Fluvastatin (Oral)

Fluvastatin is used alongside a healthy diet to treat patients with high levels of cholesterol and triglycerides in the blood stream.


Fluvastatin is a treatment that helps to lower the level of triglycerides and cholesterol in the blood. Patients with high levels of these fats in the blood stream can develop serious medical problems as fat begins to clog the arteries and the blood vessels in the patient.

Fluvastatin is a HMG-CoA reductase inhibitor, also known as a statin, that works to block an enzyme needed for the body to produce cholesterol. By making the body incapable of producing cholesterol, this fat is instead excreted from the body and is unable to clog the arteries and blood vessels of the patient.

Fluvastatin can also be used in the prevention of heart and blood vessel problems in certain patients who are at risk from such problems.

This medication will only be effective if used in conjunction with a correct and healthy balanced diet. Patients should follow the dietary advice given to them by the doctor when this medication is prescribed.

Fluvastatin is available either as Lescol or Lescol XL as capsules or as extended release tablets.

Fluvastatin is used to help lower the level of cholesterol and triglycerides in the blood of patients. Commonly it is used in patients with high levels of cholesterol but may also be used to prevent heart or blood vessel problems from developing in certain situations of increased risk.

Fluvastatin is a medication that works by blocking an enzyme in the body. This enzyme enables the body to produce cholesterol and by blocking its effective production Fluvastatin can cause more fats to be excreted from the body instead of being absorbed into the blood.

Fluvastatin is prescribed for the treatment of high levels of cholesterol along with a dietary plan and an exercise plan that should be followed at all times. Failure to follow this exercise plan will lead to spikes in cholesterol that will put the patient at risk of serious medical conditions. For the treatment to be effective you must follow the advice of your doctor and must also ensure that you take the medication regularly and as ordered.

Patients should endeavor to bring their cholesterol levels down naturally. Failing to do so will mean they have to keep taking Fluvastatin indefinitely and this will put them at increased risk of side effects occurring.

This medication should not be used in pregnant women and caution should be used in patients who are likely to become pregnant. This medication is known to cause fetal malformations when used in pregnant women. The medication can also be passed on through breastmilk and is known to cause problems in infants who are nursing from a mother who is using the medication.

Fluvastatin can cause a wide range of medical conditions to develop. The risk of developing these will increase with prolonged use and higher doses. The patient should ensure that they understand the risk of these potential conditions before beginning use and should take into account any other medical conditions they have that might increase the risk.
