Cytotec 200mcg (misoprostol) is a synthetic prostaglandin E1 analog available in 200 mcg tablets (among other strengths). Here’s a concise overview based on established medical sources like FDA labeling, WHO guidelines, and pharmacology references:

Primary Approved Uses (US FDA)

• Gastroprotection: Prevents NSAID-induced gastric ulcers in high-risk patients (e.g., 200 mcg orally 4x daily with meals and at bedtime).
• Postpartum hemorrhage: 600–1,000 mcg rectally (off-label in some regions but WHO-recommended).

Common Off-Label/International Uses

• Medical abortion (with mifepristone): 800 mcg (4x 200 mcg) vaginally or buccally, typically 24–48 hours after mifepristone. Efficacy ~95% for pregnancies <10 weeks (per ACOG/WHO data).
• Labor induction/cervical ripening: 25–50 mcg vaginally every 4–6 hours (monitored setting).
• Miscarriage management: 800 mcg vaginally/sub lingually.

Mechanism

Binds EP receptors → increases cervical tone, uterine contractions, and protects gastric mucosa by ↑ mucus/bicarbonate and ↓ acid.

Side Effects (Dose-Dependent)

• Common: Diarrhea (20–40%), abdominal pain, nausea, vomiting, fever/chills.
• Serious: Uterine hyperstimulation (fetal distress if pregnant), heavy bleeding, allergic reactions.
