Is intranasal corticosteroid treatment recommended for patients with COVID-19 that present with loss of smell?
A considerable percentage of COVID-19 patients experience loss of smell as an early sign of the disease. 94 In many patients smell recovers in 1-2 weeks and there is no indication that intranasal corticosteroid treatment has a positive impact on the recovery.122 On the other hand, there is no evidence suggesting that this treatment has a negative impact on symptomatology and/or development of COVID-19. Consequently, it is recommended to continue regular intranasal corticosteroid treatment for chronic rhinosinusitis.108,116
