Doctors issue warning over viral McDonald's hack claimed to 'cure' migraines
The so-called 'McMigraine Meal' went mainstream in May when US neurologist Dr Jessica Lowe described it as a 'miraculous' fix in a video that has since racked up almost 10million views
In the clip, first reported by MailOnline, Dr Lowe—who suffers from chronic migraines herself—told followers: 'The order is a large Coke and a large fries. And this somehow miraculously makes your migraine go away.'
Coke contains caffeine—roughly 10mg per 100ml—which works by constricting blood vessels and blocking pain signals in the brain, and reducing inflammation.
Fries, meanwhile, deliver filling carbohydrates, adds Dr Lowe: 'A lot of people have migraines that are provoked by hunger—those carbs are certainly gonna help out in that department.'
Since then, social media has been flooded with similar posts from migraine sufferers swearing by the fast-food fix.
One TikTok user wrote simply: 'It works,' after trying the combo following a 48-hour headache.
But while the trend continues to gain traction, doctors have urged caution—warning that the hack may offer only short-term relief and could actually trigger migraines in some people.
Speaking to HuffPost UK, Dr Rupa Parmar, GP and Medical Director at Midland Health, said: 'A reason why the McDonald's trick seems to work is that a large Coke at McDonald's contains... caffeine, which has long been used to lessen migraine symptoms.'
She added: 'The stimulant helps to reduce inflammation, decreases the pressure on the brain, increases the benefits of pain relief like ibuprofen, and can provide a brief respite from migraines for those who don't consume it regularly.'
However she warned that, while the hack may stop the early stages of migraine pain, it may not be worth it in the long run.
'Caffeine is a very common headache trigger,' she warned, adding that those who consume large amounts regularly can suffer worse headaches.
She concluded: 'Opting for fast food as a quick fix to solve your migraine problems is also unlikely to produce any long-lasting benefits.'
Migraine is a complex neurological condition that causes intense, often throbbing head pain—usually on one side.
Other symptoms include nausea, sensitivity to light, and visual disturbances.
Unlike a common headache, an attack can last for hours or even days and often leaves sufferers unable to function.
The exact cause isn't fully understood, but it's thought to involve abnormal brain activity affecting nerve signals, chemicals, and blood vessels.
Triggers can include stress, hormonal changes, lack of sleep, certain foods, dehydration, and even weather changes.
Migraines affect around 10 million people in the UK, and an estimated 39 million in the US. Women are up to three times more likely to suffer than men.
Several chronic migraine sufferers told the BBC they had tried the cola-and-fries remedy—with mild success.
Nick Cook, from Oxfordshire, said he carries 'a wallet full of drugs' and is willing to 'try anything' to manage the condition.
'When you live with the condition, and you're working a five-day week and you need to carry on, you'll give anything a go,' he told the BBC.
He said Coke can occasionally help—but only if he acts fast.
'If I catch it soon enough it can sometimes work, when my vision goes fuzzy and I can feel one coming on.'
He said it doesn't replace his prescription amitriptyline, but helps him 'last until the end of the day'.
Kayleigh Webster, 27, who has had migraines since childhood, believes it's the salt on the fries that seems to offer the biggest benefit.
'It can help,' she told the BBC. 'But it's certainly not a cure.'
The only treatment that's brought her lasting relief is medical Botox—a course of injections to her head, face and neck to block pain signals at the nerve endings.
Dr Kay Kennis, a GP specialising in migraine and a trustee of The Migraine Trust, said there's some logic behind the McDonald's fix—but also warned against regular use.
She said: 'There are some painkillers that people take for migraines that have caffeine—and some do respond well to that—but we don't fully know why.
'[But] too much caffeine can be a trigger too—and you can end up in a worse situation in the long run.'
Processed food is more concerning, she added, since it can contain tyramine—a compound known to trigger attacks.
Professor Peter Goadsby, a neurologist at the NIHR-King's Clinical Research Facility, said research into new treatments like gepants—drugs which block pain receptors before a full-blown attack develops—is offering hope after years of limited innovation.
Prof Goadsby warned against relying on TikTok trends: 'You want to have regularity, avoid the highs and lows.
