What drug treats acetaminophen toxicity?
Acetaminophen Toxicity Treatment The majority of patients survive acetaminophen toxicity with supportive care such as intravenous fluids and anti-nausea medication, activated charcoal, if used within one hour after ingestion, and antidotal therapy, including N-acetylcysteine (Acetadote®, Mucomyst®).
