Hello! Thanks for putting your query in HCM. I am a Gastroenterologist (DM).
I think you are suffering fro acute infectious enteritis
for which you simply require a course of antibiotics like ofloxacin
is due to pepto bismo
which you have taken as it is its common side effect. So nothing to worry about that.
I hope I have answered your query and this will help you. Remain in touch and get-well soon.
