What should you know about pressure ulcer antibiotics?

A pressure ulcer is a wound caused by prolonged pressure, friction, or shear, often over a bony area. Not every ulcer needs an antibiotic. Clinicians look for increasing redness or warmth around the wound, swelling, worsening pain, pus, an unpleasant smell with other infection signs, fever, or feeling unwell. Antibiotics do not replace pressure relief, cleansing, dressings, nutrition support, or treatment of conditions that slow healing. The medicine and route depend on the infection, allergies, other medicines, kidney function, and the wound assessment.

Keep the dressing and surrounding skin as instructed, avoid rubbing or picking the wound, and change position regularly using an appropriate support surface. Do not apply leftover antibiotics, antiseptics, or home remedies unless a clinician recommends them. If prescribed an antibiotic, take it exactly as directed and report a rash, breathing difficulty, severe diarrhoea, or other unexpected reaction. A clinician may need to clean dead tissue, take a sample, or arrange wound-care follow-up. Cellulitis is one condition that can involve spreading skin infection and requires clinical assessment.

Seek urgent help for fever, confusion, faintness, rapidly spreading redness, severe or rapidly increasing pain, red streaks, black or grey tissue, or a sudden decline in general health. Arrange prompt wound assessment if the ulcer is enlarging, has new drainage or odour, exposes deeper tissue, or is not improving. People with diabetes, poor circulation, reduced sensation, or a weakened immune system should seek advice early because infection may progress without dramatic skin changes.

Ask whether the ulcer is infected, what wound-care plan supports healing, how pressure should be reduced, and how soon it should be reviewed. Mention allergies, recent antibiotics, diabetes, circulation problems, and any change in pain or discharge.
