Implant/Intrauterine system (IUS): Insert the implant on the same day the previous implant or IUS is removed.

If fitted at any other time in the menstrual cycle, it will take 7 days to become effective for contraception, and the patient should use extra precautions (such as condoms) for those 7 days. If the patient is switching from another form of contraception, it may be effective immediately, depending on the type being switched from.Pharmacotherapeutic group: Hormonal Contraceptives for Systemic Use, progestagens, ATC code: G03AC08 Breast-feeding: The implant should be inserted after the fourth postpartum week (see section 4.6). The woman should be advised to use a barrier method until 7 days after insertion. If intercourse has already occurred, pregnancy should be excluded.

From August 2016 to March 2017, a total of 25 patients underwent seed implantation in our hospital, including 17 male and 8 female patients. The average age was 65 years (64.64 ± 14.12 years), and the age range was 44–87 years. Seven patients had lung tumours, 6 had bone metastases, 2 had pancreatic cancer, 1 had cervical lymph node metastases and 1 had inguinal lymph node metastases, 2 had bladder cancer recurrence, 1 had pelvic metastases, 1 had lung cancer with adrenal gland metastases, 1 had maxillary sarcoma, 1 had lung cancer with liver metastases, 1 had vulvar cancer recurrence, and 1 had liver cancer with brain metastases. The pre-operative physical strength score (Karnofsky performance score, KPS) was > 60, the white blood cells (WBC) count was ≥4.0 × 10 9/L, and the expected survival time was > 3 months. Patients with tumour progression after radiotherapy and chemotherapy or patients who could not receive chemoradiotherapy were included. All patients were aware of their disease status and understood the possible treatment effect and adverse reactions. All patients voluntarily accepted the treatment method and signed a consent form for seed implantation surgery. The study was approved by the Ethics Committee of our hospital. Materials and devices

If you experience any of the following, you should see your GP or return to the sexual health clinic:

Changing from a progestagen-only contraceptive method (e.g. progestagen-only pill, injectable, implant, or intrauterine system [IUS]) If the implant is not inserted in accordance with the instructions and not on the correct day, this may result in an unintended pregnancy (see section 4.2 How to insert Nexplanon and When to insert Nexplanon). Signposting is important to help you structure the consultation: “Next, I’d like to talk about some of the additional benefits of having the implant and some of the potential disadvantages. Is that ok?.”
