✅ Approved Indication:

Medical termination of intrauterine pregnancy up to 63 days (9 weeks) of gestation

• This is the only formally approved indication in most regulatory agencies (FDA, EMA, WHO).
• Standard regimen: Mifepristone 200 mg orally, followed 24–48 hours later by Misoprostol 800 mcg buccally, sublingually, or vaginally.

⚠️ Off-label / Guideline-Supported Indications

Although not part of official drug labeling, these uses are strongly supported by WHO (2022 Abortion Care Guideline), NICE (NG140), and other international bodies:

Termination of pregnancy beyond 9 weeks (2nd trimester, under hospital supervision)

• Used in certain cases; requires specialist monitoring due to higher risk of hemorrhage or incomplete abortion.

Management of missed abortion (missed miscarriage)

• When fetal death has occurred, but pregnancy tissue remains in the uterus.
• Medical management with Mifepristone + Misoprostol is an effective alternative to surgical evacuation.

Management of incomplete abortion

• Used to expel retained products of conception after spontaneous or induced abortion.

Induction of uterine evacuation in intrauterine fetal death (IUFD)

• For pregnancies where the fetus has died in utero, but labor has not started naturally.

Cervical ripening before surgical abortion

• Mifepristone softens the cervix, Misoprostol promotes uterine contractions, reducing surgical risk.

Labor induction in selected clinical scenarios

• Such as IUFD or when continuation of pregnancy is dangerous for maternal health.

📌 Summary:

• Approved: Medical abortion up to 9 weeks.
• Off-label (guideline-supported): Missed abortion, incomplete abortion, 2nd trimester termination, IUFD, cervical ripening, and selected cases of labor induction.

Important Notice
This medication must be taken only under the advice and supervision of a registered medical practitioner. Self-medication without proper medical consultation may be unsafe and can lead to serious health risks.

Step 1: Mifepristone

• Dose: 1 tablet (200 mg)
• How to take: Swallow whole with water
• Purpose: Stops the pregnancy from continuing by blocking progesterone
• Next step: Wait 24–48 hours before taking misoprostol

Step 2: Misoprostol

Total dose: 4 tablets (200 mcg each = 800 mcg)

Recommended method (Buccal)

1.        Place 2 tablets between the left cheek and gum

2.        Place 2 tablets between the right cheek and gum

3.        Hold in place for 30 minutes until dissolved

4.        Swallow any remaining pieces with water

What to Expect

• Onset: Cramping and bleeding usually begin 1–4 hours after misoprostol
• Peak effect: Strong cramps and heavier bleeding typically last 4–6 hours
• Completion: Most pregnancies pass within 24 hours, though lighter bleeding may continue for several days

  Common symptoms may include:

  a.        Abdominal cramping

  b.       Heavy bleeding with clots

  c.        Nausea or vomiting

  d.       Diarrhea

  e.        Chills or mild fever

When to Seek Medical Care

Seek immediate medical attention if you experience:

• Heavy bleeding: Soaking 2 or more large pads per hour for 2 consecutive hours
• High fever: Temperature above 38°C (100.4°F) starting 24 hours after the medication
• Severe pain: Intense abdominal pain not relieved by ibuprofen
• No bleeding: No bleeding within 24 hours after taking misoprostol.

Mifepristone is a competitive antagonist at progesterone receptors, interrupting progesterone-mediated support of the endometrium and leading to decidual breakdown. It also increases uterine contractility and cervical softening by sensitizing the myometrium to prostaglandins. Misoprostol, a prostaglandin E₁ analog, induces uterine contractions and cervix dilation, facilitating expulsion of uterine contents. This sequential action ensures complete termination or evacuation.

Absorption:

• Mifepristone is rapidly absorbed orally (peak 1–2 h).
• Misoprostol is absorbed via buccal/vaginal routes; buccal peaks at 1 h.

Distribution:

• Mifepristone highly protein‑bound (>98%), large volume of distribution.
• Misoprostol acid (active metabolite) moderately bound.

Metabolism:

• Mifepristone metabolized by CYP3A4 to active and inactive metabolites; half-life 18–25 h.
• Misoprostol is swiftly deesterified to its active form; half-life 20–40 minutes.

Excretion:

• Mifepristone and metabolites via biliary and renal routes.
• Misoprostol metabolites eliminated in urine.

Pregnancy:

• Contraindicated when used for abortion outside approved gestational age. Use category X as per FDA for pregnancy interruption (intended).

Lactation:

• Misoprostol and mifepristone may pass into breast milk in small amounts.
• Breastfeeding may continue after abortion, but express and discard milk for 36–48 h post-mifepristone to allow elimination.
• Caution advised due to theoretical risk of uterine side effects in the infant (rare).

• Primary class: Antiprogestin (mifepristone) + Prostaglandin analog (misoprostol).
• Subclass: Abortifacient/prostaglandin E₁ analog.

• Known allergy to mifepristone, misoprostol, or prostaglandin analogs.
• Ectopic pregnancy (ruptured or suspected).
• Chronic adrenal failure (due to mifepristone’s glucocorticoid antagonism).
• Simultaneous long‑term corticosteroid therapy.
• Hemorrhagic disorders or on anticoagulants with high bleeding risk.
• Severe anemia (Hb < 9 g/dL).
• Inability to access emergency medical care.

• High-risk groups: Anemic patients, adrenal insufficiency.
• Severe risk: Heavy bleeding (occurring in 5%), including hemorrhage.
• Monitoring: Confirm completion via ultrasound/hCG tests. Watch for infection, excessive bleeding, or sepsis.
• Early warning signs: Fever >38 °C, severe abdominal pain with dizziness, hypovolemia—requires urgent care.

Common (Systemic):

• GI upset: nausea, vomiting, diarrhea, abdominal cramps (around misoprostol dosing).
• Headache, dizziness, fatigue.

Gynecologic/Reproductive:

• Heavy uterine bleeding 24–48 h post-misoprostol; cramps moderate to severe during expulsion.
• Transient spotting up to 14 days.

Rare/Serious:

• Endometrial infection, sepsis (especially with fever >37.8 °C ≥ 24 h).
• Uterine rupture in late pregnancy use (very rare).
• Hypovolemic shock due to hemorrhage.

• CYP3A4 inducers (e.g., rifampin, carbamazepine, phenytoin): may reduce mifepristone levels → decreased efficacy.
• CYP3A4 inhibitors (e.g., ketoconazole, itraconazole): may increase mifepristone concentrations, raising risk of cortisol receptor antagonism/adrenal insufficiency.
• Anticoagulants/antiplatelets (e.g., warfarin): increased bleeding risk due to induced uterine bleeding.
• Alcohol: may exacerbate GI effects and dehydration—advise avoidance.

• WHO (2023): Expanded indication to ≤70 days; endorses home-based use up to 63 days.
• NICE (2024, UK): Confirms home use safe and effective for ≤10 weeks, with remote follow‑up via telehealth.
• FDA (2024): Approved buccal misoprostol route; clarified safety data.
• ACOG (2022): Recommends 200 mg mifepristone alternative (vs. 600 mg) with similar outcomes; adoption underway in some regions.

• Mifepristone tablets: Store at 20–25 °C (68–77 °F); brief excursions 15–30 °C allowed. Keep in original blister until use; protect from moisture and light.
• Misoprostol tablets: Store at ≤25 °C; tightly sealed in original container with desiccant to prevent humidity exposure; avoid freezing.
• Reconstitution not applicable. If any off-label compounding: refrigerate 2–8 °C and use within 14 days; discard if not used.
