There is no course of antibiotic treatment, mainly based on the patient’s condition recovery to determine whether to stop the drug, because antibiotics have an anti-infective effect, so often given to the patient may cause intestinal flora imbalance. For most common infections, antibiotics are given for about 3-5 days and the condition is well relieved, at which point the medication can be stopped. There are very many types of antibiotics, the more common ones being penicillins, cephalosporins, aminoglycosides, tetracyclines and so on. It should be noted that the use and discontinuation of antibiotics have strict standards, the patient needs to follow the doctor’s instructions, can not be taken privately, and can not be stopped without authorization, so as not to cause adverse effects on health.