'If you can feel the warning signs [of an attack]—yawning, sleepiness, mood change, passing more urine and even craving salt and sugar—listen to your body.'
Experts agree that the timing of migraine medication is crucial—and taking it at the first sign of symptoms is far more effective than waiting for the headache to take hold.
This is especially true for triptans, a class of drugs commonly prescribed to treat migraine attacks.
These medications work by narrowing swollen blood vessels in the brain and blocking pain signals—but only if taken early enough.
Research shows that taking triptans or pain relief within the first hour of symptoms—often during the 'aura' phase or at the first twinge of head pain—can reduce both the intensity and duration of the attack, and in many cases prevent it from escalating entirely.
Waiting too long can not only reduce the chances of full relief but also increase the likelihood of needing repeat doses or stronger medication later on.

US allows emergency authorizations of animal drugs to fight screwworms
CHICAGO, Aug 19 (Reuters) - U.S. health officials gave the Food and Drug Administration the power to quickly authorize veterinarians and farmers to treat or prevent infestations of a flesh-eating livestock pest with animal drugs that may be approved for other purposes or available in other countries, the Department of Health and Human Services said on Tuesday. No cases of the New World screwworm have been confirmed in the U.S. for decades. However, the Trump administration and livestock ranchers anticipate infestations that could reduce the nation's cattle herd and lift beef prices, already at record highs. Screwworm, a parasitic fly that eats livestock and wildlife alive, can infest any warm-blooded animal. Last month, the pest was found in Mexico about 370 miles from the U.S. border, prompting the U.S. Department of Agriculture to indefinitely halt imports of Mexican cattle. The best method to fight screwworm is by breeding sterile flies that reduce the mating population of wild flies. However, experts say many more sterile flies would be needed beyond the current production capacity to slow screwworm's spread in Latin America. It can take a year or more to build facilities to increase sterile fly output. Cattle ranchers may need quick access to screwworm drugs in the meantime, and there are no FDA-approved drugs for screwworm in the U.S. The Department of Health and Human Services said it allowed the FDA to issue Emergency Use Authorizations that permit the use of animal drugs not formally approved to treat or prevent screwworm. The FDA did not immediately respond to a question about whether drugmakers have already sought emergency authorizations. "The risk to human health in the United States remains very low, but the potential future threat to animal populations and the food supply chain requires proactive action," the FDA said. When HHS declares that an emergency use authorization is appropriate, the FDA can allow unapproved medical products or unapproved uses of medical products to tackle serious or life-threatening diseases, if no alternatives are available. In 2020, HHS allowed the emergency use of drugs during the COVID-19 pandemic. If screwworm is found in U.S. animals soon, an important part of the response would involve using drugs in ways that are not in line with their label directions, Tristan Colonius, chief veterinary officer for the FDA's Center for Veterinary Medicine, said during a webinar last week. This could allow veterinarians and ranchers to access products more quickly, rather than waiting for a longer FDA review process. Colonius said the FDA was assessing literature reviews of products that were approved for other uses to determine what may be effective against screwworm. The agency also wants products with specific approvals for screwworm, he added. The FDA has been looking at foreign markets where screwworm has been endemic to see whether drug companies will bring products to the U.S., Colonius said. In May, cattle producers' group R-CALF USA asked the FDA to allow ranchers to feed ivermectin, opens new tab to livestock, as a precaution against the potential return of screwworm. The USDA has successfully used the anti-parasite drug to control the northern movement of cattle fever ticks, another pest that can be fatal to livestock, according to R-CALF. The USDA said on Friday it would spend up to $750 million to build a facility in Texas that produces sterile flies. Agriculture Secretary Brooke Rollins did not say when the plant would open but previously said such a facility would take two to three years to build.

