After a urinary tract infection in women, it is recommended to perform a urine culture and select the most sensitive antibiotic that works fastest based on the results of the bacteria cultured. Commonly used drugs: First, antibiotics of quinolones. They have a relatively high concentration in the urine, a relatively strong bactericidal ability, and no significant drug resistance for the vast majority of bacteria in urinary tract infections. For example, levofloxacin hydrochloride capsules, ciprofloxacin tablets, or moxifloxacin tablets are more effective. Moxifloxacin has the best effect, but it is also more expensive. Secondly, cephalosporin is an antimicrobial agent with relatively small side effects in the digestive tract after oral administration and quick onset of action, but some patients may have allergies to cephalosporins. Commonly used drugs include cefixime capsules, cefuroxime tablets, etc. Third, drugs to reduce the symptoms of urinary tract irritation, such as drugs to alkalize the urine, sodium bicarbonate tablets. Or drugs to improve bladder spasm, such as flavone permethrin hydrochloride tablets, etc. They need to be treated together with antibacterial agents after oral administration.
