A cough that gets worse after taking medication for laryngitis may be secondary to complications such as bronchitis and pneumonia, which can be treated with sensitive antibiotics, as well as symptomatic treatment. It is also possible that the medication is not the right one. Laryngitis can be caused by infection, gastroesophageal reflux, or stimulated by adverse factors, and the symptoms can persist if the medication is not the right one. 1. Sensitive antibiotics: If it is a bacterial infection, you can use penicillin, cephalosporin, levofloxacin hydrochloride and other antibiotics to treat the infection; if it is a mycoplasma infection, you can use azithromycin, erythromycin and other antibiotics for anti-infective treatment; Influenza viral infection can be selected from oseltamivir and other drugs. 2. Symptomatic treatment: for patients with a lot of sputum, you can take bromoacetin hydrochloride tablets, ambroxol and other sputum diluting drugs; if accompanied by wheezing dyspnea, you can take salbutamol, aminophylline and other drugs. 3. The use of medication is not appropriate: laryngitis patients should first go to the hospital to find out the cause of laryngitis, follow the doctor’s instructions for medication, to avoid self-medication, delayed diagnosis and treatment. It is recommended to go to the hospital for examination first, after a clear diagnosis, follow the doctor’s prescription medication.
