Tonbridge Medical Group Coil and Implant Service
 If you would like to discuss having a coil or implant fitted, please call reception to arrange to speak to one of the GPs that are qualified to carry out these procedures.
Coils can be fitted at the surgery for contraception, emergency contraception, heavy periods or as part of hormone replacement therapy (HRT). 
Implants are fitted for contraception. They are small flexible rods that are placed under the skin in the upper arm, after making a small area of skin numb. 


Coil Fitting

Before a coil fitting appointment, we suggest that you watch the video on the following link.


  •        Please allow 30 minutes for the appointment
  •        Coils can be fitted at any time of your cycle as long as you are sure that you are not pregnant, ideally day 1-5 of your cycle
  •        They are effective as contraception after 7 days
  •        For coil changes, please do not have any unprotected sexual intercourse for 7 days before the procedure
  •        Mirena Coils are often used as womb protection when women are using HRT and are also the first line treatment for menorrhagia (heavy periods). 
  •        Some people take paracetamol or ibuprofen 20 minutes before attending,  as the procedure can sometimes be uncomfortable​
  •        A swab to check for infection is usually taken at the time of the fitting
  •        Any pain usually settles quickly, but we usually suggest that you take it easy for a few hours after the fitting, with no heavy exercise/lifting
  •        It can sometimes make women feel a little light headed or dizzy so it's advisable to have something to eat before your appointment and avoid heavy exercise prior to the fitting
  •        We usually advise no sex/tampons for a week after the fitting 
  •        Any risks are listed on the form on the sexual health matters link above
  •        You will be told at your appointment how long the coil will last for, so when it will need to be changed
  •        The coil has threads which hang through the cervix  into the top of the vagina. You will need to learn to examine yourself intermittently to check the coil threads can be felt
  •         Please call reception if you have severe pain after the fitting, a fever, heavy vaginal discharge, or if the coil comes out or you cannot feel the threads (and use additional contraception until you are examined)
Implant fitting

  • Implants can be fitted at any time in your cycle as long as you are sure that you are not pregnant, ideally on day 1-5 of your cycle 
  • They are effective as contraception after 7 days
  • Implants are usually fitted in your non dominant upper arm

  • A dressing and bandage will be applied which should be kept on for 2 days after the procedure
  • Your arm may ache for a 24hr period after the procedure, but if you have any ongoing issues please contact us
