2 days back i had some street food at night, 5 hrs later i got stomach ache and i had loose motion and then stomach ache receded Yesterday night i again got stomach ache and after sometime fever as well. Today morning i had mild fever, i took dolo tablet after lunch and fever has decreased now A doctor that i visited prescribed 3 kinds of tablets for stomach ache which are Taxim O 200 Bactrim ds Biotrim ds Since all 3 seem to be anti bacterial tablets (i happened to Google tablet names), is it safe to take all 3 together and is it required that i take all 3?
