EXCLUSIVE Benadryl linked to crippling DISEASE: Doctors issue warning to age group at highest risk
Millions of Americans take Benadryl every year to relieve allergies, but doctors have uncovered a shocking link between the medication and a devastating disease. Benadryl's active drug diphenhydramine blocks receptors for histamine, an inflammatory chemical released by the immune system that can trigger symptoms like a runny nose and itchy skin.

Safety alert for over-the-counter remedy taken by millions - after pills trigger disease that fuels bowel cancer in healthy 18 year-old
Frequently taking a common type of painkiller could trigger inflammatory bowel disease (IBD)—raising the risk of bowel cancer—experts warn. Medics raised the alarm after treating an 18-year-old boy who developed colitis—a type of IBD—after taking over-the-counter allergy and pain relief medication continuously for almost three years. IBD is a known risk factor for bowel cancer and experts have long warned that those who have had the condition for years are at increased risk of developing the disease. The unnamed American teen sought medical help for bleeding from his rectum and extreme fatigue—according to doctors who shared his tale in a medical journal. He told medics he had been taking diphenhydramine, an over-the-counter hay fever medication and a non-steroidal anti-inflammatory drug (NSAID), daily to combat debilitating headaches and allergies for almost three years. NSAIDs are a class of painkiller—famous examples being ibuprofen, aspirin, and naproxen—which are commonly used to alleviate pain and swelling. Pills combining diphenhydramine and NSAID are available in both the US the UK under brands like Advil PM and Motrin PM, as pain relief and sleep aids. While not naming the brand of medication the teenager took, doctors said he had taken the equivalent of 600mg of NSAIDs twice a day. Brands that make diphenhydramine and NSAID combination pills warn patients not to take more than two tablets in 24 hours, equivalent to around 400mg of NSAID. Medics then performed a colonoscopy—where a thin flexible camera is inserted into the rectum—and found the tissue inside was severely inflamed. Writing in the journal Cureus, medics said he was then diagnosed with colitis, a form of IBD which specifically develops in the colon. They theorised that his frequent use of NSAID drugs had disrupted the production of mucus that protects the digestive system, causing irritation. Irritation of the digestive system is a known risk of these drugs and as result they can lead to bleeding, ulcers and potentially colitis. Some studies have linked using NSAID drugs with an 86 per cent increased chance of developing colitis. The medics who reported the case said these increased risks are why doctors often prescribe a separate medication to patients' who have to take NSAIDs frequently for chronic pain issues, in order to protect their guts from this potential damage. However, they noted that their patient was an extreme example and occasionally using a medication like ibuprofen will not carry the same risk. But they added that the risk is something to be aware of given how readily patients are able to take these over-the-counter medications without medical supervision. 'Given the widespread availability of these medications and their over-the-counter accessibility, it is imperative that patients suffering from chronic inflammation or long-term pain be advised to avoid NSAIDs, or to use them only under the direct guidance of a supervising clinician,' they said. WHAT IS INFLAMMATORY BOWEL DISEASE? Inflammatory bowel disease (IBD) is a medical term that describes a group of conditions in which the intestines become inflamed (red and swollen). Two major types of IBD are Crohn's disease and ulcerative colitis. Ulcerative colitis affects the large intestine (colon) whereas Crohn's disease can occur in any part of the intestines. Symptoms may include: Abdominal cramps and pain frequent Watery diarrhoea (may be bloody) Severe urgency to have a bowel movement Fever during active stages of disease Loss of appetite and weight loss Tiredness and fatigue anaemia (due to blood loss) People of any age can get IBD, but it's usually diagnosed between the ages of 15 and 40. The conditions are chronic and cannot be cured so treatment usually relies on medication and lifestyle changes to manage the symptoms, but may include surgery. IBD is thought to affect some three million people in the US, over 300,000 Britons, and 85,000 Australians. Source: Crohn's & Colitis Australia In the teen's case, once he was stable, he was prescribed anti-IBD drugs and told to stop using NSAIDs. However, despite being scheduled for a follow-up colonoscopy, he never attended, so medics were unable to determine how successful this had been. For years scientists have been unsure exactly what causes IBD to develop in some patients but not others. Earlier this year, however, researchers in London discovered a genetic weakness present in 95 per cent of people with IBD. An estimated half a million Britons and some 3million Americans are thought to have IBD, with the condition affecting more than 10million globally. IBD arises when the immune system mistakenly attacks the bowel, causing