What should you know about strongest antibiotic for skin infection?

A skin infection may involve hair follicles, a collection of pus, or deeper spreading tissue. Folliculitis can need a different approach from Cellulitis, and a Boil may need drainage rather than an antibiotic alone. The clinician considers the appearance, body site, speed of change, fever, immune health, allergies, pregnancy, kidney function, and recent antibiotic use. Some rashes that look infected are inflammatory or viral, so an antibiotic would not address the cause.

Have a spreading, painful, warm, or draining area assessed rather than choosing a medicine from a leftover supply. Use only the prescribed dose and schedule, complete the course unless the prescriber changes it, and report a severe reaction such as facial swelling or breathing difficulty immediately. Keep draining areas covered with clean dressing, wash your hands, and avoid squeezing a Boil.

Seek urgent care for rapidly expanding redness, severe pain, red streaks, high Fever, confusion, faintness, or marked weakness. Same-day assessment is appropriate for infection near the eye, a large painful collection, tissue that turns dark, or symptoms in someone with reduced immunity. A clinician may need to drain an abscess, collect a sample, or use treatment through a vein.

Ask whether the problem is Folliculitis, Cellulitis, a Boil, or another condition; whether drainage or a sample is needed; and what improvement and side effects should prompt a review.
