Progestin implants are a form of birth control used to prevent pregnancy.
Progestin implants consist of several small rods about the size of matchsticks that are placed beneath the skin. The rods contain progestin, which is similar to the female hormone progesterone. The rods are usually inserted under the upper arm. With progestin implants, a woman can get long-term, reversible birth control for up to 5 years.
These progestin rods prevent pregnancy in the following ways:
Progestin implants are one of the most effective forms of birth control. They are nearly as effective as sterilization. They do not protect against sexually transmitted diseases, or STDs.
The procedure for inserting progestin implants is done in the healthcare provider's office. It takes about 20 to 30 minutes and is done under sterile conditions. Local anesthesia is used to prevent pain.
A woman can go home and return to normal activities right after the implants are inserted.
The arm is tightly wrapped for 24 hours. Mild bruising and discomfort are generally felt for the next 1 to 2 days. Over-the-counter pain medicines, such as acetaminophen or ibuprofen, can be used as needed for pain or swelling.
Progestin implants are effective for as long as 5 years. At that time, they can be removed in the healthcare provider's office under local anesthesia. After the rods are removed, a woman's chances of becoming pregnant are not delayed as with some other forms of birth control. Her fertility returns within 24 hours.
There is less chance of getting pregnant with progestin implants than with oral contraceptives, or birth control pills. A woman does not need to remember to take a pill every day. Unfortunately, many women develop irregular vaginal bleeding. These problems may lead to a desire for implant removal. The irregular bleeding tends to improve after 3 to 6 months. Following are other possible side effects:
Any new or worsening symptoms should be reported to the healthcare provider.
