RESULTS
Although the loss of smell and taste, which can sometimes be the first symptom in Covid-19, is stimulating, it is an extremely disturbing situation for patients. In our study, when we examined the drug use histories of 211 patients we followed up, we found that 26 patients had been using nasal steroids for a long time. The fact that none of these patients developed a decrease or loss of sense of smell suggested that nasal steroids may have a preventive effect on the loss of smell in Covid-19 patients. We believe that the loss of smell due to Covid-19 can be prevented by nasal steroid administration, which was presented to the literature for the first time through our study. However, in order to reach a definite conclusion, there is a need for randomized studies in which larger series and objective smell tests are applied.
