I got the Kyleena prescribed off-label to me after suffering from ridiculously heavy periods in my teens. I used to bleed 200mls+ on some periods and even Tranexamic acid didn’t help. This IUD has been an absolute life-saver and my periods are so much lighter.
I will admit I have experienced some side effects - I used to have clear skin 95% of the time, however since the IUD I permanently have 1 or 2 pimples around my jawline which can be quite annoying. My periods are often very long now (7-11 days) despite being light which also gets frustrating.
Those are the two main side effects I’ve experienced, but overall it’s been a positive experience.
