 (from 1997 through May 15, 2012)

by Duane Graveline, M.D.,  MPH

FDA has opened the shelves of MedWatch to those of us wishing to review for ourselves the status of statin adverse drug reports (ADRs). This has been all the more imperative since FDA has been extremely reluctant to report side effect data on the statin class of drugs.

I was last able to access MedWatch data in 2006. Following that, in the beginning of 2007, my access to MedWatch data was denied despite legal pressure from my lawyers. Even in 2006 the process had not been easy, for it meant I had to tackle the immense challenge of reviewing manually some 64,000 Lipitor ADRs using the "find" mechanism on my PC. This was necessary, I was told, since the appropriate software for reading MedWatch data was available only to FDA and drug company officials. The rest of us had to be content with the time-honored and accurate but painfully slow process of counting each case one by one using the search mechanism on our PC. 

What prompted me to do this personal search of what most would agree is FDA's business is the almost total lack of awareness of most doctors of statin-associated cognitive dysfunction, emotional and behavioral disorders and cases of disabling neuromuscular degeneration. Clearly our doctors have not been informed about most of these reactions, yet I know from the 20,000 emails I have received through my website (www.spacedoc.com) that many thousands of MedWatch reports have been submitted. In many cases I have been instrumental in helping distraught victims make their FDA report. What is wrong with our ADR reporting system, I wondered? I used the Lipitor data for this report. It is important to remember that all statins are reductase inhibitors blocking a single reductase step in the synthesis of cholesterol, so what is true for one is generally true for all statins. The only real variable is strength.

Because of my personal cognitive experience with this drug, transient global amnesia (TGA) was the first search term I entered. TGA is the abrupt (in seconds) loss of the ability to formulate new memory, usually associated with retrograde memory loss that extends weeks, months, years, or even decades into the past. Along with memory goes any flight training you might have received. You may no longer recognize the cockpit! I lost my entire medical training for a bizarre 12 hours when I believed myself to be 13 years old.

Not unexpectedly, out popped 1,302 case reports for TGA in the MedWatch files. Adding the search term "memory impairment" yielded me another 663 cases. This total of 1,965 reports of serious cognitive dysfunction associated with the use of Lipitor seemed to fit quite well with the total numbers of such reports I now have recorded in my repository. I have generally recommended that victims do online MedWatch reporting and had helped more than a few to do just that. 

A word of caution concerning gross under-reporting deserves to be mentioned here. First of all, anyone experienced with the operation of such non-mandatory reporting systems as MedWatch fully realize that they are lucky if one percent of the actual events get reported. So for every 100 cases of memory loss only 1 or 2 will ever be reported. That is the nature of self-reporting systems. Additionally, only the more severe forms of cognitive dysfunction get reported - the transient global amnesia and severe memory loss. More minor forms of cognitive loss such as confusion, disorientation or unusual forgetfulness are never included, so we should not expect to find them in the database.      Then we have the category of short-term cognitive loss with durations measured in seconds and minutes. By their very nature these will rarely be recognized even by the victim, and yet they might be so critical to a pilot, the crew and passengers. The passage of time is too short for recognition, yet special studies have revealed just how common these brief lapses are.

Despite the fact that in February, 2012, FDA announced cognitive dysfunction as a major side effect of statin drugs for the first time, the agency immensely under-played its seriousness. At no time did the report even mention transient global amnesia, although the past decade has seen an epidemic of this once rare condition. The inability to formulate new memory is bad enough, but for pilots the retrograde loss is especially serious, because along with decades of past memories whatever training you might have had then disappears. FDA focused instead on the possibility that periods of confusion and disorientation might occur. The implication was that these usually were mild and passed with no complications. Never a word was said about the possibility of a military or civilian commercial pilot suddenly encountering transient global amnesia, especially in a single pilot aircraft. One does not have to be a pilot to be concerned about this - anyone whose occupation requires 24/7 vigilance should be concerned. These could include a school bus driver, heavy equipment operator or even, hopefully not, our Chief of State.

