Pseudomonas aeruginosa lung infections generally take about 2 weeks to treat, and may take about 2 to 4 weeks if resistance develops.
Treatment of Pseudomonas aeruginosa lung infections generally takes about 2 weeks, which is longer than the usual treatment of pneumonia, which takes 2 weeks in the usual course of treatment. The infection is usually controlled during this treatment period and the patient can be discharged from the hospital when the indications for discharge are met.
However, because Pseudomonas aeruginosa lung infections are usually nosocomial, the potential for drug resistance is high. In case of drug resistance, drug sensitivity test, sputum culture and other tests are needed to identify the sensitive antibiotics for treatment, which may take about 2~4 weeks. The details need to be determined after consulting one’s attending physician.
