Inflammation of the urethra can be treated with oral ciprofloxacin tablets, 1 tablet, 3 times daily, or oral levofloxacin capsules, 1 capsule, 3 times daily. If the patient is resistant or allergic to quinolones, i.e. ciprofloxacin and levofloxacin, they can switch to cephalosporin antibiotics. Commonly used cephalosporin antibiotics are cefixime capsules, 1 capsule, 2-3 times daily, or cefprozil tablets, 1 tablet, 3 times daily, with a usual treatment cycle of 1 week. If the symptoms do not improve after 3 days of oral medication, routine urine tests and ultrasound examination of the urinary tract should be performed at the hospital to rule out infection caused by other factors such as stones or tumors. If necessary, medication should be adjusted according to the test results, or surgery or special invasive tests should be performed. You need to keep a certain amount of water during oral medication, and if the urine is more frequent, you can add one tablet of sodium bicarbonate three times a day.
