Ketamine dangers in spotlight after arrests made in actor Matthew Perry’s death
Recent arrests made in actor Matthew Perry’s death have cast new light on the dangers of ketamine abuse.
Perry’s Oct. 28th death — which initially appeared to be a drowning in a hot tub at his California home — was later attributed to the “acute effects of ketamine,” as ruled by the Los Angeles County Department of Medical Examiner.
Several people are now charged in connection with the 54-year-old actor’s overdose death — including Perry’s assistant, Kenneth Iwamasa, who allegedly administered excessive amounts of ketamine — as well as multiple physicians and dealers, who are said to have provided the drug.

On the day of Perry’s death, the “Friends” star received three ketamine injections, according to information in the assistant’s plea agreement.
Here’s a deeper dive into ketamine and the issues around it.

What is ketamine?
Intended for use as an anesthetic to be handled by medical doctors and veterinarians, ketamine is also used illegally as a recreational drug.
The Alcohol and Drug Foundation (ADF) describes ketamine as a “dissociative drug,” which means it causes people to feel “separated or detached” from their bodies or physical surroundings.

For some, it can cause hallucinations and alter people’s thoughts and emotions, according to the ADF.
“Ketamine is in the PCP (phencyclidine) family,” Dr. Marc Siegel, senior medical analyst for Fox News and clinical professor of medicine at NYU Langone Medical Center, told Fox News Digital.
(PCP is a dissociative, mind-altering drug that may lead to hallucinations.)

The off-label use of ketamine has “skyrocketed” in recent years, “despite limited data supporting the safety and efficacy of that practice,” according to a report from Yale School of Medicine.
The drug is usually sold as a colorless, odorless liquid or as a white or off-white powder, according to the National Drug Intelligence Center (NDIC) website.

When used in a powder or liquid form, it is often mixed with beverages or smoked with marijuana or tobacco.
The powder form can also be snorted or pressed into tablets.
As a liquid, ketamine can be injected, the NDIC states.
Ketamine approved for depression in health care setting
In 2019, the U.S. Food and Drug Administration (FDA) approved ketamine in a nasal spray format (Spravato, or S-ketamine) for treatment-resistant depression and suicidal ideation.
It is intended to be used in combination with antidepressant pills only under the supervision of a medical professional.
“S-ketamine is regulated very tightly,” the Yale report stated. “It has to be delivered intranasally, in a certified health care setting under the supervision of a health care professional, and patients must remain in the facility for two hours after dosing.”

Ketamine is more commonly used for treatment of severe depression and for pain management, according to Siegel.

Dr. Justin Gerstner, psychiatrist and chief medical officer at Ellie Mental Health in Minnesota, uses ketamine therapy in his own practice, saying the response from clients has been “great,” as Fox News Digital previously reported.
Ketamine therapy eliminates the need for patients to take medication every day, according to the doctor.

Gerstner’s practice usually administers ketamine to clients via IV injection in two- to three-hour sessions, partnered with psychotherapy before and after treatment, he said. While ketamine can work as a “really powerful anti-depressant and anti-suicidal drug,” it is “not the right answer for everybody or everything,” he previously told Fox News Digital.
When does ketamine become deadly?
There are risks and limitations involved, Gerstner warned — including the potential for ketamine to be abused.
There isn’t too much regulation surrounding how ketamine treatments are administered, Gerstner noted, since the drug was previously approved for anesthetic use.

“The field is wide open, and it’s a little bit like the Wild West,” he said. “This is a really powerful medication and the way that it’s used can vary quite drastically.”
At high doses, the drug can cause adverse health issues that affect cardiovascular, respiratory and neurologic function, which can be fatal, said the American Addiction Centers website.
“Common causes of overdose death include excess sedation, respiratory failure, low blood pressure, cardiac arrhythmia, coma and seizures.”
Some of the risks include elevated blood pressure, difficulty breathing, amnesia, seizures, addiction, problems with judgment and coordination, and a lower urinary tract irritation called ulcerative cystitis, according to the same source.
“Common causes of overdose death include excess sedation, respiratory failure, low blood pressure, cardiac arrhythmia, coma and seizures,” said Siegel.
In Perry’s case, the report stated that given the high levels of ketamine found in his blood, “the main lethal effects” from the ketamine included “cardiovascular overstimulation and respiratory depression.”

Measles outbreak explodes in South Carolina; multiple people hospitalized as cases surpass 200
NEWYou can now listen to Fox News articles!
The South Carolina Department of Public Health (DPH) is sounding the alarm after 26 new measles cases were reported since Friday, bringing the total number of cases in the state’s latest outbreak to 211.
DPH first reported a measles outbreak Oct. 2 in the Upstate region. As of Tuesday, 144 people are in quarantine and seven people are in isolation.
Of the 211 cases, 45 involve children under 5, 143 cases involve children ages 5 to 17, 17 cases involve adults and six cases involve minors whose ages weren’t disclosed.
DPH said 196 of the 211 infected individuals were unvaccinated, four were partially vaccinated, one was vaccinated and 10 are either still being investigated or have an unknown vaccination status.

