This Information Sheet has been developed as a guideline only to approximately equivalent doses of the different MHT/HRT products available in Australia in March 2017. HRT is now referred to as Menopausal Hormone Therapy (MHT). The intention of this sheet is to help physicians 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. Private/non PBS script products are marked with an * .
