## Q&A

**Q: What is Implanon and how does it prevent pregnancy?**  
A: Implanon is a small, flexible 4-cm rod placed under the skin of the upper arm. It continuously releases the hormone etonogestrel (progestin) to inhibit ovulation, thicken cervical mucus to block sperm, and thin the endometrium.

**Q: Who is suitable for the Implanon contraceptive implant?**  
A: Implanon is suitable for women needing low-maintenance, reversible birth control, including postpartum mothers, nursing women, and those unable to tolerate estrogen-based contraceptives.

**Q: How is the implant inserted and removed in Malaysia?**  
A: A certified healthcare provider numbs the inner arm with local anesthesia and inserts or extracts the rod via a minor 5-minute procedure at government clinics (Klinik Kesihatan), LPPKN centers, or private clinics across Malaysia.

**Q: What are the common side effects of Implanon?**  
A: Common side effects include changes in menstrual bleeding patterns (irregular spotting, lighter periods, or amenorrhea), temporary mood fluctuations, mild weight changes, or localized tenderness at the insertion site.

**Q: Can breastfeeding mothers safely use Implanon?**  
A: Yes, Implanon contains only progestin and does not contain estrogen, meaning it does not adversely impact breast milk production, composition, or infant development.
