The most common bacteria causing acute cystitis is Escherichia coli. Oral treatment with quinolone drugs, such as levofloxacin and ciprofloxacin, can be used.
However, with the current overuse of antibiotics, the phenomenon of acute cystitis patients developing resistance to quinolone drugs is gradually increasing.

Therefore, based on current experience, it is recommended to take semi - synthetic penicillins, such as amoxicillin clavulanate potassium or clarithromycin, for treatment.