 Applying additional cognitive search terms gave me 222 reports of "dementia," 523 case reports of "disorientation" and 602 reports of  "confusional state."

 I next searched among words that might reflect the curious effects of statin drugs on emotion and behavior now being reported. I found 347 reports using the search terms "aggressiveness," "paranoia" and "irritability" commonly reported in statin users. Use of the search term "depression" yielded 1,142 reports, of which 118 expressed "suicidal ideation." 

Since it also was in February, 2012, that FDA first mentioned the persistent seriousness of rhabdomyolysis, the next search term I entered was rhabdomyolysis, an especially serious form of muscle damage with a fatality rate of 10%. You may recall that it was rhabdomyolysis that led to the Baycol withdrawal from the market. Some 60 deaths in the year 2004 made it untenable for Bayer to continue selling Baycol. Death in these cases is due to the blockage of renal tubules by the muscle cell fragments from ruptured muscle cell membranes and been carried to the kidney by the circulation.

I counted 2,731 MedWatch reports of rhabdomyolysis. With the case fatality rate being 10%, the use of Lipitor has presumably resulted in 273 deaths up to now. Removing Baycol from the market in 2004 did not even slow down the loss of lives from rhabdomyolysis. Lipitor quickly took up the slack and similar rhabdomyolysis death rates are occurring from Zocor, Crestor and the others. Each year Lipitor accounts for slightly more than 20 deaths from this cause.  Applying additional search terms bearing on the muscular system, I found 1325 reports of "myalgia" and 494 reports of "musculoskeletal stiffness".

Applying the search term "renal failure" gave me 2,240 responses, comparing favorably with the 2731 MedWatch reports of rhabdomyolysis cases, knowing that many, if not most, of these would be accompanied by varying degrees of renal involvement. 

My response to use of the search term "neuropathy" was 1,294 reports to MedWatch. It should be mentioned that almost all of these peripheral neuropathy reports have proven to be very resistant to traditional treatment and now deserve to be called permanent. Using the term "Guillain-Barre syndrome" gave 98 reports, and prompted by hundreds of case reports I have received complaining of leg and arm pain, the search term "pain in extremity" gave 3,498 reports. This figure better reflects the statin neuropathy load.

Next I put in the search term, "hepatitis." Before I tell you the number, I first must qualify it by warning you that there are many different kinds of hepatitis. There is hepatitis A, B, C, cholestatic, autoimmune, fulminating, acute, chronic and viral, including cytomegalovirus. All of these terms are used in this compilation of Lipitor damage reports. However, the overwhelming majority of these reports said simply, "hepatitis" with no qualifier. Since hepatitis always has been a concern from statin use, you must make up your own mind in interpreting the 2,102 total cases that resulted. When I realized that "liver function abnormalities" also was being used in the MedWatch diagnosis list, I used it as a search term, reporting 842 liver function abnormalities in addition to my 2,102 hepatitis cases for a grand total of 2,944.

Since Ralph Edwards of the World Health Organization detected the unexpected association of ALS with statin use by using the Vigibase data, my next investigation of Lipitor MedWatch data was for search terms that might give a measure of ALS occurrence. "Unusual weakness" turned up 2,516 case reports, "balance disorders" gave 596 responses and  "coordination abnormalities" gave 195 responses. Since I have this condition, I can speak with authority on the subject of balance disorders. A kindly neighbor lady was so concerned on seeing me walk by her home she offered to drive me the rest of the way. Until that moment I was unaware of the effect of my walking on the public eye. Clearly this good Samaritan sensed me as disabled. My transition to walker took place the following day.

