Preseptal cellulitis antibiotic treatment: what to know

Preseptal cellulitis affects the eyelid and nearby skin in front of the eye socket. It can cause redness, warmth, swelling, tenderness and fever. A clinician decides whether tablets are suitable or whether treatment in hospital is safer, based on age, overall health, severity and ability to take medicine. Antibiotics should be taken exactly as directed; do not share leftover medicine or use drops without advice. Improvement may take time, but worsening swelling or new eye symptoms need reassessment.

Arrange same-day medical advice if this infection is suspected. Take the full prescribed course unless the prescriber changes it, and tell the clinician about allergies, pregnancy, other medicines and immune problems. Keep the area clean, avoid squeezing the eyelid, and do not wear contact lenses until a clinician says it is safe. A cool clean compress may ease discomfort, but it does not replace antibiotics.

Seek emergency care for pain when moving the eye, reduced or double vision, a bulging eye, severe headache, marked drowsiness, vomiting, or rapidly increasing swelling. These features can indicate infection deeper in the eye socket. Seek prompt review if fever persists, redness spreads, the person cannot take the medicine, or symptoms are not improving as expected.

Ask which antibiotic was chosen, how often to take it, what improvement should look like, and which symptoms mean you should return immediately. Confirm whether follow-up is needed and when contact lenses or usual eye products can be restarted.
