Pregnancy: Glucobay should not be administered during pregnancy, as no information from controlled clinical studies is available on its use in pregnant women.
Lactation: After administration of radiolabeled acarbose to lactating rats, a small quantity of the radioactivity was found in milk. There are as yet no corresponding findings in humans. However, as drug-induced effects of acarbose in milk have not been excluded in babies in principle, it is advisable not to prescribe Glucobay during the breastfeeding period.
