Not everyone experiences these side effects. There may be some side effects not listed above. If you have any concerns about a side-effect, please consult your doctor or pharmacist.
What drugs may interact with Miglitol?

Beta blocker medications (such as metoprolol, propranolol, glaucoma eye drops such as timolol) may prevent the fast/pounding heartbeat you would usually feel when your blood sugar falls too low (hypoglycemia). Other symptoms of low blood sugar, such as dizziness, hunger, or sweating, are not affected by these drugs.
Many drugs can affect your blood sugar, making it harder to control. Before you start, stop, or change any medication, talk with your doctor or pharmacist about how the medication may affect your blood sugar.

What is the dose of Miglitol for an adult?
Usual Adult Dose for Diabetes Type 2
Individualize dose based on efficacy and tolerability:
Initial dose: 25 mg orally 3 times a day
-After 4 to 8 weeks, may increase to 50 mg orally 3 times a day if needed; after 3 more months, may increase to 100 mg orally 3 times a day if needed based on glycosylated hemoglobin
Maintenance dose: 50 mg to 100 mg orally 3 times a day
Maximum dose: 100 mg orally 3 times a day
-Take orally at the start (with first bite) of each main meal; patients should be adhering to a diabetic diet to minimize GI side effects.
-Some patients benefit from starting at 25 mg orally once a day with subsequent titration to 3 times a day to minimize GI side effects.
-If no further reduction in postprandial glucose or HbA1c is observed with titration to 100 mg three times a day, consider lowering the dose.
Use: As an adjunct to diet and exercise to improve glycemic control in patients with type 2 diabetes mellitus.
Renal Dose Adjustments
Significant renal dysfunction (CrCl less than 25 mL/min or serum creatinine greater than 2 mg/dL): Use is not recommended
Liver Dose Adjustments
No adjustment recommended
Gastrointestinal Adverse Effects:
-If gastrointestinal symptoms persist despite following a prescribed diet, dose reduction or discontinuation may be necessary.
-When given in combination with sulfonylurea agents or insulin, hypoglycemia may occur, if this occurs, dose adjustment of the sulfonylurea agent or insulin will be necessary.
-Take orally at the start of meal (with first bite)
-This drug should be titrated to reduce gastrointestinal side effects; patients should be instructed regarding the importance of following a diabetic diet.
-This drug may be used as monotherapy, or in combination with other antidiabetic agents.
-Patients receiving sulfonylureas or insulin may need a dose adjustment of these agents if hypoglycemia occurs.
-Glycemic control: During initiation and titration, 1-hour postprandial plasma glucose should be used to monitor therapeutic response; glycosylated hemoglobin levels (HbA1c) should be measured every 3 months to assess long-term glycemic control.
-Patients should understand the importance of adhering to a diabetic diet; gastrointestinal side effects are common upon treatment initiation, but should diminish with time.
-Hypoglycemia may occur, more commonly when used in combination with insulin or a sulfonylurea; patients should be instructed to treat hypoglycemia with oral glucose (dextrose) as sucrose (cane sugar) is not expected to correct hypoglycemia due to the action of this drug.
-During periods of stress such as fever, trauma, infection, or surgery, management of diabetes may change and patients should be advised to seek medical advice.
