Understanding Implanon and Nexplanon: Key Points for Users

As a retired doctor, I can share insights into Implanon and Nexplanon, the contraceptive implants widely used for long-term prevention of unwanted pregnancies. Implanon or Nexplanon are both brands of etonogestrel implants. For the sake of comparison, we will use the term Nexplanon throughout this article.

How Effective Are Nexplanon Implants?

The effectiveness of Nexplanon is remarkable, with a failure rate of less than 0.05 unwanted pregnancies per 100 women-years. This makes it a highly reliable form of contraceptive. However, it's important to note that these low failure rates can only be maintained if the implant is replaced at the recommended time. Failure to replace the implant on time can lead to an increased risk of pregnancy.

Signs of Contraceptive Failure

A suspect for contraceptive failure can arise when you start noticing subtle and often non-specific signs of pregnancy. Here are some indicators to look out for:

Feel Fatigued: Pregnancy often causes morning tiredness or fatigue, which can persist throughout the day. Back Pain: Pregnant women may experience a more pronounced lumbar lordosis (sway in the lower back), possibly due to the body's changing center of gravity. Changes in Breasts: This can include swollen or tender breasts, known as Montgomery tubercles, or darkening of the nipples, a common early symptom of pregnancy. Line on the Belly: A faint vertical line, known as the linea nigra, may appear on your underbelly as a result of increased melanin production. Morning Sickness: Despite its name, morning sickness can occur at any time of day. It is characterized by nausea and sometimes vomiting.

What to Do If You Suspect Contraceptive Failure

If you suspect that your contraceptive method has failed and you are experiencing pregnancy symptoms, the next step is to consult a healthcare professional. They can provide you with accurate information and assistance. Concrete signs to look out for include:

Physical Examination: A thorough physical examination can help identify possible pregnancy indicators. Pregnancy Test: A urine or blood test can confirm pregnancy with a high degree of accuracy. Follow-Up Consultation: Discuss your concerns and any ongoing changes with your doctor to ensure appropriate care.

Conclusion

While Implanon and Nexplanon are highly effective contraceptive devices, they are not without potential risks. It is essential to follow the instructions for replacements and recognize the early signs of pregnancy. Consulting with a healthcare provider can help confirm any concerns and ensure your continued health and well-being.
