Nexplanon (etonogestrel) is an implant placed in your arm to prevent pregnancy. It's a long-acting medication that continues to prevent pregnancy for up to 3 years after insertion. It's one of the most effective forms of birth control available. Unlike other birth control options that contain two hormones (estrogen and progesterone), Nexplanon (etonogestrel) only contains a progesterone called etonogestrel. The most common side effects include irregular vaginal bleeding (e.g., longer periods, spotting) and headaches.
The Nexplanon (etonogestrel) implant slowly releases etonogestrel, which is a progestin (a manmade form of progesterone). It works to prevent pregnancy by stopping your ovaries from releasing an egg, by making it difficult for sperm to enter the uterus (womb), and by preventing a fertilized egg from implanting in your uterus.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.

Nexplanon (etonogestrel) is long-acting and can prevent pregnancy for up to 3 years. If you choose to continue using Nexplanon (etonogestrel), you'll need to get it removed after 3 years and have a new one placed by your healthcare provider.
If Nexplanon (etonogestrel) is placed within 5 days of starting your period, it will work right away to prevent pregnancy. This means you won't need to use a back-up birth control method, such as condoms. If it's placed after the fifth day of your period starting, you'll need to use a back-up method for the first 7 days after insertion. If you're switching from another birth control method, talk to your provider about when you can expect Nexplanon (etonogestrel) to start working and if you need to use a back-up method at first.
Nexplanon (etonogestrel) is one of the most effective methods of birth control available. It is over 99% effective, meaning that fewer than one person out of every 100 gets pregnant while using this medication for 1 year. Pregnancy is more likely to happen if your implant isn't in the correct position. Call your provider if you aren't able to feel your implant on the inside of your upper arm.
Your healthcare provider will place Nexplanon (etonogestrel) under the skin of the inner side of your upper arm using a needle. The procedure should take a few minutes.
Your healthcare provider can remove Nexplanon (etonogestrel) any time within 3 years after it was placed. This is usually done in their office. Your provider will first put some numbing medication around the area where Nexplanon (etonogestrel) was inserted. Then, they'll make a small cut in your arm and gently remove the implant with forceps. After it has been removed, they'll close your wound and place a bandage. While you can remove the top bandage after 24 hours, you'll need to keep the wound closure adhesive on for 3 to 5 days.
People who took Nexplanon (etonogestrel) in clinical studies did report weight gain as a side effect. People typically gain an average of 3 to 4 pounds after having Nexplanon (etonogestrel) in place for 1 to 2 years. A small group of people stopped using Nexplanon (etonogestrel) because of weight gain. But it's unclear whether the weight gain was caused by the implant, or other reasons. If you do gain weight, it could be because your body is holding onto water and you might feel bloated. If you notice that you have gained a lot of weight since starting on Nexplanon (etonogestrel), let your provider know.
Acne is one of the most common side effects of Nexplanon (etonogestrel), so there's a good chance this might happen to you. Most acne caused by this medication is mild and can be treated with over-the-counter products. If your acne becomes severe or is too bothersome for you, let your provider know so you can discuss alternatives.
While the answer to this question is unique for everyone, it's possible to conceive as early as one week after having Nexplanon (etonogestrel) removed. If you're not sure whether you want to get pregnant after Nexplanon (etonogestrel) removal, make sure to use a condom.
Nexplanon (etonogestrel) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Nexplanon (etonogestrel) will be implanted just below the skin, so you can feel it through the skin at all times. If Nexplanon (etonogestrel) is inserted too deeply, it can damage the muscles, tissues, and blood vessels around it. It can also lead to unwanted pregnancies. Very rarely, implants that have been inserted too deeply can move to another part of the body and cause infections. If Nexplanon (etonogestrel) has been placed incorrectly, your provider will need to be removed and placed again. If there's ever a time you can't feel the implant, contact your provider right away and use a barrier method of protection (e.g., condoms, diaphragms) to prevent pregnancy until your provider confirms the implant is in the right place.
