Antibiotics for skin inflammation

Redness, warmth, swelling and soreness can occur with infection, but also with eczema, allergy, irritation, bites or other inflammatory problems. A clinician may need to inspect the skin before deciding whether an antibiotic is appropriate.

Bacterial skin infection may develop when germs enter through a cut, crack, ulcer or scratched area. Cellulitis can present with an expanding patch of painful, hot, swollen skin, sometimes alongside fever or feeling unwell.

Antibiotics do not treat inflammation caused by viruses, fungi, allergy or non-infectious skin conditions. Using them unnecessarily can cause side effects and makes future bacterial infections harder to treat. The location, speed of spread, discharge and any break in the skin help guide the assessment.

Arrange a medical assessment if redness is spreading, the area is increasingly painful or warm, pus is present, or symptoms are worsening. Keep the area clean, avoid squeezing or scratching it, and cover broken skin with a clean dressing.

If an antibiotic is prescribed, take it exactly as directed and complete the prescribed course unless the prescriber tells you to stop. Mention medicine allergies, pregnancy, kidney or liver problems, and other medicines. Seek advice if symptoms worsen despite treatment or troublesome diarrhoea, vomiting or a new rash develops.

Get urgent medical help for rapidly spreading redness, severe or escalating pain, fever with marked weakness, confusion, blistering, darkened skin, or swelling around the eye. Breathing difficulty, facial or throat swelling, or faintness after an antibiotic may signal a serious allergic reaction and needs emergency care.

Earlier assessment is also sensible when inflammation affects a surgical wound, when an immune condition or medicine weakens infection defences, or when diabetes or poor circulation may delay healing.

Ask what features suggest infection, whether a swab or other test is needed, how soon improvement should become noticeable, and what change should prompt reassessment. Confirm how to take the medicine and what to do after a missed dose.