an array of debilitating symptoms including abdominal pain, diarrhoea and blood in stools. The disease can also cause sudden weight loss and crippling fatigue. While no cure is available, symptoms can be managed with drugs. These tend to be most effective when given soon after diagnosis. Estimates vary on exactly how much having IBD increases the risk of bowel cancer, with some charities citing studies which found it raises it by 7 per cent compared to the general population. But charities are keen to highlight that the vast majority of patients with IBD won't develop the disease. They do, however, advise people with IDB to keep in mind other risk factors for the cancer, such as smoking, drinking alcohol and being overweight that could further increase their individual risk. It comes as experts have repeatedly warned of a concerning and mysterious rise in rates of bowel cancer among under 50s. A recent global study found rates of bowel cancer in under 50 year-olds are rising in 27 of 50 nations. England is averaging a 3.6 per cent rise in younger adults every year-one of the highest increases recorded. While the disease is known to be linked to obesity, experts have noted that the disease also seems to also be occurring in fit and healthy patients. Some believe the explanation must lie in environmental factors young people have been exposed to more than previous generations. Signs of bowel cancer include abdominal pain, a lump in the abdomen, bloating and feeling very tired or short of breath. Bleeding from the back passage, or blood in the stool, occurs when cancerous tumours bleed into the digestive tract. However, bowel cancer can also appear with no symptoms until it has spread, where it becomes harder to treat. Overall, just over half of bowel cancer patients are expected to be alive 10 years after their diagnosis.

Quebec man's death prompts coroner's call to tighten controls on diphenhydramine sales
A Quebec coroner is recommending that diphenhydramine — an antihistamine and sedative sometimes used to sleep better — should be better managed in pharmacies after the overdose death of an 18-year-old man south of Montreal in December 2023. The young man, whose identity is not revealed in the report made public, died of acute diphenhydramine poisoning at his home in St-Mathias-sur-Richelieu. On the morning of Dec. 11, 2023, the man was found by his mother in his bed, unconscious and laying on his back. Toxicological analysis found the man had a lethal level of diphenhydramine in his blood. The drug is the sedating ingredient in some over-the-counter antihistamines including the brand Benadryl, among others. The coroner found the circumstances surrounding the death raise questions about the uncontrolled availability of a potentially lethal over-the-counter substance. He noted there is consensus about the risks of poisoning among scientific bodies, but it's not stored behind the counter. "I cannot understand why the sale of diphenhydramine ... is not better controlled," coroner Vincent Denault wrote. "I can't understand why diphenhydramine is available over the counter, especially since Gravol, which also contains diphenhydramine, isn't available." In a report dated from late April but released this week, the coroner wrote the man's death is attributed to the acute toxicity of diphenhydramine, a central nervous system depressant which if consumed in sufficient quantities causes fatal respiratory depression and irregular heartbeat, which can lead to fatal cardiac arrhythmias. The coroner noted there were previously used empty jars and blister packs of diphenhydramine tablets in the man's bedroom. "Was he taking them to sleep better? Could he have taken pills in the same way, but in larger quantities, during the night of December 10-11, 2023?" the coroner asked. Denault noted it wasn't the first time deaths have occurred due to the drug. The coroner has already weighed in on three previous Quebec investigations. There was an uptick around 2020 after the so-called Benadryl TikTok challenge on social media invited users to consume large quantities of medication tablets containing diphenhydramine. "The deaths of children have put a face to this dangerous trend," Denault wrote. "The scientific literature confirms that diphenhydramine is consumed in high doses for its euphoric and hallucinogenic effects, and that people have used it to commit suicide." Denault's recommendation was for the provincial office of professions to take steps to amend regulations involving the sale of medicinal products, to classify diphenhydramine intended for oral administration in a section that requires more management by pharmacists. That management would include creating a file, noting the sale and carrying out a pharmacological study of the file. Denault also asked the coroner's office to share the report with the Collège des médecins du Québec — the province's College of Physicians — and the Ordre des pharmaciens du Québec, the body that oversees pharmacists in the province. Jean-François Desgagné, president of the pharmacists' order, said this week the order would review the coroner's recommendation to reclassify the drug to assess the appropriateness of moving it behind the pharmacist's counter.
