What is etonogestrel implant?

Etonogestrel implant contains a hormone that prevents ovulation (the release of an egg from an ovary). This medication also causes changes in your cervical mucous and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Etonogestrel implant is used as contraception to prevent pregnancy. The medicine is contained in a small plastic rod that is implanted into the skin of your upper arm. The medicine is released slowly into the body. The rod can remain in place and provide continuous contraception for up to 3 years.

Etonogestrel implant may also be used for purposes other than those listed in this medication guide.

What is the most important information I should know about etonogestrel implant?

Before receiving the etonogestrel implant, tell your doctor if you have an ovarian cyst, heart disease, high cholesterol, diabetes, gallbladder disease, a seizure disorder, or if you are overweight.

Etonogestrel implant is inserted through a needle into the skin of your upper arm. The medicine is released slowly into the body from the implant. The implant can remain in place to provide continuous contraception for up to 3 years.

If you need to have any type of medical tests or surgery, or if you will be on bed rest, you may need to stop using this medication for a short time. Any doctor or surgeon who treats you should know that you are using etonogestrel implant.

The etonogestrel implant must be removed by the end of the third year after it was inserted and may be replaced at that time with a new implant. If you choose not to replace the implant, your ability to get pregnant will return quickly. Start using another form of birth control right away if you wish to avoid an unintended pregnancy.

How is the etonogestrel implant used?

Use this medication exactly as it was prescribed for you. Do not use etonogestrel implants for longer than recommended by your doctor.

The timing of when you will receive this implant depends on whether or not you were using birth control before, and what type it was. Follow your doctor"s instructions.

Etonogestrel implant is inserted through a needle into the skin of your upper arm, just inside and above the elbow. You will receive the implant in your doctor"s office or other clinic setting. The skin of your upper arm will be treated with a numbing medicine to keep you from feeling pain during the insertion.

This implant must be inserted only by a physician or other healthcare provider who has been specially trained in the insertion of the etonogestrel implant. Incorrect placement of the rod too deeply can make it difficult or impossible to remove later on. If the rod is incorrectly inserted and falls out, you will not be protected from unintended pregnancy.

Once the implant is inserted, you should be able to feel it under your skin. Tell your doctor if you cannot feel the implant under the skin at any time while it is in place.

The medicine is released slowly into the body from the implant. The implant can remain in place to provide continuous contraception for up to 3 years.

If the implant is placed correctly, you will not need to use back-up birth control. Follow your doctor"s instructions.

If you need to have any type of medical tests or surgery, or if you will be on bed rest, you may need to stop using this medication for a short time. Any doctor or surgeon who treats you should know that you are using etonogestrel implant.

Your doctor will need to see you on a regular basis while you are using this medication. You may also need to have routine mammograms. Do not miss any appointments.

The etonogestrel implant must be removed by the end of the third year after it was inserted and may be replaced at that time with a new implant. If you choose not to replace the implant, your ability to get pregnant will return quickly. Some women have become pregnant within the first week after removal of an etonogestrel implant. Start using another form of birth control right away if you wish to avoid an unintended pregnancy.

What happens if I miss a dose?

Since the etonogestrel implant is inserted under the skin and remains in place for up to 3 years, you will not be on a dosing schedule. Be sure to see your doctor for removal of the implant by the end of the third year.

What happens if I overdose?

If the implant is correctly inserted, an overdose of etonogestrel is highly unlikely. Symptoms of an overdose may include nausea, vomiting, and vaginal bleeding.

What should I avoid while taking etonogestrel implant?

Etonogestrel implant will not protect you from sexually transmitted diseases--including HIV and AIDS. Using a condom is the only way to protect yourself from these diseases.
