Podcast: How to Prescribe Off-Label With Henry Nasrallah, MD

Joseph F. Goldberg, MD, in this installment of "Brain Trust: Conversations in Psychopharmacology," sits down with Henry Nasrallah, MD, to discuss off-label prescribing and polypharmacy.

Nasrallah bases the discussion off his landmark analysis that demonstrated 88% of DSM psychiatric diagnoses have no US Food and Drug Administration (FDA)-approved pharmacotherapy, leaving clinicians with no choice but to prescribe off-label for many of the patients they encounter. He argues that the FDA's diagnosis-centric approval framework, rather than a symptom- or circuit-based model, is a primary driver of this gap, noting that a shift toward symptom-level indications could render irrelevant much of current off-label practice.

Both clinicians emphasize that off-label prescribing, when rationale-based and neuroscientifically informed, constitutes responsible clinical care rather than reckless deviation. Nasrallah describes examples like using valproate for impulsive aggression in traumatic brain injury, clozapine augmentation for treatment-resistant suicidality, and high-dose modafinil for refractory depression—each grounded in mechanistic reasoning. Goldberg observes that "off-label practices are legitimate…good for patients and save a lot of lives," while cautioning that prescribers must understand what a drug does in the brain, not merely follow or ignore labeling.

The conversation also addresses the transdiagnostic model, polypharmacy, insurance barriers to off-label coverage, and the underutilization of clozapine. Nasrallah concludes by characterizing off-label discovery as "a creative process, the cutting edge of scientific advances," urging clinicians to publish case reports and share serendipitous findings to catalyze future trials.
