Hypersensitivity to acarbose and/or to inactive constituents.
Chronic intestinal disorders associated with distinct disturbances of digestion and absorption. States which may deteriorate as a result of increased gas formation in the intestine (e.g. Roemheld's syndrome, major hernias, intestinal obstructions, and intestinal ulcers).
Acarbose is contraindicated in-patients with severe renal impairment (creatinine clearance <25 mL/min). Inflammatory bowel disease, such as ulcerative colitis and Crohn's disease, partial intestinal obstructions or in patients predisposed to intestinal obstruction or ileus. Since the information on its effects and tolerability in children and adolescents is still insufficient, Acarbose should not be used in patients under 18 years of age.
