For postmenopausal endometrial protection alongside estrogen, typical dosing is 100mg daily continuous or 200mg daily for 12 days each cycle. For secondary amenorrhoea, 400mg daily for 10 days induces withdrawal bleeding. Capsules are taken at bedtime because of sedative metabolites; food slightly improves absorption.
Indications
Prometrium is approved for endometrial protection in postmenopausal women receiving estrogen, secondary amenorrhoea and selected ART indications. Off-label use includes premenstrual dysphoric disorder, perimenopausal symptoms and as a sleep aid in selected patients. According to current menopause guidelines, micronised progesterone is the preferred progestogen in HRT, particularly in women with cardiovascular risk factors or migraine.
