Hormone medication is regarded by specialists as the most effective treatment for menopausal symptoms, though it does come with certain risks, as is the case with nearly all medications. These risks are primarily associated with women who begin treatment later in menopause, use it for an extended duration (typically more than 5 years), and depend on factors such as the specific product, method of administration, dosage, and medical history. Oral hormone replacement therapy containing oestrogen slightly increases the risk of thrombosis, stroke, and gallbladder problems. When administered through the skin, the risk of thrombosis is lower; however, gallbladder problems may still arise. If you have a uterus, progesterone or progestogen is always required alongside oestrogen to prevent uterine cancer. Combined hormone replacement therapy is linked to a rare but increased risk of breast cancer when used over the long term. Hormone replacement therapy applied vaginally is minimally absorbed and does not show an increased risk of these complications.
At the same time, recent studies indicate that women who commence hormone replacement therapy at the appropriate time (before the age of 60) and continue it for several years during menopause generally experience longer and healthier lives on average. Hormone replacement therapy seems to lower the risk of cardiovascular diseases, dementia, osteoporosis, and overall mortality. These beneficial effects are particularly evident in women who initiate therapy around the onset of menopause.
Hormone replacement therapy is not recommended for women with (a history of) breast cancer, hormonal cancers, stroke, thrombosis, liver disease, or abnormal vaginal bleeding.
Side effects of hormone replacement therapy
As hormone levels increase and/or the correct hormone dosage is determined, some side effects may occur during the first months of treatment:
- Headaches
- Nausea
- Breakthrough bleeding
- Tender or sensitive breasts
