WHAT YOU NEED TO KNOW

Inform your prescriber if you wish to use Vitex alongside progesterone-based HRT. Concurrent use is not recommended without monitoring, as effects may be unpredictable.

Why this interaction occurs

Vitex indirectly raises progesterone levels by suppressing prolactin via dopaminergic mechanisms and modulating the LH:FSH ratio. When combined with exogenous progestins in HRT, this dual modulation of the progesterone axis may produce excessive progestogenic effects or unpredictably alter therapeutic hormone balance.

Evidence

Evidence level: limited.
