Do this now

  1. If your child isn’t breathing, can’t be woken or is seizing, call 911.
  2. Otherwise, call 1-800-222-1222.
  3. Keep the medicine bottle in your hand so you can read the name and strength.
  4. Don’t try to make your child vomit, and don’t give anything else unless the poison center tells you to.

What they’ll ask

Why it matters even if your child seems fine

Some overdoses, including acetaminophen (Tylenol), may not cause symptoms right away, and treatment works best when it starts early. The poison center will tell you whether your child can be watched at home or needs to be seen.

Preventing the next one

Common questions

I gave my baby too much Tylenol. What do I do?

Call Poison Help at 1-800-222-1222 now, even if your baby seems fine. Acetaminophen overdose may not cause symptoms at first, and early treatment matters.

I gave a double dose by mistake. Should I skip the next one?

Call Poison Help first and follow their advice. Don’t try to balance it out on your own.

Should I make my child throw up?

No. Don’t try to make your child vomit unless a poison expert tells you to.
