Acute poisoning is a common medical emergency that can affect individuals of all ages and backgrounds. While many poisoning cases are seen in emergency departments, primary care settings are often the first point of contact, especially in communities with limited access to specialized care.
Neftaly’s Acute Care Protocol for poisoning management in primary care equips clinicians with a clear, safe, and structured approach to identify, stabilize, and refer patients suffering from acute toxic exposures. Early recognition and intervention can be lifesaving.
1. Objectives of Poisoning Management in Primary Care
- Rapid assessment and stabilization of the patient
- Identification of the type and severity of poisoning
- Initiation of essential decontamination or antidotal therapy if indicated
- Safe triage and timely referral or transfer to emergency care
- Counseling for prevention and follow-up
2. Common Causes of Acute Poisoning
In Children:
- Accidental ingestion of medications (e.g., analgesics, vitamins, iron)
- Household chemicals (e.g., bleach, cleaners)
- Plants or cosmetics
In Adults:
- Intentional overdose (e.g., psychiatric medications, opioids, sedatives)
- Alcohol or recreational drugs
- Occupational or environmental exposure
- Food poisoning or contaminated substances
3. Initial Assessment (First 5 Minutes)
A – Airway
- Ensure airway is patent
- Protect cervical spine if trauma is suspected
B – Breathing
- Assess respiratory rate and oxygen saturation
- Provide oxygen if needed
C – Circulation
- Monitor blood pressure, heart rate, perfusion
- Establish IV access if available
D – Disability
- Check level of consciousness (AVPU or GCS)
- Assess for seizures or agitation
E – Exposure
- Remove contaminated clothing
- Look for signs of trauma, rash, burns
⚠️ Neftaly Red Flag: If unstable vitals, decreased consciousness, or seizures—immediate transfer to emergency care is necessary.
4. Focused History (SAMPLE)
| SAMPLE | Questions to Ask |
|---|---|
| S – Signs/Symptoms | What are the current symptoms? Vomiting? Confusion? Seizures? |
| A – Allergies | Any known drug allergies? |
| M – Medications | What substances were taken? What dose? Any other medications? |
| P – Past medical history | Any psychiatric illnesses, chronic diseases? |
| L – Last intake | When was the exposure or ingestion? Last meal? |
| E – Events | Was it intentional or accidental? Where and how did it happen? |
5. Identify Toxidromes (Syndrome-Based Diagnosis)
| Toxidrome | Key Features | Examples |
|---|---|---|
| Anticholinergic | Dry skin, dilated pupils, tachycardia, delirium | Antihistamines, TCAs |
| Cholinergic | Salivation, lacrimation, diarrhea, bradycardia | Organophosphates, pesticides |
| Opioid | Pinpoint pupils, respiratory depression, sedation | Heroin, morphine |
| Sympathomimetic | Agitation, tachycardia, hypertension, dilated pupils | Cocaine, amphetamines |
| Sedative-Hypnotic | Slurred speech, ataxia, CNS depression | Benzodiazepines, alcohol |
6. Decontamination (If Applicable and Safe)
| Method | When to Use |
|---|---|
| Activated Charcoal | Within 1 hour of ingestion; if airway protected |
| Skin Decontamination | For dermal exposure; use soap and water |
| Eye Irrigation | Chemical in eyes; flush with normal saline |
| Do NOT induce vomiting | Ipecac is no longer recommended |
7. Antidotes (Common Examples in Primary Care)
| Substance | Antidote |
|---|---|
| Paracetamol (acetaminophen) | N-acetylcysteine (NAC) |
| Opioids | Naloxone (Narcan) |
| Benzodiazepines | Flumazenil (use cautiously) |
| Organophosphates | Atropine + Pralidoxime |
| Iron overdose | Deferoxamine |
Always consult a poison center or toxicologist before administering antidotes in uncertain cases.
8. Criteria for Immediate Referral or Transfer
- Unconscious or rapidly deteriorating patient
- Seizures or severe agitation
- Airway compromise or hypoxia
- Suspected ingestion of life-threatening substances (e.g., TCA, cyanide, methanol)
- Pediatric ingestion with uncertain quantity
- Multi-drug overdose or polypharmacy cases
- Non-accidental or suicidal poisoning (requires psychiatric evaluation)
9. Documentation and Legal Considerations
- Document substance, quantity, timing, symptoms, and treatment clearly
- Record communication with poison control or emergency services
- If intentional or abuse suspected, follow local reporting protocols
- Preserve containers, pill bottles, or vomitus for identification
10. Patient and Family Education
If managing minor poisoning in the clinic:
- Counsel on safe storage of medicines and chemicals
- Provide clear discharge instructions on symptoms to watch for
- Ensure family knows when and where to seek emergency care
- Offer referral for mental health support if intentional poisoning
11. Poison Control Resources
Ensure access to your local or national poison control center. Examples:
- South Africa: Poisons Information Helpline – 0861 555 777
- United States: Poison Help – 1-800-222-1222
- UK: National Poisons Information Service (via TOXBASE)
Neftaly Primary Care Action Checklist for Acute Poisoning
✅ Airway, breathing, circulation check

Conclusion
With early recognition and structured management, primary care providers can play a vital role in saving lives during acute poisoning episodes. Neftaly’s Acute Care Protocol empowers frontline clinicians to deliver safe, efficient, and coordinated care—even before hospital transfer.
