Ivermectin and COVID-19: Why poison centers are getting calls about this controversial drug
Is this a miracle pill or a sham?
Since the start of the COVID-19 pandemic, some medical professionals have reviewed already available drugs to see if they could be used as effective treatments. Ivermectin, an anti-parasitic, was administered to some patients across the globe, with seemingly positive effects. However, more studies show it has little to no effect when it comes to treating COVID-19. There’s also been an increase in calls to poison centers by people who are taking ivermectin intended for animals.
On one side, there are doctors who say ivermectin could help end the pandemic if used globally. On the other are public health officials who have reviewed the data and say the drug’s effectiveness against COVID-19 isn’t conclusive.
Here’s everything you need to know about ivermectin and its use for COVID-19.
What is ivermectin?
Ivermectin is an anti-parasitic medicine «that works by altering cellular channels,» said Dr. Soumi Eachempati, CEO of Cleared4 and former professor of surgery and public health at Weill Cornell Medical College. The drug inhibits some viruses from infecting cells, thus preventing the virus from spreading. Ivermectin is usually given to treat parasitic infections like lice and Strongyloides, according to Eachempati.
Scientists at pharmaceuticals giant Merck discovered ivermectin in 1975 and began to use it to treat scabies, river blindness and other parasitic diseases carried by worms and lice starting in 1981. It’s on the World Health Organization’s list of essential medicines for a basic health care system. More than 250 million people take the drug across the globe each year, and it’s effective for animals as well.
The drug is considered safe when taken in appropriate dosages. Side effects for the ivermectin vary depending on whether it’s taken orally to treat intestinal infections or topically for skin infections. Oral tablets can cause drowsiness, nausea, vomiting and, in very rare cases, an increase in heart rate and seizures. Side effects for the topical ivermectin can include skin rash and irritation, while dry skin and stinging pain are severe and rare.
Can ivermectin be used to cure COVID-19?
This is where things get complicated. Public health agencies, including the Federal Drug Administration, the National Institutes of Health and the World Health Organization, don’t suggest ivermectin’s use to treat COVID-19. They cite the lack of data from large, randomized trials confirming the drug’s effectiveness to treat the disease.
Doctors who cited multiple smaller studies and firsthand experience say otherwise. They claim ivermectin does work to prevent people from developing symptoms from COVID-19 and can shorten recovery time for those already infected.
What do the public health agencies say about ivermectin use for COVID-19 treatment?
The FDA said in March it hasn’t approved the use of ivermectin to treat COVID-19. It warned that large doses of the drug are «dangerous and can cause serious harm.» The agency also advised against human use of ivermectin produced for animals, such as cows and horses, as the doses aren’t the same and could contain ingredients intended only for animals.
A growing number of people have been taking ivermectin for animals as word’s spread on social media about its possible use against COVID-19. This has resulted in some people calling state poison centers after taking the drug, since the medication is intended for animals. On Aug. 20, the Mississippi State Department of Health sent out an alert regarding the number of calls its poison center received, with 70% related to the «ingestion of livestock or animal formulations of ivermectin purchased at livestock supply centers.»
In April, the FDA reaffirmed in a post on its website that ivermectin isn’t approved to treat COVID-19 nor has it been given emergency use authorization.
The NIH said in February there was insufficient data to «recommend either for or against the use of ivermectin for the treatment of COVID-19.» It did say lab tests found the drug stopped the reproduction of the SARS-CoV-2 virus that cause the disease. However, to be effective, the dosages would need to be «100-fold higher than those approved for use in humans.»
While some clinical studies showed ivermectin to have no benefit, the NIH said others saw a lower mortality rate among patients. However, those studies were incomplete or had methodological limitations such as small sample sizes or patients receiving additional medicine along with ivermectin, according to the NIH.
The WHO said in March the current evidence on the use of ivermectin for treatment of COVID-19 was «inconclusive.»
A doctor in Arkansas who prescribed the drug to patients is under investigation by the state medical board, according to a report from CNN. He reportedly gave ivermectin prescriptions to prisoners at the county jail where he was contracted to provide medical services.
Who says ivermectin is a treatment, and what information do they have?
Ivermectin’s potential use as a COVID-19 therapeutic made headway last December during a Senate Homeland Security Committee meeting called Focus on Early Treatment of COVID-19. Dr. Pierre Kory, a pulmonary and critical care specialist, testified about the drug’s usage for treatment of the disease.
