What is simvastatin for?

Simvastatin is a type of statin, a group of lipid-regulating medicines used to lower cholesterol in patients at increased risk of cardiovascular disease. It is used in combination with a healthy lifestyle and diet to reduce the level of “bad” cholesterol in the blood and raise the level of “good” cholesterol.

How does simvastatin work?

Cholesterol is a fatty substance produced by the liver that plays an important role in the functioning of all cells in the body. Having a high level of high-density lipoprotein (HDL), or “good” cholesterol, in the blood is good for you, but a high level of low-density lipoprotein, “bad” cholesterol, can build up the arteries and cause a blockage, creating a high risk of heart attack or stroke. Simvastatin works to inhibit an enzyme in the liver responsible for the production of LDL cholesterol, thus reducing overall levels in the blood. It’s used in combination with lifestyle modification, e.g. maintaining a healthy weight, eating a healthy diet that is low in saturated fats and exercising regularly.

How long do I need to take simvastatin for?

Statins such as simvastatin are usually taken for life, as the benefits will wear off once treatment ends. For this reason, they are usually only prescribed to patients at high risk of cardiovascular disease; such as those with a history of stroke or heart attack. The benefits of statins increase over time, and coming off them suddenly can be dangerous. Never stop taking statins without first consulting a doctor.

Treatment Options

How to switch high cholesterol medication

Simvastatin is a prescription medication that must only be taken following consultation with a doctor. It can also be purchased at a low, 10 mg dose from a pharmacy - however, you should still consult a doctor before switching to this medication. Your doctor will place you on a low-cholesterol diet and start by prescribing you a low dose which may be increased gradually over time.

Simvastatin vs other statins

There are five types of statin available on prescription in the UK. The main difference between statins is their lowering effect on cholesterol levels: simvastatin, fluvastatin and pravastatin are low-intensity statins, which are sufficient for lowering cholesterol in most patients. For patients with very high cholesterol levels, a high-intensity statin such as atorvastatin or rosuvastatin may be more suitable. 

People react differently to different statins, so if you are experiencing troublesome side effects speak to your doctor about the possibility of switching to a different statin.


Is simvastatin a cure?

Simvastatin is not a cure for high cholesterol, and your cholesterol levels will rise again if you stop taking this medication. However, simvastatin helps to lower cholesterol and reduce the risk of experiencing a heart attack or stroke. It is most effective when accompanied by the appropriate lifestyle and diet. To make the best of simvastatin, you should follow a healthy, low-cholesterol diet, exercise regularly, quit smoking and lose weight if you are overweight.

How can I tell if simvastatin is working?

You will not be able to feel simvastatin working. However, your doctor may wish to conduct regular blood tests to monitor the level of your cholesterol. It is more important to concentrate on leading a healthy lifestyle to make the most of the benefits of simvastatin.

Is simvastatin a blood thinner?

Simvastatin is not a blood thinner. It works by reducing the level of “bad” cholesterol in the blood and increasing the level of “good” cholesterol. It may be taken in combination with blood-thinning medication if you are at increased risk of blood clots.

How is high cholesterol diagnosed?

There are not usually any symptoms of high cholesterol and diagnosis is through blood testing.

How can I lower my cholesterol?

Limiting intake of foods that contain cholesterol, saturated fat and trans fat is the easiest way to manage cholesterol. Simvastatin is prescribed in addition to dietary changes if; your levels of cholesterol have not been lowered by diet or exercise, you are at a greater risk of a stroke or heart attack, you are suffering from coronary heart disease, or you have inherited a condition that increases your cholesterol e.g. homozygous familial hypercholesterolaemia.
