In this episode of Tea with Dr. D, host James Q. Del Rosso delivers a solo “Spilling the Tea” segment that revisits oral isotretinoin through a longitudinal lens, connecting its early clinical foundations to present-day practice.  

Framing isotretinoin as a “winding road,” Dr Del Rosso reflects on its 1982 approval, early safety observations, and the evolution of risk management strategies, including the iPLEDGE program. While concerns around psychiatric effects, inflammatory bowel disease, and teratogenicity have shaped prescribing behaviors, he emphasizes that most patients tolerate therapy well when appropriately monitored.  

A central theme is the value of foundational knowledge. Dr Del Rosso highlights considerations that remain highly relevant, including dosing flexibility, relapse patterns, treatment duration, and importantly, the impact of absorption on outcomes. Conventional formulations require adequate dietary fat for optimal bioavailability, and suboptimal fat intake may contribute to perceived treatment failure or relapse.  

He also reviews evolving data on dosing strategies, noting that a range of daily doses can achieve clearance. The priority, however, is durability of response. Clinicians are encouraged to focus on cumulative exposure and to individualize therapy, extending duration or adjusting dose as needed to maintain clearance. Newer formulations, including lidose and micronized isotretinoin, may help mitigate variability in absorption and improve consistency, though access and cost remain considerations.  

Additional insights address relapse risk and the importance of evaluating possible underlying contributors such as androgen excess. Laboratory monitoring practices have also evolved, with a more streamlined approach focusing on key parameters like liver enzymes and triglycerides, alongside strict adherence to pregnancy prevention protocols.  

Ultimately, the episode reinforces that while isotretinoin prescribing has modernized in certain respects, many core principles remain unchanged. Thoughtful dosing, attention to absorption, and individualized management are essential to optimizing long-term outcomes.

Tune in to the episode to revisit the clinical foundations of isotretinoin, refine your approach to dosing and duration, and learn practical strategies for improving treatment consistency and long-term acne clearance.
