—As of March 31, 1993, our fluoxetine pregnancy database contained 1103 prospectively reported pregnancies. Of these prospective reports, outcomes are available from 544 (59 from clinical trials and 485 from spontaneous reports) of the 761 pregnancies that had potentially reached term. This is a 71% follow-up rate. Of these 544 pregnancies, 91 were electively terminated. Spontaneous abortion was reported in 72 (15.9%). There were two stillbirths. Perinatal major malformations were reported in 13 (3.4%).
