Аннотация
BACKGROUND: Clostridium difficile infection is a leading healthcare-associated infection, and fidaxomicin is recommended as a first-line treatment. Although generally well-tolerated, post-marketing surveillance of fidaxomicin's safety profile is necessary given its increased utilization.
RESEARCH DESIGN AND METHODS: This study utilized the FDA Adverse Event Reporting System to analyze adverse drug reactions potentially linked to fidaxomicin use from January 2011 to June 2024. Data were extracted on patient demographics, reported ADRs, and outcomes. Descriptive statistics were used to analyze the ADR reports.
RESULTS: A total of 1,187 reports of ADRs were analyzed, including 122 deaths (10.3%), 187 hospitalizations (15.8%), and 17 disabilities (1.4%). The most commonly reported ADRs were gastrointestinal (33%) in nature. Neurological ADRs accounted for 6% of reports, with dizziness and headache being the most prevalent. Psychiatric ADRs such as insomnia and anxiety were reported in 2.8% of cases, with more than half considered serious. Cardiovascular ADRs, though infrequent (2.2%), were largely severe, with heart failure and arrhythmias being the most common.
CONCLUSION: While fidaxomicin is generally well-tolerated, our study identified rare but serious neuropsychiatric and cardiovascular ADRs. Further research is needed to investigate these effects and ensure informed, shared decision-making between prescribers and patients.
