Simvastatin belongs to a group of medicines called statins, which are lipid-lowering medicines. Simvastatin lowers the levels of cholesterol and fatty substances known as triglycerides in your blood.

Most cholesterol is produced in our body by the liver. This happens mainly at night, which is why it is recommended that Simvastatin Tablets are taken in the evening or at night. Simvastatin tablets are used, together with diet if you have:

  • Raised cholesterol levels (primary hypercholesterolaemia) or elevated fat levels (mixed hypercholesterolaemia) in your blood.
  • Homozygous familial hypercholesterolaemia (an inherited disease that causes raised levels of cholesterol.)
  • Coronary heart disease (CHD) or are at high risk of CHD (because you have diabetes, history of stroke, or other blood vessel disease.) Simvastatin tablets may reduce the risk of heart disease by keeping your arteries clear, even if your cholesterol levels are normal.

It is generally accepted that a high cholesterol level in your blood increases the risk of heart disease. The higher the level, the greater the risk. The presence of other factors, such as existing heart disease, high blood pressure, high blood sugar (diabetes), increased weight, lack of exercise and smoking adds to the risk of getting or worsening of heart disease with high cholesterol.

In most people there are no obvious signs of high cholesterol. Your doctor will measure the levels of cholesterol with a blood test.


DO NOT TAKE Simvastatin tablets if:

  • you are hypersensitive (allergic) to simvastatin or any of the other ingredients of the tablets (listed in section 6)
  • you have liver problems
  • you are pregnant or breast-feeding
  • you are taking:
  • antifungal drugs such as itraconazole or ketoconazole
  • antibiotics erythromycin, telithromycin or clarithromycin
  • the antidepressant nefazodone
  • a medicine for the treatment of HIV infections (HIV protease inhibitor) such as indinavir, nelfinavir, ritonavir or saquinavir

If you think any of these apply to you talk to your doctor before taking the tablets.

Before taking Simvastatin tablets, it is important to tell your doctor:

  • if you are taking anticoagulants (drugs that prevent blood clots such as warfarin)
  • if you have an intolerance to some sugars
  • about your present and past health problems, especially muscle problems, diabetes and kidney problems, as well as any allergies.
  • if you consume large quantities of alcohol
  • if you have a history of liver disease
  • if you are due to have major surgery. You may need to stop taking Simvastatin tablets for a while.
  • if you have severe respiratory failure
  • if you have diabetes or are at risk of developing diabetes while you are on this medicine your doctor will monitor you closely . You are likely to be at risk of developing diabetes if you have high levels of sugars and fats in your blood, are overweight and have high blood pressure.

Muscle problems with Simvastatin

On rare occasions there is a risk of muscle problems, which may be serious. The doctor may perform a blood test to check the condition of your muscles before and after starting treatment.

Contact your doctor immediately if you experience unexplained muscle pain, tenderness or weakness

The risk of developing muscle problems is greater with high doses of Simvastatin and in certain patients.

Tell your doctor before you take Simvastatin if any of the following apply to you:

  • you are female
  • you are more than 65 years old
  • you have kidney problems
  • you have thyroid problems
  • you or close family members have a hereditary muscle disease
  • you have ever had muscle problems during treatment with cholesterol lowering medicines called statins (e.g. simvastatin, atorvastatin, pravastatin) or fibrates (e.g. gemfibrozil)
  • you have a history of alcohol abuse
  • you are taking certain other medicines (see ‘Taking other medicines’ below):

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, even those not prescribed.

It is particularly important that your doctor knows if you are taking any of the following medicines as they may cause an increased risk of muscle problems:

  • ciclosporin, a medicine used to suppress the immune system
  • antifungal agents (such as itraconazole or ketoconazole)
  • medicines for the treatment of HIV infections (such as indinavir, nelfinavir, ritonavir and saquinavir)
  • other cholesterol lowering medicines such as fibric acid derivatives e.g. gemfibrozil, bezafibrate, fenofibrate
  • antibiotic medicines containing erythromycin, telithromycin, fusidic acid or clarithromycin
  • nefazodone (an antidepressant)
  • amiodarone (used to treat irregular heart beat)
  • verapamil diltiazem or amlodipine (used to treat high blood pressure, angina or other heart conditions).
  • danazol (used to treat endometriosis)

Also tell your doctor or pharmacist if you are taking:

  • oral anticoagulants (drugs that prevent blood clots), such as warfarin, phenprocoumon or acenocumarol, as simvastatin may increase the risk of bleeding
  • niacin or nicotinic acid (cholesterol lowering medicines) containing products, especially if you are Chinese.
