They counteract the hormone deficiency that occurs at menopause. These pills contain oestrogen, and often progestogen, drugs. HRT helps to prevent ^Iosteoporosis,^i ^Iatherosclerosis^i and ^Iatrophic vaginitis^i (where the vagina becomes thin and dry). Pills are taken daily on a monthly basis to coincide with the menstrual cycle. Adverse effects include nausea, tenderness of the breasts, fluid retention and leg cramps.
