Statins
Fluvastatin
A statin that lowers LDL ("bad") cholesterol to reduce the risk of heart attack and stroke; usually taken at night.
What is Fluvastatin?
Fluvastatin is a statin used to lower cholesterol, particularly LDL ("bad") cholesterol, to reduce the risk of heart attack and stroke. It blocks an enzyme the liver uses to make cholesterol, so circulating levels fall. It is usually taken at night, and any severe or widespread muscle pain, or dark urine, should be reported.
Education and reference only. This is a plain-language guide to Fluvastatin — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Fluvastatin is a statin prescribed in the UK to lower cholesterol and reduce the risk of heart attacks and strokes. It is used both to prevent a first cardiovascular event in people at raised risk and to protect people who already have heart or vascular disease. It is taken regularly as a long-term medicine and works quietly in the background; the benefit is measured in reduced cardiovascular risk over years rather than in how you feel day to day.
How it works
Fluvastatin blocks an enzyme in the liver (HMG-CoA reductase) that the body uses to make cholesterol. With less cholesterol being produced, the liver pulls more LDL cholesterol out of the blood, so circulating levels fall. Lower LDL means less cholesterol is laid down in artery walls, which is how statins reduce the risk of heart attacks and strokes over time.
Company & origin
Originated / developed by: Developed by Sandoz (now part of Novartis)..
Fluvastatin was the first fully synthetic statin, introduced in the 1990s and marketed in the UK as Lescol for lowering cholesterol.

Practical use
How to take Fluvastatin
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- Take it regularly, usually at night, as the body makes most cholesterol overnight.
- Take it long-term — stopping it lets cholesterol and risk drift back up.
- Report severe, widespread or persistent muscle pain, tenderness or weakness, or dark-coloured urine.
- Tell your prescriber about all your other medicines, as some interact with statins.
- If you miss a dose, take it when you remember unless it is nearly time for the next one — do not double up.
- Avoid large amounts of alcohol, which can affect the liver.
Weighing it up
Advantages & disadvantages of Fluvastatin
Advantages
- It effectively lowers LDL ("bad") cholesterol and reduces the risk of heart attack and stroke.
- It is generally well tolerated, and many reported muscle symptoms turn out not to be caused by the statin.
- It has relatively few interactions compared with some other statins.
Disadvantages
- It is usually taken at night rather than at any time of day.
- Muscle aches can occur and, rarely, a more serious muscle problem.
- It needs liver blood tests before and during treatment.
- It must not be used in pregnancy.
Practical use
Good to know
Fluvastatin is usually taken at night, as the body makes most of its cholesterol overnight. It is taken long-term, and stopping it allows cholesterol — and risk — to drift back up. Muscle aches are the side effect people worry about most; mild aches are common, but you should report severe, widespread or persistent muscle pain, tenderness or weakness, or dark-coloured urine, as these can rarely signal a more serious muscle problem. Liver blood tests are checked before and during treatment.
Who should not take it / use with caution
- People with active liver disease or unexplained, persistently raised liver blood tests.
- Women who are pregnant, planning pregnancy or breastfeeding — statins are stopped beforehand.
- People with certain muscle conditions, or who drink heavily, used with caution.
Monitoring
- Liver blood tests before starting and during treatment.
- A cholesterol blood test to check the response.
- Reviewing any muscle symptoms and reporting severe or widespread pain.
Side effects
- Muscle aches and pains.
- Headache, tummy upset, wind or nausea.
- Disturbed sleep.
- Rarely, a serious muscle problem (severe pain or weakness with dark urine) or raised liver blood tests.
Key interactions
- Some medicines that affect the liver, including certain others used to lower cholesterol, which can increase muscle side-effect risk.
- Heavy alcohol use, which adds to the strain on the liver.
- Tell your prescriber about all your medicines, including over-the-counter and herbal ones.
Available as: Capsules and modified-release tablets.
Answers
Fluvastatin: frequently asked questions
Why is fluvastatin taken at night?
The body makes most of its cholesterol overnight, so taking fluvastatin in the evening can make it more effective. Follow the timing your prescriber or pharmacist advises.
Should I worry about muscle aches on fluvastatin?
Mild muscle aches are common and usually harmless. However, report severe, widespread or persistent muscle pain, tenderness or weakness, or dark-coloured urine, as these can rarely signal a more serious muscle problem that needs checking.
Can I stop fluvastatin if my cholesterol is normal?
Your cholesterol is normal because the medicine is working. Stopping it usually lets cholesterol — and your risk — rise again, so do not stop without discussing it with your prescriber.
Why do I need liver blood tests?
Statins can occasionally affect the liver, so liver blood tests are done before you start and during treatment to make sure everything is fine.
Can I drink alcohol on fluvastatin?
Small amounts are usually fine, but avoid heavy drinking, which can strain the liver. If you drink regularly or heavily, tell your prescriber.
