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.
