From the Guidelines
Periorbital cellulitis treatment requires prompt medical attention and typically involves antibiotics targeting common causative organisms like Staphylococcus aureus and Streptococcus species. For mild cases, oral antibiotics such as amoxicillin-clavulanate (875/125 mg twice daily for 5 days) are recommended, as stated in the 2014 update by the Infectious Diseases Society of America 1. In cases of severe periorbital cellulitis, hospitalization for intravenous antibiotics such as ampicillin-sulbactam (3 g every 6 hours) or ceftriaxone (1-2 g daily) plus vancomycin (15-20 mg/kg every 12 hours) may be necessary, especially if there are signs of systemic infection or if the patient is not responding to oral antibiotics 1. Some key points to consider in the treatment of periorbital cellulitis include:
- Monitoring for complications such as orbital cellulitis, which presents with eye movement pain, proptosis, or vision changes 1
- Supportive measures including warm compresses, elevation of the head, and pain management
- Addressing underlying causes, such as adjacent sinusitis, which is a common cause of periorbital cellulitis 1
- Surgical drainage may be necessary if an abscess is present
- Follow-up within 24-48 hours is important to ensure improvement, with longer courses of antibiotics sometimes needed based on clinical response 1. It's also important to note that the treatment should be tailored to the individual patient's needs and the severity of the infection, and that the recommended duration of antimicrobial therapy is 5 days, but treatment should be extended if the infection has not improved within this time period 1.
