More than two years after allergy experts recommended newer antihistamines and warned against using Benadryl as a first-line treatment, many Canadians are still reaching for that recognizable brand name over others.
In October 2019, the Canadian Society of Allergy and Clinical Immunology (CSASI) put out a position statement regarding oral allergy medication, stating that newer antihistamines were safer than first-generation ones, and that they should be recommended over older staples like Benadryl due to a higher rate of potential side effects. The position statement referred specifically to medications that treat non-life-threatening allergic reactions such as hay fever and hives.
If it’s news to you that Benadryl is no longer recommended as a first-line treatment for common allergies, you’re not the only one. In 2022, it’s not only adult patients and parents who are still influenced by brand familiarity and haven’t made the switch — some doctors are as well, experts say.
“I think there are a fair number of pediatricians who still recommend Benadryl for allergies,” Daniel Flanders, owner and executive director of Kindercare Pediatrics in Toronto, Ontario, told CTVNews.ca in a phone interview.
“And if you speak to an allergist, they would simply say that that’s outdated advice.”
Benadryl is one of the most well-known brands for allergy medication, with numerous products available to buy without a prescription, including versions specifically made for children. Benadryl is approved by Health Canada, which has deemed it safe for over-the-counter use, concluding in a recent safety review of first-generation antihistamines that there hasn’t been any change in risk that would prompt it to change the drug to prescription-only.
While both first and second-generation antihistamines bind to receptors in the brain and spinal cord to block the release of histamines — the chemicals that cause allergy symptoms — first-generation crosses the blood-brain barrier and causes more sedation in patients, something that was corrected in second-generation antihistamines.
Because of this difference, first-generation antihistamines like Benadryl are associated with more side effects such as increased drowsiness, issues with motor functions and working memory, as well as a risk of hallucination or even death in the event of an overdose.
But if many experts have believed for years that Benadryl shouldn’t be the first choice for oral allergy medication anymore, why are many Canadians and doctors unaware of this?
“Unfortunately far too often, physicians and other health-care practitioners, including pharmacists and paramedics, continue to commonly recommend Benadryl as a first line antihistamine for treatment of allergic symptoms, including symptoms from food allergy,” CSACI told CTVNews.ca in an email, adding that its 2019 messaging has “still not reached many health-care practitioners.”
Flanders said that while he’s not aware of any doctors in his clinic still recommending Benadryl, there are likely many across Canada still turning to the well-known allergy medication to treat mild allergies.
“I would say probably for 10 years it has been the case that we’ve known that it’s better to use the second and third generation antihistamines preferentially over Benadryl, but […] one of the funny things about medicine is that it does take a long time for information to trickle down from research through to practice,” he said.
“It is measured in years. It’s not uncommon, but it takes a good 10 years for the standard of care for the practice to adjust to some of the changes that science discovers.”
Flanders said if he had to make an estimate, anywhere from 25 to 50 per cent of pediatricians may still be recommending Benadryl as a first line treatment, though he cautioned that this is just his personal assessment.
“I’m hopeful that more than half of my colleagues are making that correct recommendation [instead of Benadryl],” he said.
A big reason that Benadryl is still recommended by health-care professionals is the familiarity of that brand name, which has been a giant in allergy medication for decades.
“Benadryl has so much recognition as an allergy remedy,” Flanders said. “The trade name is so well known, and so commonly used that I could imagine it would take a whole lot of work to sort of deprogram and reprogram parents’ minds. And also the minds of doctors who are not sort of keeping up with the cutting edge [of medicine].”
It was a sentiment that CSACI echoed.
“The familiarity of health-care practitioners, parents and adult patients with Benadryl and other first generation antihistamines makes it difficult to motivate changes in practice,” the organization said.
WHY DID CSACI DECIDE BENADRYL SHOULDN’T BE RECOMMENDED?
More than two years ago, CSACI put out a paper explaining that newer antihistamines are just as effective and safer than first-generation antihistamines such as Benadryl, and that they should always be recommended over older antihistamines.
The active ingredient in Benadryl sold in Canada is diphenhydramine, and it’s one of the oldest first-generation antihistamines, having been available for sale since 1946.
In the position statement, CSASI explained that older antihistamines are associated with more severe side effects than second and third generation antihistamines which became available in Canada starting in the 1980s and had to pass high-quality trials.
“It is always preferred to use safer and more effective medications,” CSACI told CTVNews.ca in an email. “First generation antihistamines are significantly more likely to cause side effects, including sedation, poor sleep quality, and poor cognitive performance (including poor school and work performance). In addition, overdoses of first generation antihistamines can cause severe toxicity.”
Johnson & Johnson, the company that sells Benadryl in Canada, did not respond to a request for comment from CTVNews.ca.
In 2019, the company told the Canadian Press that “Benadryl products have been trusted by doctors and moms for more than 60 years to provide effective symptom relief from allergies and allergic reactions,” and that the products are approved by Health Canada and “when used as directed, are safe and effective.”
CSACI’s position statement explained that newer antihistamines have less serious side effects associated with them, and that as of 2019, accidental exposure to higher levels of second and third generation antihistamines had not resulted in severe adverse events, unlike first generation antihistamines.
