  • What is Nexplanon?

  • What is the most important information I should know about Nexplanon?

    Nexplanon is intended to prevent pregnancy. It does not protect against HIV infection (AIDS) and other sexually transmitted diseases.

    The Nexplanon implant may not be placed in your arm at all due to a failed insertion. If this happens, you can become pregnant. You should be able to feel the implant under your skin immediately after insertion. Tell your doctor if you cannot feel the implant.

    Insertion and removal of the implant can lead to pain, irritation, swelling, bruising, or scarring at the insertion site; infection; or injury to nerves or blood vessels in your arm. Also, scar tissue can form around the implant or the implant can break, making it difficult to remove; you may need surgery to remove the implant. In addition, the implant can come out by itself, which can result in you becoming pregnant. Use a back-up birth control method and call your doctor immediately if your implant comes out.

    You can experience longer or shorter bleeding during your periods or have no bleeding at all while you are using Nexplanon. Nexplanon can also lead to spotting. Tell your doctor immediately if you think you may be pregnant or if you notice any changes in your menstrual bleeding.

    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 doctor immediately if you think you are pregnant or have unexplained lower stomach pain.

    Cigarette smoking while using Nexplanon can increase your risk of serious side effects on the heart and blood vessels, including heart attack, blood clots, or stroke. Your risk of getting serious blood clots can increase during surgery or bed rest. Tell your doctor at least 4 weeks before going to surgery.

    Nexplanon can also increase your risk of cancer of your breasts or reproductive organs, high blood pressure, liver tumors, or gallbladder disease. Your doctor will monitor you for these conditions. Ask your doctor to show you how to examine your breasts.

    Tell your doctor immediately if you have lower leg pain that does not go away, severe chest pain or heaviness in your chest, sudden shortness of breath, coughing blood, sudden severe headaches, weakness or numbness in your arms or legs, trouble speaking, vision loss, yellowing of your skin or whites of your eyes, breast lumps, problems sleeping, lack of energy, tiredness, or depression.

  • Who should not take Nexplanon?

  • What should I tell my doctor before I take the first dose of Nexplanon?

    Tell your doctor about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Nexplanon. Also, talk to your doctor about your complete medical history, especially if you have had heart attacks or strokes; blood clots; liver disease, including liver tumors; unexplained vaginal bleeding; breast cancer or certain hormonally sensitive cancers; diabetes; high triglycerides or cholesterol; headaches; high blood pressure; depression; gallbladder, heart, or kidney disease; or allergies.
