Plan B can be taken while on Nexplanon, but it’s usually unnecessary and may not increase pregnancy prevention significantly.
Understanding Nexplanon and Its Effectiveness
Nexplanon is a small, flexible rod implanted under the skin of the upper arm that releases a steady dose of the hormone etonogestrel. This hormone primarily works by preventing ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to reduce the chance of implantation. Once inserted, Nexplanon provides continuous contraception for up to three years without requiring daily attention.
Its effectiveness is remarkable—over 99%—making it one of the most reliable birth control methods available. The failure rate is less than 1%, meaning fewer than one out of 100 women using Nexplanon will become pregnant in a year. This high efficacy drastically reduces the need for emergency contraception in most cases.
What Is Plan B and How Does It Work?
Plan B One-Step, often simply called Plan B, is an emergency contraceptive pill intended for use after unprotected sex or contraceptive failure. It contains levonorgestrel, a synthetic progestin hormone that primarily prevents or delays ovulation. If ovulation has already occurred, Plan B might be less effective.
Plan B must be taken within 72 hours (3 days) after unprotected intercourse for optimal effectiveness, with earlier administration providing better protection against pregnancy. It’s not meant as a regular birth control method but as a backup option during emergencies.
How Effective Is Plan B?
Plan B reduces the risk of pregnancy by approximately 75-89% when taken within the recommended timeframe. However, its effectiveness decreases as time passes after unprotected sex. It does not terminate an existing pregnancy and is ineffective if implantation has already occurred.
Can I Take Plan B While On Nexplanon?
Yes, you can take Plan B while on Nexplanon, but it’s generally unnecessary due to Nexplanon’s high effectiveness. If you suspect that your implant may not be working correctly—perhaps due to improper insertion or if it has been more than three years since placement—taking Plan B might offer additional reassurance.
However, because both methods rely on hormonal action to prevent ovulation or fertilization, taking Plan B while already using Nexplanon usually doesn’t provide extra protection beyond what the implant offers. In fact, there’s no evidence suggesting that combining these two hormonal contraceptives causes harm or significant side effects.
When Might Taking Plan B Be Considered While Using Nexplanon?
- If the implant was recently inserted: Sometimes it takes up to seven days after insertion for full contraceptive protection to kick in. During this window, if unprotected sex occurs, emergency contraception might be considered.
- If there are concerns about implant displacement or failure: Rarely, implants can move or fail prematurely.
- If you missed follow-up appointments: Proper medical checks ensure your implant remains effective.
- If you’re unsure about timing: For example, if you had unprotected sex before insertion or during gaps in protection.
It’s important to consult with a healthcare provider before taking Plan B while on Nexplanon to evaluate your specific situation.
Potential Interactions Between Plan B and Nexplanon
Both Plan B and Nexplanon contain progestin hormones but differ in type and delivery method—levonorgestrel in Plan B versus etonogestrel in Nexplanon. Since these hormones operate similarly by preventing ovulation and thickening cervical mucus, taking both simultaneously doesn’t typically cause adverse interactions.
However, taking additional hormones unnecessarily can sometimes lead to increased side effects such as nausea, headaches, dizziness, breast tenderness, or irregular bleeding. These symptoms are usually mild and temporary but worth noting if considering emergency contraception alongside an implant.
Table: Comparison of Nexplanon vs. Plan B
| Feature | Nexplanon | Plan B |
|---|---|---|
| Hormone Type | Etonogestrel (progestin) | Levonorgestrel (progestin) |
| Duration of Effectiveness | Up to 3 years continuous protection | Single use; effective up to 72 hours post-intercourse |
| Main Mechanism | Prevents ovulation; thickens cervical mucus; thins uterine lining | Delays ovulation; may prevent fertilization |
| Efficacy Rate | >99% | 75-89% when taken promptly |
| Usage Frequency | Implanted once every 3 years | Used only after unprotected sex/emergency situations |
The Science Behind Combining These Two Methods
Nexplanon’s continuous hormone release keeps ovulation suppressed almost all the time. When you take Plan B on top of that hormonal background, its primary function—to delay ovulation—is likely redundant because ovulation is already suppressed by the implant.
Therefore, adding Plan B doesn’t significantly improve contraceptive efficacy but may provide psychological comfort for some individuals worried about potential exposure risks. The body handles these hormones similarly without evidence of dangerous interactions or reduced effectiveness of either method.
