Our culture tends to avoid thinking about death. Even though we know it is inevitable, we tend to act as though it doesn’t actually pertain to us. As a result, most of us have spent little time learning how people find hope and meaning at life’s end. The intense dreams and visions that dying people report may seem strange. In this interview, hospice doctor Christopher Kerr shares his research on this unusual topic.

Helping People Find Hope and Meaning at Life’s End:
Dr. Kerr begins our interview with a description of his father’s death and how it affected him at age 12. In that sense, he says, the topic of dying chose him. Nonetheless, he was unprepared when he accepted a position as a hospice doctor. It wasn’t a topic that was covered in medical school, so he learned from his patients and from the nurses caring for them. In one of his first encounters, he thought that providing the optimal medical care he had ordered for a patient with AIDS would buy him some time. But the nurse suggested that the patient dreaming repeatedly and intensely about his mother suggested instead that he was actively dying. She was right. He came to appreciate the power of the visions and dreams people have leading up to the moment of death.
Studying Pre-death Dreams and Visions:
Dr. Kerr felt that it was crucial to study this phenomenon objectively, recognizing that as the only way to get his medical colleagues to take the topic seriously. He also felt it was essential to center the patient’s experience. In his first study, patients responded to standardized questions about their dreams. Their answers, however, were far from standard.
We Die as We Have Lived:
One thing that Dr. Kerr recognized is that there is continuity between people’s lives and their deaths. The people and themes that were important during their lives most frequently show up in the visions they report as they near death. Many hospice patients find their dreams of deceased relatives very comforting. Others find that their dreams, which may be extremely intense, help them come to peace with traumatic events earlier in their lives.
Sometimes such visions are attributed to confusion, dementia or delusion caused by illness. In contrast, Dr. Kerr and his team found that people with dementia rarely report this type of vision. To provide perspective for those analyzing the dreams, he had the interviews with patients videotaped. Observers can see that patients reporting their experience are cogent and coherent, not at all confused. Being able to understand how these dreams help patients find hope and meaning at life’s end is also valuable to their families. Health professionals can also provide patients with better support if they learn how to value such visions.
Helping Families Deal with Impending Death:
The “silos” in our health care system may not always serve patients and their families very well. Dr. Kerr described an instance in which the family was told that the imaging showed that the tumor was not progressing. The doctor recommended that the patient return in two months for a follow-up study. Yet this patient was sleeping most of the time and eating less than a quarter of his usual servings. As a result, he was losing weight and strength. For the family, learning that the patient was dying helped them shift to showing him that he was loved rather than focusing on a cure.
Children’s Visions at Life’s End:
Dr. Kerr was concerned about how he would address the topic of death with Jessica, a patient who was only 13 years old. He did not have to. She told him that her dead dog Shadow came to her in her dreams, running and playing as he had when he was healthy. That made her happy, and she also told Dr. Kerr that she was not afraid that she would be alone. She was sure Shadow would be there with her.
An Old Soldier Finds Meaning at Life’s End:
One of Dr. Kerr’s patients was a veteran of World War II. As a very young man, he had participated in D-Day. On Omaha Beach, he was responsible for collecting the wounded. He tried to get them back to the ship where they could be treated. But many men did not survive that battle, and the sea ran red with blood. The horror of this experience had haunted him ever since. He would not discuss what he had seen with his children, but his wife knew that he often woke screaming from nightmares.
During his time in hospice, he had two dreams that helped him find hope and meaning at life’s end. One helped him relive the day he got his discharge papers from the Army. In the other, he saw the men that he had rescued and those he had not been able to rescue. They told him they’d be coming for him soon. That sounds terrifying, but he found it comforting. They made it clear that he was one of them, appreciated and loved. Consequently, the guilt he had felt his entire life about not saving them was gone.

For years, the reigning paradigm in health care has been “Doctor knows best.” Providers rarely sought input from patients about their needs or experience. That picture has been changing, though, as more people have been using online tools to band together and find solutions for themselves and their loved ones. Susannah Fox describes the patient-led revolution in health care.

