What are the side effects of hormone replacement therapy (HRT)?
If you are taking oestrogen, you may experience some side effects. These include nausea, headaches, and mood swings. Oestrogen may also cause breast tenderness, fluid retention, fluctuating weight, and eye irritation when wearing contact lenses. Progestogens can produce similar side effects to oestrogen, and occasionally cause acne and skin rashes. Such side effects are usually temporary and disappear after 1-2 months of treatment.
