Interaction guide

Cranberry and warfarin context

Cranberry juice, capsules, and urinary-health blends are sometimes used casually, but warfarin context changes the safety conversation.

Default spacing rule

If warfarin is part of the medication plan, ask the prescribing clinician or anticoagulation clinic before adding cranberry products or changing intake. Do not self-adjust medication based on supplement labels.
