Study suggests nasal spray azelastine may reduce COVID-19 risk by 67% in healthy adults.
A recent study published in JAMA Internal Medicine suggests that an over-the-counter nasal spray, azelastine, used for seasonal allergies, may significantly reduce the risk of COVID-19 infections.
The trial, conducted by German researchers on 450 healthy adults, showed a 67% reduction in infections among those using the spray three times daily.
While the study indicates fewer respiratory infections in the spray group, further research is needed due to the small sample size and other limitations.
