Warning

  • May cause serious fetal harm (e.g., birth defects, abortion, premature birth, uterine rupture).1 5 70

  • Uterine rupture reported when misoprostol was administered in pregnant women to induce labor or to induce abortion; risk increases with advancing gestational age and with prior uterine surgery, including cesarean delivery.

  • Misoprostol should not be taken by pregnant women to reduce the risk of nonsteroidal anti-inflammatory agent (NSAIA)-induced ulcers.1

  • Misoprostol should not be used for reducing the risk of NSAIA-induced ulcers in women of childbearing potential unless the patient is at high risk of complications from gastric ulcers associated with use of the NSAIA, or is at high risk of developing gastric ulceration.1 In such women, pregnancy must be excluded before the start of treatment and prevented thereafter by use of reliable contraception.1 Misoprostol should only be initiated on the second or third day of the next normal menstrual period.1

  • Advise patients of the abortifacient property of misoprostol and warn them not to give the drug to others because of the danger to women of childbearing potential should the drug be taken by mistake.1

Introduction

Gastric antisecretory agent with protective effects on the gastroduodenal mucosa;1 2 3 13 15 16 25 26 27 31 35 37 47 57 60 72 76 77 78 79 80 84 85 86 87 88 89 91 94 95 127 a synthetic analog of prostaglandin E1 (alprostadil).1 5 10 11 13 20 25 26 27 31 55 76 78 85 95

Prevention of NSAIA-induced Ulcers

Treatment to reduce the risk of NSAIA-induced gastric ulcers in patients at high risk (e.g., concomitant debilitating disease, geriatric patients, history of upper GI ulcer) of developing complications (e.g., bleeding, perforation, death) from these ulcers.1 5 56 61 67 68 70 85 95 96 135 233

Contraindicated for this use in pregnant women.1

Not recommended for use in women of childbearing potential unless the woman is at high risk of developing gastric ulcers or of complications resulting from NSAIA-induced gastric ulcers.1

The American College of Gastroenterology (ACG) has published guidelines for the prevention of NSAIA-related ulcer complications.245 The guidelines state that misoprostol (administered in full doses of 800 mcg daily) is very effective in preventing ulcers and ulcer complications in patients taking NSAIDs, but use may be limited by adverse GI effects.245 There is evidence that lower doses (400–600 mcg daily) may also confer significant protection with a similar adverse effect profile to placebo.245

Termination of Pregnancy

Used in conjunction with misoprostol for termination of intrauterine pregnancy through 70 days of gestation, dated from first day of last menstrual period; duration of pregnancy may be determined by menstrual history or clinical examination, or with an ultrasonographic scan if duration of pregnancy is uncertain or ectopic pregnancy is suspected.241

The American College of Obstetricians and Gynecologists (ACOG) states that the medication abortion regimen supported by major medical organizations nationally and internationally includes mifepristone and misoprostol; if mifepristone is unavailable, then a misoprostol-only regimen is an acceptable alternative.244

Gastric Ulcer

Short-term treatment of active, benign, gastric ulcer [off-label];2 55 58 72 76 85 87 however, not considered a drug of choice.140

Maintenance treatment following healing of active gastric ulcer to reduce ulcer recurrence [off-label].72

Duodenal Ulcer

Short-term treatment of endoscopically or radiographically confirmed active duodenal ulcer [off-label];2 23 55 78 79 80 83 84 85 86 89 91 92 93 94 however, not considered a drug of choice.140

Labor Induction

Treatment to improve cervical inducibility (cervical “ripening”) in appropriately selected pregnant women with unfavorable cervices with a medical or obstetric need for labor induction [off-label].235 237 238 However, avoid such use in women with prior uterine surgery or cesarean section because of the risk of possible uterine rupture.235 237 238

Postpartum Hemorrhage

Prevention or treatment of serious postpartum hemorrhage [off-label] in the presence of uterine atony.1 237

Misoprostol Dosage and Administration

Administration

Administer orally.1 2 3 4 5

Also has been administered intravaginally, using tablets formulated for oral administration.1 235 237 238

Oral Administration

Prevention of NSAIA-induced ulcers: Administer in divided doses after meals and at bedtime.1 3 Avoid concomitant administration with a magnesium-containing or other laxative antacid to minimize the incidence of misoprostol-induced diarrhea.1

Termination of pregnancy: Administer misoprostol intrabuccally 24–48 hours following mifepristone administration.241 Place 2 misoprostol tablets in each side of the mouth between the cheek and gums for 30 minutes, then swallow any remnants with water or another liquid.241 Administer in an appropriate setting for the patient, taking into account that expulsion of uterine contents could begin within 2 hours following drug administration.241

