Acute liver failure – Diagnosis and treatment – Mayo Clinic

Acute liver failure caused by acetaminophen overdose is treated with a medication called acetylcysteine. This medication may also help treat other causes of acute liver failure. Mushroom and other poisonings also may be treated with drugs that can reverse the effects of the toxin and may reduce liver damage.
