Which oral antibiotic with activity against MRSA is commonly used for furuncles and carbuncles (abscess)?

Explanation:
When treating furuncles or carbuncles presumed to involve MRSA, the goal is an oral antibiotic that reliably covers MRSA and penetrates skin and soft tissue well, since drainage is essential and antibiotics are an adjunct. Clindamycin fits these needs: it has good oral bioavailability and penetrates skin and soft tissue effectively, and provides reliable MRSA coverage for common community-associated strains. It also covers anaerobes, which can be present in abscess cavities, offering practical coverage for the infection site. Amoxicillin wouldn’t work against MRSA, erythromycin often has resistance among MRSA strains, and while doxycycline can cover MRSA, clindamycin is a more commonly used option for this presentation.
