Estradiol/progesterone (E2/P4), sold under the brand names Bijuva and Juvenum, is a combined estrogen and progestogen medication which is used in the treatment of menopausal symptoms in postmenopausal women.

Bijuva (formerly TX-001HR/TX-12-001HR) is an oral combination of estradiol (E2), an estrogen, and progesterone (P4), a progestogen, which was developed by TherapeuticsMD and is approved in the United States for the treatment of menopausal symptoms in women. It is also under development for the treatment of endometrial hyperplasia in women. The medication contains 2 mg solubilized E2 and 200 mg P4 in each gelatin capsule. It is the first combination of E2 and P4 in oral capsule form that has been developed for clinical use. Bijuva is currently in phase III clinical trials for endometrial hyperplasia. The medication was approved by the Food and Drug Administration for the treatment of menopausal symptoms in October 2018. E2/P4 is available as an aqueous suspension of E2 and P4 encapsulated in microspheres for use by intramuscular injection once a month under the brand name Juvenum in Mexico. It was introduced for the treatment and prevention of menopausal symptoms like hot flashes, vulvovaginal symptoms, and osteoporosis in December 2014. The combination contains relatively low doses of E2 and P4 (1 mg and 20 mg, respectively) contained within microspheres that results in a slower release of the hormones. Studies of this formulation have been published. E2/P4 encapsulated in microspheres has been studied for use as a once-a-month combined injectable contraceptive but has not been further developed or introduced for medical use.
