Can You Take Vitex While on Birth Control?

Linda Girgis | MD

Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.

Taking Vitex while on birth control is generally not recommended due to potential interactions. Vitex (chasteberry) works by influencing hormones like prolactin and progesterone, which can interfere with how birth control pills regulate your menstrual cycle. Studies show Vitex can reduce prolactin levels by up to 52% within three months, potentially affecting the hormonal balance that birth control maintains. This interaction may reduce contraceptive effectiveness or cause irregular bleeding. Some women report breakthrough bleeding, mood changes, or altered cycle timing when combining these treatments. Always consult your healthcare provider before adding Vitex to your routine if you're using hormonal contraception.
