Paxlovid treats mild to moderate COVID-19 in adults. You must be at high risk of your illness becoming severe. This includes needing to go to the hospital or possibly dying from COVID-19. Paxlovid is not for preventing COVID-19 before or after exposure.
Qvar Redihaler contains beclomethasone, a type of corticosteroid. Corticosteroids reduce inflammation in the airways. This makes it easier to breathe and helps prevent asthma symptoms.

For these top-ranked reactions alone, beclomethasone has 0 submissions while nirmatrelvir/ritonavir has 56,802.
