When is antibiotics for skin infection recommended for cellulitis?

Cellulitis affects deeper layers of skin and can cause warmth, tenderness, swelling, and redness that expands beyond the original break in the skin. A clinician checks how quickly it is spreading, whether there is pus or an abscess, and whether fever or other whole-body symptoms are present. Treatment may be by mouth or through a vein when illness is severe, the infection is extensive, or oral treatment cannot be used.

Seek medical assessment promptly rather than waiting for the redness to resolve on its own. Keep the area clean, avoid rubbing it, and elevate an affected limb when comfortable. Marking the edge of redness can help show whether it is expanding, but it does not replace review. Take antibiotics exactly as prescribed and contact the clinician if symptoms worsen or fail to begin settling.

Seek emergency care for severe pain, rapidly spreading redness, red or purple skin, blistering, fever with shaking chills, confusion, faintness, or difficulty breathing. Urgent review is especially important when cellulitis affects the face or eye area, follows an animal or human bite, or occurs in someone with reduced immunity.

Ask what features support cellulitis, whether an abscess or wound needs separate treatment, which antibiotic plan is suitable, and when improvement should be checked. Discuss allergies, previous resistant infections, diabetes, immune conditions, and medicines that may affect treatment.
