Causes uterine contractions. Therapeutic Effects: Prevention of gastric ulceration from NSAIDs. With mifepristone terminates pregnancy of less than 49 days. Therapeutic Use: Prevention of gastric mucosal injury from NSAIDs, including aspirin, in high-risk patients (geriatric patients, debilitated patients, or those with a history of ulcers). With mifepristone for termination of pregnancy. Unlabeled Use: Treatment of duodenal ulcers. Cervical ripening and labor induction. Complications: CNS: headache. GI: abdominal pain, diarrhea, constipation, dyspepsia, flatulence, nausea, vomiting. GU: miscarriage, menstrual disorders. Medication Administration: ● PO (Adults): Antiulcer—200 mcg 4 times daily with or after meals and at bedtime, or 400 mcg twice daily, with the last dose at bedtime. If intolerance occurs, the dose may be ↓ to 100 mcg 4 times daily. Termination of pregnancy—400 mcg single dose 2 days after mifepristone if abortion has not occurred. ● Intravaginally(Adults): 25 mcg (1/4 of 100– mcg tablet); may repeat q 3– 6 hr, if needed. Contraindications/Precautions: Contraindicated in: Hypersensitivity to prostaglandins; ● OB: Should not be used to prevent NSAID-induced gastric injury due to potential for fetal harm or death; ● Lactation: May cause severe diarrhea in the nursing infant. Use Cautiously in: ● OB: Patients with childbearing potential should be counseled to avoid pregnancy during misoprostol therapy for prevention of NSAID-induced gastric injury. Pregnancy status should be determined before initiating therapy; ● Pedi: Safety not established.Exercise Extreme Caution in: When used for cervical ripening (unlabeled use) may cause uterine rupture (risk factors are late trimester pregnancy, previous cesarean section or uterine surgery or 5 previous pregnancies). Nursing Interventions: Assessment: ● Assess patient routinely for epigastric or abdominal pain and for frank or occult blood in the stool, emesis, or gastric aspirate. ● Assess women of childbearing age for pregnancy. Misoprostol is usually begun on 2nd or 3rd day of menstrual period following a negative pregnancy test result. ● Termination of pregnancy: Monitor uterine cramping and bleeding during therapy. ● Cervical Ripening: Assess dilation of cervix periodically during therapy Implementation: ● Do not confuse Cytotec (misoprostol) with Mifeprex (mifepristone). ● Misoprostol therapy should be started at the onset of treatment with NSAIDs. ● PO: Administer medication with meals and at bedtime to reduce severity of diarrhea. ● Antacids may be administered before or after misoprostol for relief of pain.
