Zocor Rhabdomyolysis Muscle Injury Warning Issued by FDA

High doses of the cholesterol-fighting drug Zocor can increase the risk of rhabdomyolysis, a serious and potentially fatal muscle disease, according to federal regulators.  

The FDA released a Zocor rhabdomyolysis warning on March 19, as part of an ongoing investigation into the side effects of Zocor and other cholesterol medications that belong to a family of drugs known as statins. All statins have been found to carry a risk of muscle injury, known as myopathy, and rhabdomyolysis is the most severe form, potentially causing severe kidney damage, kidney failure and death.

All statins currently contain a warning that myopathy and rhabdomyolysis are rare possible side effects, however this is the first time the FDA has warned that the conditions may be dose specific.

Statins are the best-selling drugs in the United States, with $14.5 billion in combined sales in 2008. They use the liver to block the body’s creation of cholesterol, which is a key contributor to coronary artery disease. Statin is used in a number of other popular cholesterol controlling drugs, including Crestor, Lipitor, Mevacor, Lescol and Pravachol.

Zocor (simvastatin) is a synthetic statin developed by Merck & Co., which is now available as a generic. Before patent protections expired in 2005, it was Merck’s best-selling drug and the second best selling cholesterol lowering drug in the world, bringing in $4.3 billion in 2005.

The FDA’s drug safety communication warns that data from a large clinical trial indicates that the highest approved doses of Zocor, 80 mg, carry an increased risk of muscle injury over lower doses. Zocor rhabdomyolysis causes muscle fibers to begin to break down, releasing a protein called myoglobin, which can damage the kidneys as they attempt to filter it out of the bloodstream.

Zocor is also used in the combination cholesterol lowering drugs Vytorin (Exetimibe/simvastatin) and Simcor (Niaspan/simvastatin). Vytorin is produced and marketed as part of a joint venture between Merck & Co. and Schering-Plough, while Simcor is manufactured by Abbot Laboratories.

Symptoms of rhabdomyolysis include muscle cramps, tenderness, stiffness, pain or spasms. The illness is usually reported in patients over 65 years of age or those who have renal impairment or uncontrolled hypothyroidism.

The connection between Zocor, other statins and myopathy has been under investigation by FDA for some time. In August 2008, the FDA warned healthcare professionals not to administer more than 20 mg/day of simvastatin to patients receiving heart drugs containing amiodarune, such as Cordarone and Pacerone.

In addition, researchers from Europe warned last month that statins can increase the risk of diabetes. University of Glasgow scientists analyzed the results of 13 different studies into the side effects of statins and found that people using the cholesterol drugs faced a 9% increased risk of being diagnosed with type 2 diabetes.

The FDA recommended that patients not stop taking Zocor unless told to by their health care professional. They should contact their doctor if they experience muscle pain, tenderness or weakness, dark or red-colored urine or unexplained tiredness.

I very rarely go out. I'm unsociable. I have pins and needles constantly, the worlds worse tinnitus. I rarely sleep, my existing renal failure problems ( because despite constant trips to my gp no one even did a blood pressure test!) my rotor cuffs on both sides have completely disapeared!! I have had my biceps muscle on one side attached to my shoulder and I really need total reverse shoulder replacements that my consultant is trying to put back till I'm 60! (I'm only 55 now!) I have worsening irritable bowel syndrome. I have difficulties swallowing. My neck I'd in constant agony and the glands behind my ears are really painful and oftan so are the glands in my neck!! My joints are excruciatingly painful, my knees are so bad I can't walk and stairs are impossible! I now have a cough which is especially worrying as I am also on Myfortic. to try and preserve what's left of my renal function and lower my sky high protinuria. I suffer stabbing shooting pains and sciatica like pain down my leg. My back is screaming agony and my arthritis is worse than ever and declining a the time! I'm now awaiting an operation as they thought I had AVN in my legs (I lost my right hip to this due to steroids to slow my renal failure!) I have had MRI's of my back and legs and a ridioactive dye test! No one will give me the results if this!) I was told I have several anomalies! I am now awaiting an operation on both long bones of the right leg first and they are carrying out biopsies and I've been told that they can't rule out cancer!!! I've been on the net as I now suffer memory loss, fog. Mix up words, lose track of what I'm saying half way through a sentence! And, use inappropriate words! I get numb and can't feel my hands or feet, I have skin conditions, vascular insufficiency, nausea, dizziness, lose my balance and have significant deterioration of my vision!! There are probably things I have missed! I can't breath as I type this! It's frightening!! I only found people's comments on the net by chance and as I have been on 80mg of simvastatin for 4 years and have complained of symptoms to various GP's and consultants no one has helped me! I'm having nightmares and I'm living a nightmare! My problems are horrific!! I wish I had never ever even taken ONE of these dangerous, dangerous drugs! I am planning on seeking compensation.

