Herbal Pain Relief Tea Recalled for Having Undeclared Drugs

By Pat Anson, PNN Editor

“Alleviates Pain & Inflammation Within 10 Minutes”

“Drug-Free All Natural Herbal Pain Relief”

As the saying goes, if the ads sound too good to be true, they probably are. Especially the part about being “drug-free.”

An herbal tea being marketed as a pain reliever for arthritis, gout, fibromyalgia and migraine is being voluntarily recalled after the Food and Drug Administration found that it contained “undeclared drugs.”

WS Global, a New York-based distribution company, is recalling all packages of Himalayan Pain Relief Tea after being informed by the FDA that the tea contains diclofenac, a non-steroidal anti-inflammatory drug (NSAID) and dexamethasone, a corticosteroid.

The company said it had not received any reports of adverse events involving the tea, but urged consumers to “immediately consult their health care professional” if they consumed it.

In a news release, the FDA said diclofenac may raise the risk of cardiovascular events, such as a heart attack or stroke, and could interact with other medications.

Dexamethasone can suppress the adrenal gland, impair a person’s ability to fight infections, and cause high blood sugar, muscle injuries and psychiatric problems. It may also have serious side effects when combined with other medications.

Neither diclofenac or dexamethasone are mentioned on the tea’s product label or advertising. The company claims the tea was “formulated by a traditional comprehensive recipe from the Himalayan monks.”

Himalayan Pain Relief Tea was being sold online, primarily through Amazon.

This is not the first time that an herbal or dietary supplement sold by Amazon was recalled due to undeclared drugs, contamination or other health concerns. In recent months, recalls were also ordered for a male sexual enhancement product, a glucose supplement, apple sauce, and an anti-cavity mouthwash for kids. All were being sold on Amazon.  

In a recent warning letter to Amazon’s CEO about selling several brands of unapproved eye drops, the FDA said the company should take more responsibility for the products it sells.

“The violations cited in this letter are not intended to be an all-inclusive statement of past or present violations that may exist in connection with the products you distribute. You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations. It is your responsibility to ensure that your firm complies with all requirements of federal law, including FDA regulations,” said Jill Furman, Director of the FDA Office of Compliance, Center for Drug Evaluation and Research.

Amazon complied with that request by removing the eye drops from its online marketplace.

“Safety is a top priority at Amazon. We require all products offered in our store to comply with applicable laws and regulations,” the company said in a statement.

Amazon received a similar warning letter in 2022, for selling a “misbranded” dietary supplement for arthritis that was linked to liver toxicity and at least one death. That product also contained diclofenac and dexamethasone.

You can still find Himalayan Pain Relief Tea on Amazon, with a notation that it is “currently unavailable.”

“We don't know when or if this item will be back in stock,” Amazon cautions potential buyers.

Women, Children and Some Ethnic Groups at More Risk from NSAID

By Pat Anson, PNN Editor

Health experts have known for over a decade that diclofenac, a non-steroidal anti-inflammatory drug (NSAID), raises the risk of heart failure, stroke and other cardiovascular problems. Because of that, oral formulations of diclofenac are only available by prescription in the U.S. and some European nations, although the drug is still widely available as an over-the-counter pain reliever in Asia, Africa and the Middle East.

“Most patients who are using diclofenac have arthritis, and many of them are at risk of heart disease,” says Bhagwat Prasad, PharmD, an associate professor in the Washington State University College of Pharmacy and Pharmaceutical Sciences. “So there is a concern that taking diclofenac may be putting them at even greater risk of cardiovascular events such as heart attack and stroke.”

Prasad is senior author of a study, recently published in the journal Clinical Pharmacology & Therapeutics, that found women, children and some ethnic groups are more at risk from diclofenac because they have low levels of an enzyme that helps metabolize the drug in their intestines.

The enzyme – known as UGT2B17 – is present at much lower levels in women than in men, which helps explain why there are more reports of women suffering heart damage after taking diclofenac. UGT2B17 is mostly absent in children under the age of nine.

Ethnic differences also play a role. In studies on human liver and intestinal samples, WSU researchers found that up to 90% of people of Japanese descent lack the gene for the enzyme, compared to just 20% of Caucasian people.

“No one knew why this heart toxicity is happening in some individuals,” said first author Deepak Ahire, a graduate student in the WSU College of Pharmacy and Pharmaceutical Sciences. “Our study showed, for the first time, that UGT2B17 is important in diclofenac metabolism and suggests that differences in UGT2B17 expression are what makes people’s response to diclofenac so variable, leading to toxicity in some whereas for others the drug simply does not work.”