Nexplanon (etonogestrel) can commonly cause a change from your normal menstrual bleeding pattern, such as an absent period, spotting, or longer periods. If you're concerned with your menstrual cycle changes, talk with your provider. Most of the time, the kind of menstrual period you experience within the first 3 months after Nexplanon (etonogestrel) is placed is likely what will you'll continue to experience as long as the implant is in place.
If you happen to get pregnant while taking Nexplanon (etonogestrel), there's a small chance that the pregnancy may be ectopic (outside of the womb). Additionally, Nexplanon (etonogestrel) can raise the risk of ovarian cysts (small sacs of fluid in the ovary). Although they rarely cause problems and tend to go away without any treatment, contact your provider if you ever have serious pain in your stomach area so they can check you for an ovarian cyst or ectopic pregnancy.
There have been reports of blood clots in people using birth controls containing both estrogen and progestin. Blood clots can be very dangerous and lead to a heart attack, a stroke, or a pulmonary embolism (life-threatening blood clot in the lungs). Nexplanon (etonogestrel) only contains progestin, so it's unclear whether or not it carries the same risk for blood clots as combination birth controls. If you've ever had blood clots in the past, ask your provider whether Nexplanon (etonogestrel) is a good option for you.
In addition, you shouldn't get Nexplanon (etonogestrel) implanted if it has been less than 3 weeks since you delivered a baby because you're at a higher risk for getting blood clots during this time. Be sure to discuss all your past and present medical conditions with your provider before starting Nexplanon (etonogestrel). If you need to have surgery that will make it difficult for you to move much, ask your surgeon if you should have the implant removed before your procedure is done. Call 911 or get medical attention right away if you have pain in your legs or arms, chest pain, sudden severe headaches, trouble breathing, or sudden changes in your speech or vision.
Experts aren't sure if there's a higher risk of developing breast cancer from using combination birth control. But there are some cancer types that are sensitive to hormones in the birth controls. Because of this, people who have ever had breast cancer or have a strong family history of breast cancer should talk to their provider before using Nexplanon (etonogestrel) to see if this birth control is a good option for them. Remember to perform monthly breast self-exams and tell your provider about any changes you notice.
Nexplanon (etonogestrel) wears off quickly after it has been removed. Most people will begin to ovulate again within 2 weeks of removal, meaning you can become pregnant during your first menstrual cycle off Nexplanon (etonogestrel). Be sure to switch to a different form of birth control or use a backup method of protection (e.g., condoms, diaphragms) as soon as you have Nexplanon (etonogestrel) removed to prevent unwanted pregnancies.
If you experience symptoms of liver problems like yellowing of the skin or eyes, pain in the right upper stomach, or dark urine, stop using Nexplanon (etonogestrel) and contact your provider right away. It's unclear whether Nexplanon (etonogestrel) can raise your risk for tumor in the liver. But people with liver problems and liver cancer shouldn't use Nexplanon (etonogestrel).
If you've blood pressure that isn’t under control or within blood pressure goals, don’t use Nexplanon (etonogestrel). If you're taking medications to control your blood pressure, your provider might ask you to monitor your blood pressure regularly to make sure it doesn’t get unusually high. Most times, there aren't any obvious symptoms of high blood pressure. But if you notice changes in your vision, headache, a racing heart, or flushing, call your provider immediately.
Nexplanon (etonogestrel) can raise your sugar and cholesterol levels in the blood. If you have a history of having high blood sugar, your provider might need to check your blood sugar levels more often to make sure they don’t get unusually high.
Nexplanon (etonogestrel) can cause you to gain weight. You can keep track of your weight after you've started this medication. If you're gaining weight too much too fast, talk with your provider and they can discuss with you about other options for birth control.
Though rare, Nexplanon (etonogestrel) might cause new or worsening gallbladder problems. Tell your provider if you’ve had gallbladder problems in the past so they can monitor you more closely. Get medical help if you experience any of the following symptoms so your provider can check your gallbladder: yellowing of the skin or eyes, fever, chills, nausea or vomiting with severe pain in the right upper stomach, dark urine, or light-colored stools.
Nexplanon (etonogestrel) is placed under your skin in your upper arm by your healthcare provider at their office. Once placed, it can prevent pregnancy for up to 3 years.
