implant fitting: What you need to know

Please read this information carefully when you book your implant fitting.

It is important that you read the information below when you book your appointment and then again before you attend your appointment to have a implant fitted.

If you are worried or have questions, you can call the clinic or speak to the nurse/doctor before the fitting, and it’s ok if you change your mind.

If you need to change or cancel your appointment, please contact the clinic as soon as possible. Contact details for all Brook clinics can be found in our service finder: brook.org.uk/find-a-service.

Important information

Please make sure you have read and understand the information below before you attend your implant appointment.

Contraception, pregnancy and STIs

It is very important that there is no chance of you being pregnant when you have your implant fitted (or re-fitted).

  1. Use condoms every time you have sex for three weeks before your implant fitting. If you have had unprotected sex (sex without a condom or contraception) in the three weeks before you implant appointment, the nurse or doctor will not be able to fit your implant.
  2. The ‘withdrawal method’ (pulling out) and natural family planning do not count as contraception ahead of an implant fitting.
  3. If you are already using a method of contraception, keep using it up until your fitting. This means you should keep taking your pill or using your patch, have the implant inserted before your injection runs out, or keep your coil until after the fitting. It is safe to have both methods at the same time. You may need to keep using your current method for up to seven days after your fitting, too, so make sure you tell the nurse/doctor if you are running out of pills or patches.
  4. If you think that your method of contraception may have failed, (e.g. if the condom broke or if you missed a pill) make sure you tell the nurse/doctor before they start your implant fitting.
  5. You may need to do a pregnancy test when you attend clinic, so please be prepared to provide a urine sample. If you do not do a pregnancy test when asked by the nurse/doctor, they may not be able to fit your implant.
  6. You shouldn’t have the implant fitted if you are at risk of having a sexually transmitted infection (STI). STIs are usually passed on through unprotected (without a condom) sex. Make sure you do an STI test before your appointment if you have had a new sexual partner since your last test. You can ask for a test at your local clinic or see if you can order one to do at home.
  7. The implant may not be effective at preventing pregnancy straight away and you might need to avoid sex or use another method of contraception for the first seven days after your fitting. Condoms are a good idea – if you need some you can ask at the clinic and they’ll give you some for free.

At the start of the appointment, the nurse/doctor will ask you to confirm:

  • I have followed the advice about contraception and not having sex ahead of my implant fitting and have not had unprotected sex within the last three weeks.
  • I understand that the nurse/doctor will not fit the implant if they are concerned that I may be pregnant.
  • I understand that I should not have the implant fitted if I am at risk of a sexually transmitted infection (STI), and if I might be at risk I will tell the nurse/doctor.
  • I understand that the implant might not prevent pregnancy immediately and agree to use another form of contraception, like condoms, or to not have sex for seven days after the fitting if advised.
  • I understand that the implant will not protect me from STIs if I have unprotected sex in the future.

Implant risks

There are risks involved in all medical procedures. Please make sure you understand the below risks associated with the implant. You can ask the doctor/nurse to explain in more detail at your appointment if you want to.

  1. No method of contraception is 100% effective. The implant has a very small risk of failure (less than 1 in 100 chance of pregnancy).
  2. After having the implant fitted, there may be significant or noticeable bruising around the insertion area (usually the inside of the upper arm), though this should fade within a couple of weeks.
  3. There may be a small scar in the insertion area.
  4. There is a small risk of infection after the implant fitting and you should keep an eye on it to make sure the area does not become red, hot and swollen.
  5. There is a rare risk of the implant moving (migration) into a vein rather than staying under the skin where it was fitted (intravascular insertion).
  6. There is a rare risk of damage to blood vessels supplying blood to the brain and spinal cord (neurovascular damage).
  7. It is possible that your bleeding pattern (periods) will change and that you may experience no periods, irregular bleeding or prolonged bleeding after the implant fitting.
  8. Occasionally, implants can be difficult or uncomfortable to remove.

At the start of the appointment, the nurse/doctor will ask you to confirm:

  • I understand that the implant is not 100% effective at preventing pregnancy.
  • I understand that there might be bruising after the implant fitting and that I may have a small scar.
  • I understand that there is a small risk of infection after the implant fitting.
  • I understand that there is a rare risk of implant migration and intravascular insertion.
  • I understand that there is a rare risk of neurovascular damage.
  • I understand that the implant may affect my periods and I may see changes to my bleeding pattern or have no periods.
  • I understand that removal of the implant can sometimes be difficult.
  • I agree to seek medical care if I can’t feel the implant, it feels broken, the insertion site feels red, hot or swollen, or I am worried that there is something wrong with my implant.

Preparing for your appointment

Please accept statistics, marketing cookies to watch this video.

Make sure that you have had breakfast/lunch on the day of your appointment, and that you are well hydrated (have had enough to drink). Don’t drink alcohol or take drugs before your appointment.

Having the implant fitted shouldn’t be painful, though it could be a bit uncomfortable. If you are worried, a painkiller can be taken around an hour before your appointment.

