It is true that allergic rhinitis cannot be cured clinically, because its onset is mainly due to the poor resistance of the patient, who may live or work in an environment where they are often exposed to allergens, which can lead to the recurring onset of allergic rhinitis symptoms in patients, and sometimes there is also a relationship with genetic factors. It is recommended that patients actively control the disease when it occurs, and when it does not occur, they need to exercise more to improve their resistance. Commonly used clinical anti-allergy drugs include cetirizine hydrochloride capsules and montelukast sodium tablets, etc. Patients are advised to apply them selectively. Immune desensitization therapy can also be considered, but it does not guarantee complete eradication. It is recommended to take oral vitamin C tablets to improve immunity.
