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 (release of eggs from the ovaries).
- Thickens cervical mucus to block sperm from reaching an egg.
- Thins the lining of the uterus to prevent implantation.
Effectiveness
- Over 99% effective at preventing pregnancy.
- Works for up to 3 years (duration depends on the brand).
Insertion and Removal
- Inserted by a healthcare provider in a quick, minor procedure using local anaesthesia.
- Removal is also done by a provider and can be done anytime if you wish to stop using it.
- The implant is reversible – fertility returns quickly after removal.
Benefits
- No daily routine (e.g., no pills to remember).
- Long-lasting protection.
- Discreet—no one can see it.
- Safe for breastfeeding individuals (after 6 weeks postpartum).
Common Side Effects
- Irregular bleeding: Spotting, lighter/heavier periods, or no periods at all (common in the first 6–12 months).
- Headaches, acne, or breast tenderness.
- Mood changes or weight gain (less common).
Who Should Avoid It?
- Pregnancy or suspected pregnancy.
- History of blood clots, liver disease, or breast cancer.

Important Notes
- Does NOT protect against STIs: Use condoms for STI prevention.

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.
