Cytotec (Oral)

Generic Name: misoprostol (Oral route)

mye-soe-PROST-ol

Oral route(Tablet)

Administration of misoprostol to women who are pregnant can cause birth defects, abortion, premature birth, or uterine rupture. Uterine rupture has been reported when misoprostol was administered in pregnant women to induce labor or to induce abortion. The risk of uterine rupture increases with advancing gestational ages and with prior uterine surgery, including Cesarean delivery. Misoprostol should not be used for reducing the risk of NSAID-induced ulcers in women of childbearing potential unless the patient is at high risk of developing gastric ulcers or complications. Women must have a negative serum pregnancy test within 2 weeks prior to beginning therapy, use effective contraceptive measures, and initiate therapy only on the second or third day of the next normal menstrual period. Oral and written warnings of the hazards of misoprostol, including the risk of possible contraception failure, must be given to the patient prior to initiating therapy .