The Patient-led Revolution in Health Care:
Joe, Terry and Susannah witnessed the birth of the participatory medicine movement. Dr. Tom Ferguson inspired it. He networked with physicians, patients, anthropologists and anyone else who was interested in helping health care become more accessible and attuned to patients’ needs.  Doc Tom was convinced that ePatients could make health care better. Susannah Fox shows how many patients have figured out ways to make their needs more visible and get them met.
Seekers on the Hunt:
What do people do when faced with a new diagnosis or an unexpected health development? Some rely on whatever their physician or health care provider may tell them, but others feel like they’ll have more control if they can learn as much as possible about their situation. These people are Seekers, hunting down the information that they need to understand what is happening.
Susannah shares the story of Dave deBronkart, ePatient Dave. He became a Seeker when he received a diagnosis of a potentially deadly kidney cancer.  His primary care physician referred him to an online cancer patient support group through ACOR at the same time he was referred to an oncologist. The patients in the kidney cancer group told him about a treatment that might be appropriate. Dave followed up and it saved his life. He has now become an advocate for the patient-led revolution.
Networkers and the Online Diabetes Community:
Another aspect of the patient-led revolution comes clear with the story of Dana Lewis. Dana lives with type 1 diabetes and is therefore susceptible to the possibility of hypoglycemia while she sleeps. People with diabetes call this situation “dead in bed.” She has a continuous glucose monitor that can tell if her blood sugar drops too low, but its alarm wasn’t loud enough to wake her from a deep sleep. Dana is a Networker, so she learned from the online community about a way to hack into her device and get it to trigger an alarm loud enough to save her life.
Solvers Finding Ingenious Solutions:
The person who first figured out how to get the data from a continuous glucose monitor was a father trying to care for his child with type 1 diabetes. Networkers made sure anyone participating in the community could benefit from his discovery. The online diabetes community has made strides in getting access to the data these devices generate. People with other conditions, such as atrial fibrillation, have had less success so far.
Tal Golesworthy is another example of a Solver. In his work, he deals with boilers. He lives with Marfan’s syndrome, a rare disease that results in weakened cartilage not only in joints but in the aorta. His doctors had suggested an invasive surgery to address this condition, but Tal wondered whether treating it as a plumbing problem might work. He designed a device to wrap around the base of the aorta and reinforce it. The surgery to install it is far less complicated, and many other patients with Marfan’s syndrome have now benefited from the solution he came up with.
Research in the Patient-Led Revolution:
Patients are often aware of problems that providers have overlooked. Sometimes they band together to propose research that could help them cope with such situations. One of the most striking examples is Long COVID research. Patients participated in developing the protocol for an important study published in Nature Reviews Microbiology (April 17, 2023).  It is unusual for patients to be involved in research to this extent. Often, patient groups have difficulty obtaining funding or getting their findings published where providers can learn from them. For that, they need Champions with access to resources such as money or scientific credibility. Dr. Eric Topol of the Scripps Institute was the Champion for the long COVID study.
Patients Getting Access to Their Data:
We already mentioned the diabetes online community finding ways to get access to their blood glucose data. Susannah describes the lengths patient Hugo Campos went to so that he could learn to manage the data from his implanted defibrillator. Most often, patients participating as volunteers for clinical trials do not have access to the data generated about them and their health. The informed consent documents often state that data belongs to the investigators, not the participants.

The term “homeostasis” was coined about a hundred years ago. What does it mean? Essentially, it is a way of describing how various systems in the body work together to maintain internal equilibrium even in the face of a changing environment. This concept is crucial to good health, as healers have known intuitively for millennia.

