Can I Take vitex with birth control?

SUMMARY:

Caution: Vitex (chasteberry) can affect hormonal balance and may theoretically reduce the effectiveness of hormonal birth control; consult a healthcare provider and consider additional contraceptive protection until advised otherwise.

ADDITIONAL NOTES:

Vitex is an herbal product that can influence pituitary hormones (notably prolactin) and may alter menstrual bleeding patterns or interact with estrogen/progestin signaling. Potential effects include breakthrough bleeding or reduced contraceptive reliability; evidence is limited and largely theoretical. Use caution if you are taking combined hormonal contraceptives, progestin-only pills, implants, or IUDs, and avoid concurrent use without medical advice. Also be cautious if you take dopamine agonists/antagonists or other hormone-modulating drugs.
