What are the side effects of an expired Nexplanon implant?
Patient's Query
Hi doctor,
I had the Nexplanon birth control implant inserted around ten years back, and I was told it expires after a few years. However, I never had it removed.
I was also informed that after its expiration, the implant would no longer be effective in preventing pregnancy. I was also told that if a medical professional asks me if I am on any type of birth control, I have to say no.
I am now seeking a second opinion.
-
Could the expired implant still be affecting my ability to get pregnant?
-
Even if it is no longer effective for contraception, could keeping it past the expiration date have impacted my fertility in any way?
I have an appointment scheduled next week to have it removed, but I would like to know if there are any potential physical side effects or complications that could result from having left it in for so many years after it expired.
Please guide.
Thank you.
Hi,
Welcome to icliniq.com.
I read your query and understand your concerns.
If Nexplanon (Etonogestrel) was inserted around ten years ago, then yes, it has expired and is no longer providing any contraceptive protection. Once it passes its effective window, it stops releasing enough hormone to prevent pregnancy. Keeping the expired implant in your arm usually does not affect your fertility. It becomes inactive and just sits in place without interfering with your ability to conceive once it is removed.
There is typically no need for special investigations before removal, unless you have had unusual symptoms. However, if you experience irregular periods or trouble getting pregnant later on, a basic fertility workup (like hormone tests or an ultrasound) might be helpful.
No major concerns are expected unless you develop pain, swelling, or signs of infection around the implant site. In that case, it should be checked sooner. Right now, the plan is straightforward: get it removed at your upcoming appointment. There is no urgent harm, but it is better to take it out.
Fertility generally returns quickly after removal, so if you are trying to conceive, things should move along naturally. If your menstrual cycles do not normalize within a few months after removal or if you have trouble conceiving, a follow-up is a good idea.
In the future, try to remove or replace implants on schedule to avoid confusion. If you are not planning a pregnancy, use another form of contraception once the implant has expired.
I hope this information is helpful.
Thank you.