Why Survival Depends on Natural Balance:
Ancient Greek physicians recognized that natural balance within the body was essential. They worked out a complex explanation in which four “humors” determined a patient’s health. We don’t believe in their explanation any more, but we still recognize that disrupting one part of the system will likely lead to changes in other areas to try to compensate. To understand what is happening, we need to consider the entire organism.
One expert, Dr. George Billman, explained it like this:
“It is no more possible to appreciate the beauty of de Vinci’s “Mona Lisa” or Van Gogh’s “The Starry Night” by removing and analyzing each individual dab of paint than we can understand how the various organ systems work together to maintain health by examining single genes or molecules.”
What Drugs Do to Homeostasis:
Appreciating the natural balance of our bodies may be harder when considering prescription drugs. Powerful pharmaceuticals are meant to correct pathways that are not functioning properly. However, they may also interfere with homeostasis. Sometimes they block appropriate absorption or utilization of nutrients. At other times, they may result in dysbiosis–an imbalance of the microbiome.
Another difficulty with potent drugs is that the body may adapt to the drug itself. Then, if the drug is discontinued abruptly, there is a rebound effect. This can be extremely uncomfortable, not to mention disconcerting. Many people may be aware that stopping an anti-anxiety drug suddenly can make them feel anxious and ill. But that is not the only example. Another common problem occurs when a person stops a powerful acid-suppressing drug such as omeprazole. Rebound hyperacidity resulting in heartburn symptoms is not unusual.
Maintaining the Natural Balance of the Microbiome:
Our bodies host a tremendous collection of microbes, including a wide range of bacteria, viruses and even fungi. We know the most about the microbiome of our digestive systems, although our skin, our lungs and pretty much every other body part also has its own unique microbiome.
When the microbiome goes out of balance, it becomes susceptible to even more extreme disruption. We think that’s what happens when Clostridium difficile (C. diff) becomes a problem. Although people talk about C. diff infections causing dreadful diarrhea, in most cases the C. diff was there at a low level all along, as part of the normal complement of microbes in the gut. However, when other bacteria are killed off, by a round or two of antibiotics, for example, C. diff seizes the opportunity and takes over. As a result, treating C. diff with more antibiotics isn’t always helpful and sometimes makes things worse. What is needed is a way to restore the natural balance of the microbiome.
Understanding Homeostasis:
This explanation of C. diff illuminates why understanding homeostasis is so important. Since gastroenterologists deal with the microbiome all the time, we trust that they are paying close attention to maintaining natural balance. But our guest, Dr. Robynne Chutkan, admits that her colleagues often prescribe drugs such as PPIs that upset the balance of the microbiome and result in dysbiosis.
Rebuilding Natural Balance as the Path to Health:
PPIs are certainly not the only medications that can cause trouble for the microbiome. Popular pain relievers known as NSAIDs have an impact on intestinal microbes and can also affect the gut lining. When it becomes more permeable, other illnesses arise. Restoring health requires us to consider the entire context of the individual.

This week, Joe and Terry Graedon welcome your questions and stories about the dangers of overdosing on OTC meds.

You can ask your questions about OTC drug safety and share your experience at 888-472-3366 between 7 and 8 am EDT. We receive email at radio@peoplespharmacy.com.

The Dangers of Overdosing on OTC Meds:
For most of us, the first thing we turn to when we notice a minor medical problem is a nonprescription medicine. Why wouldn’t we? Drugstores, quick marts, vending machines and other places offer as many as 300,000 such products for a wide range of symptoms. According to the FDA, these drugs can be used for self-diagnosed conditions, don’t need a healthcare practitioner to supervise their use and have a low likelihood of abuse or misuse. OTC drugs are usually affordable and don’t require seeing a prescriber.
That might not mean they are completely safe, though. About 95% of the products that are currently sold over the counter once required a prescription. The FDA decided that they were safe enough not to need expert monitoring. Presumably, patients/consumers are undertaking the necessary monitoring themselves. How do they know what to watch for?
Consumer Information on OTC Meds:
Do you read the Drug Facts on the label of your over-the-counter meds? Generally, this will tell you about the active ingredient and may also include a list of inactive ingredients. It should list its use. For example, the label for Prilosec OTC states: “treats frequent heartburn (occurs 2 or more days a week)” and cautions that it will not provide immediate relief.
Drug Facts also include important warnings. These may be somewhat esoteric, as in the warning about glucose-6-phosphate dehydrogenase deficiency on a box of phenazopyridine for urinary pain relief. If you have G6PD deficiency, you’ll know the warning is important. Those who do not may well wonder about it briefly and then forget it. Other warnings appear more generally. Products containing salicylates, including aspirin and Pepto-Bismol, caution against giving them to children or teenagers with chickenpox or the flu. That could result in Reye’s syndrome, “a rare but serious illness.”
Prescription to OTC:
You are probably aware that prescription drugs generally come with a lengthy list of side effects. Take Prilosec (omeprazole) as just one example. The prescribing information for this important medication used to treat ulcers, erosive esophagitis, Zollinger-Ellison syndrome and GERD lists more than 100 adverse reactions. Some of them are extremely serious, such as anaphylactic shock, angioedema, pancreatitis and liver failure. The package containing Prilosec OTC does not list any side effects directly. It does suggest you stop use and see your doctor if you get diarrhea or develop a rash or joint pain. What happened to the side effects from prescription omeprazole? Presumably, the maker and the FDA figure that using the OTC drug for just two weeks at a time makes serious reactions unlikely. But what if you took it for longer than two weeks? Are you in danger of overdosing on these OTC meds?
How to Stay Safe:
We will discuss reading labels and finding other important sources of information about your OTC meds. We welcome your questions about these drugs and your stories about problems you may have had.
Please share your inquiries and anecdotes. You can email us: radio@peoplespharmacy.com or call 888-472-3366 between 7:00 and 7:50 am EDT on Saturday, May 18, 2024.

