Mirena is an intrauterine device (IUD), which means an IUD, indicated to prevent pregnancy (contraception) or to treat excessively heavy periods (functional menorrhagia). It is inserted into the uterine cavity where it works by releasing a progestin (levonorgestrel) for a period of 5 years.
New undesirable effects (anxiety, dizziness, fatigue, irritability, etc.), not currently mentioned in information documents intended for healthcare professionals and patients, have been reported at European level. These adverse effects are currently being evaluated by the European Medicines Agency (EMA): the results are expected from June 2017.
A survey is also being carried out at the national level
For its part, the National Medicines Safety Agency (ANSM) which has observed in recent days an increase in adverse reaction reports in connection with the Mirena IUD, is also carrying out investigations at the national level on all of these reports of adverse reactions received.
Corn, “To date, in view of the available data, the increase and the nature of the declarations do not call into question the benefit / risk ratio of Mirena, which remains positive in its current indications” underlines the ANSM, which reminds that patients must be informed of the potential side effects of Mirena by their doctor at the time of choice of contraception and IUD insertion.
