Antibiotic treatment for MRSA cellulitis

MRSA resists several commonly used antibiotics, so treatment should be selected by a clinician rather than borrowed or chosen from leftovers. Oral medicine may suit some stable infections, while severe illness can require hospital care and antibiotic treatment through a vein.

Cellulitis affects deeper layers of skin and commonly presents with expanding redness, warmth, swelling and tenderness. MRSA is a type of Staphylococcus aureus with resistance to certain medicines; the label does not indicate how severe an individual infection is.

A pus-filled collection suggests an abscess as well as surrounding inflammation. Drainage can be central to controlling a collection because antibiotics may not penetrate a closed pocket adequately. A sample of pus may help refine treatment when the response is poor or resistance is a concern.

Take the prescribed medicine at the scheduled times and follow the stated course. Keep any wound clean and covered, wash hands after touching dressings, and avoid sharing towels or razors. Rest and elevate an affected arm or leg when comfortable to help swelling.

Monitor whether the painful area is enlarging and note new fever, drainage or blistering. Contact the treating service if doses are missed, vomiting prevents medicine staying down, side effects occur, or the skin continues to worsen despite treatment.

Arrange same-day assessment for quickly spreading redness, increasing swelling or pain, fever, pus, red streaking, or infection near an eye, hand or joint. Reduced immunity, poor circulation and diabetes also lower the threshold for prompt review.

Seek emergency help for confusion, faintness, breathing difficulty, cold or mottled skin, severe weakness, or rapidly progressing skin changes. These signs can accompany a serious body-wide response to infection.

Ask which changes would show that treatment is working, whether a collection needs drainage, how culture results could alter the antibiotic, and what to do if a dose is missed or a rash develops.
