Is poisoning by nm substances an emergency?

Whether a poisoning is an emergency depends on the substance, the amount, and how the person is responding. Some exposures are life-threatening within minutes; others can be safely monitored at home with expert guidance. The signs below tell you which situation you are in.

Call 911 Immediately If

These signs mean the poisoning is a true emergency that needs an ambulance, not a car ride:

• The person is unconscious or hard to wake
• Trouble breathing, choking, or noisy or stopped breathing
• A seizure or convulsions
• Chest pain or a very irregular heartbeat
• Severe confusion, extreme drowsiness, or unresponsiveness
• Signs of a severe allergic reaction: swelling of the face, lips, or throat

Do not wait to see if things improve. While you wait for help, keep the person on their side if they are drowsy or vomiting so they do not choke.

What Makes a Poisoning an Emergency

Certain exposures are dangerous even before dramatic symptoms appear, and they warrant emergency care:

• Carbon monoxide — suspect it when several people or pets in the same home have headache, dizziness, and nausea at once. You cannot see or smell it. Get everyone into fresh air and call 911.
• Corrosive chemicals — drain cleaner, bleach, oven cleaner, or strong acids can burn the mouth, throat, and esophagus. Do not induce vomiting.
• Antifreeze, windshield washer fluid, or methanol — these can look and taste harmless but cause organ damage hours later.
• Pesticides or industrial chemicals — drooling, muscle twitching, blurred vision, and vomiting can signal serious toxicity.
• A large amount of alcohol, or an unknown substance swallowed by a child.

An important rule: never make the person vomit unless Poison Control or a physician tells you to.

When It May Not Be an Emergency

If the exposed person is fully awake, breathing normally, and has no or only mild symptoms, call Poison Control at 1-800-222-1222 first. This free line is staffed 24/7 by toxicology experts who can tell you whether home monitoring is safe or whether you need to be seen. A small taste of a low-toxicity product or a minor skin contact that is rinsed off promptly can often be managed at home under their guidance. When in doubt — especially with a child or an unknown substance — err toward an in-person evaluation.
