Safety of high-dose micafungin for patients with hematological diseases

Abstract

This study was conducted as a retrospective, observational, exploratory cohort study with the aim of elucidating the safety profile of micafungin at doses exceeding 150 mg daily. We identified adult patients with hematological diseases who had received micafungin therapy for ≥ 7 consecutive days. Twenty-six patients administered micafungin at 300 mg daily (high-dose group) were compared with 58 patients administered micafungin at 150 mg daily (standard-dose group). The most frequent adverse events (AEs) were hepatotoxicity, hypertension and diarrhea. AEs were recorded in 42 (72%) and 19 (73%) patients in the standard-dose and high-dose groups, respectively (p = 1.00). Hepatobiliary AEs were noted in 28 (48%) and 15 (58%) patients, respectively (p = 0.48). Serious AEs and resultant treatment discontinuation were infrequent. Our results suggest that micafungin was safe and well tolerated at 300 mg daily.