«Ivermectin is highly safe, widely available, and low cost,» Kory said in the Senate meeting. «We now have data from over 20 well-designed clinical studies, 10 of them randomized, controlled trials, with every study consistently reporting large magnitude and statistically significant benefits in decreasing transmission rates, shortening recovery times, decreasing hospitalizations, or large reductions in deaths. These data show that ivermectin is effectively a ‘miracle drug’ against COVID-19.»
During his testimony, Kory referred to a paper he authored — Review of the Emerging Evidence Demonstrating the Efficacy of Ivermectin in the Prophylaxis and Treatment of COVID-19 — that was published in the May edition of the American Journal of Therapeutics.
The paper was also included in the Frontiers of Pharmacology journal in January but was then removed in March. Dr. Frederick Fenter, chief executive editor of the journal, said the paper was removed due to «strong, unsupported claims based on studies with insufficient statistical significance, and at times, without the use of control groups.» Fender also said the authors promoted their own specific ivermectin-based treatment, which goes against editorial policies.
A study listed in Kory’s paper involved giving ivermectin to 234 uninfected health care workers in Argentina and found those who received the drug were far less likely to be diagnosed with COVID. For mildly ill patients, an Iraq study saw a quicker recovery time.
There are also studies that show otherwise. A clinical trial of 476 patients found ivermectin didn’t improve the recovery time in patients who had COVID-19. A review of 10 random clinical trials, with more than 1,000 participants, also didn’t find improvements with ivermectin. One Egyptian study claimed to show positive results, but it’s since been redacted over ethical concerns. Another study, of 1,500 patients, found that ivermectin had «no effect whatsoever.»
Merck, the company that discovered ivermectin, released a statement in February saying there was «no scientific basis for a potential therapeutic effect against COVID-19 from pre-clinical studies» and «no meaningful evidence for clinical activity or clinical efficacy in patients with COVID-19 disease.» It also cited a lack of safety data from major studies.
Why is there controversy over ivermectin?
The debate about ivermectin’s usage to treat COVID-19 has gone from the hospital to social media, exacerbating the discourse as well as the vitriol. While those in support of the drug appear to want an end to the pandemic, their arguments in favor of ivermectin have become fodder for anti-vaxxers and conspiracy theorists.
Groups that have spread misinformation about COVID-19 throughout the pandemic latched onto ivermectin’s usage following Kory’s Senate testimony. Anti-vax groups on Telegram share misinformation about the vaccine while asking where they can buy the drug. Rumble, an alternative video platform to YouTube, has pages of videos falsely saying vaccines are ineffective while advising people to also take ivermectin.
Anti-vax posts and videos can also be found on YouTube, Facebook and Twitter, although the companies are attempting to take these posts down or make them harder to find.
Kory was a guest on the Dark Horse Podcast hosted by Bret Weinstein, a former professor at Evergreen State College, on June 1 to talk about ivermectin. That video was eventually demonetized on YouTube and Weinstein’s channel received a strike, which prevented him from posting content for one week and could lead to its removal if he receives two more strikes within 90 days.
YouTube says its actions on Weinstein’s videos were part of its policies.
«While we welcome open discussions of potential treatments and clinical trials related to COVID-19 on YouTube, based on guidance from the CDC, FDA and other local health authorities, we don’t currently allow content that recommends ivermectin as an effective treatment or prevention method for the virus,» said Ivy Choi, a YouTube spokesperson. «We craft our policies to prevent the risk of egregious real-world harm, and update them as official guidance evolves. We do allow exceptions to our policy about ivermectin, including content that also gives viewers the full context of the FDA’s current position.»
Because of YouTube’s decision, the controversy over ivermectin grew and became tied to what some claim to be «big tech censorship.»
What is required for ivermectin to get approved for COVID-19 treatment?
For the public health agencies, it’s going to come down to the results of large clinical studies being conducted around the world.
«In the UK, it was announced that ivermectin will be added to the Principle Trial, a large clinical study designed to assess potential COVID therapies for non-hospitalized therapies for patients at higher risk for severe disease,» said Dr. David Shafran, head of pediatrics at telehealth app K Health. «This should demonstrate more definitively the efficacy of ivermectin in early-stage COVID infections. Fingers crossed because it’s a cheap medication with a good safety profile. It would be great to add this to the armament of medication to fight COVID.»
The Oxford University Principle Trial has more than 5,000 participants and will give a three-day course of oral ivermectin treatment to individuals randomly and compare their results to individuals who will receive standard care.
In the US, the NIH is evaluating therapeutics for COVID-19 with its Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) master protocol. ivermectin was added in phase three of ACTIV-6, which will test the effectiveness of repurposed drugs.