Ahire and his colleagues hope to confirm their findings in a clinical trial. They also want to work with large hospitals to further study the connection between diclofenac and patients with heart problems. One way they suggest to reduce the risk of cardiovascular problems is to use genetic testing to screen patients who may have problems metabolizing diclofenac.

According to the FDA’s Adverse Events Reporting System, there have been over 27,000 serious medical cases involving diclofenac since 2010, including 2,827 deaths. The number of U.S. cases has tripled in recent years, with women involved in nearly twice as many adverse events as men.

In 2020, the FDA approved the use of diclofenac in Voltaren, a topical OTC gel that contains a small dose of diclofenac absorbed through the skin. The WSU study involved higher dose diclofenac tablets that are taken orally and absorbed in the digestive system. About half the prescriptions written for diclofenac in the U.S. are for tablets.

A large 2018 study in Denmark found that people who used diclofenac were 50 percent more likely to have cardiovascular problems within 30 days of taking the drug than those who took nothing. The risk of gastrointestinal bleeding was also higher. The authors of that study recommended that diclofenac not be available OTC and should only be prescribed with prominent warning labels.

Pregnant Women Raise Risk of Complications by Using OTC Pain Relievers

By Pat Anson, PNN Editor

Pregnant women who take over-the-counter pain relievers are one-and-a-half times more likely to have complications, including stillbirth and premature delivery, according to a large new study.

Researchers at the University of Aberdeen analyzed data from over 151,000 pregnancies in the UK from 1985-2015, looking for medical notes indicating the women used paracetamol (acetaminophen), aspirin or the non-steroidal anti-inflammatory drugs (NSAIDs) diclofenac, naproxen and ibuprofen — either alone or in combinations.

The findings, recently published in BMJ Open, show a significantly higher risk of a preterm delivery, neonatal death, low birth weight and other health problems in babies born to mothers who used OTC pain relievers. Neural tube defects of the brain, spine or spinal cord were 64% more likely; while hypospadias, a birth defect affecting the penis, was 27% more likely.

“Over-the-counter analgesics consumption during pregnancy was associated with a substantially higher risk for adverse perinatal health outcomes in the offspring. The use of paracetamol in combination with other non-steroidal anti-inflammatory drugs conferred the highest risk,” wrote lead author Aikaterini Zafeiri, PhD. “The increased risks of adverse neonatal outcomes associated with non-prescribed, over-the-counter, analgesics use during pregnancy indicate that healthcare guidance for pregnant women regarding analgesic use need urgent updating.”

One of the more surprising aspects of the study is how use of the five analgesics by pregnant women grew dramatically over the 30-year study period.  In 1985, only 1.8% reported using one of the pain relievers. By 2015, that had grown to 70.6% -- with most of the increase coming in the last seven years of the study.

Although it is believed to be one of the largest and most comprehensive studies of its kind, the research was limited. The duration, dose and stage of the pregnancy when analgesics were consumed were not recorded. The health of the mothers and babies later in life was also not studied.

But given the substantial increase in analgesic use during pregnancy and the higher risk of complications, researchers say more caution is needed on use of the drugs.

“The ease of access to non-prescription painkillers, in combination with availability of misinformation as well as correct information through the internet, raises safety concerns,” said Zafeiri. “It should be reinforced that paracetamol in combination with NSAIDs is associated with a higher risk and pregnant women should always consult their doctor or midwife before taking any over-the-counter drugs. We would encourage a strong reinforcement of the official advice for pregnant women.”   

Previous studies have linked prenatal use of paracetamol to autism, hyperactivity and behavioral problem in children. Despite the findings, drug regulators in the UK and US maintain that it is safe for pregnant women to use paracetamol (acetaminophen).

“Paracetamol is the first choice of painkiller if you're pregnant or breastfeeding. It's been taken by many pregnant and breastfeeding women with no harmful effects in the mother or baby,” the UK’s National Health Service (NHS) says on its website.

The Food and Drug Administration also does not caution pregnant women about using acetaminophen. The agency said in 2015 that the evidence was “too limited” to justify such a warning.  

Meanwhile, drug regulators in Australia are so concerned about recent deaths involving paracetamol that they may restrict access to the drug. Australia’s Therapeutic Goods Administration (TGA) has commissioned a report by an expert panel on the risks of paracetamol misuse.

“While paracetamol has well established safety and toxicity profiles, the wide use is paralleled by a high prevalence of accidental and deliberate paracetamol poisoning in the community, in both adults and children,” the TGA said in a statement earlier this month.

“The TGA is aware of concerns, particularly of families and healthcare professionals of affected consumers of paracetamol, regarding the number of poisonings and deliberate overdoses from paracetamol obtained from general retail outlets, and whether current access restrictions are appropriate.”

