About your coil fitting appointment

Your appointment is for half an hour

What to do before your coil appointment

  • Please make sure that you have something to eat before your appointment.
  • The fitting process can be uncomfortable and you may wish to take a tablet painkiller that is safe for
    you, an hour or so before the procedure.
  • It is important that there is no chance you could be pregnant when we fit your coil. Do not have sex
    from the start of your period until the insertion, unless you are using a method of contraception
    reliably and consistently.
  • If you are having a coil exchanged for a new one, you should not have sex for 7 days before the
    appointment if your coil is in date. If your coil is out of date you should not have sex for 21 days (3
    weeks) before the appointment so that a pregnancy test is valid.
  • It is OK to have a coil fitted if you are bleeding; please attend your appointment as usual.

Having a coil fitted

  • Before you have a coil fitted, you will have an internal examination to find out the size and position of
    your womb. This is to make sure that the coil can be put in the correct place. An internal
    measurement is made of the length of the womb and then the coil is inserted.
  • It takes about 15 to 20 minutes to insert a coil. The vagina is held open, like it is during a cervical
    screening (smear test), and the coil is inserted through the cervix and into the womb.
    If necessary, a local anaesthetic can be applied although for most women this is not necessary.
    Entonox (‘Gas and Air’) is also available if required. Please note that you should not use Entonox if
    you have recently had a ‘burst eardrum’ or within 48 hours of scuba diving and that if you are driving
    yourself home you should make sure you feel competent to drive and that it is at least 20 minutes
    since you stopped using the Entonox.
  • Occasionally patients feel nauseous or faint afterwards and you may wish to consider bringing
    someone with you to accompany and drive you home. You are likely to get some bleeding after the
    procedure so please bring a sanitary pad with you. Most women experience some period-like
    discomfort for 24-48 hours after fitting, but then it usually settles.
