There is no course of antibiotic treatment, and the need to stop is determined mainly by the patient’s recovery. Because antibiotics have an anti-infective effect, frequent administration may cause dysbiosis of the intestinal flora. The vast majority of common infections can be discontinued after about 3-5 days of antibiotics, when the condition is well relieved. There are very many types of antibiotics, the more common ones are penicillins, cephalosporins, aminoglycosides, tetracyclines, etc. It should be noted that there are strict standards for the use and discontinuation of antibiotics, and patients need to follow the doctor’s instructions and not take them privately or stop them without permission to avoid adverse health effects.
