If a patient with allergic rhinitis has a stuffy nose, runny nose and sneezing, consider applying montelukast sodium tablets as an anti-allergy. Patients are generally advised to observe changes in their condition for about five days after application, and if the symptoms improve significantly, they are advised to discontinue the use of montelukast sodium tablets and apply nasal spray alone to consolidate the treatment. The commonly used nasal sprays are budesonide nasal spray, or tretinoin nasal spray. If the patient’s symptoms of allergic rhinitis do not improve significantly, it is recommended that the patient actively consolidate treatment for another week. It is important to drink more water after medication to promote the absorption and metabolism of the drug. Montelukast Sodium Tablets are anti-allergy drugs, so patients may be sleepy after taking them, so it is best to take them before bedtime. The diet must be light, avoiding spicy and stimulating foods, as well as reasonable rest and relaxation.
