A contraceptive implant is a small, flexible rod (about the size of a matchstick) placed under the skin of your upper arm. It releases a hormone called progestin to prevent pregnancy. Common brands include Nexplanon or Implanon.
How Does It Work?
- Prevents ovulation (stops the release of eggs from the ovaries)
- Thickens cervical mucus to block sperm from reaching the egg
- Thins the lining of the uterus to prevent implantation
Effectiveness
- Over 99% effective at preventing pregnancy
- Works for up to 3 years (varies by brand)
Insertion and Removal
- Inserted by a healthcare provider using local anaesthesia
- A quick, minor procedure
- Removal can be done anytime if you decide to stop
- Fertility returns quickly after removal
Benefits
- No daily routine (no pills to remember)
- Long-lasting protection
- Very discreet
- Safe for breastfeeding women (after 6 weeks postpartum)
Common Side Effects
- Irregular bleeding: spotting, lighter/heavier periods, or no periods (first 6–12 months)

Who Should Avoid It?

Important Notes
- Does not protect against STIs — use condoms for protection

eGynaecologist Advice
- You should consult your gynaecologist if you develop severe pain, redness, or pus at the insertion site (signs of infection) and if the implant has moved or you can’t feel it.
- You should seek immediate gynaecological advice if you notice sudden, severe abdominal pain (possible ectopic pregnancy).
- You should schedule a check-up 2–4 weeks after insertion to ensure proper placement.
