Objective:
To evaluate and determine the prevalence of ingredients in over-the-counter (OTC) nasal sprays.
Study Design:
Cross-sectional.
Setting:
Retail pharmacies.
Methods:
An inventory of brand-name and generic OTC nasal sprays was recorded at five national pharmacy outlets in August 2023. Data regarding the active ingredients were collected on commercial websites, MedlinePlus and drugs.com, and frequency statistics were calculated.
Results:
Five pharmacies were visited, at which 12 different brand names of nasal sprays were identified at multiple pharmacies. Nine brand names were associated with multiple formulations, accounting for 49 different products. The active ingredients included in our analysis were oxymetazoline, phenylephrine, fluticasone, triamcinolone, budesonide, azelastine, cromolyn sodium, and mometasone. Nasal decongestants had the greatest number of brand name formulations compared to intranasal steroids and antihistamine sprays which had limited choices. Products that included oxymetazoline were the most widely marketed drug (51 unique products) followed sodium chloride (40 unique products).
Conclusion:
These findings suggest that there are widespread redundancies in the OTC nasal spray market. Clinician should be aware of the redundancy in OTC formulations and encourage patients to read the labels in order to make informed decisions regarding their use of OTC medications.
