The treatment of UTI in women does not always require injections or fluids, and oral medication is an option. If you want the effect to work faster, or consider the pathogen of urethritis is more complex, is a complex urinary tract infection, you can first 3-5 days of infusion or injection anti-infection treatment, and then you can change these drugs to oral, and then continue to use the drug for 7-10 days. It is important to note that in the treatment of female UTIs, the medication cannot be stopped immediately after the symptoms have improved. After the symptoms have improved and the urine routine has turned negative, the medication must be continued for more than 1 week so as to better eradicate the infection, and also to prevent the emergence of bacterial resistance, so as to avoid recurrence of the infection and chronicity of the infection. Therefore, if a woman has a UTI that requires fluids or injections for anti-infection treatment, she may need to use the medication for 3-5 days before switching to oral medication to continue treatment.
