I lost my sense of smell after one use of nasal spray!

Help. Last night I used Otrivine -- only active ingredient is Xylometazoline (0.1%) -- once per each nostril and today I seem to have lost all sense of smell.  I have had a pretty bad cold for a week but I could still smell my baby’s diapers… but now I cannot, even though my nose is clear . There is no mention of this among the possible side effect. Will it reverse???? please help!
