Implant contraception insertion

Overview

A contraceptive implant is a small, flexible rod about the size of a matchstick that a healthcare provider places under the skin of your upper arm. It releases hormones that stop you from getting pregnant for up to 3 years.

Yes, contraceptive implants are a popular long-acting reversible contraception method worldwide, including in the UK.

The implant is used by people who can become pregnant and want reliable, long-term contraception without having to remember a pill or other daily method.

Symptoms

Common symptoms

• Mild bruising, swelling, or tenderness at the insertion site for a few days.
• Irregular bleeding or spotting, especially during the first 6 to 12 months.
• Some people have headaches, breast tenderness, or mood changes.

Causes

Main causes

• The implant is not used to treat a condition, but to prevent pregnancy. People choose it for convenience and high effectiveness.

When to see a doctor

See a doctor urgently if:

• If you have signs of infection at the insertion site (redness spreading, pus, fever).
• If the implant becomes bent or you cannot feel it under your skin.
• If you think you might be pregnant while the implant is in place.

Book a routine appointment if:

• Schedule a follow-up about 2 weeks after insertion to check the site and healing.
• See your healthcare provider for removal or replacement after 3 years (or earlier if desired).
• If you have any questions about side effects or how the implant works, ask during a routine visit.

Diagnosis

The implant is not a diagnostic procedure. It is placed during a quick clinical visit. Your provider will first check that you are not pregnant and discuss your medical history.

Tests that may be done

• A pregnancy test may be done before insertion.
• Your provider will examine your arm to find a suitable spot under the skin.

What to expect at your appointment

The insertion is done in a clinic. Your provider will numb a small area of your inner upper arm with a local anaesthetic. Then they use a special device to insert the rod just under your skin. The whole process takes about 5 to 10 minutes. You can go home straight away.

Treatment

The implant itself is a form of contraception, not a treatment for a medical condition. However, after insertion you may need to manage mild side effects. Occasionally, a healthcare provider may need to remove the implant for medical reasons.

Self-care at home

• Keep the insertion site clean and dry for 24 hours.
• Avoid heavy lifting or strenuous arm exercises for a few days.
• Take over-the-counter pain relief like paracetamol if the area is sore (check with your pharmacist or doctor).

Medical treatments

If you have bothersome side effects like prolonged irregular bleeding, your healthcare provider may suggest a short course of hormonal medication or consider removing the implant and discussing other options. Infections are treated with antibiotics. Rare problems like the implant moving require removal.

When is surgery considered?

Insertion and removal of the implant are minor procedures done in a clinic. They do not require surgery in an operating theatre. If the implant cannot be felt or has moved deeply, a minor surgical procedure may be needed to locate and remove it.

Living with this condition

Once the insertion site heals, you can go about your normal daily life. The implant does not affect your ability to exercise, swim, or work. You do not need to do anything special to maintain it.

Lifestyle tips

• Check the implant occasionally to make sure you can still feel it under your skin.
• If you use hormonal contraception for other reasons (like period pain), talk to your provider about how the implant fits in.
• Remind yourself when the 3 years are up to have it removed or replaced.

Diet and exercise

No special diet or exercise changes are needed. A healthy lifestyle supports overall well-being while using the implant.

Mental health and emotional wellbeing

Some people may experience mood changes with hormonal contraception, though this is not common with the implant. If you feel very down, anxious, or unhappy, talk to your healthcare provider. They can help you decide if a different method might be better.

Prevention

The implant itself is a form of pregnancy prevention. There is no disease to prevent. However, you can prevent complications like infection by keeping the insertion site clean and following aftercare instructions.

Complications

If left untreated

• Rarely, the implant may become infected if not cared for properly.
• If the implant moves deeper into the arm, it may be harder to remove.
• If you become pregnant while the implant is in place, the pregnancy may be ectopic (outside the womb) in rare cases.

Long-term outlook

For most people, the implant works very well and causes few problems. Serious complications are extremely rare. If you do have any issues, your healthcare provider can usually resolve them quickly. The implant is a safe, effective, and long-lasting contraceptive option.
