Although isolated cases of interactions (raised prothrombin times, bleeding or hypoglycaemia) have been seen in patients taking anticoagulants and acarbose
or sulphonylureas, in general no important interaction appears to occur. A decrease in prothrombin time has also been seen with acarbose
The isolated cases of bleeding are not expected to represent a general interaction. No interaction has been seen between the oral anticoagulants and miglitol
, pioglitazone, repaglinide
, rosiglitazone, or voglibose.
