AIDS and respiratory insufficiency were the side effects that led to treatment discontinuation most frequently in patients with refractory oropharyngeal candidiasis. Side effects were more frequent in patients with refractory oropharyngeal candidiasis. Serious side effects were reported in 55% in highly immunocompromised patients with advanced HIV disease. Fever and neutropenia were the serious side effects reported most often in these patients.
