To treat a UTI effectively, targeted antibiotics are necessary. Your current medications are highly appropriate: cefixime is an antibiotic that treats the underlying bacterial infection, while flavoxate is a urinary antispasmodic that relieves bladder spasms and painful urination. Please complete the full antibiotic course as prescribed by your doctor. For home care, drink plenty of water to flush out bacteria and avoid bladder irritants like caffeine and alcohol. Cranberry supplements may also help. Rest assured, UTIs are very common and highly treatable. If symptoms persist after a few days, consult your doctor for a urine culture to ensure the bacteria is fully targeted.
