What is the implant?
The implant is used to prevent pregnancy. It's a thin rod about the size of a matchstick that is inserted under the skin (subdermal) on the inside of your upper arm.
The implant releases the hormone progestin to prevent pregnancy. Progestin prevents pregnancy in these ways: It thickens the mucus in the cervix. This makes it hard for sperm to travel into the uterus. It also thins the lining of the uterus, which makes it harder for a fertilized egg to attach to the uterus. Progestin can sometimes stop the ovaries from releasing an egg each month (ovulation).
The implant prevents pregnancy for up to 5 years. Talk to your doctor about how long you can use it. Once it is put in, you don't have to do anything else to prevent pregnancy.
The implant can only be inserted by your doctor or another trained health professional. It only takes a few minutes. This can also be done right after you give birth. Your doctor will remove the implant when it needs to be taken out.
Your doctor numbs the area and "injects" the implant under your skin. No cuts are made in your skin. To remove the implant, your doctor numbs the area, makes a small cut in the skin, and pulls the implant out.
How well does it work?
Implants are more than 99% effective for preventing pregnancy. That means that fewer than 1 out of 100 people who use the implant as directed will have an unplanned pregnancy.
Be sure to tell your doctor about any health problems you have or medicines you take. The doctor can help you choose the birth control method that is right for you.
