- Avoid drastic dietary changes.
- Avoid herbs and supplements with anticoagulant/antiplatelet activity. Examples include garlic, ginger, bilberry, danshen, piracetam, and ginkgo biloba.
- Ensure consistent Vitamin K intake.
- Exercise caution with grapefruit products. Grapefruit inhibits CYP3A4 metabolism, which may increase the serum levels of R-warfarin.
- Exercise caution with St. John's Wort. This herb induces CYP3A4 metabolism, which may reduce the serum levels of R-warfarin.
