Fluticasone can be especially helpful for people with allergies and/or OSA. "Intranasal fluticasone treatment may be useful for patients with nasal obstruction-related obstructive sleep apnea to improve sleep quality and limit daytime dysfunction." https://pubmed.ncbi.nlm.nih.gov/31521518/ https://pubmed.ncbi.nlm.nih.gov/31521518/ "Intranasal steroids and montelukast did not decrease AHI; however, total sleep time and percent of stage R sleep significantly increased. Self-reported improvement could be explained by observed changes in sleep parameters. Larger prospective studies could help elucidate the effects of medical therapy on adult patients with OSA." https://pubmed.ncbi.nlm.nih.gov/31383235/ https://pubmed.ncbi.nlm.nih.gov/31383235/
