Some Statins Linked to Peripheral Neuropathy: Is Crestor among Them?

. By
Washington, DCJoe and Terry Graedon, both doctors, are also authors and maintain a popular syndicated column known as The People’s Pharmacy. Readers write in with their ailments with the Graedons offering some sage advice. Recently, a patient on one popular statin for several years followed by Crestor for the last year had some questions about side effects and wondered if they were, indeed, Crestor issues.

Specifically, the patient had taken atorvastatin for six years, followed by rosuvastatin (Crestor) for a year. “I developed severe pain in my leg muscles, primarily my calves, which led me to discontinue the drug,” writes the contributor to The People’s Pharmacy, “but the pain has remained.

“I have been diagnosed with probable nerve damage. The neurologist acknowledged that they are seeing side effects after years of statin use by patients.” The author of the submission further noted that pain management in this case involves strong opioids such as fentanyl, administered with the help of a pain specialist.

In other words, pretty serious stuff.

In her reply, Terry Graedon noted a widespread belief by doctors that statin use is critical for heart health in many patients, and especially those with pre-existing cardiovascular issues, with clear signs of heart disease or having already suffered a heart attack.

But here’s a pearl of interest to anyone who has experienced Crestor side effects or adverse reactions following the use of any statin: “Clinical studies designed to get [US Food and Drug Administration] drug approval for statins did not reveal signs of nerve damage, so such symptoms are often discounted as not drug-related.” According to Graedon, the World Health Organization (WHO) in 2005 noted in a wide-ranging report that “statin-associated peripheral neuropathy may persist for months or years after withdrawal of the statin.”

Sure enough, there it is, in the WHO Drug Information report, Volume 19, No. 2, 2005. Scrolling down to the end of Page 115 presents a revealing headline originating from Australia: ‘Statins and peripheral neuropathy.’

“The Adverse Drug Reactions Advisory Committee (ADRAC) has received 281 reports of peripheral neuropathy or symptoms consistent with this diagnosis attributed to statins…and first highlighted this association in 1993. Thirteen of the 281 cases were confirmed by nerve conduction studies. Both sensory and mixed sensorimotor peripheral neuropathies were reported. The time to onset ranged from one dose to 4.5 years.”

The report noted that peripheral neuropathy is indeed rare, and also noted that many patients with neuropathy have other medical conditions that predispose them to the malady, including diabetes (Crestor diabetes is one side effect of rosuvastatin and other statins that has little to do with neuropathy), together with chronic renal failure.

The most unsettling aspect of the report, as noted above, is that about half of the cases identified in the WHO 2005 report recovered from their neuropathy when the statin was stopped. “Statin-associated peripheral neuropathy may persist for months or years after withdrawal of the statin.”

It’s important to note that none of the 281 cases identified in the ADRAC report involved rosuvastatin (Crestor) specifically. Statins involved were identified as simvastatin, atorvastatin, pravastatin and fluvastatin. Thus, Crestor is not implicated in any way, in this study.

The report does, however, serve to caution anyone about to go on or currently taking a statin for cholesterol. Specifically, Crestor side effects include, in rare cases, Crestor rhabdomylosis - a condition where muscle tissue is broken down and absorbed by the bloodstream with often grievous results.

Statins have long been prescribed to patients with a history of heart disease, heart attack or other cardiovascular issues - or at high risk. However, in recent years doctors have been prescribing statins as preventative therapy for Americans over 50 when no risk factors are present.

It's all fodder for a Crestor lawsuit, should a patient be experiencing pain while either on Crestor or post-Crestor.

At the age of 50, I started taking Simvastatin in 2006 and about 6 months later I developed cramps in my calfs while jogging. I tried to ignore it, but the pain developed progressively until I collapsed onto the floor at work one day. I blamed the statin and discontinued. After nerve conduction tests excluded neuropathy, the neurologist diagnosed restless legs syndrome. I was in terrible pain for years but it eventually subsided and now it only really bothers me at night or if I have to sit for long periods in a chair (I like to keep my legs raised and work from a laptop instead of a desktop).

I have tried to go back on various statins several times but they seem to aggravate the RLS and I stop after about a week to ten days. The problem in attributing a cause and effect relationship is that RLS tends to wax and wane of its own accord and many drugs and even foods are supposed to accentuate it.

Although I would like to gain any benefit I can from statin (a heart attack is no picknick), a slight increase in my symptoms after starting the drug strikes fear into me and I stop.

Its a difficult thing to judge.