I was finally diagnosed with a myopathy but being diagnosed doesn't help since they don't know what to do to make it better. I also take pain meds, but they only help diminish the pain they do not remove it. I really wish they could develope something that could reverse the symptoms.

I was sent for an MRI of the shoulder, nothing. then X-Rays of the shoulder still nothing. and then an MRI of the spine, 3 bulging disc. However they are not the problem. After spending thousands of dollars in medical fees, my Chiropractor thought it maybe the statin drug and suggested that I talk to my Dr and pharmacist. The pharmacist said yes it is probably is the statin, and my Dr took me off of it a week ago. The pain is somewhat better, but the mobility is about the same. Does anybody know of any lawsuits or if I will ever get the mobility back? My life has changed over this and I would HIGHLY recommend they take this drug off the shelf.

    I have been taken Simvastatin for more than a year. I recently went to the doctor for pain in my lower leg. I now have muscle pain throughout my body. I work out at least five time a week and was never sore before.

Approximately three months ago, my shoulders began aching at night so bad that it would wake me up. I went to the doctor and asked him for arthritis medication thinking that was the problem. Well, it wasn't! The pain started to get worse daily. The pain went from my shoulders to my elbows. The only way I could explain the feeling was that my muscles felt like they were turning to stone, they wouldn't relax. It didn't feel like a charlie horse, more like a throbing / stabbing ache. I didn't want to go to sleep at night because I knew that the pain was going to be even worse in the middle of the night. I felt like I had a toothache in both arms! Putting on my bra was excruciating! I also had about 5 episodes where it felt like someone punched me so hard in my chest that it took my breath away. It was a very quick sharp pain right between my breast...like no other feeling I have ever had. I went to the doctor again five days ago and told him all of this, and immediately he told me to stop taking the Zocor. I asked him for some Percocet so I could get some sleep at night, which has helped. I pray that I don't have long term damage to my muscles.

After about six week later I had diverticultitis taken off the naprosyn. My DR took blood that was positive for high lever of enzyne in my biood,triglycerides was over 1000. Zocor had been recall for 80mg but can't find a lawyer willing to take on cases taking 40mg even thought I had bad side effects. Anyone taking 40mg of zocor and had bad side affect should report to FDA.

The following day, as I am writing this an otherwise healthy 53 year old (only problem is high cholesterol) is being wheeled into surgery for a pacemaker. The lower chambers of his heart are suddenly not functioning properly. We are wondering if the recent increase in dosage has to do with his heart suddenly becoming weak? I have read a lot of information with muscle myopathy, mostly with the legs. The heart is a major muscle, is there any chance Zocor was the culprit that lead to his current heart problems? Has anyone else developed heart problems while on this drug?

Then over time my legs started to feel like they were being squeezed. I wasn't able to sleep at night. Then my left knee starting to get a sharp pain in it so bad I couldn't stand it, especially at night when I went to bed. That's when I went to the doctor about the pains. She took x-rays, said the x-ray showed no knee problem. She sent me to physical therapy. That didn't help. Then the pain went from my left knee to my right knee. I complained again to the doc and she gave me exercises to do. Several months after I started the simvastatin I started getting heart pluputations but several months ago they got worse and scarry. I address this with the doctor and I was put on a 24 hr heart monitor but the monitor showed no signs of any issue to worry about but the palpitations continued to happen. I decided I'd had enough of the leg aches and heart palpitations. I sought out a NMD and she started me on magnesium powder and fish oil. She didn't tell me to stop taking the simvatatin but I decided to stop the second day I started taking the magnesium and fish oil. It's been a week now and my legs and knees don't hurt as bad. I was able to go for a walk the other day I haven't been able to do that in a long time. My legs still hurt but I was able to handle it. I haven't had any heart palpitations either. I'm going to see if I can keep my cholesterol down with diet and supplements.

