The initial report is reviewed, as well as the results of subsequent i
nvestigations, and the current status of the following side effects at
tributed to the use of oral contraceptives: subjective symptoms such a
s mood and libido changes, also headache; melanoma; gallbladder diseas
e; liver tumors; sickle cell disease exacerbation; teratogenesis; ''po
st-Pill'' amenorrhea; atherogenesis; and diminished carbohydrate toler
ance. In many instances a cause-and-effect relationship appears to be
incorrect or highly improbable. In other instances the side effects ar
e clinically insignificant or so rare as to be of minimal importance.
Yet they continue to be listed by various authorities as validated sid
e effects or relative contraindications to oral contraceptive use. Thi
s, in turn, limits the access of many women to a highly effective form
of contraception. This re-examination of past history is intended to
modernize our concepts of the safety of this modality.
