This is the antibiotics that I was on

cephALEXin 500 mg capsule for 7 days. I stopped taking them the day before yesterday. I experienced no side effects when on the antibiotics. The antibiotics were started before the culture came back.

Brief Answer:
Antibiotic side effects

Detailed Answer:
Hi
I have reviewed the report sent by you
It mentions that you grew E Coli
And the antibiotic was not changed because as per the report, the bacteria was sensitive to the antibiotic
in other words, you would have felt better with same antobotics.

What you have now developed are the side effects of the antibiotic that you have been on. Loosemotions, fever with chill etc are all part of the side effects of the antibiotic you have been on.

You will need a change of antibiotics. Usually the culture gives a list of antibiotics that we can use. However your report does not do so. Therefore I am unable to make a suitable suggestion.

You will need to meet the treating doctor for a change in the antibiotic in view of the side effects

Thanks
Best of luck
