What is in this leaflet
This leaflet answers some common questions about simvastatin. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you using this medicine against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine. You may want to read it again.
What this medicine is used for
Simvastatin is used:
- to help lower high cholesterol and triglyceride levels (together with dietary changes)
- in people who have coronary heart disease (CHD)
- in people with a high risk of CHD (e.g. diabetes, stroke or other blood vessel disease)
Simvastatin can reduce the risk of a heart attack or stroke, and can reduce the need for hospitalisation due to angina.
Everyone has cholesterol and triglycerides in their blood. The body uses them for many things, such as building cell walls and hormones.
Your body makes cholesterol, but it also comes from food. The body balances the cholesterol it makes with the cholesterol it gets from food. This means if more cholesterol comes from food, less is made by the body. However, if you eat a high-fat diet, your body may not keep this balance and your cholesterol levels rise.
Too much cholesterol or triglycerides can be a problem. When you have high levels of cholesterol, it may 'stick' to the inside of your blood vessels instead of being carried to the parts of the body where it is needed. Over time this can form hard areas (called plaque) on the walls of blood vessels, making it more difficult for the blood to flow. This blocking of your blood vessels can lead to heart attacks, angina and stroke. High cholesterol is more likely to occur with certain diseases or if you have a family history of high cholesterol.
There is usually no symptoms of high cholesterol or triglycerides. Your doctor can measure your cholesterol and triglycerides with a blood test.
There are two types of cholesterol, called LDL and HDL cholesterol. LDL cholesterol is the 'bad' cholesterol that can block vessels. HDL cholesterol is the 'good' cholesterol that is thought to remove bad cholesterol from blood vessels.
How it works
Simvastatin belongs to a group of medicines known as HMG-CoA reductase inhibitors.
Simvastatin works by reducing bad (LDL) cholesterol made by the liver and raises the good (HDL) cholesterol. It may slow the hardening of blood vessels and reduce the risk of developing new plaque.
Simvastatin does not reduce the cholesterol and triglycerides that come from fatty food. Therefore, you also need to follow a low-fat diet while you are taking simvastatin.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed this medicine for another reason.

Safety and effectiveness have not been studied in boys under 10 years of age or in girls who have not yet started their periods.

How to take this medicine
Follow all directions given to you by your doctor or pharmacist carefully. They may differ to the information contained in this leaflet.
If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.
How much to take
Your doctor will tell you how much of this medicine you should take, depending on your condition and whether you are taking other medicines.
The maximum dose of simvastatin is 80 mg per day. This dose should only be used in patients at a high risk of heart problems who have responded to lower doses.
High cholesterol and triglyceride levels:
The usual starting dose is 10 mg or 20 mg taken in the evening.
For CHD or risk of CHD:
The usual starting dose is 40 mg taken in the evening.
How to take it
Swallow the tablets whole with a glass of water.
When to take it
Take this medicine at the same time each day, preferably in the evening. The liver produces its greatest amount of cholesterol when the body is at rest and when there is no dietary intake. For most people, this is at night when asleep. Therefore, this medicine is more effective when taken in the evening, such as after your evening meal, however it can be taken without food.
Taking it at the same time each day will have the best effect and will also help you remember when to take it.
How long to take it for
Continue taking this medicine for as long as your doctor tells you.
Simvastatin helps to lower your cholesterol, but it does not cure your condition. It is important to keep taking your medicine even if you feel well.
Make sure you have enough to last over weekends and holidays.
If you forget to take it
If it is almost time to take your next dose, skip the dose you missed and take your next dose at the usual time.
Otherwise take it as soon as you remember and then go back to taking your medicine as you would normally.
Do not take a double dose to make up for missed doses. This may increase the chance of you experiencing side effects.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
If you take too much (overdose)
Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have taken too much of this medicine. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
