Mirena Side Effects

Mirena Side Effects to Report

There are a number of side effects with Mirena that you should report to your healthcare provider. These include but are not limited to:
  • Signs of pelvic inflammatory disease (PID), such as:
    • Prolonged or heavy vaginal bleeding
    • Unusual vaginal discharge
    • Lower abdominal pain (stomach pain)
    • Pain during sex
    • Fever and chills
    • Unusual vaginal bleeding
    • Severe abdominal pain (stomach pain)
  • Signs of an allergic reaction, including:
    • An unexplained rash
    • Hives
    • Itching
    • Unexplained swelling
    • Wheezing
    • Difficulty breathing or swallowing.
Let your healthcare provider know if, at any time, you cannot feel the removal threads of Mirena. This may signal that the device has been displaced and lost from the body, broken, or possibly perforated the uterus. Your healthcare provider can check the location of Mirena using an ultrasound or an x-ray.
