IIs it safe for an Implanon implant to remain in place after 3 years of use if it cannot be removed? #308/11

 If a patient has been using the Implanon implant for 3 years and it cannot be palpated for removal, is it appropriate to leave the device in place?


Michele Wyylen, MD


Implanon was 100% effective for 4 years in the 240 women reported to have used it for a 4th year (this will be a sentence in the 20th edition of Contraceptive Technology, soon to be out).

 

This means that your patient’s Implanon implant will continue to be a contraceptive for a 4th year and possibly for longer.  So the problem from leaving Implanon in place is that it remains an effective contraceptive for some, still not completely understood duration of time.

 

This would be a problem were the patient to want to become pregnant.  Otherwise, leaving Implanon in place indefinitely would not be a problem and she should start using a contraceptive, certainly after 4 years, but perhaps sooner.

 

One thing to keep in mind, your Implanon is effective for 4 not 3 years, so you need not take contraception into consideration at all.  You do not need YAZ at all to prevent pregnancy.  Why not leave Implanon in place for most of the next year?

Q:        My Implanon implant is already 3 years old but I cannot have a new one inserted until September.  Can I use a backup contraceptive until that time and be protected?

 

Q:        I have the Implanon implant and it is due for removal on July 8, 2010.  However, I have booked a holiday and cannot get to the doctor until September 8, 2010.  Is it okay to use alternative methods of contraception or abstain until my implant is reinserted on the 9th of September?

 


A:       

Although definitely not formally approved for more than 3 years, none of the 240 women in the 3 reported studies of Implanon use in the 4th year after insertion became pregnant.  (Chapter by Dr. Elizabeth Raymond in the 20th edition of Contraceptive Technology).

It is looking more and more as though Implanon is effective for 4 years.  Isn’t this good news?

So you can use a backup contraceptive until your new Implanon implant is inserted and feel quite certain that you are protected.
