When should I go to the ER for poisoning by nm substances?
Go to the ER or call 911 for poisoning when the person is unconscious, seizing, has trouble breathing, chest pain, or swallowed a corrosive or unknown amount. If they are awake and stable, call Poison Control at 1-800-222-1222 first — they will tell you whether an ER visit is needed.
With most poisonings, the first call is not to the ER — it is to Poison Control at 1-800-222-1222, a free 24/7 line staffed by toxicology experts. They can direct you to the right level of care. The exception is any life-threatening sign, which means calling 911 right away. Here is how to decide.
Call 911 — Do Not Drive
Call for an ambulance if the poisoned person is unconscious, seizing, not breathing normally, having severe trouble breathing, or having chest pain. Also call 911 for suspected carbon monoxide — when several people or pets in the same building have headache, dizziness, and nausea together — after getting everyone into fresh air. These situations can worsen fast, and paramedics can begin treatment on the way.
Go to the ER
Come to the ER (or let Poison Control direct you there) when the person is awake but:
- Swallowed a corrosive — drain cleaner, bleach, oven cleaner, or a strong acid
- Was exposed to antifreeze, methanol, or an industrial chemical
- Took an unknown substance or an unknown amount, especially a child
- Has worsening or persistent symptoms — repeated vomiting, breathing trouble, confusion, or burns
- Is very young, elderly, pregnant, or has serious underlying health conditions
Bring the product container or a photo of the label so the physician can identify the toxin quickly.
When Poison Control, Telemedicine, or Urgent Care Is Reasonable
For a known, low-risk exposure in someone who is fully awake and breathing normally, Poison Control often advises safe home monitoring — for example, a small taste of a low-toxicity household product or a minor skin contact rinsed off promptly. Telemedicine or urgent care can handle follow-up questions or mild, stable symptoms after a low-risk exposure. But urgent care lacks the tools for a serious poisoning; when the substance, amount, or symptoms are uncertain, an ER visit is the safer choice.