The Peoples Pharmacy website carries an unexpected gold mine of ALS incidence data in the following link http://www.peoplespharmacy.com/2009/07/31/statins-and-als/  Please check out this resource. Joe Graedon started this link in 2007. In it he has invited anyone struck down by statins with symptoms suggestive of ALS (Lou Gehrig's Disease) to comment on their status for the benefit of others. The last time I dug for gold here I was quite certain I had found at least 300 solid cases of ALS with hundreds of others who still might go in that direction since, as many of you understand, it sometimes takes years for ALS to unmask itself. There is no solid test.

Relevant to diabetes, it is now generally accepted that the incidence rate of new diabetes in statin users is close to 12% - an amazing user penalty for a medicine that is supposed to diminish the risk of cardiovascular disease! I used the search term "pancreatitis" to see how much of this diabetes might reflect organ damage. I found 604 reports of pancreatitis.

 I next tried the search term "cardiac failure" and turned up 720 reports. CoQ10 inhibition is felt to be the major contributor to this condition. My next search was "myocardial infarction" out of curiosity as to how many might there be in a group already on Lipitor. The figure was 2,520 - another attention getter - especially when I got 610 additional reports using the search term "coronary artery occlusion." With a total of 3,030 cardiac events in a group already on statins, I wonder just how much protection is being offered. Use of the search term "cerebrovascular accident" (stroke) yielded 1,562 reports, with another 159 inferred by the use of the search term "aphasia."

FDA has a first rate monitoring system but it is grossly deficient for reporting findings back to the medical community. The average primary care physician in our country today, knowing that only a minority of patient problems get reported to FDA, would be startled to see these figures, especially the ones for cognitive dysfunction, neuropathy, rhabdomyolysis, depression, neuropathy and hepatitis. These are the people who write prescriptions for statin use. 

From my 23 years of experience as a primary care doctor, I would say that any doctor attempting to practice medicine without full information on adverse reactions is liable for malpractice. Only with this information can proper, informed judgments for treatment plans be made. It pains me to see my colleagues being maneuvered into this position.

I have personally experienced problems with Lipitor and my muscles. I was taken off of Lipitor by my doctor and put on Lipofen. I appreciate the article above as it is informative and we all need to better understand the potential risks of the statin drugs.

I have personally experienced problems with Lipitor and muscle weakness and many of the problems that you mentioned in this article. I was taken off after complaining about the muscle weakness. Although I was unaware that it could of been Lipitor, I now know that it was. I studied more about the statin drugs. And many of the problems mentioned in this article I haven't associated to Lipitor until now. But most of it makes sense to me now after reading your article. Thank-you.

Using the FDA MedWatch database comes with a big caveat, these are only reports and represent at best an association but NOT a judgement of causality. The reports are not screened by FDA before entering into the database. The same reaction is sometimes reported by different reporters, ie, patient, doctor, lawyer, drug company and this is not screened out before entering into the database thus possibly inflating the numbers.

The purpose of reporting and cataloging the adverse reactions is to generate SIGNALS, ie, is there something new being reported or is there an increased frequency of reporting known adverse reactions or is there a more serious outcome now being reported for a known reaction. These signals must be followed up with a more in depth review of each individual report before a causal link can be established.

This requires if at all possible contact with the prescribing doctor to obtain the patient's history, diagnosis, concomitant medications and outcome for the reported reaction. Often the drug company will have already initiated this in depth review and provide FDA with pertinent follow-up information. In some cases this review will lead to further clinical or epidemiological studies to determine possible causality.

Is it possible that the avalanche of serious ailments, like diabetes and renal failure, has more to with drug side affects than natural disease processes? Has the purported benefit of statins been grossly overstated, and the numerous serious side affects grossly understated?

What would happen if statins were removed from the market? Perhaps some blip in death rates somewhere, but would there be better quality of life for millions?

I quit Lipitor after Peoples' Pharmacy alert regarding the jitters in users. I had experienced jitters seemingly naturally during my husband's long illness and death. two years later jitters continued.

