What is Nexplanon?
Nexplanon is a type of contraceptive implant which are birth control devices for women which provide long-term protection. Nexplanon is a flexible plastic rod about the size of a matchstick that is placed under the skin of the upper arm. The implant releases a hormone called progesterone which prevents pregnancy by suppressing ovulation or preventing the release of an egg each month. The implant thickens the mucus in your cervix to prevent sperm from entering your uterus. It also thins the lining of the uterus (endometrium) to prevent a fertilized egg from implanting.
How does Nexplanon Work?
The procedure is performed at your doctor’s office in less than a minute. Your doctor injects local anesthesia on your upper arm where the implant is inserted. A device is used to insert the implant beneath your skin. You may feel a pinching sensation during insertion. You will be able to feel the implant but won’t be able to see it after insertion.
Nexplanon is kept in place for three years and then must be removed and replaced in order to continue to prevent pregnancy. Removal takes around 20 minutes. Your doctor numbs your skin with local anesthesia and makes a small incision near the tip of the implant and pulls it out. An X-ray can help locate the device if your doctor can’t feel it.
