How you prepare

By Mayo Clinic Staff

Your health care provider will evaluate your overall health and do a pelvic exam before inserting Mirena. He or she may also recommend screening for STIs. You can have Mirena inserted anytime during your menstrual cycle if you've been consistently using another birth control method or you haven't had sex since your last period.

If you are breast-feeding, have irregular periods or haven't been consistently using birth control, you may need to take a pregnancy test before Mirena is inserted or have it inserted during a period. If you have Mirena inserted more than seven days after the start of your period, you should be prepared to use backup contraception for one week.

Taking a nonsteroidal anti-inflammatory drug, such as ibuprofen (Advil, Motrin IB, others), one to two hours before the procedure can help reduce cramping.
