How effective is antibiotic treatment for cellulitis?

Cellulitis is a deeper bacterial skin infection that can cause spreading redness, warmth, swelling and tenderness. A clinician may prescribe tablets for a suitable mild case, while more serious infection may need treatment in a healthcare setting. The skin can remain red or sore for a while even after the bacteria are being controlled, so the overall direction of symptoms matters more than one isolated change.

Take each dose exactly as prescribed and do not stop early because the skin looks better. Rest the affected limb and raise it when practical to help with swelling. Marking the edge of redness can help you notice whether it is extending, but do not delay care if it spreads quickly. Keep any wound clean and follow instructions for dressings.

Contact a clinician promptly if redness is spreading, pain is intensifying, swelling is increasing, or you are not improving as expected. Seek urgent care for fever, confusion, faintness, severe weakness, rapidly worsening symptoms, or cellulitis near the eye. People with conditions that affect immunity or circulation may need earlier review.

Ask which antibiotic route is appropriate, when you should expect the redness and pain to begin settling, and what changes mean the plan needs review. Ask whether an entry wound, ulcer or swelling needs separate treatment.
