Allergy Blocker Spray for Seasonal Nasal Allergies
Part of Ear, nose & throat, Immune system & allergy, Lungs & breathing clinical trials.
This trial tests whether PL-14, a new nasal spray, works better than saline spray at relieving seasonal allergy symptoms like sneezing, itching, and congestion. If it works well and is safe, it could offer patients a new way to manage allergies during pollen season.
