Evaluation of Drug-Drug Interactions in Patients Admitting to the Ear Nose and Throat Clinic

Introduction: Drug interactions are effects that change the effect of the drug and therefore on the patient, mostly due to the use of drugs together at the same or recent times. Drug interactions can cause serious consequences such as the development of adverse events, ineffectiveness of the treatment, or mortality. Materials and Methods: The prescriptions of 106 patients who applied to the ear, nose, and throat outpatient clinic between January and December 2021 were examined retrospectively. Results: 106 prescriptions were included in the study. Twelve major, 19 moderate, and 9 minor interactions were detected in 106 prescriptions. Conclusion: Although there are relatively few interactions compared to studies conducted with other patient groups, interactions can affect the clinical status of the patient. More attention should be paid to drug interactions in these patients, especially physicians and pharmacists.
