1.1 Current evidence on the efficacy and safety of intranasal phototherapy for allergic rhinitis is limited in quantity and quality. Therefore, this procedure should only be used in the context of research. Find out what only in research means on the NICE interventional procedures guidance page.

1.2 Further research should include: details of patient selection including medication use; underlying medical conditions; the intensity, duration and wavelength of light used; patient-reported outcomes; comparison with existing treatments; and the effects of repeated long-term use. NICE may update the guidance if further evidence is published.
