It is useful to take amoxicillin for enteritis, but amoxicillin is not the preferred medication. The preferred medication is probiotics, such as Clostridium typhimurium live tablets or Bacillus subtilis live capsules, because probiotics can play a role in regulating intestinal flora disorders, so it can be used to treat diarrhea, constipation, abdominal discomfort and other symptoms that occur in enteritis patients. Amoxicillin is a broad-spectrum antibiotic, although it has a strong killing effect on both gram-negative and gram-positive bacteria, but it is mainly suitable for respiratory tract, urinary tract, and also biliary tract infections as well as typhoid. If you need to use antibiotics to treat intestinal infections, the preferred antibiotics are quinolones, such as norfloxacin, which is more commonly used in clinical practice, but before using antibiotics, patients need to cooperate with doctors to improve the relevant examination, only if there is a clear presence of bacterial infection and is a serious infection, you can use antibiotics to avoid the emergence of bacterial drug resistance.