I began taking Crestor December 2011. My blood glucose was 104. I was very pleased that my cholesterol levels went down, but 4 months later started to experience the horrible burning pain of peripheral neuropathy. I researched over and over online trying to find what was causing it. It continued getting worse, and at my lab tests of 8/24/12, my sugar levels had shot up to 119. I still kept searching online for what could be causing the neuropathy, and the only articles I found pointed to diabetes. Just prior to that my PA said we needed to start thinking about diabetic control meds. I asked him to hold off and it was after that I found several articles indicating that Crestor had caused diabetes in many people and there were various lawsuits for people who had become diabetic after taking statins, so in May 2013, I stopped taking Crestor. My sugar levels 3 months later were 122. I can only imagine how much higher they had gotten before I took myself off Crestor. My sugar levels continued going down to 99-101, and my A1C dropped from almost 6 to 5 after I stopped taking Crestor.
However, 4 years later, I'm still suffering from the terribly painful, sleep robbing neuropathy. If I had continued taking Crestor, there is no doubt in my mind, I would have developed full blown diabetes. My sugar and A1C levels have remained down, but the neuropathy has continued. I KNOW it was the Crestor that caused it. I called one of the lawsuits about my situation, but the agent I spoke with said they were only interested in those who were diagnosed as diabetic due to the Crestor. As I said, if I had continued with Crestor, I know I would now be diabetic. I took myself off of it, my sugar levels went down, but the neuropathy is the horrible side effect it looks like I will have for the rest of my life.

I started Crestor in September of 2013. About 9 months ago I began suffering foot pain in the balls of both feet. Unexplainable. I started to wonder if I was diabetic. Running this thought down on the web it didn't seem to align with my symptoms. I eventually began reading about the medications I am on. I believe Crestor is the culprit. I stopped taking it with my doctor's permission for one month. The pain has not stopped but slightly diminished. Having just read that it could take years is scary. What should I do now?
I am worried about taking care of my heart. The foot pain is incredible.

Just finding out that the neuropathy in both feet and spreading up my legs, the painful night muscle spasms and numbness in both hands is not related to my spinal stenosis. My then doctor started me on Lipitor in the late 1990's ... didn't tell me what my cholesterol numbers were just that I needed to take statins. Took Lipitor until about 15 years ago when the doctor prescribed Pravastatin 40 mg - which I have been on until now. So what do I do now? Will the neuropathy get better if I stop Pravastatin?

The excellent Australian report, picked up by WHO, came out before Rosuvastatin was available in Australia.

I have been off my dosage of 10ml Crestor for almost a year now and still I have pain in both shoulders, arms and calf muscles. Ck level normal, shoulder x rays and ultrasound tests normal. I have seen about 10 doctors/specialists and still not a diagnosis because none of them know any details about Statin side affects. Whilst I was on the 10ml dose my heart rate went down to 25bpm and I had no warning or ill feeling. At 22bpm I was told the heart would just stop. I immediately had to go into surgery to have a pacemaker inserted. In the earlier notifications by the manufacturer of Crestor it lists bradycardia as a side effect. But does anyone out in the real world know that??
I was only on the 10ml dose for about 18 months, prior to that I had been on a dose of 5ml Crestor for about 7 years. And in that time I lost a kidney to cancer. Cancer is also listed a a side effect.
On the net under Scholarly research papers one can find hundreds if not thousands of reports by doctors and medical specialists including professors highlighting the side effects and damage caused by statins, but I can't find a knowledgeable doctor in Australia.

I have researched and have come to the conclusion that I have Peripheral Neuropathy. I went to doctors last year and both family and heart doc said that it wasn't due to Crestor. I am on Crestor 10mg for the past two years. My symptoms just popped up about 6 months ago. They both ran blood work and everything is fine. They said usually its a back issue that brings this on. I truly believe they are wrong and especially after reading this. I plan on calling him up and asking to be taken off crestor. I was only put on it as a preventative measure. damn-it I'm pissed. They should know this stuff.

I was started on Antara in 2004 when it was suspected that I had Peripheral Neuropathy. After starting Antara, I suffered immediate painful calves and legs. When I complained, my physician put me on Simvastatin. I felt even worse. I had no idea where this pain was coming from. Doctors told me I had a "back problem". I had NEVER consulted a GP, Orthopedic or Neurologist for symptoms associated with back or leg pain. When I tried to explain I had never had this problem, I was dismissed. I suffered from 2004 to 2013. I finally was advised by a Pharmacist that these symptoms could be related to any cholesterol lowering drug. During June 2012 to June 2013, I had chronic kidney infections and problems never experienced in my life up to that time. It felt as though my kidneys were shutting down. After a hospitalization for dehydration, my cpk levels were 6 times normal and I could not urinate but was very swollen. I stayed overnight in the hospital, was hydrated and was released early the next morning. I have not taken statins since. I researched the topic, found that statins could be the cause of all my symptoms and stopped them. To this day, I still have terrible leg pain with documented peripheral neuropathy and sciatica along with memory loss both short term and long term. I am trying to exercise every other day to regain muscle loss and endurance. However, it is seriously an uphill battle. I wish I had never taken these poisons.
