Does an inhaled corticosteroid such as flovent help with asthma and covid-19?

Corticosteroids are felt to mitigate the inflammatory reactions seen in covid infections, but this refers to larger doses of systemically administered ones, not those delivered by nasal spray. However if asthmatic reactions are occurring nasal corticosteroids as well as bronchodilating nasal sprays will still be used as needed.

Continue your usual asthma plan, and steroids for control of your asthma may be increased as needed to maintain asthma control during the COVID 19 infection. Asthmatic patients without COPD tend to have no increased risk of COVID progression. Watch for signs of shortness of breath, worsening cough and chest pain.
