Neonates face heightened susceptibility to drug toxicity, often exposed to off-labelmedications with dosages extrapolated from adult or pediatric studies. Premature infants in NeonatalIntensive Care Units (NICUs) are particularly at risk due to underdeveloped pharmacokinetics andexposure to multiple drugs. The study aimed to survey commonly used medications with a higher risk ofototoxicity and nephrotoxicity in Spanish and Italian NICUs.Methods. A prospective cross-sectional study was conducted in Italian and Spanish NICUs using a webbased survey with 43 questions. A modified Delphi method involved experts refining the survey throughonline consensus. Ethical approval was obtained, and responses were collected from January to July2023. The survey covered various aspects, including drug-related ototoxic and nephrotoxic management,hearing screening, and therapeutic drug monitoring.Results. Responses from 131 participants (35.9% from Spain and 64.1% from Italy) revealed awarenessof drug toxicity risks. Varied practices were observed in hearing screening protocols, and a highprevalence of ototoxic and nephrotoxic drug use, including aminoglycosides (100%), vancomycin(70.2%), loop diuretics (63.4%), and ibuprofen (62.6%). Discrepancies existed in guideline availability andadherence, with differences between Italy and Spain in therapeutic drug monitoring practices.Conclusions. The study underscores the need for clinical guidelines and uniform practices in managingototoxic and nephrotoxic drugs in NICUs. Awareness is high, but inconsistencies in practices indicate anecessity for standardization, including the implementation of therapeutic drug monitoring and theinvolvement of clinical pharmacologists. Addressing these issues is crucial for optimizing neonatal carein Southern Europe.