I tripped in an exercise class and had difficulty getting up. Thought I was just tired. Increasingly noticed extreme fatigue, extreme difficulty climbing or descending stairs, kneeling, and rising from a chair or the floor. Shortly, both knees had swelling and almost unbearable arthritic pain. Without exercise my weight went up and my leg muscles deteriorated so much that I could squeeze my leg and feel the thigh bone through the surrounding fat (no muscle tone!). Though the doctor never explicitly connected it to my troubles, I went off the medication - within five months of starting. Needed to use a cane, got steroid shots for the knees, explored many possibilities for continued exhaustion, pain, and weakness - no answers. After two and a half years of misery, two six-week sessions of physical therapy (modest improvement only), I tried water exercise therapy. Finally began to get muscle tone and balance back. No more knee trouble. Highly recommend this avenue for fellow sufferers - and the avoidance of statins for those of us who experience these side effects.

I haven't talked to my Dr about this as of yet, but have just stopped taking Zocor to see if makes a difference. The muscle pain and involuntary movements havent stopped and have become More Apparent since Stopping the 40 mg dosage.

I'm told that the bypass surgery should not have had the effect of the way I feel. Anyone willing to share would be appreciated. I'm only 57 years old, but always feel like I'm 95... Thanks for reading. I only became aware of the possible mucle effects of this drug due to an Edgar Snyder commercial.

Some nights my feet would be on fire; I put them on ice! My balane has become so impaired that I have had many falls. I am unable to walk any distance without pain. Stairs are almost impossible. I am tired all the time. I would forget things and had to place alarms on my phones and sticky notes everywhere. After I took myself off some of the the symptoms got better ---the burning feet are less frequent and the memory loss has improved. However, the muscle pain persisted and the weakness increased. I have to use a cane and had to cut back on my job duties. Those symptoms did not reverse as they were supposed to. Finally, in August 2010, blood tests showed extremely elevated muscle enzymes and my doctor diagnosed polymyositis. I had a muscle biopsy to confirm this diagnosis. The surgeon told me that there was not a lot of muscle in my thigh. The results of the biopsy do not indicate an auto-immune disorder. It appears that the polymyositis was triggered by this Simvastatin. I am now on steroids; will have new blood tests at the end of the month to check on muscle enzyme levels and then proceed to physical therapy to attempt to build back muscles.

The pain in my left shoulder is so bad I have trouble getting my arm over my head. Then the pain goes down my arm to my wrist. I told my MD and he keeps telling me I'm getting older and don't do so much hard work, have someone help me with those things. Finally at my June appointment, he made me a appointment with vascular screening. So in July I had the test. The technician that performed the test felt that it did not have to do with my vascular system, however, the doctor will look at the test to determine if that is what my problem is. I am going to my MD this Friday and he will let me know of the results. Even as I am typing this right now, I have pain in my shoulder and arm. I will talk with my MD about this drug.

He told me to continue with the medican but lucky for me I went aginst doctors orders and showed imidiate improvement. Now that Ive been off the meds my cholesterol has not been high.

Now I'm told these side effects will be permenant - burning feet, cramped muscles in my legs, knee pain, hip pain, & clicking muscles while I TRY to sleep. The symptoms like ear ringing, runny nose,fatigue & the inability to concentrate have lessened greatly though. Does anyone know of a Claaa Action Law Suit?? I'm ready. DON'T TAKE this medication if you start with symptoms or try any others. Talk to your Pharmasist

But I am seriously concern now, and have been experiencing ringing in my ears everyday and continuously even now. Usually starting in the morning and continuing all day and night, I think it stops during my sleep. Could it be from the medicine, where do I turn and what is worse, the risk from the medication or a heart attack? God Bless America.

Extreme pain in the knees, thought the joints were wore out. Was told that I was borderline diabetic and within 4 months diagnosed full Type 2 diabetes. Started experiencing problems walking and slurred speech. Dr. just told me today that all this may be Simvastatin related and immedaietly stop the drug. Doing CK test today for muscle loss. I pray this is recoverable side effect. Reading the Internet today has me fightened! Think twice before taking this drug. Why wasn't I informed of these possible side effects????

