MIRENA
Mirena is a levonorgestrel releasing intra-uterine system. It is licensed in
the UK and Ireland as a contraceptive agent, for treatment of idiopathic menorrhagia
and, from August 2004, also for the progestogen component of HRT. It is particularly
useful for:
- Persistent progestogenic side effects from systemic HRT despite changes in type and route of progestogen.
- When contraception is required along with HRT in the perimenopause.
- When withdrawal bleeds on sequential HRT are heavy, after investigation if indicated (see WHEN TO REFER).
Progestogenic systemic absorption is minimal so reducing systemic progestogenic side effects. The endometrial effect of Mirena can significantly reduce bleeding and when used as part of an HRT regimen, 30 to 60% of women become amenorrhoeic. Although Mirena used for contraception is licensed for 5 years, the license for use for the progestogen part of HRT is currently 4 years.