Dosage

Adults

Prevention of NSAIA-Induced Ulcers
Oral

200 mcg 4 times daily.1 56 57 59 76 81 95 May reduce dosage to 100 mcg 4 times daily if higher dosage is not well tolerated;1 61 70 however, reduced dosage may be less effective.1 61 67 73 95 Alternatively, 200 mcg twice daily.1 60 Continue therapy for the duration of NSAIA therapy.1

Termination of Pregnancy
Oral

800 mcg intrabuccally (two 200-mcg tablets placed in each cheek pouch) 24–48 hours following mifepristone administration.241 Administration of misoprostol <24 or >48 hours following mifepristone administration may result in reduced efficacy of the combined regimen.241

Vaginal,†Sublingual†, or Buccal†

Alternatively, if mifepristone is unavailable, ACOG states misoprostol may be administered alone at a dose of 800 mcg vaginally, sublingually, or buccally.244 Repeat dose every 3 hours for up to 3 doses for the initial treatment regimen.244 The World Health Organization (WHO) does not specify a maximum number of misoprostol doses for this use.244

Gastric Ulcer†

Warnings/Precautions

Warnings

Fetal/Neonatal Morbidity and Mortality

Possible teratogenic and abortifacient effects; possible serious fetal harm when administered to pregnant women.1 5 70 (See Boxed Warning.)

Possible uterine contractions and uterine bleeding and expulsion of the products of conception.1 3 23 55

Uterine rupture reported when administered in pregnant women to induce labor or abortion.1

Possible congenital abnormalities (e.g., skull defects, cranial nerve palsies, facial malformations, and limb defects); sometimes associated with fetal death.1

Contraindicated in pregnant women for reducing the risk of NSAIA-induced gastric ulcers.1 Do not initiate therapy in women of childbearing potential until pregnancy is excluded and other necessary precautions (effective contraception) are ensured.1 5 13 64 70 85 Initiate therapy only after determining that patient is reliable and able to comply with effective contraceptive measures.1 Perform a reliable, blood pregnancy test within 2 weeks prior to beginning therapy.1 Initiate therapy on the second or third day of the next normal menstrual cycle, after a negative pregnancy test is reported.1

If inadvertently administered during pregnancy or if the patient becomes pregnant while receiving the drug, discontinue therapy and inform patient of the potential hazard to the fetus.1

Intravaginal use may result in uterine hyperstimulation, uterine tetany, uterine rupture, amniotic fluid embolism, pelvic pain, retained placenta, severe genital bleeding, shock, fetal bradycardia, and fetal and maternal death, especially with dosages >25 mcg.1 237 Risk of uterine rupture increases with advancing gestational age, prior uterine surgery (including cesarean delivery), and grand multiparity.1 237 Intravaginal use is not recommended in patients with a previous cesarean delivery or prior major uterine surgery.237

General Precautions

GI Effects

Possible diarrhea; 1 3 5 15 22 23 55 56 57 58 59 61 64 76 78 79 80 81 84 85 86 89 91 92 93 121 151 usually apparent after about 2 weeks of therapy.1 Generally is self-limiting,1 58 61 78 80 85 89 resolving within about a week after onset.1 61 Possible increased risk of profound (e.g., voluminous, watery) and life-threatening diarrhea in patients with inflammatory bowel disease.1 151 Use with extreme caution in these patients; careful monitoring recommended.1 151 Careful monitoring recommended in patients prone to dehydration or in whom its consequences would be dangerous.1 Administer in divided doses after meals and at bedtime;1 3 avoid concomitant administration with a magnesium-containing or other laxative antacid to minimize diarrhea.1

Cardiovascular Effects

Chest pain, edema, diaphoresis, hypotension, hypertension, arrhythmia, phlebitis, increased serum concentrations of cardiac enzymes, syncope, MI (some fatal), and thromboembolic events (e.g., pulmonary embolism, arterial thrombosis, cerebrovascular accident) reported; causal relationship to drug not established.1 Use with caution in patients with preexisting cardiovascular disease.1

Specific Populations

Pregnancy

Risk of serious fetal harm.1 (See Boxed Warning.)

Serious, sometimes fatal, bacterial (e.g., Clostridium sordellii) infection and sepsis or prolonged heavy vaginal bleeding reported following spontaneous, surgical, and medical abortions, including in patients receiving misoprostol with mifepristone for termination of pregnancy; causal relationship to regimen not established.241 242

Lactation

Misoprostol is metabolized rapidly to the free acid following oral administration, which is biologically active and distributed into breast milk.1 No published reports of adverse effects associated with misoprostol in breast-fed infants.1 Caution is advised if used during breast-feeding. 1
