Adverse events associated with teriparatide: a real-world disproportionality analysis of the FDA adverse event reporting system (FAERS)

BACKGROUND: Teriparatide is widely used for osteoporosis treatment in various patients, but its safety profile is not fully documented. This study analyzes the FDA pharmacovigilance database to assess teriparatide's safety. RESEARCH DESIGN AND METHODS: Data from the first quarter (Q1) of 2004 to the third quarter (Q3) of 2023 were extracted and analyzed for disproportionality between teriparatide and adverse effects (AE). RESULTS: = 54,474). Teriparatide revealed a marked association with an increased propensity for musculoskeletal and connective tissue disorders (ROR,3.95; 95% CI, 3.91-3.99) at the System Organ Class (SOC) level. Concurrently, 199 preferred terms (PTs) displayed significant disproportionality across all four employed algorithms. CONCLUSIONS: Our study confirms several well-known adverse drug reactions and identifies potential safety issues associated with teriparatide treatment. This contributes to a deeper understanding of the complex relationship between adverse reactions and teriparatide. These findings emphasize the importance of continuous monitoring and ongoing surveillance to promptly identify and effectively manage adverse reactions, thereby enhancing overall patient safety and well-being.
