This commentary examines early penicillin use in the 1940s, when physicians treated severe pneumococcal pneumonia with much shorter courses and lower doses than currently prescribed. Despite these limited regimens, which were partly necessitated by drug scarcity, treatment outcomes were successful. The article raises fundamental questions about optimal antibiotic treatment duration that remain relevant today.
Why it matters
This historical perspective challenges current assumptions about antibiotic treatment duration and dosing. Understanding that shorter courses were effective in the past may inform efforts to optimize antibiotic stewardship, reduce resistance, and minimize unnecessary treatment in modern medicine.
Understand the Science
When penicillin first entered hospital wards in the 1940s, its use was essentially treatment through experimentation. Early publications were case series by clinicians learning by doing, describing their experience in detail for the knowledge of other physicians and the benefit of their patients. They treated even severe pneumococcal pneumonia for only a few days and with much lower doses than we use today.1–3 Although these regimens were dictated as much by scarcity as by principle, they were successful.
