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