Mirena IUD levonorgestrel levels after 6 years?

[Posh5000]

Hi there,

I decided to have the Mirena IUD fitted 6 years ago for the treatment of Endio and will now need this replaced. Does anyone know how the hormonal side of the Mirena works in terms of longevity. ie Should I expect any side effects when this is replaced as the level of levonorgestrel has lessened over the 6 years and therefore I will receive a greater amount in the IUD when its put back in? Just looking to be pre warned. Thanks

Hello 👋🏻 I’ve had my mirena coil changed a few times now. The only thing that I noticed Initially was that I had a bit of Brain fog😁 The positive side was it improved my symptoms as id just started to spot a bit more etc where the hormone regarding the coil had started to deplete due to the longevity of having it. But other than that, nothing really changed. Everyone’s different I guess but I hope this helps.☺️Xx
