Don’t take Horse Dewormer

Obviously as skeptics we’re pretty clued up on the idea of not using unproven therapies, especially when there’s positive evidence that they don’t work. It’s been apparent for a while now that the evidence for Ivermectin as a COVID treatment or preventative is not very good, and it’s been sad to see how many people don’t seem to care.

There’s been so much in the news about Ivermectin recently, given that it seems to have really reached a tipping point for those who are looking for an alternative to masks, vaccines, and other science based answers to our pandemic, that I figured I’d just summarise the news with a paragraph or so for each of a few stand out stories:

Joe Rogan, an influential podcaster who hosts a popular podcast on Spotify, has contracted COVID and has said on his podcast that he’s taking Ivermectin. However, he’s also taking monoclonal antibodies, prednisone, a NAD drip and a vitamin drip, some of which might actually be effective in helping him fight the virus. My money is on Joe proclaiming Ivermectin to be a miracle drug once he’s beaten the virus, but I think it’s worth heeding Joe’s own words when it comes to whether we should trust anything he says:

"I’m not a doctor, I’m a fucking moron, and I’m a cage-fighting commentator who’s a dirty stand-up comedian... I’m not a respected source of information - even for me."

Merck Sharp & Dohme, who sell Ivermectin in New Zealand under the name Stromectol, reported (opens new window) that they have been seeing "unusually high buying patterns" of Ivermectin recently. Medsafe has also reported an increase in attempts to import Ivermectin - 100 of 114 consignments of Ivermectin destined for New Zealand this year have been turned away by Customs after consulting with Medsafe.

Ivermectin poisonings in the US are on the increase, as an inevitable result of both an explosion in use of the drug (opens new window) and a large number of people self-medicating. The National Poison Data System reports that the number of "exposure cases" has jumped in the last month, and a lot of this is coming from people who have been buying a version of Ivermectin which is formulated for treating animals rather than humans. However, as skeptics we should always be wary of false news, even when it fits our existing narrative - and in this case it turns out that the recent report from a doctor (opens new window) in Oklahoma that hospitals are turning away gunshot victims because of the lack of beds due to the sheer number of Ivermectin poisonings is false. The local health system has said:

"Dr. McElyea has not worked at our Sallisaw location in over 2 months. NHS Sequoyah has not treated any patients due to complications related to taking ivermectin. This includes not treating any patients for ivermectin overdose. All patients who have visited our emergency room have received medical attention as appropriate. Our hospital has not had to turn away any patients seeking emergency care."

One change I’ve been happy to see recently is the number of news agencies who have moved from just using the drug’s name, Ivermectin, to naming the formulation that many people in the US and elsewhere are buying - horse dewormer. As much as this might feel like a low blow, I feel that if talking about horse dewormer causes some people who were previously unsure about taking this medicine to steer clear of it in the context of COVID, that’s a good thing.

Of course, all of this is not to say that Ivermectin isn’t a useful drug - it absolutely is. The discoverer of Ivermectin was awarded a Nobel prize in 2015 for his work, and the drug is listed by the World Health Organisation as an Essential Medicine (opens new window) for humans. But taking it for a condition where there’s no evidence it will help, and a clear risk of dangerous side effects, is not a good idea.

I’ll leave the last word to the US Food and Drug Administration, who said on twitter a couple of weeks ago:
