Those medications for allergic rhinitis medication is the main treatment for allergic rhinitis, commonly used drugs include: antihistamines such as loratadine and cetirizine, which are effective in treating nasal itching, sneezing and increased nasal discharge; nasal glucocorticoids such as Berkner, Renolcort, and Cochlear, which have strong local effects on the nasal mucosa without systemic side effects. Mast cell stabilizers such as sodium cromoglycate can relieve nasal symptoms; nasal decongestants such as ephedrine can quickly reduce nasal congestion. 3. Can allergic rhinitis be treated surgically? Surgery itself cannot treat allergies and is only applicable to patients with allergic rhinitis who also have enlarged turbinates and deviated nasal septum causing nasal congestion. Surgery is only considered in the following cases: enlarged inferior turbinates, for which medication is ineffective; with structural abnormalities such as deviated nasal septum that affect nasal function; with other diseases suitable for surgical treatment, such as secondary sinusitis, nasal polyps, etc.
