CKS is no longer commissioned by the National Institute for Health and Clinical Excellence (NICE). NICE remains committed to providing a replacement service for CKS and is currently reviewing its options. In the meantime, although CKS content is now not being maintained, it still remains relevant and will continue to be made available. CKS content was generated under a programme of topic creation and update. To check if the topic you are viewing is current or out of date, please refer to the topic publication details by clicking on the 'How up-to-date is this topic?' link in the left hand menu on individual topic pages.
Contraception - Management
How does menorrhagia, fibroids, or previous ectopic pregnancy influence choice?
- Women with idiopathic menorrhagia
- Methods that can be used without restriction: combined oral contraceptives (COCs), combined contraceptive patch, combined contraceptive vaginal ring, and the levonorgestrel-releasing intrauterine system (IUS) (initiation), which all may reduce menstrual blood loss; sterilization.
- Methods that can generally be used (advantages generally outweigh the risks): progestogen-only pill (POP), progestogen-only injectables and implants, copper intrauterine devices (IUDs), the levonorgestrel-releasing IUS (continuation of use), barrier methods, and natural family planning methods (if the cycle is regular; if the cycle is irregular, a new user would find it more difficult to learn the method).
- Consider:
- The levonorgestrel IUS (Mirena®) as the first-line contraceptive option (licensed indication).
- The COC as the second line contraceptive option.
- The POP and progestogen-only injectables as third line contraceptive options.
- For information on non-contraceptive treatments, see the CKS topic on Menorrhagia.
- Women with a history of ectopic pregnancy
- All methods can be used without restriction.
- However, methods of contraception that inhibit ovulation (i.e. COCs, progestogen-only injectables and implants) are particularly suitable, as they reduce ectopic pregnancy to a greater degree compared with other methods.
- Women with uterine fibroids
- Without distortion of the uterine cavity: all methods can be used without restriction.
- With distortion of the uterine cavity: copper IUDs and the levonorgestrel-releasing IUS should not be used if they cannot be easily fitted. All other methods can be used without restriction.
Basis for recommendation
- These recommendations are based on guidelines published by the Faculty of Sexual and Reproductive Health Care (FSRHC), formerly the Faculty of Family Planning and Reproductive Health Care (FFPRHC) [FSRH, 2009b], and the National Institute for Health and Clinical Excellence [NICE, 2007b].
- Pharmacological treatments for heavy menstrual bleeding
- NICE recommends that pharmacological treatments be considered in the following order:
- Levonorgestrel-releasing intrauterine system (IUS) — provided long-term (at least 12 months) use is anticipated.
- Tranexamic acid, or nonsteroidal anti-inflammatory drugs (NSAIDs), or combined oral contraceptives (COCs).
- Norethisterone (15 mg) daily from days 5 to 26 of the menstrual cycle, or injected long-acting progestogens [NICE, 2007b].
