have the urine re-cultured after you are off the ampicillin. you may need to be examined to look for other possible causes to account for your continuing symptoms and definitely get examined if you are having any back (kidney area) pain.
i am taking ampicillin for a uti. i am worried it isn't treating it. how long should it take to feel no symptoms? . i was diagnosed with a uti. the doctor put me on cipro but due to previous issues with utis and kidney infections i asked them to culture my sample. a week later they called to tell me the bacteria in my urine was b streptococcus. i still had symptoms so they placed me on ampicillin which i have now been taking for 5 days. i still have symptoms and only 2 more days on the antibiotic. do i need to worry that it isn't being treated? should i call for a new antibiotic?
