[Six-monthly administration of medroxyprogesterone acetate (MPA) (author's transl)]

For more than six years the authors have studied the acceptability and the effectiveness of Medroxyprogesterone Acetate (450 mg) as a long acting contraceptive (six months). With a Pearl index of 0.85, the method was considered as effective whereas its acceptability was adversely influenced by the bleeding irregularities that take place during the first year of use. A good patient-doctor relationship could lessen this influence.
