    Before getting NEXPLANON, please tell your doctor if you have any allergies to numbing medicines or antiseptics used to clean your skin. These medicines will be used when the implant is placed into or removed from your arm.

    here are some other possible risks with NEXPLANON

    improper insertion

    The implant may not be placed in your arm due to a failed insertion. If this happens, you may become pregnant.

    To ensure NEXPLANON is properly inserted, immediately after insertion, you and your healthcare provider will feel for the implant under your skin. If you can’t feel the implant, be sure to tell your healthcare provider.

    location and removal may be difficult

    Location and removal of the implant may be difficult or impossible because the implant is not where it should be. Special procedures, including surgery in the hospital, may be needed to remove the implant. If the implant is not removed, the effects of NEXPLANON will continue for a longer period of time.

    Implants have been found in the pulmonary artery (a blood vessel in the lung). If the implant cannot be found in the arm, your healthcare provider may use x-rays or other imaging methods on the chest. If the implant is located in the chest, surgery may be needed.

    other problems related to insertion and removal

    • Pain, irritation, swelling, or bruising at the insertion site
    • Numbness and tingling at the insertion site
    • Scarring, including a thick scar called a keloid around the insertion site
    • Infection
    • Scar tissue may form around the implant making it difficult to remove
    • The implant may come out by itself. You may become pregnant if the implant comes out by itself. Use a back-up birth control method and call your healthcare provider right away if the implant comes out
    • The need for surgery in the hospital to remove the implant
    • Injury to nerves or blood vessels in your arm
    • The implant breaks making removal difficult

    ectopic pregnancy

    If you become pregnant while using NEXPLANON, you have a slightly higher chance that the pregnancy will be ectopic (occurring outside the womb) than do women who do not use birth control.

    Unusual vaginal bleeding or lower stomach (abdominal) pain may be a sign of ectopic pregnancy.

    Ectopic pregnancy is a medical emergency that often requires surgery.

    Ectopic pregnancies can cause serious internal bleeding, infertility, and even death. Call your healthcare provider right away if you think you are pregnant or have unexplained lower stomach (abdominal) pain.

    ovarian cysts and breast cancer

    Cysts may develop on the ovaries and usually go away without treatment, but sometimes surgery is required to remove them.

    It is not known whether NEXPLANON use changes a woman’s risk for breast cancer. If you have breast cancer now, or have had it in the past, do not use NEXPLANON because some breast cancers are sensitive to hormones.

    serious blood clots

    NEXPLANON may increase your chance of serious blood clots, especially if you have other risk factors such as smoking. It is possible to die from a problem caused by a blood clot, such as a heart attack or a stroke.

    Some examples of serious blood clots are blood clots in the:

    • Legs (deep vein thrombosis)
    • Lungs (pulmonary embolism)
    • Brain (stroke)
    • Heart (heart attack)
    • Eyes (total or partial blindness)

    The risk of serious blood clots is increased in women who smoke. If you smoke and want to use NEXPLANON, you should quit. Your healthcare provider may be able to help.

    Tell your healthcare provider at least 4 weeks before if you are going to have surgery or will need to be on bed rest. You have an increased chance of getting blood clots during surgery or bed rest.

    other risks

    A few women who use birth control that contains hormones may get:

    • High blood pressure
    • Gallbladder problems
    • Rare cancerous or noncancerous liver tumors

    If you feel you have a broken or bent implant, please contact your doctor.

    Important Safety Information

    You should not use NEXPLANON if you are pregnant or think you may be pregnant; have or have had blood clots; have liver disease or a liver tumor; have unexplained vaginal bleeding; have breast cancer or any other cancer that is sensitive to progestin (a female hormone), now or in the past; or are allergic to anything in NEXPLANON.

    Talk to your healthcare provider about using NEXPLANON if you have diabetes, high cholesterol or triglycerides, headaches, gallbladder or kidney problems, history of depressed mood, high blood pressure, allergy to numbing medicines (anesthetics) or medicines used to clean your skin (antiseptics). These medicines will be used when the implant is placed into or removed from your arm.

    Immediately after the NEXPLANON implant has been placed, you and your healthcare provider should check that the implant is in your arm by feeling for it. If you cannot feel the NEXPLANON implant, contact your healthcare provider immediately and use a non-hormonal birth control method (such as condoms) until your healthcare provider confirms that the implant is in place. You may need special tests to check that the implant is in place or to help find the implant when it is time to take it out.

    The implant may not be placed in your arm at all due to failed insertion. If this happens, you may become pregnant. Removal of the implant may be very difficult or impossible if the implant is not where it should be. Special procedures, including surgery in the hospital, may be needed to remove the implant. If the implant is not removed, then the effects of NEXPLANON will continue for a longer period of time. Other problems related to insertion and removal include pain, irritation, swelling, bruising, numbness and tingling, scarring, infection, injury to the nerves or blood vessels, and breaking of the implant. Additionally, the implant may come out by itself. You may become pregnant if the implant comes out by itself. Use a back up birth control method and call your healthcare provider right away if the implant comes out.

    The most common side effect of NEXPLANON is a change in your normal menstrual bleeding pattern. In studies, one out of ten women stopped using the implant because of an unfavorable change in their bleeding pattern. You may experience longer or shorter bleeding during your periods or have no bleeding at all. The time between periods may vary, and in between periods you may also have spotting.

    If you become pregnant while using NEXPLANON, you have a slightly higher chance that the pregnancy will be ectopic (occurring outside the womb) than do women who do not use birth control. Ectopic pregnancies can cause serious internal bleeding, infertility, and even death. Call your healthcare provider right away if you think you are pregnant or have unexplained lower stomach (abdominal) pain.

    The use of NEXPLANON may also increase your chance of serious blood clots, especially if you have other risk factors, such as smoking. If you smoke and want to use NEXPLANON, you should quit. Some examples of blood clots are deep vein thrombosis (legs), pulmonary embolism (lungs), retinal thrombosis (eyes), stroke (brain), and heart attack (heart). It is possible to die from a problem caused by a blood clot, such as a heart attack or stroke. Tell your doctor at least 4 weeks before if you are going to have surgery or will need to be on bed rest, because you have an increased chance of getting blood clots during surgery or bed rest.

    Cysts may develop on the ovaries and usually go away without treatment, but sometimes surgery is needed to remove them.

    Besides changes in menstrual bleeding patterns, other common side effects reported in women using NEXPLANON include: headaches; vaginitis (inflammation of the vagina); weight gain; acne; breast pain; viral infection such as sore throats or flu-like symptoms; stomach pain; painful periods; mood swings, nervousness, or depressed mood; back pain; nausea; dizziness; pain and pain at the site of insertion.
