Background
- Adverse reaction to β-lactam antibiotics occurring in about 1 to 10% of prolonged courses
- Higher risk with penicillin G, nafcillin, oxacillin, piperacillin-tazobactam, ceftriaxone, and ceftaroline
- Risk increases with cumulative exposure
- Mechanism is unclear; may be some combination of a direct toxic effect or an immune-mediated hypersensitivity reaction
Clinical Manifestations
- Neutropenia
- Can progress to agranulocytosis
Management
- Stop the offending agent
- Other β-lactam antibiotics are probably still safe to use
