✔ Oral Poisoning Cases (ONLY if immediate hospital care is unavailable)
✔ Drug Overdose (Certain cases where activated charcoal is not available)
✔ Accidental poisoning in remote settings (with medical advice)
🚨 Rarely Used Today!
🔹 Now replaced by activated charcoal and gastric lavage as the preferred methods.

🚫 Petroleum & Hydrocarbon Poisoning (Kerosene, Gasoline, Paint Thinners) – Risk of aspiration pneumonitis
🚫 Altered Consciousness (Unconscious, Drowsy, Seizures) – Risk of aspiration
🚫 Poisoning with Rapid CNS Depressants (Opioids, Benzodiazepines, Alcohol, Barbiturates) – Vomiting can worsen airway obstruction
🚫 Ingested Poisons More than 1 Hour Ago – Most toxins are already absorbed, making ipecac ineffective
🚫 With Activated Charcoal:
🚫 With CNS Depressants (Opioids, Benzodiazepines, Alcohol):
🚫 With Cardiotoxic Drugs (Digoxin, Beta-blockers, Calcium Channel Blockers):
⚠ Common Side Effects:

2️⃣ Provide IV Fluids & Electrolyte Replacement
3️⃣ Administer Activated Charcoal (If Ipecac was ingested recently)
4️⃣ Treat Arrhythmias (If Emetine toxicity occurs, give Beta-blockers)
5️⃣ Oxygen & Ventilatory Support (If Aspiration occurs)
👩⚕️ Pre-Administration Check:
✔ Confirm time of poisoning (If >1 hour, Ipecac is NOT effective).
✔ Assess patient’s consciousness level (Do NOT give if unconscious).
✔ Identify type of poison (Ipecac is contraindicated in corrosives & hydrocarbons).
💉 Administration Guidelines:
✔ Give Ipecac on an empty stomach (For best emetic effect).
✔ Follow with 1-2 glasses of water to improve absorption.
✔ DO NOT give with activated charcoal (Reduces effectiveness).
🩺 Monitoring:
✔ Observe for onset of vomiting within 30 minutes.
