Roxithromycin is a macrolide antibiotic, which is effective for rhinitis treatment, especially for allergic rhinitis. Other normal simple rhinitis and chronic rhinitis, the effect of taking rosithromycin alone for rhinitis is not reliable. The purpose of taking roxithromycin is because there are anaerobic bacteria in the nasal cavity or sinuses, and roxithromycin has an effect on anaerobic bacteria, which will give better results. As opposed to taking cephalosporin antibiotics, when treating rhinitis you cannot simply take a separate drug, you will usually do rinses, sprays or auxiliary herbs, and also do the corresponding massage, hot steam inhalation, etc. Taking rosmarinic acid alone for rhinitis is not the best choice.