In 2020, a TikTok “challenge” spurred some teenagers to take enough Benadryl to induce hallucinations, which resulted in several teens being rushed to hospital.
The CSACI statement mentioned that in Canada, online surveys had shown that Benadryl was, at the time, the “most recommended antihistamine for allergic symptoms in children in each of the last 7 years.”
WHY IS BENADRYL STILL AVAILABLE OVER THE COUNTER?
It’s important to note that Benadryl isn’t considered dangerous — when instructions are followed, serious side effects are rare.
CSACI’s position was that there are new options that are just as effective and have fewer side effects overall, or milder side effects.
“I wouldn’t so much say that one should never use [Benadryl], it just doesn’t make sense to use it currently or in present day, because there are alternatives that are just as good and have a better side effect profile,” Flanders explained.
“Why would you take a medication that you know has significant side effects when you can take another medication that does the exact same thing, but without the side effects?”
After CSACI released this position statement in 2019, there was a flurry of articles that questioned whether Benadryl should be available as over-the-counter medication. As a result, Health Canada announced that while products containing diphenhydramine met the requirements of the Food and Drugs Act, they would be assessing “to determine if further risk mitigation measures for diphenhydramine-containing products are required,” noting that the safety of children was a big concern of the Canadian public.
On March 1 of this year, Health Canada posted a summary of that safety review, which focused on whether there have been any increases in frequency of the known side effects associated with oral, over-the-counter diphenhydramine in children under two years old or an increase in frequency of overdoses in children under 18.
“There are no new safety concerns to warrant regulatory action at this time,” Health Canada stated in the monthly Health Product InfoWatch.
Flanders believes that one of the factors driving Benadryl’s enduring ubiquity in the minds of Canadians is because it’s available so easily.
“I think it would make sense to take Benadryl off the list of over-the-counter allergy medications, because just there are better options and there are side effects and those can have long term implications,” he said.
“And that might be a nice way to sort of educate or to leave the general public with no choice but to choose a more appropriate medication.”
In 2019, some pharmacists pointed out that putting Benadryl behind the counter doesn’t solve the safety issues, and could cause conflict if customers are still pushing for it.
Nardine Nakhla, a pharmacist who teaches at the University of Waterloo in Ontario, said at the time that there are many other products that contain diphenhydramine that are on the shelves, making it unrealistic to pull all of them, and that there are other products available over the counter that have safety concerns, making this a complicated problem.
IF I HAVE BENADRYL AT HOME, SHOULD I KEEP USING IT FOR MYSELF OR MY KIDS?
For CSACI, it’s pretty straightforward.
“It is strongly encouraged that parents replace older first generation antihistamines such as Benadryl in their medicine cabinets with newer generation antihistamines,” it stated.
Flanders said that his advice depends on a family’s budget.
“If the purchase was made and there isn’t much money in the budget and there’s really bad allergy symptoms that need to be controlled, then Benadryl will do the trick, so I think it’s reasonable to complete the package,” he said. “And then next time you need it, buy the newer generation antihistamine.”
But if the cost of replacing the Benadryl immediately isn’t a concern, “then I would go right ahead and buy the new one and throw out the Benadryl, because there’s better options,” he said.
CSACI’s position statement pertained to all ages, but Flanders said that as a pediatrician, he is more concerned about making sure that children are receiving the best medication for whatever ails them.
“I think there’s an added dimension of risk for children because they’re still developing and they’re still in a very formative period of their lives. So if a child is chronically sleep deprived, I think there are more dire long term consequences,” he said, referring to side effects for Benadryl pertaining to poor sleep.
“For kids who are going to be taking it on a regular basis, it does interfere with the quality of their sleep and it can interfere with learning and with their sort of day to day functioning. It’s not like it’s the end of the world if you take Benadryl periodically for allergy relief, it’s just, there’s better options.”
WHICH NEWER ANTIHISTAMINES ARE PREFERRED?
CSACI gave CTVNews.ca a list of newer antihistamines currently available in Canada that it recommends over first-generation antihistamines:
bilastine (Blexten)
cetirizine (Reactine)
desloratadine (Aerius)
fexofenadine (Allegra)
loratadine (Claritin)
rupatadine (Rupall)
“Many of these are available over-the-counter, some of which are also available as generic preparations, and others are only available by prescription,” CSACI stated.
New Brunswick‘s Liberal and Green parties are set to make announcements about health care on the campaign trail today as the provincial election race enters its second half.
Liberal leader Susan Holt is scheduled to hold her announcement this morning in Saint John, N.B., followed by lunch at the city’s market.
A spokesperson with the Progressive Conservative party shared few details about the event scheduled for leader Blaine Higgs in Fredericton this morning.
Green Party Leader David Coon will hold a news conference this morning about “local health-care decision-making” alongside deputy leader Megan Mitton in her Sackville, N.B. riding.
On Saturday, Coon said he was proud to put forward a gender-balanced slate among the party’s 46 candidates.
While the Liberals and Progressive Conservatives are running with full slates, the Greens are three candidates short and will not have full representation when the province’s residents go to the polls on Oct. 21.

