Loratadine is mainly used for the treatment of allergic rhinitis. If the patient’s symptoms are severe, consider taking oral loratadine dispersible tablets or loratadine capsules and observe the patient’s clinical performance for about one week of application. If the patient’s symptoms improve significantly after medication, it is recommended to consolidate the oral medication for another three days. If the patient’s symptoms persist, consider continuing the medication for another week or so to observe the patient’s condition. Loratadine is an anti-allergy drug and patients may become sleepy after application, so it is recommended to take it before bedtime to avoid affecting normal work and life. For patients with allergic rhinitis, you can consider spraying endosulfan or ryanodine inside the nose. After active symptomatic treatment, the patient’s symptoms of allergic rhinitis will definitely improve.
