The best treatment for rhinitis in children is to avoid repeated cold and flu stimulation that can lead to recurrence as well as aggravation of rhinitis. If its conservative treatment does not work well, you can consider oral medications such as Cangzhi Rhinitis Drops or Nasal Yuanshu Oral Liquid, and you can use the nasal spray medication Cochlearia or Endosolina. If the symptoms of sinusitis are severe, the antibiotic amoxicillin capsules or cefradine capsules can be applied at the same time. If the effect is not particularly good, alternate treatment can be applied. If the inflammation is limited to maxillary sinusitis, consider maxillary sinus puncture treatment at this time.
