Poison Ingestion First Aid

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

Poison ingestion occurs when a harmful substance—such as household chemicals, medications, plants, or toxins—is swallowed. Quick and calm action is essential to prevent severe injury or death. Knowing how to assess the person and contacting emergency poison services immediately can save lives.

Quick Summary

If someone swallows a poisonous substance, call emergency services or Poison Help immediately, do not induce vomiting, and preserve the substance container if safe to do so.

Step-by-Step Guide

1

Assess responsiveness and breathing

Check whether the person is conscious, alert, and breathing normally. If the person has collapsed, is having seizures, or is struggling to breathe, call emergency services (such as 911) immediately. If they are unresponsive and not breathing, begin cardiopulmonary resuscitation (CPR) without delay.

Important: Never delay calling emergency services if the person is unresponsive, having a seizure, or having difficulty breathing.

2

Clear any remaining substance from the mouth

If the person is conscious and cooperative, instruct them to spit out any remaining pills, plant fragments, or liquids. You may gently wipe out the inside of their mouth using a damp, clean cloth. Do not force fingers into the mouth of someone who is combative, drowsy, or having a seizure.

3

Call Poison Control or emergency services

In the United States, call Poison Help at 1-800-222-1222, or reach out to your local emergency medical dispatch center. Have critical details ready, including the person's age, approximate weight, suspected substance, estimated quantity ingested, time of ingestion, and any current symptoms. Carefully follow the specialist's exact instructions.

4

Do not induce vomiting or give unapproved home remedies

Never attempt to make the person throw up unless explicitly instructed to do so by a poison control specialist or physician. Regurgitating corrosive chemicals, caustics, or petroleum products can cause severe chemical burns to the esophagus and lead to dangerous pulmonary aspiration. Avoid administering raw eggs, milk, activated charcoal, or salt water.

Important: Inducing vomiting or administering unauthorized fluids can cause severe chemical burns to the esophagus and lungs.

5

Place an unconscious, breathing person in the recovery position

If the person is breathing but unresponsive or drowsy, gently turn them onto their side into the recovery position. This position prevents the tongue from blocking the airway and reduces the risk of choking if spontaneous vomiting occurs. Continue to monitor their breathing and consciousness closely until paramedics arrive.

6

Preserve the poison container and evidence

Safely collect the medicine bottle, chemical packaging, plant parts, or containers related to the incident and give them to arriving emergency responders. Having the exact product label allows clinicians to identify active ingredients, calculate toxic dosages, and administer targeted antidotes. Wash your hands thoroughly if you come into contact with chemical residue.

Frequently Asked Questions

Why is it dangerous to give milk or water to dilute swallowed poison?
Giving fluids can cause the stomach to empty more quickly into the small intestine, accelerating systemic absorption of toxins, or it may trigger vomiting that risks burning the airway. Only administer fluids if a poison control specialist specifically directs you to do so.
What should I do if a child swallows a button battery or magnet?
Button battery or magnet ingestion is a critical medical emergency requiring immediate evaluation at an emergency department. Button batteries can cause severe tissue necrosis and esophageal perforation within two hours, while multiple magnets can clamp intestinal walls together.
What information should I have ready when calling Poison Control?
Provide the person's age and weight, the product name or packaging details, the estimated amount swallowed, the time the ingestion occurred, any existing symptoms, and relevant medical history.
Should I use activated charcoal at home?
No. Activated charcoal should only be administered by trained medical professionals in a hospital setting. If given inappropriately, it carries a high risk of lung aspiration and is completely ineffective against many common toxins, including alcohols, metals, and corrosive acids.
