Nesuna nasal spray (mometasone furoate nasal spray) is a kind of nasal glucocorticoid, which is the first-line drug for the treatment of allergic rhinitis, i.e., the preferred drug. nesuna nasal spray can be used for children over 2 years old with a clear diagnosis of allergic rhinitis. Parents are afraid when they hear the word hormone, and often doctors prescribe the drug without using it, causing the symptoms of rhinitis to continue to be bad, affecting the child’s mental state, academic performance, and in some cases, inducing asthma. The nasal spray is a topical glucocorticoid that does not cause systemic effects at the dose of local anti-inflammatory effects, usually one spray per nostril, in the morning or at bedtime. Always do a nasal rinse with sea salt water before nasal spraying of endosuction for better results. We have found that some children have side effects of nasal bleeding during the course of the medication. At this time, it is necessary to stop using Endosolana for a few days and stick to the nasal rinse with sea salt water and other oral medications for allergic rhinitis.
