When a patient has a true penicillin allergy, clindamycin is a go-to alternative because it has good activity against the typical oral pathogens involved in odontogenic infections, including anaerobes and viridans-group streptococci, and it penetrates bone and soft tissue well. This makes it effective for dental infections in those who cannot take beta-lactams. It’s not primarily chosen for penicillin intolerance (non-allergic reactions), since the scenario hinges on an immune-mediated allergy. Keep in mind clindamycin’s association with C. difficile risk, which is why it’s reserved for those with true penicillin allergy rather than broad, unnecessary use.
