Estradiol + Dydrogesterone contains Estradiol Hypericum Perforatum
ModerateHypericum perforatum, also called St John's Wort, is a herbal remedy that is suspected of making the liver work faster at breaking down certain medicines. This has not been firmly proven for St John's Wort. Estradiol is one of the medicines the liver may clear faster because of this effect. If you take St John's Wort, tell your doctor or pharmacist before using it with Estradiol.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
