Can you provide me with a reference to confirm leaving a Nexplanon implant in place longer than recommended? #607/15

Q:        I am curious if you could provide me with the reference you are referring to in the question posted below.  I am a pharmiacist and have a patient who is in the exact same perdicament as the person the that question.  However, before she makes the decision to leave her Nexplanon in longer than the manufacturers recommended time period, she would like a reference showing the research backing up this idea.

Thanks for your help.

#911/12 :

Since I have no insurance, is it safe to leave my Implanon in my arm?  Can I leave my Implanon in for years?  I have no insurance at this time to pay for the removal of the implant.  Also, after 3 years, can I start taking the pills while the implant is still in my arm?



Implanon appears to remain fully effective for 4 years.  It may be left in place for more than 4 years unless you want to become pregnant.  Now, or after your Implanon has been in for 4 years you may start taking pills.  Both Implanon and low-dose pills are low-dose contraceptives.While no method is 100%, Implanon is extremely effective for the entire 3 years.  In fact, no pregnancies have been reported in the three published articles of 270 women who used Implanon for a 4th year.

Ovulation return may happen, but Implanon is still working through effects on cervical mucus and on the lining of the uterus.
