Allergy spray could tame COVID symptoms, early trial hopes

NCT ID NCT06008860

First seen Jun 27, 2026 ยท Last updated Jun 27, 2026

Summary

This study tests whether Astepro, an over-the-counter allergy nasal spray, can help manage early COVID-19 symptoms and reduce viral load. 280 adults with a positive COVID test will use the spray or a placebo for 10 days. Researchers will track symptoms, viral levels, and whether the spray lowers infection rates in close contacts.

What this could mean

Our plain-language read of the trial. This is informational only โ€” not medical advice or a prediction.

Active substance
Astepro (azelastine) nasal spray
What this could lead to
If it works, this could offer a simple, over-the-counter nasal spray to reduce COVID-19 symptoms and possibly lower spread to close contacts.
What could go wrong
This is a small pilot study, not a large-scale trial. The spray is an antihistamine, not a direct antiviral, so it may not significantly affect the virus or symptoms.
