The application of Nasacort, for the sinus infection caused the loss of taste and smell after the first dose. The side effects described in the Nasacort prescribtion don't include the loss of smell and taste but the web page of Nasacort. I stopped applying Nasacort immediately, however I have not gained the smell and taste capability for two days. Do you have any info how long it takes to regain the smell ande taste functions?