I remembered that years earlier I had experienced severe muscle pain and had taken a "vacation" from Lipitor and the pain stopped.

My doctor insisted that Lipitor saved lives and urged me to resume its its use even though my cholestorol was in the old normal range- about 120.

One year ago I again quit Lipitor. The jitters are gone and my blood work is fine. Now if I could get my memory back I would rejoice!

This was very interesting. I've read about Dr Graveline's experiences before but it's good to refresh one's memory. My husband had been on Lipitor 10mg for several years until a little over 4 years ago when our insurance changed and we'd have to pay a lot more for brand name so he changed to Zocor generic simvastatin 20mg even though it hadn't worked to lower the cholesterol when he started statins. Doctor said try it, take his Norvasc generic & simvastatin together. For a few years he's had a lot of pain in his arms we thought due to a couple of falls. Then the first of the month I happened to check at drugs.com on the interactions and found it has a major interaction due to Norvasc amlodipine being a CYP3A4 inhibitor making the simvastatin stronger. He's quit it and going back to Lipitor generic but I wonder if it's going to be a problem too??

Just tonight I did a search on cinnamon and found one study from 2010 that says cinnamon is a strong inhibitor of CYP3A4, we've been taking it for his blood sugar and my cholesterol. I already knew about grapefruit, peppermint oil, possibly pom juice but cinnamon! Oh, forgot black pepper extract Piperine which is being put in some supplements to enhance their bioavailability. http://www.ncbi.nlm.nih.gov/pubmed/21139236

Oh and his arms don't hurt nearly so much. I guess the cinnamon is just for me now because I don't take anything but thyroid meds and that doesn't use those enzymes to metabolize. I thought this info would be a good head's up to someone.

Linda Wertheimer interview with Dr Steven Nissen 7/2713 NPR @1:00 pm seemed such a soft balled commercial for statin use. It's a shame his Avandia "giant slayer" reputation wasn't challenged to reveal the truth about statins very real side effects and despite their miraculous ability to lower cholesterol, have done nothing to improve initial cardiovascular outcomes. I know I'm way out of my depth, but would have expected more from such a caliber journalist as Linda. Dr Nissan said statins reduce heart attacks by 25-30%. Studies that aren't tainted by big Pharma question this assertion. As I said, I'm confused, and mistrustful. Thanks Chris

People's Primacy response: We too were disappointed that Dr. Nissen was not challenged on the statements, not even on his enthusiasm for drug to raise HDL. So far, none of the drugs that have been tested for this purpose have been proven useful.

Dr. Nissen is always a proponent of statins, but we think he offered us a somewhat more nuanced view in this interview from fall of last year:
http://www.peoplespharmacy.com/2012/10/20/877-keeping-your-heart-healthy/

Dr. Graveline is to be commended for his laborious attempt to call attention to the connection between statins and adverse effects experienced by too many people. I suspect the FDA numbers actually are under reported and contributed mostly by patients. I have made two such reports myself, and it takes time to complete which time I do not believe many health care providers can afford. I gave this very important article to my husband's young cardiologist last week. I just hope he will read it, because he has high regards for lipitor.

How scary that "Just last week, the FDA actually proposed loosening the already-lax requirements for drug approval by allowing many new drugs to gain market approval without safety testing or clinical trials. If the FDA and so-called medical experts perceive a new drug as being potentially beneficial, the agency wants to be able to simply approve it now and ask questions later (http://www.reuters.com)." We now have to believe that the FDA has beome more of a lap dog for Big Pharma than a watch dog to protect us!

The US and New Zealand are the only two countries that allow TV commercials for prescription drugs. Pfizer hit the jackpot with the introduction of it's golden calf lipitor when it went into overdrive with "direct-to-consumer advertising. Its campaign aimed at conveying two simple messages. The first: You don't have to be visibly unhealthy to have dangerously high cholesterol. The second: "Know your number"--that is, the level of bad [LDL] cholesterol in your blood. A reading above 160 milligrams per deciliter of blood is considered risky, while a reading below 100 is optimal." (Fortune Magazine." 1/20/03).

