Ipilimumab can result in severe and fatal immune-mediated adverse reactions. Reactions may involve any organ system and manifest during treatment or weeks to months after discontinuation. The most common severe reactions are enterocolitis, hepatitis, dermatitis (including toxic epidermal necrolysis), neuropathy, and endocrinopathy. Assess patients for signs and symptoms of severe reactions and evaluate clinical chemistries (eg, liver function tests, adrenocorticotropic hormone levels, thyroid function tests) at baseline and before each dose. Permanently discontinue ipilimumab and initiate systemic high-dose corticosteroid therapy for severe immune-mediated reactions .
