Understanding Nexplanon: Duration and Effectiveness 🌟
What is Nexplanon?
Nexplanon is a small, flexible rod about the size of a matchstick that is inserted under the skin of your upper arm. It's a popular form of long-term birth control that releases etonogestrel, a synthetic progestin, into your bloodstream to prevent pregnancy.
How it Works
The implant prevents pregnancy through multiple mechanisms:
- Inhibiting ovulation: It stops the ovaries from releasing eggs
- Thickening cervical mucus: This makes it difficult for sperm to enter the uterus
- Thinning the uterine lining: This reduces the likelihood of a fertilized egg implanting
Duration of Effectiveness ⏳
While Nexplanon is FDA-approved for 3 years of use, recent studies suggest it may be effective for up to 5 years. During the approved period, it maintains an effectiveness rate of over 99%, making it one of the most reliable forms of birth control available.
Effectiveness Timeline
| Time Period | Effectiveness Rate |
|---|---|
| Years 1-3 | >99% |
| Years 4-5* | ~95% |
*Based on emerging research, not yet FDA-approved
Factors Influencing Effectiveness
Several factors can affect how long Nexplanon remains effective:
- Body Weight: People weighing over 130% of ideal body weight may need earlier replacement
- Medication Interactions: Certain drugs, such as those used for epilepsy or tuberculosis, can reduce effectiveness
- Medical Conditions: Some conditions may impact hormone absorption

Note: Weight, medications, and other factors may affect Nexplanon's effectiveness. Always discuss these with your healthcare provider.
Removal and Replacement
When approaching the end of the effectiveness period, you have two options:
- Have the implant removed
- Have it removed and replaced with a new one during the same procedure
The removal process is straightforward and typically takes only a few minutes. A healthcare provider will numb the area, make a small incision, and remove the implant.
