What Is Nexplanon and How Does It Work?
Nexplanon is a long-term, reversible prescription birth control implant placed just under the skin of the upper arm. It contains the active drug etonogestrel, a type of progestin hormone, and is approved to prevent pregnancy for up to five years. The implant can be removed at any time by a healthcare professional if you decide to become pregnant or wish to discontinue its use.
This contraceptive works through multiple mechanisms. Primarily, it prevents ovulation, which is the release of an egg from the ovaries. Additionally, it thickens cervical mucus to block sperm from reaching an egg and alters the lining of the uterus to prevent implantation.
The Insertion and Removal Process
A healthcare professional must perform both the insertion and removal of the implant in a clinical setting. The device is placed under the skin on the inner side of your non-dominant arm. Local anesthesia is used to numb the area and minimize discomfort during the quick procedure.
Before insertion, a pregnancy test is required to ensure you are not pregnant. The ideal timing for insertion depends on your current birth control method. For instance, if you are not currently using hormonal birth control, the implant is typically inserted between days one and five of your menstrual cycle. If you are switching from oral contraceptives, it is usually placed the day after your last active pill.
Potential Side Effects of Nexplanon
Like all hormonal contraceptives, Nexplanon can cause side effects. The most common reaction is a change in menstrual bleeding patterns, which may include irregular bleeding, spotting, or a complete absence of periods. Other reported side effects include headaches, vaginitis, weight gain, acne, breast pain, and mood changes such as depression.
While mild side effects often resolve within a few weeks, serious complications can occur. It is essential to monitor your health and contact a healthcare provider if you experience severe symptoms or signs of an allergic reaction.
Important Safety Considerations and Warnings
Nexplanon carries a boxed warning regarding the risks of improper insertion or removal. If the implant is not placed correctly, complications such as deep insertion, device migration, nerve damage, or difficulty removing the implant can occur. Consequently, only certified healthcare providers trained in the specific procedure can insert or remove the device.
Certain medical conditions may make Nexplanon unsuitable. Women with a history of blood clots, active liver disease, unexplained vaginal bleeding, or hormone-sensitive cancers like breast cancer should generally avoid this implant. Additionally, the hormone progestin can affect blood sugar levels and blood pressure, requiring close monitoring for individuals with diabetes or hypertension.
Before choosing Nexplanon, discuss your complete medical history, including any medications or herbal supplements you take, with your doctor to ensure it is a safe and effective option for your reproductive health.