«The ACTIV prioritization group, trial team and trial oversight groups continuously track new data on any agent we are studying in our trials and evaluate that data for how it might influence our testing of that agent and the safety/well being of the participants in the trial,» said Dr. Sarah Dunsmore, a program director at the National Center for Advancing Translational Sciences that is part of the NIH.
What’s unclear is how long the whole process will take. The studies need time to be completed, and then the agencies will require additional time to come up with decisions based on the data.

Copilot Health Is Microsoft’s Doctor-Built Spin on Medical AI
Microsoft doesn’t want its AI to be your doctor. It wants to make you better prepared when you do see them.
Microsoft is taking a major swing at health AI. The company announced on Thursday that it’s introducing Copilot Health, a new experience inside its chatbot that will bring together all your medical records and wearable data with an AI that’s designed to help you understand it all.
«We are really on the cusp of building a true medical superintelligence,» said Mustafa Suleyman, Microsoft AI CEO. «One that can learn everything about you, all of your health conditions, from your wearable data, your electronic health records, and use that to provide support and insights and intelligence at your fingertips.»
A recent Microsoft survey found that mobile Copilot users ask the chatbot health-related queries more than for any other topic. Copilot Health was built to answer those questions. Microsoft’s health AI was fine-tuned by its in-house clinicians and an external panel of hundreds of clinicians in more than 24 countries. It uses the National Academy of Medicine’s framework for evaluating credible medical sources and information from Harvard Medical School via a 2025 licensing agreement.
Copilot Health is inside the regular, consumer version of Copilot. But it’s an entirely separate experience, designed that way to keep your health information separate from your usual chats. Because it’s been specifically trained for health questions, it ought to be more helpful and accurate than the regular version of Copilot or another chatbot. ChatGPT introduced a similar experience earlier this year.
Your health information won’t pop up in responses from the regular Copilot, only in the new health tab. You can delete your data at any time by simply toggling off a setting — something so easy it raises the question why all AI companies don’t make it that simple to delete your data.
Your information isn’t used to train Microsoft’s AI models, the company says. But your medical information in AI tools like Copilot is not protected under the Health Insurance Portability and Accountability Act (HIPAA).
The benefit of using Copilot Health is having a place where all your medical and health information lives, with an AI that’s trained to help answer your questions about it. You can connect data from your smartwatches and rings, as well as upload your medical records. Through a third-party program called HealthEx, you can upload files from multiple doctors’ offices, hospitals and labs at one time.
Copilot Health is not a doctor
If you choose to share your electronic health record, the AI can make more informed recommendations and reference specific doctors’ visit notes and lab results. But don’t use Copilot Health as a replacement for a physician. What the AI can do is discuss your health concerns, help you prepare for upcoming appointments and help you build healthier habits.
«Copilot Health is not meant to give you a definitive diagnosis or a formal treatment plan, but it’s certainly here to support you in getting to the right answers,» said Dr. Dominic King, vice president of health at Microsoft AI. The former surgeon led the team that built Copilot Health.
For example, it can help you come up with a list of questions to ask your doctor, break down lab results and find a provider that accepts your insurance. Copilot Health can discuss your health concerns, like understanding any new symptoms, but it can’t diagnose or prescribe medication.
Microsoft is doing a slow rollout, beginning with adults (ages 18 plus) in the US, with English as the only language. You can sign up to join the waitlist for Copilot Health now.
There are some existing uses of AI in health care today, but they’re disparate. Wearables have new AI-powered data insights and coaching. Some doctors are using AI scribe tools to take notes during appointments with patients. Administrative and insurance work also has its own AI tools, particularly around claims processing (including making denials, in some cases). The common thread is that none of the AI is without flaws, and it should never be used to make important decisions without human oversight.
For AI believers, the tangled, bureaucratic web of American health care is the perfect place to prove that AI intervention can make a real difference. But AI in health care is like putting a Band-Aid on a gunshot wound — a halfway measure that doesn’t fix the underlying problems.
It’s too soon to tell if Microsoft’s goal of a medical superintelligence is viable. But for now, Copilot Health illustrates a more productive use of AI — more than filling the internet with slop.
«I think it is perhaps the most important and most positively impactful contribution that AI can make in the world,» Suleyman said. «And it’s enormously important to us.»

The Fastest Way to Open Any App Is Hiding on the Back of Your iPhone
Your iPhone’s Back Tap feature can be customized to open any app.
