Abstract

Abstract Background and objectives Fluoroquinolones are linked with increased risk of CNS adverse events, such as anxiety and depression. Recently, case reports have linked fluoroquinolone use and panic attacks. However, current evidence exploring the link between fluoroquinolone use and panic attacks remains limited and requires investigation for safe use. To systematically review the literature on fluoroquinolone use and the risk of panic attacks, and to study this association by comparing fluoroquinolones with other antibiotics using the FDA Adverse Event Reporting System (FAERS) database. Methods MEDLINE and Embase databases were searched to identify relevant studies for systematic review. Active-comparator restricted disproportionality analyses using FAERS (2004Q1-2024Q4) were performed for ciprofloxacin, levofloxacin, and moxifloxacin compared to azithromycin and trimethoprim/sulfamethoxazole. Reporting odds ratios (ROR), proportional reporting ratios, adjusted ROR for potential confounders, and Bayesian analyses were conducted to detect safety signals for MedDRA term ‘panic attack’. Results The systematic review identified 12 studies (4 clinical trials, 8 publications describing 11 case reports), with the prevalence of panic attacks ranging between 0.46% and 1.76% in trials. Disproportionality analysis showed that, compared to azithromycin, fluoroquinolones were associated with a 6-fold increase in reports of panic attacks and a 12-fold increase compared to…

How strong is the evidence?

Evidence Hub reads this as a systematic review, done in people. Its evidence level is 1 of 5 (Highest · pooled evidence). Pooled evidence from several studies sits at the top of the evidence pyramid.
