The drug commonly used for injections for patients with allergic rhinitis is compound betamethasone injection. Patients with allergic rhinitis who are allergic to pollen and experience symptoms such as profuse clear watery nasal discharge, sneezing, nasal itching and nasal congestion in spring or autumn can use compound betamethasone injection for intramuscular injection. In addition, patients with allergic rhinitis can also get anti-inflammatory and anti-swelling injections of tretinoin acetate to delay the allergic reaction, reduce the expansion of the primary immune response, and relieve the symptoms of rhinitis. However, compound betamethasone injection and tretinoin acetate injection are hormonal drugs and are not recommended for long-term use by patients. After long-term use, patients may develop medically induced Cushing’s syndrome, i.e. cortisolism, with manifestations such as weight gain, purple lines and swelling of lower limbs, and patients may also develop psychiatric symptoms, such as agitation and delirium. In addition, patients with hormone contraindications, such as diabetes, hypertension, ulcer disease, and other hormone contraindications are contraindicated. Patients with allergic rhinitis are recommended to be treated with oral medications, such as anti-allergy drugs, antihistamines, loratadine tablets or cetirizine hydrochloride, and also with hormonal nasal sprays, such as mometasone furoate or budesonide nasal spray for topical treatment, which are more effective. In addition, patients can also use nasal saline and seawater for nasal irrigation to remove allergens and nasal secretions from the nasal cavity. If patients have significant nasal congestion, they can use nasal decongestants, such as hydroxymetazoline hydrochloride spray for nasal spray, to relieve the symptoms of rhinitis.