Still, it’s wise not to rely on emergency contraception regularly if you have an effective long-term method like Nexplanon implanted.
Side Effects and Considerations When Using Both Together
Using both methods simultaneously can slightly increase hormone-related side effects compared to using either alone:
- Nausea: Mild stomach upset is common but usually subsides quickly.
- Irritability: Mood swings may intensify temporarily.
- Bloating: Water retention might feel more noticeable.
- Irrregular bleeding: Spotting or breakthrough bleeding could occur.
These side effects are generally short-lived and not dangerous. If severe symptoms arise or persist beyond a few days, consulting a healthcare professional is advisable.
The Importance of Medical Guidance Before Combining Contraceptives
Even though taking Plan B while on Nexplanon isn’t harmful in most cases, self-medicating without professional advice isn’t recommended for several reasons:
- Assessing true risk: Your healthcare provider can determine whether emergency contraception is necessary based on timing and individual factors.
- Avoiding unnecessary side effects: Medical guidance helps prevent overuse of hormones.
- Troubleshooting potential issues:If your implant has failed or moved out of place, your doctor can address this properly rather than relying solely on emergency pills.
- Your overall health profile:Certain medical conditions or medications might affect how these contraceptives work together.
- Counseling about future contraception plans:Your provider can help plan follow-ups or alternative methods if needed.
Nexplanon Maintenance: Ensuring Continuous Protection Without Emergency Backup
Regular check-ups after implantation ensure that your Nexplanon remains correctly positioned and functioning optimally. Most providers recommend follow-up visits within the first few weeks post-insertion to confirm placement via palpation or ultrasound if needed.
Afterward, annual visits help monitor any concerns like irregular bleeding patterns or side effects that could signal issues with hormonal levels or device positioning.
Proper use means you rarely need emergency contraception like Plan B unless unusual circumstances arise (e.g., implant removal without immediate replacement).
Avoiding Common Misconceptions About Emergency Contraception While Using Implants
Some believe that using any form of birth control means they must also carry emergency options at all times “just in case.” While having knowledge about emergency contraception is empowering and practical for unexpected situations like condom breaks or missed pills from other regimens, implants like Nexplanon drastically reduce those emergencies by design.
Taking extra pills unnecessarily doesn’t improve safety significantly but could confuse your body’s hormonal balance temporarily.

Frequently Asked Questions
Can I Take Plan B While On Nexplanon Safely?
Yes, you can take Plan B while using Nexplanon. Both are hormonal contraceptives, and taking Plan B as an emergency measure is generally safe. However, it’s usually unnecessary because Nexplanon is already highly effective at preventing pregnancy.
Is Taking Plan B While On Nexplanon Necessary?
Plan B is typically not needed if you have Nexplanon implanted correctly. Nexplanon has over 99% effectiveness, making the chance of pregnancy very low. Only consider Plan B if you believe your implant might not be working properly or if it’s past the three-year usage period.
Will Plan B Increase Pregnancy Prevention When Used With Nexplanon?
Using Plan B while on Nexplanon generally does not increase pregnancy prevention significantly. Both methods work by preventing ovulation, so combining them rarely provides extra benefit beyond what Nexplanon already offers.
Are There Any Risks in Taking Plan B While On Nexplanon?
No evidence suggests harmful interactions between Plan B and Nexplanon. Taking both together does not cause known adverse effects, but since Plan B is usually unnecessary with Nexplanon, it should be used only as a backup in specific situations.
When Should I Consider Taking Plan B If I Have Nexplanon?
You might consider Plan B if your implant was recently inserted incorrectly, has expired after three years, or if you have concerns about its effectiveness. In these cases, emergency contraception can provide additional reassurance against unintended pregnancy.
The Bottom Line: Can I Take Plan B While On Nexplanon?
Yes—you can take Plan B while using Nexplanon without harm. But chances are slim you’ll ever need it thanks to the implant’s superior reliability.
If you find yourself asking “Can I Take Plan B While On Nexplanon?” because something feels off—missed follow-ups, doubts about insertion timing—don’t hesitate to contact your healthcare provider first before popping an emergency pill. They’ll guide you best based on your unique situation.
Ultimately, trust in the proven effectiveness of your implant combined with professional advice will keep unwanted surprises at bay much better than relying on emergency backup alone.
