Searle Warning Letter Concerning Use of Misoprostol in RU 486 Abortions
[Note: Following the FDA's approval of RU 486, the drug company Searle
has objected to the use of an ulcer-treating drug (Cytotec) it makes
being used as the second part of the abortion process involved with RU
486. The first step of RU 486 is a drug used to kill the unborn child
and Cytotec (misoprostol) is then misused to induce a miscarriage of the
aborted child. The following is the text of the Searle letter objecting
to the misuse of their drug.]

IMPORTANT DRUG WARNING CONCERNING UNAPPROVED USE OF INTRAVAGINAL OR ORAL
MISOPROSTOL IN PREGNANT WOMEN FOR INDUCTION OF LABOR OR ABORTION
Dear Health Care Provider:
The purpose of this letter is to remind you that Cytotec administration
by any route is contraindicated in women who are pregnant because it can
cause abortion. Cytotec is not approved for the induction of labor or
abortion.
Cytotec is indicated for the prevention of NSAID (nonsteroidal
anti-inflammatory drugs, including aspirin)-induced gastric ulcers in
patients at high risk of complications from gastric ulcer, e.g., the
elderly and patients with concomitant debilitating disease, as well as
patients at high risk of developing gastric ulceration, such as patients
with a history of ulcer.
The uterotonic effect of Cytotec is an inherent property of
prostaglandin E1(PGE1), of which Cytotec is stable, orally active,
synthetic analog. Searle has become aware of some instances where
Cytotec, outside of its approved indication, was used as a cervical
ripening agent prior to termination of pregnancy, or for induction of
labor, in spite of the specific contraindications to its use during
pregnancy.
Serious adverse events reported following off-label use of Cytotec in
pregnant women include maternal or fetal death; uterine
hyperstimulation, rupture or perforation requiring uterine surgical
repair, hysterectomy or salpingo-oophorectomy; amniotic fluid embolism;
severe vaginal bleeding, retained placenta, shock, fetal bradycardia and
pelvic pain.
Searle has not conducted research concerning the use of Cytotec for
cervical ripening prior to termination of pregnancy or for induction of
labor, nor does Searle intend to study or support these uses. Therefore,
Searle is unable to provide complete risk information for Cytotec when
it is used for such purposes. In addition to the known and unknown acute
risks to the mother and fetus, the effect of Cytotec on the later
growth, development and functional maturation of the child when Cytotec
is used for induction of labor or cervical ripening has not been
established.
Searle promotes the use of Cytotec only for its approved indication.
Please read the enclosed updated complete Prescribing Information for
Cytotec.
