How do I care for someone with Tylenol (acetaminophen) poisoning?

If you suspect someone may have taken a large enough overdose of acetaminophen to cause poisoning, you should contact a doctor or your local poison control center immediately, even if the person says they feel fine; symptoms sometimes take over 24 hours to appear. You can help the doctor assess the severity of the poisoning by providing information about the type and amount of medication your loved one has ingested, and an estimation of the time it was taken. Remember that early detection and treatment can often prevent hospitalization, liver damage, and even death that may occur if the overdose is left untreated.
