Simvastatin Muscular Weakness Causes and Reviews


Myasthenia gravis is a disease that causes weakness in your voluntary muscles. These are the muscles that you control. For example, you may have weakness in the muscles for eye movement, facial expressions, and swallowing. You can also have weakness in other muscles. This weakness gets worse with activity, and better with rest.

Myasthenia gravis is an autoimmune disease. Your body's immune system makes antibodies that block or change some of the nerve signals to your muscles. This makes your muscles weaker.

Other conditions can cause muscle weakness, so myasthenia gravis can be hard to diagnose. Tests used to make a diagnosis include blood, nerve, muscle, and imaging tests.

With treatment, the muscle weakness often gets much better. Medicines can help improve nerve-to-muscle messages and make muscles stronger. Other drugs keep your body from making so many abnormal antibodies. These medicines can have major side effects, so they should be used carefully. There are also treatments which filter abnormal antibodies from the blood or add healthy antibodies from donated blood. Sometimes, surgery to take out the thymus gland helps.

Some people with myasthenia gravis go into remission. This means that they do not have symptoms. The remission is usually temporary, but sometimes it can be permanent.

Simvastatin Muscular Weakness Reviews

I've been on a Simvastatin for 6 months. I broke out in a mysterious rash about a few weeks after I began it. I've had a rash ever since. 2 dermatologist and 1 allergist later, it is the opinion of 1 dermatologist and the allergist that my rash is resulting from the Simvastatin. My heart dr. has never seen anyone get a rash from a Simvastatin, but he is going to work with me. He wants me to be off of everything I take (vitamins also) for 6 weeks. If the rash disappears, we will begin to introduce each pill 1 week at a time. I itch everywhere. The rash is terrible. My dermatologist has me on Doxepin at night, an antihistimine in the day, and cortizone mousse. I still itch. I can't seem to find others that have experienced a rash from a Simvastatin. Please reply if you can sympathize.

I have been in Zorcor for a good 6 years with no problems (40mg). I did not have any problems until recently. I now have a number of strange complaintes. I thought it may just be part of getting older. I am having joint and muscle pain and extreme headaches that absolutely debiliatate
me. I have a rash and my throat swells at times.Until reading some of your comments, I never suspected it could be from the same med. The swellinng in the throat was the final straw. I am officially off the med. as of today, with an immediate doctor visit in the works.

Have been on Zocor for almost 10 years with no problems but 6 months ago started getting rash on my left side which seems to be less annoying with good skin lotion. I also take some vitamin pills that have 1000% niacin(for building good HDL) and Niacin is known to create rash in many people along with other side effects that are similar to Zocor. If you are taking niacine as well as Zocor I believe the combination may be the cause as I have tried stopping either and the rash dimenishes, ythough does not disappear. The reduction of fats in your blood may just be giving you abnormally dry skin resulting in the rash as it seems ceaseing either pill reduces my rash to the area around a very small mole.
