Uses and warnings
Boxed Warning: Clostridium difficile-associated diarrhea (CDAD) ranging from mild diarrhea to fatal colitis has been reported. The drug alters normal colon flora, risking C. difficile overgrowth. "CDAD must be considered in all patients who present with diarrhea following antibiotic use," even occurring over two months after therapy ends. Additional warnings include severe skin reactions (including fatal cases), contraindication in meningitis (inadequate CSF penetration), and caution in patients with gastrointestinal disease or hepatic/renal impairment.
Clindamycin treats serious infections caused by susceptible bacteria, including anaerobes, streptococci, pneumococci, and staphylococci. Use should be reserved for penicillin-allergic patients or when penicillin is inappropriate. Specific indications include respiratory tract infections, skin and soft tissue infections, septicemia, intra-abdominal infections, and pelvic/genital infections. "Bacteriologic studies should be performed to determine the causative organisms and their susceptibility."
