Acarbose Warnings/Precautions:

Significant renal dysfunction (serum creatinine >2mg/dL): not recommended. Use glucose, not sucrose, to treat hypoglycemia. Stress. Monitor 1-hour postprandial glucose initially and during titration, then glycosylated hemoglobin. Monitor serum transaminases every 3 months during 1st year and periodically thereafter. Pregnancy (Cat.B): consider insulin instead. Nursing mothers: not recommended.

Alpha-glucosidase inhibitor.

Acarbose Interactions:

Caution with drugs that cause hyperglycemia (eg, diuretics, steroids, estrogens, phenothiazines, thyroid products, phenytoin, niacin, sympathomimetics, calcium channel blockers, isoniazid). Antagonized by intestinal adsorbents (eg, charcoal), pancreatin, amylase, other carbohydrate-splitting enzymes. Monitor digoxin; and for hypoglycemia if used with insulin or a sulfonylurea. May result in unreliable measurements of 1,5-AG assay; use alternative methods to monitor glycemic control.

Transient flatulence, diarrhea, abdominal pain.
