Is 1 week of sulfamethoxazole-trimethoprim twice a day for pseudomonas aeruginosa a suitable treatment length?

The duration of therapy for this infection would generally be 14-21 days. Pseudomonas aeruginosa infections are becoming more difficult to treat due to increasing antibiotic resistance. In consideration of how serious a Pseudomonas aeruginosa infection can be & how difficult treatment can be I strongly encourage you to see an Infectious Disease specialist as soon as possible for further guidance.