Australia currently regulates the quantity and dose of paracetamol sold over-the-counter. The independent commission will consider if stricter buying limits should be imposed. 

Voltaren Arthritis Gel Approved for OTC Despite Safety Risks

By Pat Anson, PNN Editor

The U.S. Food and Drug Administration has approved three drugs for over-the-counter (OTC) sale that were previously only available by prescription. One of them is Voltaren Arthritis Pain, a topical gel made by GlaxoSmithKline.

The active ingredient in Voltaren gel is diclofenac, a non-steroidal anti-inflammatory drug (NSAID) that’s been linked to cardiovascular disease and other serious health problems. The gel contains a 1% solution of diclofenac sodium.

Voltaren Arthritis Pain was first approved by the FDA in 2007 as a prescription drug for the temporary relief of osteoarthritis joint pain in the hands, knees and feet. When taken as directed, the agency considers the gel safe to use.

“As a result of the Rx-to-OTC switch process, many products sold over-the-counter today use ingredients or dosage strengths that were available only by prescription 30 years ago,” said Karen Mahoney, MD, acting deputy director of the Office of Nonprescription Drugs in the FDA’s Center for Drug Evaluation and Research.

“Approval of a wider range of nonprescription drugs has the potential to improve public health by increasing the types of drugs consumers can access and use that would otherwise only be available by prescription. This includes providing the millions of people that suffer with joint pain from arthritis daily over-the-counter access to another non-opioid treatment option.”

The FDA said Voltaren Arthritis Pain may take up to 7 days to work. Consumers should stop using it and seek medical attention if their arthritis pain is not improved in 7 days or if they need to use the product for more than 21 days.

The warning label cautions that diclofenac may cause a severe allergic reaction, especially in people allergic to aspirin. Liver damage may also occur if the gel is used more often or longer than directed, or when used with other products containing diclofenac. The label cautions that diclofenac and other NSAIDs increase the risk of heart attack, heart failure and stroke.

Diclofenac One of Riskiest NSAIDs

Diclofenac is not well-known in the United States, but it is the most widely used NSAID in the world. Some experts consider diclofenac so risky it should be banned as an OTC drug.

A large 2018 study in Denmark found that people using diclofenac were 50 percent more likely to have cardiovascular problems, such as atrial fibrillation, heart failure and stroke.

For every 1,000 people who used diclofenac, the study estimated that four would develop a major health problem within a year.

“It is time to acknowledge the potential health risk of diclofenac and to reduce its use. Diclofenac should not be available over the counter.”

— Dr. Morten Schmidt, Aarhus University Hospital

"It is time to acknowledge the potential health risk of diclofenac and to reduce its use," wrote lead author Morten Schmidt, MD, Aarhus University Hospital. “Diclofenac should not be available over the counter, and when prescribed, should be accompanied by an appropriate front package warning about its potential risks.”

Diclofenac was rated as one of the seven riskiest NSAIDs in a 2016 study published by the British Medical Journal. Researchers estimated the risk of heart failure doubled for people taking diclofenac at very high doses.

“The selective COX 2 inhibitors and diclofenac have repeatedly been associated with higher cardiovascular risk, and therefore it seems prudent to avoid them and consider lower risk naproxen at the lowest effective dose,” researchers warned.

According to the FDA’s Adverse Events Reporting System, there have been over 19,000 serious medical cases involving diclofenac sodium since 2010, including 2,294 deaths.  

As PNN has reported, the FDA has effectively slammed the door shut on new opioid pain medications because of the controversy over opioid addiction and overdose. The agency is promoting the use of “safer” non-opioid drugs and recently approved a cocaine-based analgesic nasal spray.

Widely Used Painkiller Raises Risk of Heart Problems

By Pat Anson, Editor

The most widely used painkiller in the world should be banned as an over-the-counter drug because it significantly raises the risk of cardiovascular problems and gastrointestinal bleeding, according to a large new study published in the British Medical Journal (BMJ).

Diclofenac is not well-known in the United States, but it is the most widely used non-steroidal anti-inflammatory drug (NSAID) in the world. It is sold both as a prescription and over-the-counter medication under various brand names such as Voltaren, Cambia, Zorvolex and Solaraze.

Researchers looked at healthcare data from over 6 million people in Denmark from 1996 to 2016 and found that those who used diclofenac were 50 percent more likely to have cardiovascular problems such as atrial fibrillation, heart failure and stroke in the first 30 days compared to those who took nothing. Their risk of gastrointestinal bleeding was also higher.

