Mirena is a contraceptive that some women may find interest in as it offers some advantages over other contraceptives.  It is a type of intrauterine system (IUS) that contains levonorgestrel, a type of progestin that is a synthetic progestogen.  

Mirena specifically targets women who do not want to conceive for longer periods, as this contraceptive can be effective for up to five years.  Women taking Mirena don’t have to worry about taking contraception daily, weekly, or annually.  They only have to check the thread position with each period and go for an annual clinical check-up or review.  Mirena is not only for those who want to prevent pregnancy but can also be used by those who suffer from menorrhagia or heavy menstrual flows, dysmenorrhea, endometriosis, and recurring pelvic pain.

How does Mirena work? As with all IUS, a medical practitioner should be the one to insert the device to the patient’s uterus and under sterile conditions.  The procedure involves the dilation of the cervix.  This could be very uncomfortable and potentially painful at its worst so painkillers may be taken as prescribed by the doctor.  Once in place, the IUS releases 20 mg of levonorgestrel per day.  As contraceptive, it reduces ovulation.  Being a foreign object, the IUS also makes the endometrium produce prostaglandin and leukocytes that are deemed hostile to sperms and eggs.

Is Mirena for every woman who opts for intrauterine systems?  It is vital for the woman to discuss this option to her doctor or healthcare provider. Mirena is not for women who are at high risk of getting infections that may lead to pelvic inflammatory disease.  Other complications to be considered are the possible attachment of the IUS to the uterine wall and the occurrence of ovarian cysts.  Women should know the risks before using Mirena.