Officials said 19 of the new cases were associated with “exposures in known households and previously reported school exposures,” and four resulted from church exposures.
DPH identified public exposures at Sugar Ridge Elementary and Boiling Springs Elementary and began notifying potentially exposed students, faculty and staff Dec. 31.
There are nine students in quarantine from the two schools.

Exposures also happened at the Tabernacle of Salvation Church, Unitarian Universalist Church of Spartanburg, Slavic Pentecostal Church of Spartanburg and Ark of Salvation Church.
The source of one case is unknown, while two others are still being investigated.
Although complications from measles are not reportable, officials said four people, including adults and children, required hospitalization for complications from the disease.

Additional cases required medical care, but the infected individuals were not hospitalized.
Those infected with measles are contagious from four days before the rash appears and may be unaware they can spread measles before they know they have the disease, according to DPH.
DPH said it is important for those with a mild illness or those who are in quarantine to stay home to protect others.
“We encourage employers to support workers in following DPH recommendations to stay out of work while ill or in quarantine, which also protects businesses, other workers and clients,” officials wrote in a statement.

DPH said vaccinations continue to be the best way to prevent measles and stop the outbreak.
Though the CDC recently released new vaccine recommendations under Health and Human Services Secretary Robert F. Kennedy Jr., its guidelines still dictate all children should be immunized for measles, mumps, rubella, polio, pertussis, tetanus, diphtheria, Haemophilus influenzae type B (Hib), pneumococcal disease, human papillomavirus (HPV) and chickenpox.

Common pain relievers may raise heart disease and stroke risk, doctors warn
NEWYou can now listen to Fox News articles!
Many might assume that over-the-counter (OTC) medications are generally safer than stronger prescription drugs, but research shows they can still present risks for some.
Certain common OTC painkillers have been linked to an increased risk of high blood pressure, stroke and heart attacks.
Potential risk of NSAIDs
Non-steroidal anti-inflammatory drugs (NSAIDs) — which are used to reduce pain, fever and inflammation — have been pinpointed as the class of medicines most linked to elevated cardiovascular risk.
NEW HEALTH WARNING ISSUED OVER POPULAR SLEEP AID MILLIONS TAKE NIGHTLY
“This is because they reduce the production of certain chemicals called prostaglandins,” Maryam Jowza, M.D., an anesthesiologist at UNC Health in North Carolina, told Fox News Digital. “These chemicals are involved in inflammation, but they are also involved in other body functions, such as influencing the tone of blood vessels.”

Dr. Marc Siegel, Fox News senior medical analyst, echoed the potential risk of NSAIDs.
“They can lead to high blood pressure, heart attack and stroke via fluid retention and salt retention,” he told Fox News Digital. “This increases volume, puts a strain on the heart and raises blood pressure.”
DIABETES PATIENTS EXPERIENCE LOWER DEATH RATE WITH COMMON MEDICATION
Common examples of NSAIDs include ibuprofen, naproxen, aspirin, diclofenac, indomethacin and celecoxib.
Randomized trials found that ibuprofen caused the biggest spikes in blood pressure, followed by naproxen and then celecoxib.
“In general, the increase in blood pressure is more likely with higher doses and longer duration of treatment,” said Jowza, who is also an associate professor in the Department of Anesthesiology at the UNC School of Medicine.
COMMON VIRUSES LINKED TO ‘DRAMATIC’ SPIKE IN HEART ATTACK AND STROKE RISK
NSAIDs can also increase stroke risk, especially at high doses and with long-term use, the doctor added.
Diclofenac was linked to the highest cardiovascular risk, the doctor cautioned. Ibuprofen can also raise blood pressure and has been associated with a higher heart attack and stroke risk, but not as high as diclofenac. Naproxen carries a lower cardiovascular risk than ibuprofen or diclofenac, but is not entirely risk-free.

“The practical takeaway is that diclofenac is generally the least favorable choice in patients with elevated cardiovascular risk, and all NSAIDs should be used at the lowest effective dose for the shortest duration,” Dr. Nayan Patel, pharmacist and founder of Auro Wellness in Southern California, told Fox News Digital.
COMMON VITAMIN COULD PROTECT SOME HEART ATTACK SURVIVORS, STUDY SHOWS
Aspirin is an exception — although it is an NSAID, it actually reduces the risk of clots when taken at a low dose for prevention, under a doctor’s guidance. However, it can increase bleeding risk and blood pressure at high doses.
Non-NSAIDs safer, but not risk-free
Non-NSAID pain relievers are commonly used for everyday aches, headaches and fever, but not swelling. They act mainly on the brain’s pain signals, not inflammation, according to medical experts.
Acetaminophen, the most common non-NSAID pain reliever, is also linked to an increase in blood pressure, although to a lesser extent, according to Jowza.
“All NSAIDs should be used at the lowest effective dose for the shortest duration.”
“Acetaminophen was once thought to have little to no cardiovascular effects, but more recent evidence suggests it can increase blood pressure, especially with higher doses used in the long term,” she said, emphasizing the importance of blood pressure monitoring. “Its effect on stroke risk is less clear.”
Which groups are most vulnerable?
The groups at greatest risk, according to doctors, are those with existing health conditions, such as high blood pressure, prior stroke or heart disease, diabetes or kidney problems.
“These groups are also more likely to experience NSAID-related fluid retention and destabilization of blood pressure control,” Patel said.

