In addition, talk to your health care provider about using NEXPLANON if you:
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.
Tell your health care provider right away if:
Besides changes in menstrual bleeding patterns, other frequent side effects that cause women to stop using the implant include:
Other common side effects include:
Implants have been reported to be found in a blood vessel, including a blood vessel in the lung. This is not a complete list of possible side effects.
For more information, ask your healthcare provider for advice about any side effects that concern you. You may report side effects to the FDA at 1-800-FDA-1088.
The implant may not be placed in your arm at all due to a failed insertion. If this happens, you may become pregnant. Immediately after insertion, and with help from your health care provider, you should be able to feel the implant under your skin. If you can't feel the implant, tell your health care provider.
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, then 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 professional 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 are:
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 health care provider right away if you think you are pregnant or have unexplained lower stomach (abdominal) pain.
Cysts may develop on the ovaries and usually go away without treatment but sometimes surgery is needed 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.
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:
The risk of serious blood clots is increased in women who smoke. If you smoke and want to use NEXPLANON, you should quit. Your health care provider may be able to help.
Tell your health care 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.
A few women who use birth control that contains hormones may get:
If you feel that the implant may have broken or bent while in your arm, contact your healthcare provider.
