What is the specific effective medication for treating allergic rhinitis?

Currently, there are no specific drugs that can cure allergic rhinitis, but symptoms can be effectively controlled through standardized medication. Commonly used medications include mometasone furoate nasal spray, levocetirizine hydrochloride tablets, budesonide nasal spray, montelukast sodium chewable tablets, and azelastine hydrochloride nasal spray. If in doubt, it is recommended to consult a doctor in advance. Detailed explanations are as follows:

1. Mometasone Furoate Nasal Spray: A nasal corticosteroid that acts directly on inflamed areas in the nasal cavity, reducing mucosal edema and itching, and relieving symptoms such as nasal congestion and runny nose. It is administered once daily and is suitable for long-term maintenance therapy.

2. Levocetirizine Hydrochloride Tablets: An oral antihistamine that rapidly blocks histamine-mediated allergic reactions, alleviating symptoms like sneezing and nasal itching. It has a fast onset of action and relatively mild side effects, with once-daily dosing.

3. Budesonide Nasal Spray: Has potent anti-inflammatory effects, suppressing allergic inflammatory responses in the nasal mucosa and improving nasal airflow. It is suitable for moderate to severe allergic rhinitis and should be used regularly according to the recommended dosage.

4. Montelukast Sodium Chewable Tablets: A leukotriene receptor antagonist that reduces airway hyperresponsiveness. It is particularly suitable for patients with comorbid asthma or allergic conjunctivitis, helping to improve multiple allergic symptoms simultaneously. Taken once nightly.

5. Azelastine Hydrochloride Nasal Spray: A nasal antihistamine that acts locally in the nasal cavity, quickly relieving acute symptoms such as nasal itching and sneezing. It has a rapid onset and is used twice daily. Can be used short-term as needed.

Medication selection should be based on individual symptoms and conditions. Nasal preparations and oral medications may be combined to enhance efficacy. During treatment, exposure to allergens such as pollen and dust mites should be avoided, and indoor environments should remain clean and well-ventilated. If symptoms do not improve after taking medication, or if adverse effects such as nasal dryness or headache occur, medical attention should be sought promptly to adjust the treatment plan.