Show 1385: The Dangers of Overdosing on OTC Meds

This week on our nationally syndicated radio show, we examine the consequences of prescriptions for anxiety or grief. All of us, at some point in our lives, will experience some of these emotions. If we discuss them with a healthcare provider, there’s a chance we’ll end up with a prescription. When are medications helpful and when do they cause more harm than good? Are there risks in medicating normal emotions?
How Should We Understand Mental Illness?
For decades, neuroscientists have been telling us that mental illness is caused by a chemical imbalance in the brain. The logical conclusion from this premise is that emotional problems should be addressed with drugs that can alter the brain’s chemical balance. Unfortunately, however, the brain and its workings are still quite mysterious, much like a black box. The medications that may be prescribed could be thought of as a crude hammer–or, better yet, a giant experiment. This particular experiment is not well-controlled or randomized, though, and it wouldn’t pass muster as truly scientific.
Are We Medicating Normal Emotions?
When did we start thinking of everyday challenges as psychopathology? How can we change our perceptions? Both of the guests for this episode have been involved with an extraordinary documentary, Medicating Normal.
This film acknowledges that psychotropic drugs can be helpful or even lifesaving for some people. However, doctors are over-prescribing them, and the result is a public health crisis. The movie follows five individuals who experienced serious problems as a consequence of the prescription medications they were taking.
The Problems with Anti-Anxiety Drugs:
Among the most common psychotropic medications are the anti-anxiety pills called benzodiazepines. These compounds, such as alprazolam (Xanax), diazepam (Valium) or lorazepam (Ativan), can offer short-term relief from acute anxiety. Over months or years, however, the body adapts. As a result, the drug may stop working and the patient may need to take increasing amounts to get the same anti-anxiety effects. Withdrawal (a phenomenon doctors may call “discontinuation syndrome”) can sometimes result in anxiety symptoms far more severe than the original problem.
What Are the Alternatives to Medicating Normal Emotions?
Psychiatrists actually have a lot of other options besides a prescription. Cognitive behavioral therapy, exercise, or other forms of therapy aimed at changing behavior can be effective, but they require time and repetition, and thus patience. Healthcare reimbursement incentives encourage prescribing medications rather than supporting behavior change. In addition, medical students may not learn much about these alternative approaches. Medical education on discontinuing psychotropic medicines has been especially sparse. Consequently, many doctors may not feel well-equipped to help a patient get off one of these medicines.
This Week’s Guests:
Anna Lembke, MD, is the medical director of Stanford Addiction Medicine, program director for the Stanford Addiction Medicine Fellowship, and chief of the Stanford Addiction Medicine Dual Diagnosis Clinic. She is the recipient of numerous awards for outstanding research in mental illness, for excellence in teaching, and for clinical innovation in treatment. A clinician scholar, she has published more than a hundred peer-reviewed papers, book chapters, and commentaries in prestigious outlets such as The New England Journal of Medicine and JAMA.
She sits on the board of several state and national addiction-focused organizations, has testified before various committees in the United States House of Representatives and Senate, keeps an active speaking calendar, and maintains a thriving clinical practice. Dr. Lembke is the author of Drug Dealer, MD: How Doctors Were Duped, Patients Got Hooked, and Why It’s So Hard to Stop and Dopamine Nation: Finding Balance in the Age of Indulgence. Her website is https://profiles.stanford.edu/anna-lembke The photograph is of Dr. Lembke.
Nicole Lamberson is a physician assistant who took Xanax for work-related stress. Over the course of five years, she developed many classic symptoms of benzodiazepine tolerance withdrawal. Now, years after stopping the medicine, she still has some residual symptoms.
Nicole co-founded The Withdrawal Project and does marketing, distribution and outreach for Medicating Normal-The Film. She also serves on the Medical Advisory Board of Benzodiazepine Information Coalition.
