Metro Manila (CNN Philippines, September 13) — Regulators are reviewing registered nasal spray products over reports that some brands claim to prevent COVID-19 infection.

"Currently we are still looking the whole database on all the registered/notified nasal spray and from there we could see which will be part of this review. We cannot say at this time if it is purely misleading claims or on the marketing of the product," the Food and Drug Administration (FDA) told CNN Philippines Monday.

In an advisory on Sept. 10, the FDA reminded the public that nasal spray products "do not have active pharmaceutical ingredients that directly treat, eliminate or prevent diseases."

"This should not be used as substitutes to medicines and vaccines to prevent or treat SARS-CoV2 Infection or COVID," the FDA said.

In a separate advisory, the Philippine Society of Otolaryngology reiterated FDA's statement and explained that while "commercially available nasal sprays with barrier protective effects may have a role in the mucosal defense against pathogens and contaminants," it is not a substitute for medicines and vaccines to prevent and treat COVID-19 infection.
