Contraceptive Implant Patient Advice - Barrack Lane Medical Centre

Contraceptive Implant (Nexplanon)

Before your appointment

• Please use a reliable method of contraception before your implant fitting so we can be sure you are not pregnant.
• You may need to continue your current contraception for 7 days after the implant is fitted.
• If you are only using condoms, caps or diaphragms, please do not have sex from the start of your period until your appointment.
• If you are unsure or worried about pregnancy risk, contact the Nurse before your appointment.

During your appointment

• Please allow 30 minutes.
• Wear a short-sleeved top.
• The Nurse will explain the procedure.
• Your arm will be numbed with a local anaesthetic injection.
• The implant is placed just under the skin on the inner side of your upper arm.
• You will be asked to feel the implant after it is fitted.

After your appointment

• A small dressing will be applied and should stay on for around 3 days.
