"the mirena worked for not getting pregnant and no periods. however, it gave me debilitating cystic acne. it started within 3-4 months after getting the mirena inserted.  i went to several doctors and dermatologists who all insisted that the mirena was not the cause. i spent thousands of dollars on acne prescriptions and countless depressed days due to the severity of the acne.  as a woman in my mid thirties,  it effected my career as well as my personal relationships and self esteem.  this went on for the next 5 years.  i didn&#039;t have the mirena removed on its expiration date, and noticed that after about 3 months after the expiration, my skin had miraculous improvement.  i had the mirena removed and have never suffered a breakout since."
