Antibiotic treatment for folliculitis

A clinician may use a topical antibiotic for a limited bacterial eruption and consider an oral antibiotic when affected areas are more extensive, deep or difficult to control. Antibiotics do not treat folliculitis caused by yeast, irritation or some other non-bacterial triggers.

Folliculitis is inflammation around hair follicles and often produces small red or pus-filled bumps. Similar-looking eruptions can arise after shaving, friction, hot-tub exposure, yeast overgrowth or ingrown hairs, so appearance alone may not identify the cause.

The prescriber considers the body site, whether bumps are superficial or forming deeper tender lumps, how widely they have spread and whether treatment has already failed. Recurrent or persistent cases may need a swab or another examination to guide therapy rather than repeated use of an unsuitable antibiotic.

Use the prescribed antibiotic exactly as labelled and complete the advised course unless the treating clinician changes the plan. Apply topical medicine only to the instructed area, wash your hands before and after, and avoid sharing towels or razors while lesions are active. Do not squeeze or pick the bumps because this can worsen inflammation and spread infection.

Pause shaving over irritated skin and reduce rubbing from tight clothing or equipment. A warm, clean compress may ease tenderness and encourage superficial drainage. Seek advice before adding antiseptics, acne products or leftover antibiotics, since these may irritate the skin or target the wrong cause.

Arrange prompt assessment if redness is expanding, pain or swelling is increasing, pus is collecting in a larger lump, or fever and chills develop. Infection near the eyes or rapidly worsening facial swelling also needs urgent attention.

Contact the prescriber if new lesions continue to appear during treatment, the eruption returns soon afterward, or the medicine causes hives, facial swelling, breathing difficulty, severe diarrhoea or a widespread rash. Breathing difficulty or swelling of the lips or tongue requires emergency help.

Ask what suggests a bacterial cause, whether a swab is useful, and why topical or oral treatment suits your pattern. Clarify how to apply or take the medicine, what improvement should look like, which adverse effects require action and how shaving or skin care should change during recovery.