Out of every 1,000 people who used diclofenac, the study estimated that four additional people would develop a major health problem within a year.

"It is time to acknowledge the potential health risk of diclofenac and to reduce its use. Diclofenac should not be available over the counter, and when prescribed, should be accompanied by an appropriate front package warning about its potential risks," wrote lead author Morten Schmidt, MD, Aarhus University Hospital.

"Treatment of pain and inflammation with NSAIDs may be worthwhile for some patients to improve quality of life despite potential side effects. Considering its cardiovascular and gastrointestinal risks, however, there is little justification to initiate diclofenac treatment before other traditional NSAIDs."

This is not the first time that researchers have warned about the health risks associated with diclofenac and other NSAIDs.

In 2016, researchers at 14 European universities and hospitals, including a number of leading heart specialists, warned that some NSAID’s raise cardiovascular risk and that there is no "solid evidence" the drugs are safe.

Some of the greatest cardiovascular risk comes from a class of NSAIDs known as COX-2 inhibitors. A COX-2 inhibitor called Vioxx was voluntarily pulled from the market by Merck in 2004, but many other COX-2 inhibitors, such as diclofenac, are still widely used for pain relief.   

Another 2016 study published in the BMJ found that use of any NSAID was associated with a 20 percent higher risk of being hospitalized with heart failure. These seven NSAIDs were found to be the riskiest:

• diclofenac
• ibuprofen
• indomethacin
• ketorolac
• naproxen
• nimesulide
• piroxicam

NSAIDs are used to alleviate pain and reduce inflammation, and are found in a wide variety of over-the-counter products – from headache relievers to cold and flu remedies. They are used in so many different products -- such as Advil and Motrin -- that many consumers may not be aware how often they use NSAIDs. 

In 2015, the U.S. Food and Drug Administration ordered warning labels for all NSAIDs to be strengthened to indicate they increase the risk of a fatal heart attack or stroke. The FDA said studies found the risk of serious side effects can occur in the first few weeks of using NSAIDs and could increase the longer people use the drugs. The revised warning does not apply to aspirin.

The European Society of Cardiology recommends limited use of NSAIDs by patients who are at increased risk of heart failure. Those already diagnosed with heart failure should refrain from using NSAIDs completely.

Aleve & Other Pain Relievers Reduce Fertility in Women

By Pat Anson, Editor

Health experts have warned for years about the side effects of over-the-counter pain relievers – everything from liver failure to heart disease to hearing loss.

Now researchers are saying that Aleve and some other non-steroidal anti-inflammatory drugs (NSAIDs) reduce the fertility of women so significantly they could potentially be used as an emergency form of contraception.

The results of a small study presented at the European League Against Rheumatism Annual Congress show that three NSAIDs --  naproxen, diclofenac, and etoricoxib -- inhibited ovulation in women after just a few days of treatment.

Naproxen, diclofenac, and etoricoxib are the active ingredients in several brand name drugs sold around the world, including Aleve, Voltaren, and Arcoxia, respectively. Etoricoxib is not approved for use in the United States.

Thirty nine Iraqi women of childbearing age who suffered from back pain took part in the study; receiving diclofenac (100mg once daily), naproxen (500mg twice daily), etoricoxib (90mg once daily), or a placebo.

Treatment was given for 10 days from day 10 of the onset of their menstrual cycle, with their progesterone levels and follicle diameter analyzed via blood sample and sonography.

“After just ten days of treatment we saw a significant decrease in progesterone, a hormone essential for ovulation, across all treatment groups, as well as functional cysts in one third of patients,” said study investigator Professor Sami Salman, Department of Rheumatology, University of Baghdad.

“These findings show that even short-term use of these popular, over-the-counter drugs could have a significant impact on a woman's ability to have children. This needs to be better communicated to patients with rheumatic diseases, who may take these drugs on a regular basis with little awareness of the impact.”

Of the women receiving NSAIDs, only 6.3% taking diclofenac, 25% taking naproxen, and 27.3% taking etoricoxib ovulated, compared with 100% of the control group that was not taking a pain reliever.

The dominant follicle remained unruptured in 75% of the women taking diclofenac, 25% taking naproxen and 33% of the patients receiving etoricoxib. Rupturing of the dominant follicle and the subsequent release of an oocyte (unfertilized egg), is essential for ovulation to occur.

“These findings highlight the harmful effects NSAIDs may have on fertility, and could open the door for research into a new emergency contraception with a more favorable safety profile than those currently in use,” said Salman.

NSAIDs are among the most common pain relief medicines in the world. Every day more than 30 million Americans use them to relieve pain, lower fever and reduce inflammation.
