What is the contraceptive implant done with?

The rod is flexible and is placed just beneath the skin on the inner side of the upper arm by a trained clinician. Etonogestrel steadily enters the bloodstream and mainly prevents ovulation. It also thickens cervical mucus, which makes sperm movement more difficult. The implant is not placed in a blood vessel or inside the womb. It does not protect against sexually transmitted infections, and bleeding patterns may change after insertion.

Tell the clinician if you could be pregnant, have liver disease, have had unexplained vaginal bleeding, or use medicines or herbal products. Keep the dressing in place for the advised period and avoid rubbing the insertion site while it settles. Check that you can feel the rod when the clinician shows you how. Arrange review if it becomes difficult to feel, appears to move, or you want it removed.

Contact the clinic for increasing redness, warmth, swelling, pus, persistent numbness, or pain in the arm. Seek prompt assessment if the rod cannot be felt or the skin over it changes significantly. Urgent help is needed for severe allergic symptoms or sudden chest pain and breathing difficulty. A clinician should assess troublesome bleeding rather than assuming it will follow a predictable pattern.

Ask how etonogestrel prevents pregnancy, when the implant becomes effective, how medicines may interact with it, how the rod will be removed, and what bleeding changes should be reported.
