Advice before the fitting of an Intrauterine Device (IUD) or Intrauterine System (IUS)

Timing of your fitting depends on what contraception you are currently using:

If you are currently using a hormonal method (pill, patch, vaginal ring, injection or non-expired implant)   OR

If you are currently using condoms please ensure these are used for ALL penetrative vaginal sex


  • IUD/IUS can be fitted at any convenient time
  • Continue using your current method correctly until your fitting

If you are not using a regular method of contraception:

  1. Abstain from sex from day 1 of your period until the fitting (or abstain for 3 weeks if your periods are irregular) OR
  2. Arrange to use a short-acting form of contraception; e.g. pill, patch or vaginal ring and commence this at least 4 weeks before fitting.

If you need to replace your current IUD/IUS and it has not yet expired:

  • This can be done on any convenient day BUT please abstain from sex or use condoms correctly 7 days before the fitting

This is to ensure that you are not at risk of pregnancy in the event that we cannot fit the new device after the original one is removed.

On the day of your appointment:

  • Please arrive 15 minutes before your appointment for registration
  • Please allow at least 2 hours for the appointment. Although the procedure does not take this long, a few women need a little more time to recover after the procedure.
  • If you need to bring your child/children then you must bring someone to look after them while you are having the fitting
  • You may wish to bring a friend/partner with you but please be aware they will not be able to be in the room with you during the procedure.
  • If possible we advise you avoid driving immediately after your fitting
