How effective are antibiotics for cellulitis?

Cellulitis affects deeper skin and nearby soft tissue, so redness, warmth, swelling, and tenderness can expand beyond a small visible spot. Antibiotics target the bacteria responsible; a clinician chooses an oral or intravenous option according to symptoms, examination, ability to take medicine, and overall health. The skin can look inflamed for a while even after bacteria are being controlled, so progress is judged by the direction of symptoms and your general condition.

Have suspected cellulitis assessed promptly and follow the prescribed schedule closely. Keep the affected area clean, elevate an arm or leg when practical to limit swelling, and mark the edge of redness only if a clinician recommends it. Do not massage the area, apply irritating products, or stop treatment early because it looks better. A clinician may also look for an entry point such as a cut, blister, ulcer, or fungal infection between the toes.

Get urgent help if redness is spreading quickly, pain is severe, fever or chills develop, you feel faint or confused, or the affected area is near the eye. Emergency assessment is needed for breathing difficulty, collapse, or rapidly worsening illness. Contact the treating clinician if symptoms are not beginning to settle, return after improving, or you develop a troublesome reaction such as facial swelling or widespread rash.

Ask which features suggest cellulitis rather than an abscess, how improvement will be checked, and whether a wound or skin condition could have allowed bacteria in. Clarify when to return, how to manage swelling, and which medication effects need immediate advice.
