6. Contents of the pack and other information

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 (CHO) or are at high risk of CHO (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, posaconazole or voriconazole
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
• boceprevir or telaprevir (used to treat hepatitis C virus infection)
• gemfibrozil (used to lower cholesterol)
• ciclosporin (used in organ transplant patients)
• danazol (a man-made hormone used to treat endometriosis, a condition in which
the lining of the uterus grows outside the uterus).
• If you are taking or, in the last 7 days, have taken or been given a medicine called fusidic
acid (used to treat bacterial infection)
If you think any of these apply to you talk to your doctor before taking the tablets.
Warnings and precautions
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

you have high levels of sugars and fats in your blood, are overweight and have high

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. This is because on rare occasions, muscle problems can be
serious, including muscle breakdown resulting in kidney damage; and very rare
deaths have occurred. The risk of developing muscle problems is greater with high
doses of Simvastatin and in certain patients.
Also tell your doctor or pharmacist if you have a muscle weakness that is constant.
Additional tests and medicines may be needed to diagnose and treat this.
