Mometasone Furoate Nasal Spray is a nasal spray that treats allergic rhinitis and costs about$60-70. Mometasone Furoate Nasal Spray is a glucocorticoid, which is relatively fused to the human body, and has a better safety profile.It can be used by children over the age of 3 years old, and children between the ages of 3-11 years old are usually sprayed once in each nasal cavity, once a day. Adults are sprayed twice per nasal cavity, once a day. When spraying the nose, the left nasal cavity should be sprayed with the right hand, and the right nasal cavity should be sprayed with the left hand, so that the medicine can be sprayed to the nasal mucosa in the deep part of the nasal cavity and will not be sprayed to the nasal septum. If sprayed on the nasal septum will cause irritation to the septum, the effect of the drug will be poorer. In addition to spraying the nose, allergic rhinitis patients can also eat montelukast sodium tablets or montelukast sodium chewable tablets and other anti-allergy drugs are also more effective.
