Overview
Brief Summary
The study will be a randomized controlled trial, involving patients with hyposmia/anosmia of onset immediately after an upper respiratory viral illness, assigned to three distinct study arms. Nasal irrigations will be prescribed to all three groups (BID). In addition, one arm will receive a paper hand-out about post-viral anosmia with instructions to smell common household items (current care) and act as a control group. The second group will receive an essential oil retraining kit, whereas the third group will receive the same olfactory training kit and a prescription to use budesonide with the nasal irrigations. Olfactory scores will be tested at the enrollment, 3 months and at 6 months.
