For patients with mild intermittent attacks, we recommend oral loratadine or cetirizine as the first antihistamines, because it is very convenient, fast-acting (30 minutes), accurate and inexpensive, and nasal spray antihistamines (azelastine, levocabastine) or nasal spray hormones (budesonide, furosemide, fluticasone propionate) are used if you do not want to take them orally. Hormones (budesonide, mometasone furoate, fluticasone propionate) are generally effective, with the fastest onset of action (15 minutes) for patients who are not regularly randomized and for emergency patients. For patients with more severe persistent attacks we recommend a combination of medication, i.e. nasal spray plus oral medication. In addition, patients with severe nasal congestion can increase the use of decongestants (hydroxymetazoline hydrochloride, etc.) but it should be remembered that these drugs cannot be applied continuously for a long time and need to be used intermittently, otherwise they may easily lead to drug rhinitis. Finally, appropriate nasal saline rinse or spray treatment is also a good way to relieve symptoms.
