FDA Did Not Change Position on Ivermectin Use, Contrary to Online Claims


SciCheck Digest

In response to a civil suit, lawyers for the Food and Drug Administration described the agency’s warnings about the unapproved use of ivermectin to treat COVID-19 as “recommendations.” Although that description doesn’t reveal new information, some conservative outlets have falsely claimed it’s an “outrageous” revelation and a change in the FDA’s position.

Full Story

The number of ivermectin cases reported to poison control centers increased markedly in the summer of 2021, as peddlers of medical misinformation promoted its use as a treatment for COVID-19 despite a lack of evidence and advice to the contrary from public health agencies.

As we’ve explained, ivermectin is approved for human use as an anti-parasitic drug and is also widely available in different formulations for veterinary use.

In March 2021, however, the Food and Drug Administration said that it had “received multiple reports of patients who have required medical support and been hospitalized after self-medicating with ivermectin intended for horses.”

The FDA explained that using drugs that haven’t been approved to treat a particular disease “can cause serious harm.” The agency described some of the potential consequences of unauthorized ivermectin use, specifically warning about the highly concentrated versions of the drug made for horses.

But by the summer of 2021, ivermectin had been embraced in an increasingly politicized response to the pandemic, with conservative politicians and groups promoting the drug.

From early July through mid-August 2021, prescriptions for ivermectin had reached a 24-fold increase over pre-pandemic levels, according to the Centers for Disease Control and Prevention. The National Poison Data System recorded an eightfold increase in reported ivermectin cases from August 2020 to August 2021.

On Aug. 21, 2021, the FDA tweeted a link to its webpage about ivermectin and COVID-19 — which was titled “Why You Should Not Use Ivermectin to Treat or Prevent COVID-19” — and included this message: “You are not a horse. You are not a cow. Seriously, y’all. Stop it.”

That tweet is now the focus of a lawsuit brought by three doctors who have advocated the use of ivermectin. They argue that federal agencies interfered with their ability to practice medicine by publishing advisories against the use of ivermectin to treat COVID-19.

Doctors commonly prescribe medications for off-label uses, and, in this case, the plaintiffs argued that the FDA’s posts about using ivermectin to treat COVID-19 essentially limited their ability to prescribe it for that purpose.

The doctors — one of whom is an ear, nose and throat doctor who was suspended from practicing at a Houston hospital after she refused to take on new patients who had been vaccinated against COVID-19 — have received support from America’s Frontline Doctors, a group that has peddled false information about the pandemic.

The Epoch Times — a conservative media outlet owned by a Chinese religious group — published a story on Nov. 19 about a recent court hearing in the case with the headline: “FDA Says Telling People Not to Take Ivermectin for COVID-19 Was Just a Recommendation.”

The conservative website the Gateway Pundit picked up the claim and took it a step further, posting a headline that said: “Outrageous! FDA Backtracks During Trial and Now Claims ‘Not Taking Ivermectin for COVID-19’ was Merely a Recommendation.”

Social media users have shared screenshot memes of those headlines with comments such as, “LOCK THEM UP!” (The doctors’ lawsuit is civil, not criminal. So, regardless of the outcome, nobody is going to be locked up.)

But, contrary to the online backlash, the FDA’s description of its online posts as “recommendations” doesn’t reveal anything new.

The headlines are based on arguments made during a hearing for the FDA’s motion to dismiss the case.

“The cited statements simply communicated FDA’s recommendations regarding the use of ivermectin to prevent or treat COVID-19,” lawyers representing the FDA wrote in their motion to dismiss the case. “They ‘neither require[d] nor forb[ade] any action on the part of’ Plaintiffs or anyone else.”

The FDA’s lawyers also pointed out that although the doctors bringing the case allege that the statements interfered with their ability to practice medicine, the doctors also said that they continued to prescribe ivermectin for COVID-19 patients despite the FDA’s online posts.

The FDA’s description in court of its posts as recommendations didn’t constitute a change in the administration’s position.

We’ve written before about how partisans and misinformation peddlers twist or misrepresent statements from public health officials in an effort to make it seem like something nefarious happened.

The FDA’s website still explains why people shouldn’t use ivermectin as a COVID-19 treatment, and the National Institutes of Health recommends against its use for the disease, except for clinical trials.

As we’ve explained, randomized clinical trials have repeatedly found that ivermectin does not benefit COVID-19 patients.
