Doxycycline Coverage of Pseudomonas aeruginosa
Doxycycline is not reliable therapy for infections caused by Pseudomonas aeruginosa. [1]
Spectrum and FDA-Listed Indications
Doxycycline is indicated for specific gram-negative organisms, but Pseudomonas aeruginosa is not listed among them. [1]
Clinical Implication
Doxycycline should not be selected as targeted therapy for suspected or confirmed P. aeruginosa infection without microbiologic susceptibility results. [1]
When Doxycycline Might Still Appear in Practice
Doxycycline may be used when other pathogens covered by doxycycline are identified or strongly suspected, but it should not substitute for antipseudomonal agents when P. aeruginosa coverage is required. [1]
Recommended Next Step
Antimicrobial selection should be guided by culture results and susceptibility testing for the P. aeruginosa isolate. [1]
