carolyn dalton,

 

Thanks for your question.   Simvastatin is a medication used in the treatment of elevated fats (lipids) in the blood.  It lowers total cholesterol, and specifically lowers "bad cholesterol" (LDL) and raises "good cholesterol" (HDL). 

 

I am inserting the side effect section for simvastatin from our website:

 

 

      Side Effects

            Stomach upset may occur. If this effect persists or worsens, notify your

            doctor or pharmacist promptly.

           

            Remember that your doctor has prescribed this medication because the

            benefit to you is greater than the risk of side effects. Many people using this

            medication do not have serious side effects.

           

            This drug may infrequently cause muscle pain, tenderness, or weakness

            (which can rarely lead to a very serious condition called rhabdomyolysis).

            Seek immediate medical attention if you develop these muscle problems 

            (especially with fever or unusual    tiredness).

           

            Tell your doctor immediately if any of these highly unlikely but very serious

            side effects occur:

  • yellowing eyes and skin
  • dark urine
  • severe fatigue
  • stomach/abdominal pain
  • persistent nausea
  • change in the amount of urine

            A serious allergic reaction to this drug is unlikely, but seek immediate medical

            attention if it occurs. Symptoms of a serious allergic reaction include:

  • rash
  • itching
  • swelling
  • dizziness
  • trouble breathing

            If you notice other effects not listed above, contact your doctor or

            pharmacist.

 

 

Our website has much more information about simvastatin.  Just go to the search portion of this page and type in the medication name and press search.  Be sure to review this website for more information and tips on getting your lipids down, including diet, exercise and lifestyle changes. 

 

I hope this has been helpful.

 

Martin Cane, M.D.

I just started taking this medication and immediately I am having pain in my right inner thigh area causing me trouble walking upon rising in the morning. It goes away but does come and go later in the day.

STOP THE DRUH IMMEDIATELY AND TALK WITH YOUR DOCTOR. There is absolutely no harm in stopping a statin cold turkey. You are having a potentially serious known side effect of these drugs and it MUST be discontinued.

My mother has been taking Simvasatatin 20mg for nearly 3 yrs, she had a heart attack 10 years ago and also s stroke. The last 2 years she has been complaining of 'feeling not with it' in her head, Dizzyness / cotton wool feeling. And she finds it difficult to walk long distances. Before thaking the tablets she was a very healthy 70 year old woman. Shall i advise her to stop taking for a couple of weeks and see if she feels better>

my dr from the u of m told me the reason you take it at night is because that is when the bad cholesterol remakes more and this slowes it down, and that is why you have to have a blood test 2 weeks after starting to make sure you are still making enough and why you need testing regular...does it make me want to start using it NO but what else is a person to do...it scares the hell out of me putting something else man made in my body...as i stare at my first new bottle....

Me too. Im looking at the posible side effects, and my doctor said it may cause muscle pain, but not likely. And no grapefruit juice...? What is that about. I too do not like the idea of changing blood chemistry around, but the alterative is worse I suppose. Wonder if ther are thosee out there who have indeed had side effects?

I am currently taking 1/2 tablets of 10mg Crestor, at my doctors request. The 10mg was too much he thought.  I am changing to Simvastatin.  He prescribed 20mg.  Is this equivalent?  Or, where can you go to see what mg's are equivalent of two different durgs.   Thanks.

My insurance company doesn't want to pay for the high cost of Lipitor.  So,my doctor substituted Simvastatin 20 mg.  The ban on generic Lipitor runs out Nov. 2011, I understand.  I took Lipitor for 5 years before changing to Simvastatin.  I haven't had any side effects.

I have been on Simvistatin/Zocor 20 for about 15 years and have no known side effects.   I stop taking it when I have Grapefruit.  I do not understand why though.

Ugh...there is not enough room here, nor is this the right forum for me to go on about the utterly flawed science behind the cholesterol myth and the big pharma statin fraud. Suffice it to say...if you have having ANY muscle pain from these drugs STOP THEM IMMEDIATELY. If you, or a relative, beginto have neurologic or mental impairment including depression, "dementia", alzheimer like symptoms, confusion, memory loss, ANY cognition issues...STOP THE DRUG IMMEDIATELY.

 

If you are over 70, lowering your cholesterol may very well kill you. DO NOT TAKE A STATIN. If you are under 40 and someone wants you to take a statin ASK THEM WHAT LONG TERM EFFECTS CAN BE EXPECTED ON YOUR BRAIN AND FOR RESEARCH WHICH BACKS UP THEIR "OH THAT'S NOT A PROBLEM" RESPONSE. I

 

If you are anyone else...DO YOUR HOMEWORK BEFORE YOU AGREE TO TAKE A STATIN...I HAVE GIVEN ANESTHESIA FOR 20 YEARS AND I WOULD NOT TOUCH A STAIN WITH A 10 FOOT POLE. NOR DO I ALLOW MY FAMILY TO TAKE THEM. This is CRAP science and a multibillion dollar fraud...that CAN leave you a blubbering idiot, or kill you.

Can you tell me more please?  I am just turning 70 and my cardio doc just yesterday prescribed 20mg of simvastatin.  I have yet to fill it due to all I have read about the side effects.  Your posting is most vivid.  I lead a very active life style, walking 60 minutes daily, lifting weights, avoiding stress and carefully monitoring my diet.  Still, my levels are all high.  The doc says my body makes cholesterol.  I do not know what more I can do to avoid a medical problem in this regard.  My e-mail address is:  donmccabe7@yahoo.com  Any further advice you can give me would be most welcome.  I do not want to be a walking statistic, and I really feel good right now.  Taking this medicine might just throw me way out of balance.  Thank you for your attention to my inquiry.

Hi, my doctor prescribed me simvastatin for 1 month after my lab result  to lower my slight bad cholesterol.I have been taking simvastatin 20mg for 10days now but it disturbed my period making it delay from its regular cycle. I wonder if it is one of the side effects because it is not among those listed side effects?My activities are the same and im not having intimate relationship. Thank you
