what is the best antibiotic for gastroenteritis? - #16422

Sara

I am really worried about my son who just came down with gastroenteritis. It started a few days ago with nausea and then he ended up having a bunch of bouts of vomiting, and now he's got diarrhea too. He’s really feeling weak, and I'm just praying he doesn’t get dehydrated. The doctor said if it doesn’t clear up soon, they might wanna do some tests, but I'm freaking out wondering what to do in the meantime. Can anyone tell me what is the best antibiotic for gastroenteritis, if any? The doc didn't prescribe any antibiotics yet and just suggested keeping him hydrated with electrolyte drinks, but I keep seeing things online about different types of antibiotics that can help. I don't know if we should be waiting or if we should be pushing for something like that, ya know? I just wanna make sure he’s getting the right treatment. Like, is it common to use antibiotics for gastroenteritis at all? I read something about viral vs bacterial, but figuring all this out is kinda stressful. What is the best antibiotic for gastroenteritis if it is bacterial? Would I need to go back to the doctor for this stuff? Any advice would be super helpful!

The best approach to treating gastroenteritis really depends on whether it’s viral or bacterial. Most cases of gastroenteritis, especially in children, are viral, and antibiotics are not effective in these situations. For viral gastroenteritis, supportive care like ensuring proper hydration is crucial. This includes giving your son oral rehydration solutions or electrolyte drinks, as your doctor suggested. If the cause is bacterial, then antibiotics might be necessary, but only after a proper diagnosis by a healthcare professional. Common bacterial causes include infections like Campylobacter, Salmonella, Shigella, or certain types of E. coli. Each of these might require a specific antibiotic, so there isn’t a one-size-fits-all. For instance, in cases caused by Campylobacter, azithromycin is sometimes used. If it’s a case of Shigella, then a different antibiotic might be more appropriate. Also, antibiotics aren’t typically given for E. coli infections because they can increase complications in certain strains like E. coli O157:H7. Symptomatically, if signs of severe dehydration appear—like decreased urination, dry mouth, lethargy, or if he becomes unable to keep any fluids down—it’s important consult your doctor immediately or go to a healthcare facility. At this point, seeking medical advice again is wise, as they could recommend further tests or interventions if your son isn’t improving. It’s understandable to be concerned, but it’s often a matter of letting the illness run its course if it’s viral, focusing on hydration, and watching for red flags. Keep in touch with your healthcare provider to determine the best course of action.