Tapping the screen on an iPhone opens an app. What does tapping on the back of your phone do? A number of things, it turns out. It’s a super useful hack that you’ve likely been missing out on. In fact, it’s the fastest way to launch the camera or open specific apps without hunting through folders. In 2026, it’s the ultimate hack for making your hardware work harder for you without touching the display.
The feature is part of the Back Tap tool in your iPhone’s accessibility settings. Once enabled, it can trigger almost anything your phone can do, from turning on the flashlight to opening Shazam before a song ends. You can even set it to open the Control Center, take a screenshot or run a custom Shortcut with two or three quick taps. It’s fast, discreet and surprisingly powerful once you set it up.
The feature is called Back Tap and, like the Action Button on newer iPhones, it gives you one more way to use your device without touching the screen. You can activate it by tapping anywhere on the back of your phone, including on the camera module. The best part is that it works even if you have a fairly thick case on your iPhone.
Back Tap is available on iPhones as old as the iPhone 8, as long as they’re running iOS 14 or later. We’ll show you how to enable it and how to use it with your Shortcuts app for nearly endless possibilities.

What is the iPhone Back Tap feature?
Back Tap is an iPhone feature introduced in iOS 14. It lets you perform shortcuts on your iPhone by double- or triple-tapping on the back of the device.
You can customize Back Tap on your iPhone to easily perform common actions like pulling up the Control Center or Notification Center, especially useful if you have a larger phone and can’t swipe down from the top of the screen without some complex finger gymnastics. You can even have two separate functions enabled at the same time: Back Tap can distinguish between a Double Tap and a Triple Tap.
Depending on the number of times you touch the back of your iPhone, you can set Double Tap to open your Notification Center and Triple Tap to take a screenshot. Or, you can make Double Tap open the Control Center and Triple Tap launch the Magnifier app. Experiment with Back Tap to find the right combinations of taps and functions that best fit your needs.
And you aren’t limited to just the Back Tap options that are available by default. Thanks to the Shortcuts app, you can set up Back Tap to perform specific functions or launch any app. For example, you can create a simple shortcut that opens Shazam or starts a voice recording, then activate it with a quick Double Tap or Triple Tap. You can also use Back Tap to trigger a more elaborate shortcut, such as automatically sending photos and videos to specific photo albums.
How do I set up Back Tap on my iPhone?
To enable Back Tap, go to your Settings app. Then go to Accessibility → Touch → Back Tap. There, you’ll find a list of options for configuring Double Tap and Triple Tap.
Here is the full list of functions that you can map to a Double Tap or Triple Tap:
- None
- Accessibility Shortcut
System
- App Switcher
- Camera
- Control Center
- Flashlight
- Home
- Lock Rotation
- Lock Screen
- Mute
- Notification Center
- Reachability
- Screenshot
- Shake
- Spotlight
- Volume Down
- Volume Up
Accessibility
- AssistiveTouch
- Background Sounds
- Classic Invert
- Color Filters
- Control Nearby Devices
- Dim Flashing Lights
- Live Captions
- Live Speech
- Magnifier
- Smart Invert
- Speak Screen
- VoiceOver
- Zoom
- Zoom Controller
Scroll Gestures
- Scroll Down
- Scroll Up
At the bottom of the menu, you’ll also see a list of Shortcuts. These options will vary depending on what’s available in your Shortcuts app.
The one potential downside to Back Tap is that you don’t get any tactile feedback when you use it, so you might accidentally trigger it at the wrong time and not realize it until later. For instance, you might double-tap without meaning to and set off your flashlight by accident. In that case, you might want to remap your Double Tap to a less conspicuous function. Or, you can leave Double Tap off and only use Triple Tap, which you probably won’t trigger as often.
How do I use Back Tap to take a quick photo?
One way to set up Back Tap is to map Double Tap to the Camera and Triple Tap to Volume Up or Volume Down. Because you can press either of the volume buttons to instantly take a picture, you can get the same effect if your volume buttons are mapped to Back Tap. With this combination, you can capture a photo with five quick taps on the back of your iPhone (though you’ll have to pause briefly between performing the Double Tap and Triple Tap, so that your phone can distinguish between the two actions).
This Back Tap combination even works if your phone is locked. Again, spend some time trying out different combinations of taps and features to find which ones are most useful for you.

Social Media and AI Want Your Attention at All Times. This New Documentary Says That’s Bad
Your Attention Please, a documentary premiering this week at SXSW in Austin, Texas, explores how we live in the attention economy.
«Do you remember the world before cellphones?»