Cholesterol is produced by the liver. If you consume too much in your diet, the liver adjusts how much it makes. Seldom is too much cholesterol a function of how much you eat...unless you eat nothing but cholesterol, I suppose. And very seldom is a high cholesterol count because the liver produces too much. If you have a high cholesterol count (and that number is subject to debate), it's because some function of the body which is supposed to be using that cholesterol is failing. Shutting down a perfectly functioning organ (the liver) is not only foolish, it's dangerous, as we now see. If the doctor tells you your cholesterol is too high, make that doctor explain to you what part of your body is not functioning properly. And don't accept that it's the liver. It's probably not. Yes, a part could be diet. A good part is that the body is made to be physically used and very few people seem to get the physical activity they need. Low hormone count is another very big point. Increasing testosterone from low to mid-range can cause a decrease of 50 or more points. And makes for a much healthier and more happy lifestyle!

There has to be a 'connection' with the Zocor (or other statins) creating a form of degenerating myoitis, based upon my investigations.

After 2 months I went back to the prescribing doctor and told her of my continued pain and limited use of my left arm telling her it must have been caused by the Zocor because I didn't do anything to injure my arm in any way. She said "It was not caused by the Zocor" and sent me for physical therapy. I have been in therapy for 5 weeks now with no improvement. I am now being referred to a orthopedic doctor. The physical therapist says I have frozen shoulder, which I may have since I cannot use my left arm without pain. Any sudden moves with cause excrusiating pain and will bring me to tears. I am a 58 year old female with no prior history of aches and pains and I know Zocor has caused all this pain in my arm. I would not recommend this medication for any treatment and hopefully will be taken off the market in order to protect other patients from the pain I now have to endure.

After checking my blood work she discover that the medicine was in fact the cause of my muscle pain and extreme fatigue and headaches. After being off for a month my enzme levels are still high and still having muscle pain but much better then before. This needs to be taken off the market

Before this I had been quite healthy. After several visits to the doctor he finnally realized it must be the Zocor. I stopped taking Zocor that day. My leg improved and the pain eventually went away. I went back to work. I have a slight remnant of the damage. I go to work every day. Now I am almost 65. Getting off Zocor is the best thing I ever did. I prefer natural remedies.

My cholesterol wasn't that high, but I didn't know any better. Within a week, I knew something was wrong. I was very weak, couldn't think , no concentration. A trip to the grocery store took 4 days to recover from. This was absolutely not from the heart attack, as it was so mild, the doctor even said it could not be from the attack, but were at a loss. I wasn't able to connect it to Zocor as I had no knowledge of it. As things progressed, I got to where I couldn't make it up stairs without exteeme fatigue. I stared at the walls for days with no thought. I stayed home and didn't answer the phone because I couldn't think of words to form sentences. After about 7 months on the Zocor, I started haing pain in my legs, shortly after the doctors increasing the dosage. After all the complaining to the docs about the sideeffects a"to something", I was told, "you have to take them, it isn't the medicine, maybe you should see someone in mental health". As the pain in my feet and ankles started, it progressed up my legs. I noticed it was about 4 or 5 inches a day, until the pain was halfway up my thighs, and severe. That night, I had severe pain in my legs, tingling of the nerves in my hands, lips, tounge. At about 2 am, it was so severe, I was scared. I got on the internet and started loooking for anything I could about the meds I was on. I found a guy....Dr. Grapevine, I believe was his name. His website had an enourmaous aount of information that led me to believe it was the Zocor causing the problems. I called the pharmacy the next day and reported it, and told them I refused to take it any longer. Within 24 hours I noticed an improvemnent in my strength. It has been about 2 years now since I stopped, but I still have the tingling, significant loss of strength. I am fatigued easily, my legs hurt all the time. If I walk very long, I get the severe pain in my lower legs. I am on pain killers allthe time now to stop the tingling, which never really goes away. If I stop taking the pain killers, my toungue and lips and face, and hands all tingle like needles poking them, and my legs hurt very bad. I would suggest no one is ever put on this medicine..ever!!

Despite repeated complaints and visits to my cardiologist and local MD, it fell on me to research my high CPK and make the link. I also had a 4x bypass, and as the fatigue stayed, a des stent placed inside a "occluded" plain stent (after only 5 months). Makes me wonder if the stent placement was really needed, as the fatigue/weakness issue continued. Suggestion: sell your Merck stock.

    I am in my 60's but not 65. Every night I had very bad muscle cramps pain and tenderness from the Simvastatin. I was jumping out of the bed many times during the night. I did not take a large dose ,only 10mg. I have blamed everything but the medication for this condition. Now, I have stoped taking it and what an improvement.