EDMONTON – The Health Quality Council of Alberta is investigating how some medical referrals weren’t properly processed, potentially affecting 14,000 patients over the last five years across the province.
The referrals were made to specialists outside of Alberta Health Services, such as physiotherapists and dietitians.
The health authority’s CEO, Athana Mentzelopoulos, says it does an average 100,000 referrals per year, but in some cases it can’t confirm if patients received referral services.
She says the problem was flagged in late September, and a preliminary estimate suggests 31 patients may have experienced a potential negative outcome due to the delays.
The provincial government requested the investigation, and the quality council is to find out how the snag occurred and how it can be prevented in the future.
The health authority says it has begun notifying patients who may have been affected by the disruption, and the cases could date back to 2019.

WASHINGTON (AP) — If you have stained or chipped teeth, you might be considering veneers, customized teeth coverings that can restore a photogenic smile without more extensive dental work.
But dentists warn that these pricey cosmetic enhancements are at the center of a worrisome online trend: unlicensed practitioners without proper training or supervision offering low-cost veneers.
These self-described “veneer techs” often promote themselves on Instagram and TikTok, promising a full set of veneers for less than half of what dentists typically charge. Some also market their own training courses and certifications for people looking to get into the business.
It’s misleading, health professionals warn — and illegal. All states require dental work, including veneers, to be performed under the supervision of a licensed dentist.
On Thursday, Georgia law enforcement officials arrested Brandon Diller, who promoted himself to 158,000 Instagram followers as “Atlanta’s top veneer specialist and trainer.” Diller practiced dentistry without a license and sold “training and certificates, which were worthless” and “provided no legitimate or legal credentials,” according to an arrest warrant from Fulton County’s District Attorney’s office.
Here’s what to know about veneers and how to avoid bogus providers and services:
What are dental veneers?
Veneers are thin, custom-made dental coverings used to hide minor imperfections or to fill in gaps between teeth. Unlike crowns or more invasive dental implants, veneers are almost always considered cosmetic dentistry and generally aren’t covered by insurance.
Dentists usually charge between $1,000 and $2,000 per tooth for veneers, with higher prices for those made from porcelain compared with lower-grade materials.
Placing veneers involves stripping some of the natural enamel from the tooth and bonding the new covering into place. Because of that process, getting veneers is considered an irreversible procedure, according to the American Dental Association. They are not permanent, and can be expected to last between 5 to 15 years before they degrade and need to be replaced.
In recent months the ADA has been stepping up warnings about the risks of veneer procedures done by unlicensed individuals.
“Quality control is lost without the involvement of a licensed dentist,” said Dr. Ada Cooper, a New York-based dentist and ADA spokesperson. “We undergo years of education and training and need to be licensed by various regulatory bodies before we can practice.”
What are the risks of getting veneers from someone who isn’t licensed?
Improper veneer procedures can cause a range of health problems, including severe pain, nerve damage and tooth loss.
Patients need to be anesthetized before the enamel is removed from their teeth.
“It could be incredibly painful if they’re not anesthetized correctly,” said Dr. Zach Truman, who runs an orthodontics practice in Las Vegas. “You can also go too deep into the tooth and penetrate what’s called the pulp chamber, which contains blood vessels and nerves.”
One of the biggest problems Truman sees with unregulated veneer work is that customers aren’t getting screened for existing dental problems, such as gum disease and cavities.
“If you put a veneer on a tooth that has an active cavity, you’re just going to seal it in there and eventually it’s going to progress to tooth loss,” Truman said.
Dental veneers aren’t the only option for improving the appearance of teeth. Over-the-counter whitening kits can help with minor stains and discoloration. And dentists can sometimes use composite materials to reshape chipped or uneven teeth. But Truman says those fillings are prone to crack and won’t last as long as veneers.
How can I spot bogus veneer providers online?
One clue: Many individuals performing unlicensed dental work promote themselves on social media as “veneer technicians.”
Instead of working out of a dental office they often perform treatments at beauty salons, hotel rooms or private homes. Some advertise multi-city tours and encourage clients to message them to book an appointment in advance.
Much of the appeal of the services is in their pricing, with some offering a full set of veneers for a flat fee of $4,000 or $5,000. That’s less than half of what patients can generally expect to pay at a dental office.
Performing dental work without an appropriate license is illegal, the ADA notes.
Dentists and hygienists are licensed by state governments, who also define the work dental assistants can perform. But in all cases, veneers and other dental procedures must be supervised by a licensed dentist.
Earlier this year, Illinois law enforcement officials arrested a woman running a business called the Veneer Experts after she posted videos of herself fitting braces, veneers and other dental products without a license. She was previously arrested in Nevada on similar allegations of practicing dentistry without a license.
What are the best ways to find legitimate dental providers?
The ADA maintains a website detailing the training and licensing requirements for dentists across the U.S. Most states also maintain websites where you can lookup and verify licensure information and find any past disciplinary actions for dentists and other health professionals.
“It’s really critical to understand that dentistry is a regulated health care profession that requires formal educations and licensure,” Cooper said.
