First Aid for Poison Ingestion

Published: October 19, 2026Updated: October 19, 2026

Poison ingestion occurs when a harmful substance—such as household chemicals, toxic plants, or excess medication—is swallowed. Immediate and appropriate action is critical to prevent severe tissue injury, organ damage, or life-threatening systemic toxicity. Knowing what to do, and equally what not to do, helps protect the airway and prevents accidental harm while professional help is contacted.

Quick Summary

If someone ingests a poisonous substance, call emergency services or Poison Control immediately and never induce vomiting or administer fluids without expert guidance.

Step-by-Step Guide

1

Assess Responsiveness and Call Emergency Services

Quickly check if the person is awake, breathing, and responsive. If the person has collapsed, is having seizures, is unresponsive, or is struggling to breathe, call 911 or your local emergency number immediately. Begin cardiopulmonary resuscitation (CPR) if the person is not breathing and has no pulse.

Important: Do not wait for symptoms to appear or worsen before calling emergency services if the person is unresponsive or having convulsions.

2

Contact Poison Control

If the individual is conscious, alert, and not in immediate distress, call the national Poison Help line (1-800-222-1222 in the United States) or contact your regional poison center. Certified poison specialists will guide you through tailored, step-by-step instructions based on the specific toxin involved.

3

Identify the Ingested Substance

Locate the product bottle, medication blister pack, plant, or chemical container involved and keep it within arm's reach. Try to determine the exact product name, active ingredients, estimated quantity consumed, and the approximate time of ingestion so you can relay this to medical professionals.

Important: Do not taste or smell the substance to determine what it is, as this can expose you to harmful vapors or toxins.

4

Clear Remaining Residue from the Mouth

If fragments of pills, berries, or solid chemicals are still visible in the mouth, encourage the person to spit them out. For a child, gently wipe the inside of their mouth with a clean, damp cloth while avoiding pushing anything further down the throat.

5

Do Not Induce Vomiting

Never administer syrup of ipecac, salt water, or stick fingers down the throat to force vomiting. Caustic chemicals like bleach, acids, and drain openers cause secondary burns to the esophagus and pharynx upon re-exposure, and vomiting significantly elevates the risk of chemical aspiration into the lungs.

Important: Never induce vomiting unless explicitly commanded to do so by a certified poison control specialist or physician.

6

Place Unconscious Breathing Individuals in Recovery Position

If the individual is breathing normally but appears drowsy, confused, or loses consciousness, turn them gently onto their side in the recovery position. This posture prevents the tongue from blocking the airway and reduces the danger of choking if spontaneous vomiting occurs.

7

Hold Fluids and Home Remedies Unless Directed

Avoid giving the person milk, citrus juices, activated charcoal, or large quantities of water unless specifically directed by emergency dispatch or poison control. Neutralizing caustic agents with home acids or bases can trigger chemical heat reactions, compounding internal tissue damage.

Important: Do not give any liquids or food to someone who is drowsy, vomiting, or convulsing, as this creates a severe choking hazard.

Frequently Asked Questions

Should I induce vomiting if a child swallows a household cleaner?
No. Never induce vomiting after chemical ingestion. Caustic substances like bleach, oven cleaners, and toilet bowl cleaners will re-burn the esophagus, throat, and mouth on the way back up and can be aspirated into the lungs.
When should I give milk or water to dilute a swallowed toxin?
Only give small sips of water or milk if a poison specialist or emergency dispatcher explicitly instructs you to do so. In many cases, adding liquid can speed up absorption in the stomach or trigger nausea and vomiting.
Is syrup of ipecac still used as a first aid treatment?
No. Medical organizations, including the American Academy of Pediatrics, advise against using syrup of ipecac. It has not been shown to improve clinical outcomes and can cause severe complications, dehydration, and airway compromise.
What information should I have ready when calling Poison Control?
Be prepared to provide the person's age, weight, any pre-existing health conditions, the exact product container, how much was swallowed, when the ingestion occurred, and any current symptoms.
