1. What Dorisin XL is and what it is used for

Dorisin XL contains the active substance fluvastatin sodium which belongs to a group of medicines known as statins, which are lipid-lowering medicines: they lower the fat (lipids) in your blood. They are used in patients whose conditions cannot be controlled by diet and exercise alone.

  • Dorisin XL is a medicine used to treat raised levels of fats in the blood in adults, in particular total cholesterol and so called “bad” or LDL cholesterol, which is associated with an increased risk of heart disease and stroke.
    • in adult patients with high blood levels of cholesterol.
    • in adult patients with high blood levels of both cholesterol and triglycerides (another sort of blood lipid).
  • Your doctor can also prescribe Dorisin XL to prevent further serious cardiac events (e.g. heart attack) in patients who have already had a heart catheterisation, with an intervention in the heart vessel.

2. What you need to know before you take Dorisin XL

Do not take Dorisin XL

  • If you are allergic to fluvastatin or any of the other ingredients of this medicine (listed in section 6).
  • If you currently have liver problems or if you have unexplained, persistently high level of certain liver enzymes (transaminases).
  • If you are pregnant or breast-feeding (see “pregnancy and breast-feeding”).

If any of these apply to you, do not take Dorisin XL and tell your doctor.

Warnings and precautions

Talk to your doctor or pharmacist before taking Dorisin XL

  • if you are taking or have taken in the last 7 days a medicine called fusidic acid, (a medicine for bacterial infection) orally or by injection. The combination of fusidic acid and Dorisin XL can lead to serious muscle problems (rhabdomyolysis).
  • if you previously had a liver disease. Liver function tests will normally be done before you start Dorisin XL, when your dose is increased and at various intervals during treatment to check for side effects.
  • if you have a kidney disease.
  • if you have a thyroid disease (hypothyroidism).
  • if you have a medical history of muscle diseases yourself or in your family.
  • if you had muscle problems with another lipid-lowering medicine.
  • if you regularly drink large amounts of alcohol.
  • if you have a serious infection.
  • if you have very low blood pressure (signs may include dizziness, light-headedness).
  • if you have controlled or uncontrolled excessive muscle exercise.
  • if you are about to have an operation.
  • if you have severe metabolic, endocrine or electrolyte disorders such as decompensated diabetes and low blood potassium.

While you are on this medicine your doctor will monitor you closely if you have diabetes or are at risk of developing diabetes. You are likely to be at risk of developing diabetes if you have high levels of sugars and fats in your blood, are overweight and have high blood pressure.

Check with your doctor or pharmacist before taking Dorisin XL:

  • if you have severe respiratory failure

If any of these apply to you, tell your doctor before taking Dorisin XL. Your doctor will take a blood test before prescribing Dorisin XL.

Also tell your doctor or pharmacist if you have a muscle weakness that is constant. Additional tests and medicines may be needed to diagnose and treat this.

If during treatment with Dorisin XL, you develop symptoms or signs such as nausea, vomiting, loss of appetite, yellow eye or skin, confusion, euphoria or depression, mental slowing, slurred speech, sleep disturbance, tremors or easy bruising or bleeding, these may be signs of liver failure. In such case contact a doctor immediately.
