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 excessive medication, is swallowed. Immediate and appropriate response is vital to protect the airway and limit systemic absorption of the toxin. Knowing what not to do—such as avoiding induced vomiting—is just as essential as contacting emergency services.

Quick Summary

Immediately check airway and responsiveness, call Poison Control or emergency services, and never induce vomiting or administer fluids without professional medical direction.

Step-by-Step Guide

1

Assess Responsiveness and Call Emergency Services if Severe

Check whether the person is conscious, alert, and breathing comfortably. If they are unresponsive, having a seizure, struggling to breathe, or cannot be awakened, call 911 or your local emergency number immediately. If the person has no pulse and is not breathing, initiate cardiopulmonary resuscitation (CPR) without delay.

Important: Do not wait for symptoms to develop before calling for emergency help if you know a toxic substance was consumed.

2

Safely Clear Residual Substance from the Mouth

If the individual is conscious, instruct them to spit out any remaining solid material, such as tablets, capsules, or plant matter. You may wrap a clean, damp cloth around your finger to gently sweep visible solids out of their mouth. Never reach deep into the throat, as this can trigger a gag reflex or force objects down into the airway.

3

Do Not Induce Vomiting or Use Emetics

Never attempt to make the person vomit using salt water, manual gagging, or syrup of ipecac. If corrosive agents like strong acids, drain cleaners, or petroleum distillates were swallowed, regurgitating them causes a second wave of severe chemical burns to the esophagus and pharynx. Furthermore, vomiting significantly increases the danger of aspirating toxins into the lungs.

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

4

Contact Poison Control Immediately

In the United States, call Poison Help at 1-800-222-1222 to connect directly with specialized toxicologists and nurses, or contact your regional poison information center. Be ready to provide the person's approximate age, weight, symptoms, and medical history. Poison specialists will give you precise, substance-specific instructions on whether emergency department transport is necessary.

5

Identify and Preserve the Substance Container

Locate the product bottle, pill container, blister pack, or plant sample responsible for the ingestion. Keep the original packaging intact so you can read the active ingredients, concentration, and brand name directly to the poison specialist. When emergency medical services arrive or if you go to the hospital, bring the container and any vomited material with you.

6

Withhold Fluids and Home Remedies

Do not administer milk, water, raw eggs, or activated charcoal unless specifically directed by the poison control center. Giving liquids can cause the stomach to empty more quickly into the small intestine, accelerating systemic absorption, or trigger unexpected vomiting. Over-the-counter charcoal should never be given at home due to severe choking and aspiration risks.

7

Place the Person in the Recovery Position if Drowsy

If the person is breathing but becomes lethargic, drowsy, or nauseated, roll them onto their left side in the recovery position. Bend their top leg at the knee to stabilize their torso and gently tilt their head back to keep the airway open. This posture keeps the tongue from obstructing the throat and prevents accidental inhalation of vomit.

Important: Never leave a drowsy or intoxicated person lying flat on their back.

Frequently Asked Questions

Why is it dangerous to induce vomiting after someone swallows poison?
Vomiting can cause corrosive chemicals to burn the esophagus, mouth, and vocal cords a second time. It also carries a high risk of pulmonary aspiration, where the acidic or toxic stomach contents enter the lungs, causing severe chemical pneumonitis or asphyxiation.
When should I call 911 instead of Poison Control?
Call 911 immediately if the person is unconscious, has difficulty breathing, is actively seizing, or is exhibiting chest pain or severe agitation. If the person is alert, breathing normally, and stable, call Poison Control first at 1-800-222-1222 for tailored advice.
Can I give milk or water to dilute the swallowed chemical?
No. Dilution is rarely clinically helpful and can actually stimulate nausea and vomiting. In some cases, adding fluid accelerates the movement of the poison from the stomach into the intestines, speeding up its absorption into the bloodstream.
Should I keep activated charcoal at home for poison emergencies?
No. Routine home use of activated charcoal is not recommended by toxicology organizations. It does not bind to all substances (such as alcohols, lithium, or corrosives) and carries a substantial risk of entering the lungs if the patient gags or loses consciousness.
