AMS Guide to MHT/HRT Doses Australia only
This Information Sheet has been developed as a guideline only to MHT/HRT products available in Australia in November 2024. Hormone Replacement Therapy (HRT) is now referred to as Menopausal Hormone Therapy (MHT). The intention of this sheet is to help clinicians change their patients to higher or lower approximate doses of MHT if needing to tailor therapy, or remain within the same approximate dose if needing to change brands of MHT.

Notes
-
Can be given daily if adherence is an issue
-
There are insufficient data for the need to increase the dose of micronised progesterone with higher oestrogen doses, or safety of higher doses. Therefore, the current recommendation is 200mg of progesterone for 12 days on a cyclical regimen or 100mg per day on a continuous regimen. This may not be enough in terms of unscheduled bleeding with higher doses of oestrogen.
Patients commenced on continuous combined MHT should not bleed after the first 6 months of use. If they do bleed, they need investigating. Those using combined cyclic therapy should have a withdrawal bleed around the end of the progestogen phase and if they bleed out of cycle, too long or too heavily, they also need investigating.
If investigation of unscheduled or out of cycle bleeding discloses no endometrial abnormality, it may be appropriate to increase the dose of progestogen to 200mg daily for women using high dose oestrogen on a continuous regimen and to 300-400mg for 12 days per month for those using high dose oestrogen on a cyclic regimen.
The use of oestrogen plus progestogen is intended to reduce the risk of endometrial cancer to the level seen in an untreated population and not to zero. Consequently, women and their doctors should be aware of the importance of investigating any postmenopausal bleeding (see AMS Information Sheet Bleeding – perimenopausal, postmenopausal and breakthrough bleeding on MHT/HRT).
-
Safe continuous or cyclic dose of micronised progesterone for use with high dose oestrogen (75mcg patch or higher, or high dose oestrogel gels) is unknown due to insufficient data
