How it Works
About Simvastatin
How does Simvastatin work?
Simvastatin belongs to a group of medicines known as HMG-CoA reductase inhibitors. HMG-CoA reductase is a liver enzyme, which is involved in the production of cholesterol. Medications such as simvastatin block the action of this enzyme, which means that less “bad” LDL cholesterol is produced. As a result, your blood levels of cholesterol are lowered, which is thought to reduce dangerous complications such as stroke and heart attack. Simvastatin also reduces blood levels of other blood fats (for example a type of blood fat called triglycerides).
In addition to taking simvastatin, you must follow a cholesterol lowering diet. Your GP will advise you on how to plan your meals and reduce your intake of cholesterol and saturated fats.
Simvastatin Dosage
Your GP will decide which Simvastatin dosage you need to take. The starting dose is usually 10mg Simvastatin a day. Your GP may need to adjust this dosage and increase it gradually. Once you have reached your cholesterol goal, your GP might decide to lower your dosage.
You may need to take Simvastatin 20mg, 40mg or 80mg, depending on your prescription. The exact dosage depends on how well you adjust to taking the statin and how effectively simvastatin lowers your cholesterol. The maximum daily dosage is 80mg. Patients who suffer from particular health conditions (for example kidney disease) or are taking other medications are often prescribed a low dosage to prevent side effects.
You must not stop taking Simvastatin tablets without consulting your doctor first. If you stop taking Simvastatin, your blood cholesterol levels are likely to increase. This puts you at risk of heart problems and stroke.
How is Simvastatin taken?
Simvastatin tablets need to be taken in the evening, as the medication works more effectively at night. Take your daily dose with a drink of water. Do not chew the tablet but swallow it whole. You can take Simvastatin with or without food.
If you forget to take a Simvastatin dose, take it as soon as you remember. If it is nearly time to take the next dose, skip the missed tablet and continue your treatment as usual.
Simvastatin and Grapefruit
Simvastatin and grapefruit are known to interact. Avoid grapefruit and grapefruit juice while taking Simvastatin. Grapefruit contains components which increase the level of Simvastatin in your blood. This increases your risk of side effects, such as muscle damage.
Simvastatin and alcohol
Alcohol can affect the action of simvastatin, and you should keep your alcohol intake to a minimum whilst you are on simvastatin. You must tell your doctor if you are consuming large amounts of alcohol on a regular basis. Drinking alcohol increases your risk of liver and kidney disease, which means Simvastatin may not be suitable for you.
Can I drive or operate machinery while taking Simvastatin tablets?
You can drive and work with machines during your treatment with Simvastatin. The statin should not have any impact on your ability to concentrate. However, a very small number of patients report feeling dizzy when taking Simvastatin. Speak to your doctor if this happens to you. Do not drive while feeling dizzy.
Who can not take Simvastatin?
Do not take Simvastatin if:
- you are allergic to one of the ingredients in Simvastatin tablets
- you have liver problems
- you are pregnant
- you are breastfeeding
- you are taking any medication which interacts with Simvastatin

Tell your doctor if:
- you have ever had muscle pain, cramps or weakness, or if any member of your family has a muscle disorder or a reaction to drugs for cholesterol

- you will have an operation in the near future
- you suffer from lung disease
Before prescribing Simvastatin tablets, your doctor will take a blood sample to test whether your liver function is normal. During treatment, you will need to attend regular check-ups during which your GP will make sure your treatment is working.