If you have any questions about the implant or about the fitting procedure, make a note of these and make sure you ask the nurse/doctor before they start the procedure.

Be sure to follow any other guidance given to you at the time of booking your appointment.

If you want to bring someone with you to your appointment, please call the clinic beforehand to let them know. If you do bring someone with you, it’s important to understand that there might be times where the nurse/doctor has to ask you sensitive or personal questions – you might want the other person to leave the room whilst you answer these.

FAQs

If you have anxiety around needles and are preparing for an implant procedure, there are several strategies you can use to make the experience more manageable. First, take time to understand the process by asking your healthcare provider to explain the steps in detail. Knowing what to expect can help reduce fear of the unknown. Bring a friend for emotional comfort, having someone with you can help you feel more at ease. Let your provider know about your anxiety so they can allow extra time, take breaks if needed, and ensure the procedure moves at your pace.

Distractions can also be helpful—consider listening to music during the procedure to shift your focus. Bringing a stress ball or engaging in mindfulness techniques like deep breathing can also help calm your nerves. Many clinics offer chaperones for added support, so don’t hesitate to request one. If sensation is a concern, ask about using a local anaesthetic or numbing cream to minimise discomfort during insertion, as you may feel some pressure but little to no pain.

To prepare mentally, practice relaxation techniques, such as progressive muscle relaxation or deep breathing exercises, to help calm your mind and body. Lastly, plan something comforting or enjoyable for after the procedure, like meeting a friend or indulging in a favourite activity, to reward yourself for facing the experience. Remember to communicate openly with your healthcare provider—they are there to support you and make the process as smooth as possible.


Bleeding patterns following the insertion of an implant can be unpredictable, especially during the initial months. The vast majority of individuals experience irregular bleeding, which may include spotting, prolonged periods, or no bleeding at all. This is a common side effect and varies from person to person. Over time, some find their bleeding patterns settle into a routine, while others may continue to experience irregularities. If you have concerns about your bleeding or if it becomes bothersome, don’t hesitate to reach out to your healthcare provider for advice or potential management options.

Bruising is a possible side effect after implant insertion, although it varies from person to person. Some people may experience mild bruising around the insertion site, which is usually due to the needle used to place the implant or the movement of the tissue during the procedure. The bruising typically fades within a few days to a week. If the bruising is significant or persists, it’s a good idea to consult your healthcare provider to ensure everything is healing as expected.

The level of discomfort during and after implant insertion varies from person to person. While most people experience only mild discomfort or a feeling of pressure during the procedure, some may feel slight pain or discomfort. You may also experience some soreness or bruising at the site afterwards, but this usually subsides after a few days. If you’re feeling particularly anxious about pain, speak to your healthcare provider in advance to discuss pain relief options.

After the implant is inserted, it’s important to care for the site to prevent infection and ensure proper healing. Keep the area clean and dry, and avoid touching the site with unwashed hands. You may notice a small scar, but it should heal over time.

Watch out for signs of infection at the insertion site. These can include the area feeling hot to the touch, becoming red, or becoming increasingly sore. If you experience any of these symptoms, it’s important to contact your healthcare provider as soon as possible.

It’s normal to feel the implant under the skin, but don’t play with or manipulate it excessively. If you cannot feel the implant at all, or if you have concerns about its position, be sure to follow up with your healthcare provider to ensure everything is in place and healing correctly.


After your implant fitting

Make sure you know when your implant is due to expire. It might be good to add a reminder to your Google or Apple calendar for three years’ time.

If you have any worries about the implant, you can get back in touch with Brook and a nurse/doctor will be able to support you.

If you think you may have an infection (if your arm is red, hot or swollen) or feel unwell, you should seek medical advice immediately.

Remember: there may be some bruising to the implant site shortly after your fitting, and you may see changes to your periods.

FAQs

The length of time you should keep your bandage on after the implant procedure will be discussed with you by your doctor or nurse. There isn’t a standard duration, as it can vary depending on your individual healing process and the specific care instructions provided. In general, the key is to keep the area clean and dry. Your healthcare provider will guide you on when it’s safe to remove the dressing, and when you can begin to gently clean the area.


You can typically resume sexual activity a few days after the implant insertion. However, to ensure immediate effectiveness, it’s important to consider the following: If you inserted the implant during the first 5 days of your period, it’s immediately effective.

Otherwise, you’ll need to use a barrier method of contraception, like condoms, for the first week.

If you were already using another reliable hormonal contraceptive before the implant insertion, it might be immediately effective. It’s best to consult with your healthcare provider to determine the specific effectiveness in your case.

It’s normal to experience some pain or discomfort after a contraceptive implant fitting. To ease the pain, try taking over-the-counter pain relievers like paracetamol or ibuprofen, applying a cold compress to the area, resting your arm, elevating it, and avoiding touching the insertion site.

You can generally return to most normal activities, such as light exercise, within a few days after the implant insertion. However, it’s important to listen to your body and avoid strenuous activities, like heavy lifting or intense workouts, for at least a week.
