Nexplanon is a prescription birth control device designed to prevent pregnancy for an extended period. This small, flexible implant is inserted discreetly beneath the skin of the upper arm, releasing hormones to offer effective contraception for up to five years. It represents a long-term, reversible option for individuals seeking to manage family planning.
How Nexplanon Works
The primary mechanism of Nexplanon involves the continuous release of a progestin hormone called etonogestrel. This hormone works in several ways to prevent pregnancy:
- It inhibits ovulation, meaning an ovary does not release an egg.
- It thickens cervical mucus, creating a barrier that makes it difficult for sperm to reach an egg.
- It alters the lining of the endometrium, making it less receptive to a fertilized egg.
These combined actions provide a highly effective method of birth control. The implant can be removed at any time if pregnancy is desired or if side effects become unmanageable.
Potential Side Effects
Like all medications, Nexplanon can cause side effects. Common side effects often include changes in menstrual bleeding patterns, such as irregular bleeding or spotting, headaches, and weight fluctuations. Other potential side effects may include vaginitis, acne, breast pain, abdominal pain, and mood changes. More serious, though less common, side effects can include blood clots, changes in metabolism, and ovarian cysts. Individuals experiencing severe or persistent side effects should consult a healthcare professional immediately.
Insertion and Removal Procedures
The insertion and removal of the Nexplanon implant are performed by a trained healthcare professional in a clinical setting. The procedure involves numbing the area on the inner side of the non-dominant upper arm with local anesthesia to minimize discomfort. The implant is then carefully placed just under the skin.
Before insertion, a pregnancy test is typically administered to ensure the individual is not pregnant. The ideal timing for insertion depends on the previous birth control method used or if the individual has recently given birth. For instance, if switching from a non-hormonal method, insertion is usually recommended between days 1 and 5 of the menstrual cycle. After childbirth, a waiting period of 21 to 28 days is generally advised.
Removal also involves local anesthesia and is performed by a healthcare professional. If continued contraception is desired, a new implant can be inserted during the same visit.
Effectiveness and Dosage
Nexplanon is available in a single strength of 68 milligrams (mg) and is approved for use for up to five years. It is considered one of the most effective birth control methods available. While highly effective, it is crucial for the implant to be removed by the end of the fifth year of use.
Important Safety Considerations and Warnings
Before receiving Nexplanon, it is essential to discuss your complete medical history and any medications, supplements, or herbal products you are currently taking with your doctor. Nexplanon can interact with certain drugs, including some antifungals and St. John’s wort.
A significant warning associated with Nexplanon concerns the risk of complications from improper insertion or removal. While rare, these complications can include the implant breaking or bending, infection, movement of the implant from the insertion site, numbness or tingling in the arm, and scarring. Due to these risks, the device is part of a specialized risk management program.
Other important health factors to consider include:
- Blood Clots: Hormonal birth control methods, including Nexplanon, may increase the risk of blood clots and serious cardiovascular events.
- Hormone-Sensitive Cancers: Individuals with a history of hormone-sensitive cancers, such as certain types of breast cancer, are generally not prescribed Nexplanon.
- Depression: Nexplanon can cause or worsen depression or other mood changes.
- Diabetes: The implant may affect blood sugar levels, potentially worsening diabetes.
- Genital Bleeding: It is not typically prescribed for individuals with unexplained irregular genital bleeding.
- Liver Problems: Those with liver issues, including liver tumors, may not be suitable candidates for Nexplanon.
- High Blood Pressure: Nexplanon can increase blood pressure, requiring close monitoring for individuals with hypertension.
- Allergic Reaction: An allergic reaction to Nexplanon or its ingredients is a contraindication.
For any questions or concerns regarding Nexplanon, consulting a healthcare professional is always recommended to determine if it is the right birth control option for your individual needs.
