Misoprostol 200 mcg (often written as 200 mg in some contexts, but the standard dosage unit is micrograms or mcg) is primarily used for the prevention and treatment of gastric ulcers, particularly those induced by nonsteroidal anti-inflammatory drugs (NSAIDs)[1]. It is also extensively used off-label in obstetrics and gynecology for various indications, including medical abortion, management of miscarriage, induction of labor, cervical ripening before procedures, and treatment of postpartum hemorrhage[3][5].
Common Medical Uses for Misoprostol 200 mcg:
- Prevention of NSAID-induced gastric ulcers: The standard adult dose for this indication is 200 mcg orally, four times daily, usually taken after meals and at bedtime for the duration of NSAID therapy[1][2][7].
- Treatment of gastric and duodenal ulcers: The same dosage regimen applies—200 mcg orally, four times a day after meals and at bedtime. If this dose is poorly tolerated, it may be reduced to 100 mcg[2].
Obstetric and Gynecologic Uses (off-label):
- Medical abortion: Misoprostol is used with mifepristone for termination of early intrauterine pregnancy. After taking 200 mg mifepristone orally, 800 mcg misoprostol (four 200 mcg tablets) is taken buccally (between the cheek and gum) 24–48 hours later[4][6]. In other protocols, dosing and administration route (oral, sublingual, vaginal) may vary[5].
- Management of miscarriage and missed abortion: Misoprostol helps expel uterine contents, often at doses of 800 mcg vaginally or orally, sometimes repeated after 24 to 48 hours if necessary[5].
- Induction of labor and cervical ripening: Vaginal, oral, or sublingual misoprostol (doses and timing vary by indication and protocol) is used to soften the cervix and induce uterine contractions[5].
- Treatment of postpartum hemorrhage: Misoprostol is used to stimulate uterine contractions and reduce bleeding, often at doses of 600–800 mcg by oral or sublingual route[5].
Mode of Administration: Misoprostol can be given orally, sublingually (under the tongue), buccally (between cheek and gums), or vaginally, depending on the indication and protocol[4][5]. Always follow a healthcare provider’s instructions for the specific medical use.