The question comes early in Your Attention Please, a documentary premiering this week at South by Southwest in Austin, Texas. And it hit me harder than I expected. As a 27-year-old tech reporter, I realized I don’t have too many clear memories of life before smartphones. My adolescence unfolded alongside the rise of smartphones, social media, push notifications and the routine of endless scrolling. Like many people my age, I’ve spent most of my life inside the attention economy — without ever really stepping outside it.
That’s the uneasy territory the documentary explores.
CNET was given exclusive early access to the film’s trailer, embedded below.
Exploring how tech shapes our behavior
Director Sara Robin said she originally set out to make something smaller: a documentary about people trying to reclaim their attention by breaking unhealthy phone habits. In an interview with CNET, Robin described the idea as a personal story about focus and self-control in an age of constant distraction.
As Robin interviewed researchers, technologists and families affected by social media and cyberbullying, the film’s scope widened. What started as a question about individual habits quickly became a larger investigation into how modern technology systems are designed to shape human behavior. The story stretches from the rise of social media to the emerging influence of AI.
Along the way, Robin and her collaborators kept hearing the same observation from different corners of the digital world: Social media didn’t just change how people communicate; it quietly rewired what we value. Experiences that were once private or emotional — friendship, affection, belonging — began to acquire numerical equivalents. Followers, likes, comments, views and shares began to be how we saw our own self-worth. In the architecture of social platforms, those numbers function as a kind of social currency.
Trisha Prabhu, a digital-safety advocate and inventor of the anti-cyberbullying technology ReThink, argues that social platforms did more than create new online spaces. She says they fundamentally reshaped how social validation works. The metrics that define popularity often reward attention-seeking behavior and amplify conflict, while genuine connection is now harder to quantify and, therefore, easier to overlook.
Prabhu warns that the same dynamics already driving problems like cyberbullying could accelerate as automated systems become more capable. AI tools can generate abusive messages at scale, produce convincing impersonations or create deepfakes that spread rapidly online. In some cases, the technology may even blur the line between human interaction and machine-generated communication, which could deepen loneliness or encourage harmful behavior.
«There’s AI exacerbating existing harms [like automating cyberbullying], but then I also think that there’s AI creating completely new harms,» Prabhu told CNET. «There are reports of AI tools encouraging users, including minor users, to commit self-harm… Even for the everyday user who’s not experiencing the extreme outcome, I think we have to ask ourselves how much of our time and connection we want spent with an AI tool as opposed to a fellow human being.»
Bringing attention to attention
What struck Robin during filming the documentary was how universal these anxieties felt. Across conversations with families, educators and advocates around the world, the themes were remarkably consistent: overstimulated attention, declining focus in classrooms, rising anxiety among young people and a persistent sense of dread that comes from always being plugged in.
Those shared concerns have helped spark a coordinated moment around the film’s release.
On March 11, more than 25 organizations focused on digital well-being will simultaneously release the trailer for Your Attention Please as part of an initiative called Stand for Their Attention. What began as a small collaboration among five groups quickly grew as word spread through advocacy networks. The coalition now includes organizations such as Common Sense Media, Protect Young Eyes, Mothers Against Media Addiction, the Center for Humane Technology, Smartphone Free Childhood and Scrolling to Death.
The idea behind the synchronized launch is simple: Use the attention surrounding the documentary to highlight the growing movement that’s already working to reshape digital culture.
Many people feel overwhelmed by the scale of the problem, Robin says, but behind the scenes, a widening ecosystem of advocates is experimenting with ways to build healthier digital environments, from redesigning products to changing norms around screen use.
The campaign also arrives at a moment of growing scrutiny around the attention economy. Lawmakers in the US and abroad are increasingly debating how social platforms affect youth mental health and childhood development. Boycotts around AI use are taking off. Researchers are studying how these algorithms and chatbots influence behavior. Individuals are trying to figure out how much technology belongs in everyday life.
What can we do about it?
Despite the weight of those conversations, Robin says the goal of the film isn’t to leave audiences feeling powerless. In fact, the rapid rise of public awareness around AI has made her more optimistic than she was during the early days of social media. The systems shaping digital life, she argues, are built by people, which means they can also be rebuilt.
«We have more power than we think,» Robin said. «And there are a lot of different ways to get involved in this, from changing individual habits to changing the culture in your own family and in your community, designing technology differently, getting engaged in these conversations, all the way to pushing for legislative change.»
The film intentionally avoids presenting a single solution.
Instead, Your Attention Please asks a broader question: What happens when attention, one of the most human parts of our lives, becomes one of the most valuable commodities in the global economy? And perhaps more importantly, what kind of digital world do we want to build next?
