Dear doctor,For four days, I have very watery diarrhea, cramps, and nausea. Vomiting only twice. Yesterday, I was prescribed Levofloxacin 500 mg for four days. Now, after 24 hours of taking the first pill, there is no improvement. Diarrhea is 20 times a day very watery. I take electrolytes and lots of liquids. The blood test showed a bacterial infection. Stool test was normal. So my questions are: When usually antibiotics start working? Is Levofloxacin a good medicine for this kind of diarrhea?
Hello, Welcome to Chat Doctor forum. From what you mentioned, most likely you have acute gastroenteritis. Ciprofloxacin is a very good antibiotic for gastroenteritis. You have to complete a four-day course at least. It may take few days before you see a good result. I suggest: Consult your specialist doctor, discuss with him or her and start taking the medicines with their consent. I hope I answered all your questions.
