T Watson, C Robertson. NEJM 2023; 389; 25: 2312-2314. Silencing the FDA’s Voice — Drug Information on Trial
Recently (9/1/23), “a panel of the Fifth Circuit Court of Appeals allowed a case to proceed against the Food and Drug Administration (FDA) concerning its public statements on the use of ivermectin for treating Covid-19.1“ Even though a district court had dismissed the suit due to “sovereign immunity,” the Fifth Court stated the FDA had exceeded its authority.
Some excerpts from this commentary:
Between August 2021 and April 2022, however, the agency released several public messages about ivermectin and Covid-19 — including an informal consumer update titled “Why You Should Not Use Ivermectin to Treat or Prevent COVID-19”…
Three physicians who prescribed and promoted ivermectin for Covid-19 treatment sued the FDA, alleging that its statements interfered with their ability to practice medicine and harmed their professional reputations, even though they hadn’t been named by the FDA. One doctor claimed the agency’s statements had caused him to be referred to his state medical board; the others claimed to have lost admitting privileges at a hospital and a role at a medical school.
According to the Fifth Circuit, the FDA “has authority to inform, announce, and apprise — but not to endorse, denounce, or advise”….
The Fifth Circuit panel’s opinion is puzzling in light of the FDA’s long-standing and generally unquestioned role as a public health educator. The agency routinely releases consumer-directed information; for example, its website instructs consumers about the appropriate use of antibiotics and includes related clinical information. The opinion suggests the FDA may need to reevaluate each of these communications — an impractical proposition.
The opinion is also in tension with a long-standing constitutional principle known as the government speech doctrine, according to which the government can itself be a speaker, like any person or corporation, and isn’t required to be neutral when it expresses an opinion..
The Fifth Circuit’s holding reflects suspicion of agency influence, even in matters in which the agency is an expert speaking directly about products it regulates. The court’s interpretation of the FDA’s proper role may permit only narrow forms of expression...
Subsequent courts could use the Fifth Circuit’s logic to disempower other agencies with health-related missions, such as the Centers for Disease Control and Prevention and the Environmental Protection Agency… Meanwhile, “junk science” pervades social media and harms public health.2
My take: It is hard to believe that the justification for this challenge comes from three physicians prescribing ivermectin. It turns out the FDA’s advice was spot on and that these physicians were offering an ineffective therapy. This is a worrisome trend in which the judicial branch seeks
- To limit government agencies without explicit line-by-line authorization by a dysfunctional congress
- And to substitute its judgement over matters in which it has little expertise over governmental agencies tasked with protecting our country (eg. FDA, CDC, EPA, and others)
