Clindamycin Dosage and Administration Guidelines

Adult Dosing

• The Infectious Diseases Society of America recommends 600 mg IV/PO three times daily for skin and soft tissue infections, pneumonia, and bone and joint infections, including osteomyelitis and septic arthritis 2
• For particularly severe infections requiring IV therapy, 600-900 mg every 6-8 hours is recommended 1
• For pelvic inflammatory disease, 900 mg IV every 8 hours is typically used, often in combination with gentamicin 1

Pediatric Dosing

• For MRSA infections, the Infectious Diseases Society of America recommends 10-13 mg/kg/dose IV/PO every 6-8 hours, not to exceed 40 mg/kg/day 2, 1
• For oral administration in pediatric MRSA infections, 30-40 mg/kg/day divided into 3-4 doses is typically used 1
• For Group A Streptococcal infections, oral clindamycin can be administered at 40 mg/kg/day in 3 doses 1
• For dental infections in children, 30-40 mg/kg/day in 3-4 divided doses is recommended 3

Duration of Therapy

• For pneumonia, treatment duration ranges from 7-21 days, depending on the extent of infection 1
• For bacteremia and endocarditis, duration of therapy may range from 2-6 weeks depending on the source and presence of endovascular infection 1
• For osteomyelitis, a minimum 8-week course is recommended 1
• For most infections, IV therapy should continue for at least 48 hours after clinical improvement before transitioning to oral therapy 1

Pathogen-Specific Considerations

• For serious anaerobic infections, IV clindamycin is often preferred initially, with transition to oral therapy after clinical improvement 1
