Patients with periorbital cellulitis with concurrent sinusitis or risk factors for Haemophilus influenzae type b infection

For factors influencing the choice of antibiotic therapy for periorbital (preseptal) cellulitis see Approach to managing periorbital (preseptal) cellulitis.

For patients with periorbital cellulitis who are systemically unwell and have concurrent sinusitis or risk factors for Haemophilus influenzae type b (Hib) infection (eg children younger than 5 years who are not fully vaccinated), follow management of orbital cellulitis.

In confirmed cases of Hib infection, clearance antibiotics with or without immunisation may be required for the patient and close contacts; see Clearance antibiotics for invasive meningococcal or Hib disease.
