What is HRT?
- Hormone Replacement Therapy (HRT), also known as Hormone Therapy (HT), is used to relieve menopausal symptoms by replacing hormones that the body reduces production of during menopause.
Menopause Overview
- Definition: Permanent end of ovarian function.
- Average Age: 51 years.
- Symptoms: Hot flashes, night sweats, vaginal dryness, painful intercourse, mood swings, depression, irritability, insomnia, and urinary incontinence.
Types of HRT
-
Estrogen Therapy:
- Only oestrogen; typically starts with a low dose.
- Forms: Pills, patches, gels, rings, creams, tablets, sprays.
- Recommended post-hysterectomy due to reduced long-term risks.
-
Combination Therapy (Estrogen-Progesterone):
- Oestrogen + progesterone, for women with a uterus to lower uterine cancer risk.
- Forms: Pills, patches, IUDs.
Administration Methods
-
Systemic HRT: Hormones enter the bloodstream, treating general menopausal symptoms like hot flashes and night sweats. Forms include pills, patches, sprays, and gels.
-
Local HRT: Direct application to treat vaginal dryness with lower hormone doses. Forms include creams, rings, and tablets.
Indications for HRT
-
Moderate-to-Severe Vasomotor Symptoms: For perimenopausal and early postmenopausal women with symptoms like hot flashes.
-
Vaginal Symptoms Only: Preferable to use local oestrogen.
-
Premature Ovarian Insufficiency (POI): HRT or hormonal contraceptives help manage early menopause symptoms in women under 40.
-
Osteoporosis Prevention: FDA-approved HRT regimens are available, though not recommended solely for osteoporosis by USPSTF.
-
Female Sexual Interest and Arousal Disorder (FSAID): Testosterone supplementation may be added to HRT after excluding other causes.
Age Considerations
- Under 50: Benefits of HRT generally outweigh risks.
- 50-60: HRT benefits typically outweigh risks.
- Over 60: Risks and benefits balance, so treatment should be individualised.
- Over 70: Risks often outweigh benefits.
Important Notes on HRT
- Not for Disease Prevention: HRT is not indicated for preventing cardiovascular disease, cancer, stroke, dementia, or other chronic conditions.
- Inclusion of Progesterone: Women with an intact uterus should include progesterone with estrogen to prevent endometrial cancer.
- Avoid Compounded Formulations: Compounded HRT lacks standardisation in safety, efficacy, and consistency.
- Shared Decision-Making: Patient values and preferences are central to HRT decisions, requiring thorough provider consultation.
