Introduction
普通轻症感染如急性支气管炎、单纯尿路感染等，病情较轻且无并发症，抗菌Medicine使用时间多为3-7天。Symptoms缓解后再巩固1-2天即可停药，避免过量使用导致耐药性或肠道菌群失调，这类情况无需长期用药就能达到TreatmentEffect。
Generally, the duration of antimicrobial use depends on the type of infection, severity of illness, and treatment response, typically ranging from 3 to 14 days. Mild infections usually require shorter treatment courses, while severe or special infections may need prolonged therapy. If in doubt, it is recommended to consult a healthcare provider early. Detailed analysis is as follows:
For common mild infections such as acute bronchitis or uncomplicated urinary tract infections, where the condition is mild and without complications, antimicrobial treatment usually lasts 3–7 days. Medication can be discontinued 1–2 days after symptom relief to consolidate the effect, avoiding excessive use that could lead to antibiotic resistance or gut microbiota imbalance. In these cases, long-term medication is unnecessary to achieve therapeutic success.
For severe infections such as pneumonia, sepsis, or osteomyelitis, or infections caused by drug-resistant bacteria or specific pathogens, treatment duration should be extended to 7–14 days or even longer in some cases. Discontinuation of medication should only occur after complete resolution of symptoms and normalization of laboratory indicators, ensuring thorough elimination of the pathogen and preventing recurrence or chronic transformation. Strict adherence to the prescribed course is essential in such situations.
Antimicrobial agents must be used strictly as directed by a physician; patients should not shorten or extend the treatment course on their own. Monitor symptom changes during treatment and promptly report any abnormalities to the doctor.
