Is Vitamin B6 (Pyridoxine) Safe with Norethindrone?
Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Women on norethindrone-containing contraceptives experiencing depression, irritability, or PMS-like symptoms should discuss B6 supplementation with their provider. A dose of 25–50 mg of B6 daily is commonly used; doses above 100 mg/day long-term should be avoided due to risk of peripheral neuropathy.
Why this interaction occurs
Norethindrone, as a progestin component in combined or progestin-only oral contraceptives, contributes to disruption of tryptophan-kynurenine metabolism, increasing demand for B6 as a coenzyme. This depletion mechanism is compounded when combined with estrogen and may contribute to OC-associated depression and mood instability.
Evidence
Evidence level: moderate.
