Antibiotics for a Pseudomonas Skin Infection

Pseudomonas can resist antibiotics that treat more routine skin infections. A clinician may collect fluid or a swab for laboratory testing, especially when infection is extensive, recurrent, or not improving.

Pseudomonas is a type of bacterium that can infect damaged or persistently wet skin. Possible features include painful redness, warmth, swelling, drainage, an unpleasant smell, or inflamed bumps after exposure to contaminated water. Appearance alone cannot reliably identify the organism.

Treatment differs from care for boils, cellulitis, and folliculitis caused by other bacteria. The clinician considers the body area involved, whether there is an abscess or wound, immune health, recent antibiotic use, and culture findings before choosing a medicine.

Keep the area clean and gently dry, cover draining skin with a clean dressing, and avoid swimming or sharing towels. Do not squeeze lesions or use leftover antibiotics. The wrong drug can delay effective care and cause side effects.

If an antibiotic is prescribed, take it exactly as directed and tell the prescriber about allergies, pregnancy, kidney problems, other medicines, and previous resistant infections. Some collections of pus also need drainage; tablets alone may not solve that problem.

Seek prompt medical care for rapidly spreading redness, worsening pain, fever, chills, red streaks, significant swelling, confusion, or skin turning dusky or black. Infection near the eye, a deep wound, or infection in someone with diabetes, poor circulation, or reduced immunity also warrants early assessment.

Contact the prescriber if symptoms worsen after treatment starts, new drainage appears, or medicine causes facial swelling, breathing difficulty, a widespread blistering rash, persistent vomiting, or severe diarrhoea. Breathing difficulty or facial swelling requires emergency help.

Ask whether a culture is needed, whether there is fluid that should be drained, how the dressing should be changed, and what specific change would mean the treatment is not working. Confirm when results will be reviewed and whether the antibiotic may need adjustment.
