A new study reveals that azelastine nasal spray, an over-the-counter allergy medication, significantly reduces the risk of COVID-19 infection by approximately 67%. Participants in the study who used the spray experienced lower infection rates, milder symptoms, and shorter illness durations. While not a replacement for vaccines or masks, it offers an additional layer of protection during high-risk situations.
