Combined use of antibiotics

The purpose of combined drug use is to improve disease treatment effect, reduce bacterial resistance, reduce adverse reactions, and expand the scope of antibacterial. However, the indications of combined use of antibiotics should be strictly mastered, such as mixed infection that cannot be controlled by a single antibiotic, such as peritonitis caused by abdominal organ damage; Serious infections that cannot be controlled by a single antibiotic, such as sepsis, sepsis and other serious infections; Infection sites that are not easily penetrated by single antibiotic, such as tuberculosis infection; Severe infection of which the pathogen has not been determined. If the pathogen is treated for a long time, it may lead to drug resistance, so it should be combined with drugs. Please refer to relevant books or literatures for specific principles of combination, or follow the doctor's advice
