title: Anaphylaxis from medroxyprogesterone acetate.
abstract: BACKGROUND
  More than 30 million women in more than 90 countries use depot medroxyprogesterone acetate as an injectable contraceptive agent, and it is thought to be very safe. However, it should be recognized that serious and potentially life-threatening adverse effects can occur.
  
  
  METHODS
  A 40-year-old para 2 went into anaphylactic shock after receiving 150 mg of depot medroxyprogesterone acetate intramuscularly. She was not taking any other medication, and there was no history of allergy to food or cosmetics. She responded fully to immediate resuscitation. A repeat episode occurred when she received another dose 12 weeks later.
  
  
  CONCLUSIONS
  Although thought to be very safe, life-threatening adverse effects can occur with depot medroxyprogesterone acetate, and practitioners should be prepared for such eventuality.
