Antibiotics for Pseudomonas aeruginosa

Because this bacterium can resist multiple medicines, treatment should be prescribed for the individual infection rather than copied from someone else or from a previous episode. A result from a non-sterile site can indicate carriage, so the clinical picture determines whether it represents disease.

Pseudomonas aeruginosa may infect the lungs, urinary tract, wounds, burns, outer ear, bloodstream, or medical devices. Antibiotic penetration differs across these sites. The care team also weighs organ function, allergy history, recent antibiotic exposure, immune status, and whether bacteria have entered the blood.

For a serious illness, clinicians may start broad antipseudomonal coverage before the laboratory report returns. They can then narrow therapy to an active drug. This approach reduces unnecessary exposure while ensuring that the medicine reaches the infected tissue at an appropriate dose.

Use every dose as directed and check before taking antacids, supplements, or new medicines because some combinations affect absorption or side effects. If a dose is missed or vomiting occurs, follow the product instructions or contact the pharmacy rather than doubling the next dose.

Complete requested blood tests and clinical reviews. Depending on the medicine, clinicians may monitor kidney function, liver function, blood counts, hearing, or heart rhythm. Wound cleaning, abscess drainage, removal of an infected line, or relief of a urinary blockage may be as important as the antimicrobial itself.

Call emergency services for difficulty breathing, bluish or grey skin, collapse, severe confusion, inability to wake normally, or a rapid overall decline. Urgent assessment is also needed for intense pain with quickly advancing swelling or skin colour change.

Seek same-day advice when symptoms progress after treatment begins, fever returns, a wound spreads beyond its marked edge, fluids or doses cannot be retained, or urine becomes very limited. Stop and obtain emergency help for throat tightness, facial swelling, wheezing, or widespread blistering after an antibiotic.

Ask where the infection is located, what the susceptibility report shows, how long the planned course is, and which monitoring tests are required. Confirm whether a device or collection of pus needs treatment and how the team will judge that the infection is responding.
