The management of amatoxin poisoning consists of preliminary medical care, supportive measures, detoxification therapies, and orthotopic liver transplantation. Liver damage from Amanita phalloides is related to the amanitins, powerful toxins that inhibit RNA polymerase II resulting in a deficient protein synthesis and cell necrosis. Chi-square statistical comparison of survivors and dead vs. treated individuals supported silybin, administered either as mono-chemotherapy or in drug combination and N-acetylcysteine as mono-chemotherapy as the most effective therapeutic modes.

Eventually shell suffer from abdominal cramps, vomiting, and severely dehydrating diarrhea.

As a potential treatment for amatoxin poisoning, N-acetylcysteine (NAC) has been used for decades but its benefit is still unproven.
