INTERACTIONS
As vitamin K interferes with the effect of anticoagulant drugs (like Coumadin), the concurrent use of these agents should be avoided.
5-methyltetrahydrofolate (5-MTHF) supplementation is not recommended concurrent with methotrexate cancer therapy, as it can interfere with methotrexate's anti-neoplastic activity; however, this folate source has not been shown to interfere with the anti-inflammatory activity of methotrexate. An individual taking methotrexate for psoriasis or rheumatoid arthritis can safely take a supplement containing folate.
ADDITIONAL WARNINGS
