c-rose-hips and Coumadin Interactions

Interactions between c-rose-hips(ascorbic acid) and Coumadin (warfarin)

warfarin and ascorbic acid (Minor Drug-Drug)

The use of ascorbic acid has been implicated in causing warfarin resistance. However, controlled clinical trials have not demonstrated clinically important variations in prothrombin times. The possibility of an interaction may be considered if warfarin resistance is encountered in patients taking high doses of ascorbic acid. Other anticoagulants may be affected as well, although data are lacking.
