What Antibiotics Are Used to Treat Skin Infections? A Complete Skin Infection Antibiotic Guide

Supportive Care and Prevention

• Clean minor wounds with mild soap and water and cover them with a clean bandage.
• Do not squeeze or pop boils; this can push bacteria deeper.
• Elevate an affected arm or leg to reduce swelling.
• Wash hands often and avoid sharing towels, razors or athletic gear.
• Manage athlete's foot, eczema and dry cracked skin, which are common entry points.
• Photograph the redness edge, or mark it, to track whether it is spreading.

Frequently Asked Questions About Antibiotics for Skin Infections

1. What is the best antibiotic for cellulitis?

There is no single best choice. Most non-purulent cellulitis is caused by streptococci, so prescribers often start with cephalexin, dicloxacillin or penicillin, or clindamycin for penicillin allergy. If MRSA is suspected, doxycycline or trimethoprim-sulfamethoxazole may be added. Your clinician decides based on your exam, history and local resistance patterns.

2. Which antibiotics treat MRSA skin infections?

Oral options commonly include trimethoprim-sulfamethoxazole, doxycycline, clindamycin (if the strain is susceptible), and linezolid. Severe cases need IV therapy such as vancomycin. Draining an abscess is often the most important step, and culture results help guide the drug.
