The treatment effect can be affected if Glucobay and digestive enzyme or cholestyramine (anti-high blood fats) are taken at the same time. Acarbose can affect the effect of digoxin (a heart medicine) with concomitant treatment. Therefore, consult a physician before concomitantly using other medications.
