Question: IUD (Mirena) effectiveness after 5 years

 pdocherty26380 - Wed May 27, 2009 6:30 am

I had been fitted with a IUD (Mirena) just over 5 years ago (5years 1.5month approx) and am due to have this removed in 3 days. Recently I have been feeling and being sick, which is not like me, and am wondering if there is a possibility of pregnancy here. I will ofcourse speak to my doctor very soon but woudl like to hear some advise on whether or not this is possible?

Many Thanks,

User avatar Hello,
It is unlikely since Mirena is a highly effective method and when manufacturers test for a period of reliability, they usually figure in a little wiggle room so at this early date of expiration you are most likely fully protected, though it is advised that you replace it now. I suspect your signs of illness are coincidental but because it is 99.9%
effective; not 100%, there is always a very slight chance of it happening in spite of the IUD. You can always do a home pregnancy test if you continue to have symptoms that do not resolve.

Best wishes.
