Nasal furunculosis antibiotics: what to know

Furunculosis describes boils caused by infection around a hair follicle. Inside the nose, the area may be tender, swollen, red, or crusted, and touching or squeezing it can worsen irritation. A local infection may spread into nearby skin, causing cellulitis. The condition itself does not determine which antibiotic is needed; the choice depends on examination, severity, allergies, previous treatment, and local prescribing guidance.

Arrange a medical review rather than squeezing, piercing, or picking the boil. Keep hands clean, avoid sharing towels, and do not put unprescribed creams or household products inside the nose. If an antibiotic is prescribed, take it exactly as directed and complete the course unless the prescriber changes the plan. Report diarrhoea, rash, swelling, or breathing difficulty promptly. A clinician may consider local treatment, drainage, or a swab as well as tablets.

Seek prompt care if swelling or redness is spreading, pain is increasing, fever develops, or the nose or face becomes markedly swollen. Urgent help is needed for swelling near the eye, vision changes, severe headache, confusion, or feeling seriously unwell. People with diabetes, reduced immunity, or recurrent boils should seek advice early because infections may need closer monitoring.

Does this look like a furuncle, cellulitis, or another lesion? Do I need an antibiotic, drainage, or a swab? Which symptoms would mean the infection is spreading, and how should recurrence be prevented?
