OVERDOSE

No serious adverse reactions were reported in tolerance studies in healthy non-pregnant female and healthy male subjects where mifepristone was administered in single doses greater than 1800 mg (ninefold the recommended dose for medical abortion). If a patient ingests a massive overdose, she should be observed closely for signs of adrenal failure.

CONTRAINDICATIONS

  • Administration of MIFEPREX and misoprostol for the termination of pregnancy (the “treatment procedure”) is contraindicated in patients with any of the following conditions:
    • Confirmed or suspected ectopic pregnancy or undiagnosed adnexal mass (the treatment procedure will not be effective to terminate an ectopic pregnancy) [see WARNINGS AND PRECAUTIONS]
    • Chronic adrenal failure (risk of acute renal insufficiency)
    • Concurrent long-term corticosteroid therapy (risk of acute renal insufficiency)
    • History of allergy to mifepristone, misoprostol, or other prostaglandins (allergic reactions including anaphylaxis, angioedema, rash, hives, and itching have been reported [see ADVERSE REACTIONS])
    • Hemorrhagic disorders or concurrent anticoagulant therapy (risk of heavy bleeding)
    • Inherited porphyrias (risk of worsening or of precipitation of attacks)
  • Use of MIFEPREX and misoprostol for termination of intrauterine pregnancy is contraindicated in patients with an intrauterine device (“IUD”) in place (the IUD might interfere with pregnancy termination). If the IUD is removed, MIFEPREX may be used.
This monograph has been modified to include the generic and brand name in many instances.
