Objective: To systematically review the rationale, evidence, and strategies for using combination drug therapy in the management of deep pyodermas, particularly in the context of antimicrobial resistance (AMR) and disease recurrence. Methodology: A comprehensive literature review was performed using PubMed/MEDLINE, Embase, and the Cochrane Library for articles published between 2000 and 2024. Search terms included "deep pyoderma," "furuncle," "carbuncle," "hidradenitis suppurativa," "MRSA," "combination therapy," and "decolonization." This review synthesizes findings from clinical trials, meta-analyses, and expert guidelines. Key Findings: Monotherapy for deep pyodermas is increasingly inadequate. The role of combination therapy is multi-faceted: 1) To provide adequate empirical coverage against MRSA (e.g., TMP-SMX + cephalosporin); 2) To enhance bactericidal activity and prevent resistance (e.g., adding Rifampicin to Clindamycin or Doxycycline); 3) To manage the significant inflammatory component (e.g., antibiotics + NSAIDs or biologics in hidradenitis suppurativa); and 4) To eradicate carriage and prevent recurrence (e.g., systemic antibiotics + topical decolonization with mupirocin and chlorhexidine). Evidence strongly supports combination approaches for recurrent furunculosis and is the standard of care for moderate-to-severe hidradenitis suppurativa. Conclusion: The management of deep pyodermas has evolved from simple antimicrobial monotherapy to a complex, strategic combination approach. The modern therapeutic goal is not just to cure the acute infection, but to manage inflammation, overcome AMR, and disrupt the cycle of recurrence. Clinical strategy requires a personalized combination of systemic antibiotics (often dual), targeted anti-inflammatories, and aggressive decolonization.
