Children who have rhinitis can apply Montelukast Sodium Tablets for about a week. But after using the medicine, you must drink more water to promote the absorption and metabolism of the drug. Montelukast Sodium can effectively reduce the degree of sensitivity of the nasal mucosa of the patient and alleviate the symptoms of runny nose and sneezing. Because children may become sleepy after applying Montelukast Sodium, it is best to take it before bedtime to avoid affecting normal life and study. In addition to the application of montelukast sodium, physiological sea saline or mometasone furoate nasal spray can also be sprayed inside the nose to alleviate the symptoms of nasal congestion. If the child’s symptoms do not improve after active symptomatic treatment, you can consider going to the hospital for further consultation to avoid delaying the child’s condition. The child should be allowed to exercise more, to improve their own immune system.