Further, drug companies use mostly men in their trials to the exclusion of women and the elderly. The real drug trials begin after a drug is approved (and now more than ever with the new FDA plans referenced above), using the the general public as Guinea pigs. Doctors then are lured into the standard basis of care because they follow the inaccurate guidelines without question. They don't want to link any drug association with adverse effects because they lose the tools in their bags to lower cholesterol numbers as any good doctor would be expected to do. Too often, however, the risks simply outweigh the benefits.

In 2004, eight of the nine people making the last cholesterol levels revision, with no trials as a basis, had ties with the pharmaceutical industry. Every time these levels are lowered, millions more unsuspecting victims are snared into Big Pharma nets to their monetary advantage.

Statins will lower inflammation and cholesterol as evidenced by 50% of people with normal cholesterol levels suffering from heart attacks, but statins obviously do not prevent heart disease and strokes as cardiovascular diseases still are the leading cause of deaths in the US.

Statins originally were prescribed for secondary prevention of another heart attack or stroke, but today a majority of people take drugs for primary prevention if they have certain risk factors of heart disease even though they otherwise may be healthy.

What an incredible article... I'd like to know why MedWatch is not advertised on every pill bottle... I'm sure at least more than half of consumers are unaware that they can report adverse drug side effects. Would love to see a hotline number on all drug labels (OTC and prescription,) in this country. Then you'd see big Pharma running scared... naturally, giving ALL consumers that info is not going to happen. Health Consumers are on their own, with the exception of the Graedons and other courageous doctors, pharmacists, researchers, journalists and watch-groups. Thank god for the warriors who go to bat for the consumers! Professionals like the Graedons and Dr. Graveline make me believe there are still good, courageous people in this world who will fight for what is right... Would love to hear more from Dr. Graveline.

People's Pharmacy response: Keep watching our site, and you will see more from him soon.

Having practiced in the pre and post stain eras. I have seen a gratifying reduction of TGA, acute coronary events, strokes and vascular dementia.

A retiring university cardiothoracic surgeon noted that the most remarkable change in his practice was the decreased need for second revascularizations with the era of statin use.

So why wait for a preventable vascular event or preventable invasive cardiovascular intervention, before starting a statin. Risk assessment has greatly improved, so that we can gauge if someone has a risk equivalent of a post coronary patient. Coronary disease should not call for a surgical remedy. It just means we missed an opportunity for prevention. Comprehensive preventive programs are needed, since statins can carry only 1/3 of the load.

Of course the clinical trial do not show all these benefits. They accrue over decades. Once clinical benefit is confirmed, it is unethical to continue studies and deny patients effective therapy.

I want to come off statins. In 2009 I mentioned to my physician that I was experiencing memory and muscle issues. He shrugged if off. I stopped taking lipitor for a while. My numbers went back up and I got back on the generic brand. Can someone recommend something other than a statin for cholesterol.

My father recently suffered a stroke. He is in his 90s and had no short-term memory problems before. He had complained to me of muscle aches several years ago when his doctor recommended that he take simvastatin. So he stopped taking it, but after the stroke his doctor insisted that he resume use of simvastatin.

Well, now his muscles are not responding well to the therapy and he's beginning to develop short-term memory loss as well as full-blown diabetes. How interesting ... my family is being told that "this happens to stroke patients", but I have to wonder if these symptoms could be due to statin use??? After reading the above article, I'm quite suspicious.

I cannot help but wonder if some of the statin side effect are increased by a possible B12 deficiency?

I don't think even Dr. Graveline has looked into this possibility since most physicians don't think B12 deficiency is that important or prevalent.

B12 supplementation has such a low level of problems, it might not hurt to add 1,000 mcg of methylcobalamin to your daily routine.
