This is Dr. David
the best way to pick the proper antibiotic is to use a urinalysis and urine culture and sensitity panel to tell what antibioitc the infection is sensitive to
kidney infections will shed bacteria into the urine
you need a proper urinalysis and urine culture and a sensitivity and resistance panel to be performed on your urine
this will tell if your bacterial infection is sensitive to PROMOX which is amoxicillin or if you need other antibiotics to treat an infection.
some infections require IV antibiotics for treatment.
I'm surprised your doctors have not performed this simple urine culture test
I suspect they may have this information in the lab and you need to contact your doctors to see if your antibiotic is still the right one to be taking.
let me know if you have other questions.