Cardiovascular risk is generally higher for people 75 and older, the doctors agreed.
“Age amplifies risk largely because baseline cardiovascular risk increases with age, and kidney function reserve tends to decline,” Patel said. “Older adults are also more likely to be on antihypertensives, diuretics, antiplatelets or anticoagulants, so NSAIDs can destabilize blood pressure control and add safety complexity.”
Warning signs
Anyone experiencing chest pain, shortness of breath, sudden weakness or numbness, severe headache, confusion, slurred speech or vision changes should see a doctor immediately, Jowza advised.

“These symptoms can point to a heart attack or stroke,” she warned. “Other symptoms of concern that may not develop as rapidly, like new swelling in the legs, should also prompt medical attention.”

“Patients should also seek medical advice if they notice signs of fluid retention or kidney stress, such as rapidly rising blood pressure, swelling in the legs, sudden weight gain over a few days, reduced urine output or worsening shortness of breath,” Patel added.
Safer alternatives
For those at higher risk, Patel recommends non-NSAID approaches whenever possible.
“For many patients, this means starting with non-drug strategies such as heat or ice, physical therapy and activity modification,” he told Fox News Digital. “If medication is needed, acetaminophen is generally preferred over oral NSAIDs from a cardiovascular standpoint, although regular use should still be monitored in people with hypertension.”

For localized joint or muscle pain, the doctor said topical NSAIDs can offer “meaningful relief” with “far lower” risk.
“Overall, pain management in high-risk patients should emphasize targeted therapy, conservative dosing and close blood pressure monitoring.”
Bottom line
The doctors emphasized that the overall risk is “very low” for people taking OTC pain relievers on a short-term basis, but it rises with long-term, high-dose use.

“I would not hesitate to use an occasional dose if it were a low-risk individual with no prior history of heart attack or stroke,” Jowza said. “I also think short-term use in diabetics and hypertensives who are well-controlled is acceptable.”

For those taking NSAIDs, the doctor suggested using “guard rails” — such as regularly testing blood pressure and kidney function, and setting limits on dosing — to make treatment as safe as possible.
Patel agreed that for most healthy individuals, occasional NSAID use “does not carry a meaningful cardiovascular risk.”

“The concern is primarily with repeated or chronic use, higher doses, and use in people with underlying cardiovascular, kidney or blood pressure conditions,” he confirmed to Fox News Digital.
“That said, large population studies show that cardiovascular events can occur early after starting NSAIDs, particularly at higher doses, which is why even short-term use should be approached cautiously in higher-risk patients.”

Flu hospitalizations hit all-time weekly high in densely populated state, officials warn
NEWYou can now listen to Fox News articles!
The New York State Department of Health has announced the highest number of flu hospitalizations recorded in a single week.
The state confirmed the uptick in hospital visits in a press release on Jan. 2, as flu cases continue to rise in the region and nationwide.
New York State, including New York City, has consistently tracked the highest numbers of recorded respiratory illness cases in the country for the last few weeks, according to CDC data. Several other states have climbed to the “very high” category for respiratory activity as well, as of the week ending Dec. 27.
RECORD-BREAKING FLU NUMBERS REPORTED IN NEW YORK STATE, SPARKING WARNINGS FROM OFFICIALS
The most recent data from the New York health department showed a total of 4,546 hospitalizations from Dec. 26, 2025, to Jan. 2, 2026 – a week-over-week increase of nearly 1,000. The prior week, the department announced the highest number of flu cases ever recorded in a single seven-day period.

In a statement, New York’s Acting Commissioner of Health Dr. James McDonald noted the severity of this flu season compared to previous years.
“Almost 1,000 more people were admitted to a hospital during this most recent seven-day period compared to the prior week,” he confirmed. “There is still time to get a flu shot, and remember, flu can be treated with antiviral medication if started within 48 hours of symptom onset [as] your doctor deems appropriate.”

In a previous interview with Fox News Digital, Dr. Neil Maniar, professor of public health practice at Boston’s Northeastern University, emphasized that it’s not too late to get the flu vaccine, as peak season typically occurs in January.
“The vaccine still provides protection against serious illness resulting from the subclade K variant that seems to be going around,” he said.

Even healthy individuals can become seriously ill from the flu, Maniar noted, “so a vaccine is beneficial for almost everyone.”
“Individuals typically start to develop some degree of protection within a few days and gain the full benefit within about two weeks, so now is the time for anyone who hasn’t gotten the vaccine yet.”
“The vaccine still provides protection against serious illness resulting from the subclade K variant that seems to be going around,” one doctor said. (iStock)
Flu symptoms can include fever, chills, headache, fatigue, cough, sore throat and runny nose.
A mutation of influenza A H3N2, called subclade K, has been detected as the culprit in rising global cases, causing more intense symptoms and higher risk of spread.
