Urinary tract infections can be treated with oral amoxicillin, but amoxicillin is not the best drug for treating urinary tract infections. Amoxicillin has the best bactericidal effect on Streptococcus haemolyticus, Streptococcus pneumoniae, Staphylococcus and other cocci, and also has a certain killing effect on Escherichia coli, Proteus mirabilis or Enterococcus faecalis. The vast majority of urinary tract infections may be infections such as E. coli, so taking amoxicillin for urinary tract infections is not the best choice. Quinolones and cephalosporins are the recommended antibiotics for urinary tract infections. For recurring urinary tract infections, it is necessary to pass a urine bacterial culture, and based on the results of the bacterial culture, choose the most sensitive antibiotic treatment to achieve the best results. Patients with urinary tract infections should drink more water and urinate more often during the treatment period to increase the physical flushing effect of urine on the urinary tract, which will help the treatment of urinary tract infections. Patients with urinary tract infections must use medication under the guidance of a doctor, and should not use medication on their own.