US pediatric organization diverges from CDC in Covid-19 vaccine advisory for children
The American Academy of Pediatrics (AAP) is urging that children as young as six months and up to 23 months old receive the Covid-19 vaccine – a position that diverges from the current federal guidance given by the Trump administration's health agencies. The AAP released its updated childhood immunization schedule, which outlines recommendations for vaccines against Covid-19, influenza and RSV for individuals under 18. 'It differs from recent recommendations of the advisory committee on immunization practices of the CDC, which was overhauled this year and replaced with individuals who have a history of spreading vaccine misinformation,' the organization said in a statement. The announcement follows a decision from health and human services secretary Robert F Kennedy Jr in late May to halt CDC recommendations for healthy children to receive the Covid-19 vaccine. Previously, the CDC advised vaccination for everyone six months and older with the latest available dose. The CDC currently advises that Covid-19 vaccinations for children aged six months through 17 years should be determined through 'shared clinical decision-making'. The AAP recommends vaccination for anyone under 18 who is at higher risk of serious illness from Covid-19, resides in a longterm care or congregate living facility, has not previously been vaccinated, or shares a household with someone at elevated risk. 'The academy has been making pediatric immunization recommendations since the 1930s, that has not changed,' Dr Susan Kressly, president of the AAP, told ABC News. 'But what has changed is that this year, we're doing it in the environment of misinformation, which makes it more important than ever that we provide clear and confident guidance, because the majority of American families really depend on us for this guidance.' AAP says infants and toddlers between six and 23 months face the greatest risk for severe outcomes from Covid-19 and vaccination offers protection against serious illness. Even as medical groups continue to disagree with federal agencies, insurers often base coverage on guidelines from the CDC's advisory committee on immunization practices (ACIP). If ACIP declines to endorse a vaccine, families may have to pay out of pocket, and the shot may not be provided through the federally funded Vaccines for Children program. Kennedy's restructured vaccine panel has maintained support for annual flu shots but voted to limit them to single-dose formulations without the preservative thimerosal. The AAP, however, maintains that the preservative poses no risk and said physicians should administer any approved flu vaccine suitable for the patient.

FDA issues urgent warning about possibly radioactive shrimp
Health regulators are urgently warning Americans to check their freezers after a radioactive substance was found in a popular bag of shrimp sold at Walmart. The FDA has told the public to avoid Great Value raw frozen shrimp due to contamination with Cesium-137, a radioactive isotope. Customs and Border Protection agents, who detected the radioactive isotope Cesium-137, or Cs-137, in shipping containers at four major US ports, sounded the alarm to the FDA. The FDA tested the contents of the shipping containers and confirmed on Tuesday that the shrimp, which came from a company in Indonesia called BMS Foods, was contaminated. CBP and the FDA are now working with Indonesian seafood regulators to pinpoint the precise source of the contamination. According to the agency, evidence suggests the shrimp was processed or stored in unsanitary conditions that likely led to the radioactive contamination, making it unsafe for people to eat. The risk of contamination from passing a contaminated shipping container is low, but that risk compounds if a person were to eat radioactive shrimp. Once inside your body, Cs-137 acts as a long-term, internal source of radiation that significantly increases cancer risk. The Do Not Eat warning is issued out of an abundance of caution, the FDA said, adding that testing to date has not confirmed the presence of contamination in any product currently being sold in stores. The contaminated shipping containers entered the ports of Los Angeles, Houston, Savannah, and Miami. The containers included three lots of Great Value brand frozen raw shrimp, all with best by dates of March 15, 2027. The FDA confirmed Cs-137 in one batch of breaded shrimp, but all contaminated shipments were prevented from entering the US. 'If you have recently purchased raw frozen shrimp from Walmart that matches this description, throw it away,' the FDA said. The FDA also instructed distributors and retailers to throw the product away. Anyone who believes they may have eaten it should consult their doctor. The agency added that it 'will continue working with industry to trace all implicated products processed by PT. Bahari Makmur Sejati through the supply chain to gather as much information about them as possible and take action as appropriate.' Low-level exposure to Cs-137 is common for everyone due to its persistent presence in the environment from past nuclear weapons testing in the 1950s and 60s, according to the CDC . The significant health risk, however, comes from highly concentrated sources found in medical and industrial equipment, where the material is sealed within protective shielding to prevent exposure. A serious danger emerges if this shielding is compromised, either accidentally or intentionally, allowing the release of the highly concentrated radioactive material. Significant external exposure to Cs-137 can result in severe health effects, including radiation burns, acute radiation sickness, and death. The high-energy gamma radiation it emits also elevates long-term cancer risk. If Cs-137 is ingested or inhaled, it disperses throughout the body's soft tissues, concentrating in the muscles, creating a persistent internal source of radiation.
