Is nasal steroid spray bottle contamination a potential issue in chronic rhinosinusitis? The Journal of Laryngology & Otology, 12/24/2013 Clinical Article Tana NCW, et al. –
Intranasal steroids are the first line of treatment for chronic rhinosinusitis. Although contamination of adjunctive devices (e.g. irrigation bottles) has been much investigated, little is known about nasal contamination of the metered–dose spray bottles used to deliver intranasal steroids, and the potential influence on disease chronicity. Nasal steroid spray bottle tips can become contaminated with sinonasal cavity bacteria. Simple sterilisation methods can eliminate this contamination. Patient education on this matter should be emphasised.
