EP: 4.Exploring the Anti-Inflammatory Impact of Oral Antibiotics

When identifying which patients are best suited for oral antibiotics in acne treatment, clinical presentation serves as a key guide. Patients typically fall into 3 categories: those with mild acne that can be managed effectively with topical therapies; those with severe nodulocystic or scarring acne, for whom isotretinoin is often the first-line option; and those in the moderate to moderately severe category, who often benefit from oral antibiotics. The middle group—patients with inflammatory papules or more persistent breakouts—is particularly responsive to a short course of antibiotics as part of an initial, intensive treatment phase.

The goal of prescribing oral antibiotics in these cases is to achieve rapid and visible improvement within a defined period, usually 3 months. This “knockout phase” is followed by a tapering strategy that transitions patients to topical maintenance therapy, thereby limiting prolonged antibiotic exposure. Occasionally, the antibiotic phase may be extended up to 6 months, depending on individual response. Narrow-spectrum agents, such as sarecycline, have supporting data for longer-term safety, including one-year studies in pediatric populations. However, stewardship principles generally favor limiting use to the shortest effective duration and transitioning to alternative therapies if progress plateaus.

If a patient does not achieve sustained improvement after the initial antibiotic course, the treatment plan is reevaluated. For persistent or more treatment-resistant acne, systemic options such as isotretinoin are commonly employed. In certain cases—particularly in female patients—hormonal agents such as spironolactone may be considered. The approach remains individualized, with a focus on achieving clear skin efficiently while minimizing long-term antibiotic use. The ultimate objective is not just control, but durable resolution, enabling patients to move beyond the burden of chronic acne.
