Can pediatric preseptal cellulitis be treated with Bicillin (Benzathine penicillin G) intramuscularly (IM) due to concerns about the patient's ability to comply with oral antibiotics?

From the Guidelines

Bicillin (benzathine penicillin G) IM is not recommended as first-line treatment for pediatric preseptal cellulitis due to its limited spectrum of activity against common causative organisms, as stated in the guidelines for skin and soft-tissue infections 1. Preseptal cellulitis is typically caused by Staphylococcus aureus (including MRSA) and Streptococcus species, and requires broader coverage than Bicillin provides. For patients with compliance concerns, more appropriate options include:

• ceftriaxone IM (50-75 mg/kg/day)
• clindamycin (if MRSA is suspected) administered in a monitored setting. Alternatively, consider directly observed therapy with oral antibiotics like:
• amoxicillin-clavulanate (40 mg/kg/day divided twice daily)
• trimethoprim-sulfamethoxazole or clindamycin, if MRSA is a concern. Preseptal cellulitis requires prompt and effective treatment to prevent progression to orbital cellulitis, which can threaten vision and cause serious complications, as emphasized in the practice guidelines for the diagnosis and management of skin and soft tissue infections: 2014 update by the infectious diseases society of america 1. If compliance remains a significant concern, hospitalization for IV antibiotics may be necessary, especially for younger children or those with more severe presentations. Close follow-up within 24-48 hours is essential to ensure clinical improvement, and therapy for typical cases of cellulitis should include an antibiotic active against streptococci, with a 5-day course of antimicrobial therapy being as effective as a 10-day course, if clinical improvement has occurred by 5 days 1.

From the Research

Treatment Options for Pediatric Preseptal Cellulitis

• The use of Bicillin IM for treating pediatric preseptal cellulitis due to concerns about patient compliance with oral antibiotics is not directly addressed in the provided studies 2, 3, 4, 5, 6.
• However, the studies suggest that intravenous antibiotics are often used in the treatment of preseptal cellulitis, especially in cases where there are concerns about patient compliance or the severity of the infection 3, 4, 6.
• One study found that ambulatory intravenous antibiotics with daily review are a safe and cost-effective alternative to inpatient admission for children with preseptal cellulitis who require parenteral antibiotics 3.
• Another study emphasized the importance of optimizing antibiotic dosing to achieve pharmacodynamic target attainment and transitioning from intravenous to oral therapy when possible 4.
• The choice of antibiotic and duration of therapy may vary depending on the severity of the infection and the presence of underlying conditions such as sinusitis or dental abscess 5, 6.

Antibiotic Therapy for Preseptal Cellulitis

• The studies suggest that antibiotics such as ampicillin-sulbactam, ceftriaxone, and clindamycin are often used in the treatment of preseptal cellulitis 4, 5, 6.
• The duration of antibiotic therapy for preseptal cellulitis is typically around 2 weeks, although this may vary depending on the severity of the infection and the presence of underlying conditions 4, 5, 6.
• The use of corticosteroids in the treatment of preseptal cellulitis is controversial, and their use may vary depending on the severity of the infection and the presence of underlying conditions 5, 6.

Patient Compliance and Treatment Outcomes

• Patient compliance with oral antibiotics is an important consideration in the treatment of preseptal cellulitis, and alternative treatment options such as intravenous antibiotics may be necessary in cases where compliance is a concern 2, 3, 4.
• The studies suggest that prompt initiation of intravenous antibiotics is mandatory in the treatment of preseptal cellulitis, and that early treatment can help prevent complications and improve treatment outcomes 3, 4, 6.
