What medications can interact with cranberry supplements?

Cranberry is considered safe with almost all medications. In medicinal doses it may increase the effect of anti-coagulation drugs like warfarin (Coumadin), causing bleeding.

Finally, note that cranberry juice is acidic, like orange juice, and as such may counteract the effectiveness of antacid drugs.
