What the medication is used for

Dom-PRAVASTATIN is available only with your physician's prescription. It is to be used as an adjunct to a medically recommended and carefully supervised diet for the long-term treatment of hypercholesterolemia and is not a substitute for such a diet. This has been shown to decrease the chances of experiencing a first or second heart attack, or stroke, and may help prevent heart disease if caused by cholesterol clogging the blood vessels, or slow the progression of atherosclerosis (hardening) of the arteries that nourish your heart, so-called coronary heart disease (CHD). In addition, depending on your condition, your physician may recommend an appropriate regimen of exercise, weight control and other measures.

What it does

Dom-PRAVASTATIN lowers the level of cholesterol, particularly Low Density Lipoprotein (LDL) cholesterol, in the blood. Dom-PRAVASTATIN reduces cholesterol production by the liver and induces some changes of cholesterol transport and disposition in the blood and tissues.

When it should not be used

Do not use Dom-PRAVASTATIN if you:

  • are pregnant, since its use in the event of pregnancy may harm the unborn. Only female patients who are highly unlikely to conceive can be candidates for Dom-PRAVASTATIN treatment. In the event of pregnancy during treatment, Dom-PRAVASTATIN should be discontinued and the physician should be informed.
  • know that you are allergic to pravastatin or any of the non-medicinal ingredients of Dom-PRAVASTATIN.

Interactions with this medication

Dom-PRAVASTATIN may interact with other drugs, including those you take without a prescription. You must tell your doctor or pharmacist about all drugs, including prescription and non-prescription, herbal products and supplements, you are taking or planning to take before you take Dom-PRAVASTATIN.

You should tell your doctor if you are taking other cholesterol lowering medication such as fibrates (gemfibrozil, fenofibrate), niacin, or ezetimibe. If you take these drugs and Dom-PRAVASTATIN together, you may be at an increased risk of myopathy (muscle disease with aching or weakness).

If you are taking a bile acid-binding resin (such as cholestyramine, colestipol), your doctor will recommend that you take Dom-PRAVASTATIN either one hour or more before or at least four hours following the resin. Taking them together causes lower amounts of Dom-PRAVASTATIN in the blood, making it less effective.

If you are taking cyclosporine, your doctor may need to adjust the dose of Dom-PRAVASTATIN.

If you are taking certain antibiotics (such as azithromycin or clarithromycin) to treat an infection your doctor may need to adjust the dose of Dom-PRAVASTATIN.

Excessive alcohol intake should be avoided when taking Dom-PRAVASTATIN. Tell your doctor if you regularly drink three or more alcoholic drinks daily.

Proper use of this medication
  • Do not change the dose unless directed by a doctor.
  • Dom-PRAVASTATIN should be taken as a single dose at bedtime, as prescribed by your physician.
  • Your physician will monitor your clinical condition and your blood tests at regular intervals. It is important to have these check-ups done on schedule. Please keep your appointments accurately.
  • Notify your physician about any illness which may develop during your treatment with Dom-PRAVASTATIN and about any new prescription or non-prescription medication you may take. If you require medical help for other reasons, inform the attending physician that you are taking Dom-PRAVASTATIN,
  • Notify your physician if you are going to have major surgery or have sustained a severe injury,
  • Notify your physician of any muscle pain, tenderness or weakness developing during treatment with Dom-PRAVASTATIN (see SIDE EFFECTS AND WHAT TO DO ABOUT THEM).

Usual adult dose

The recommended starting dose is 20 mg once daily at bed time. Patients who require a large dose reduction in cholesterol may be started at 40 mg once daily. The dose of 80 mg once daily should be reserved for patients who do not achieve their treatment goal with lower doses. Dom-PRAVASTATIN may be taken without regard to meals.

Overdose

If you think you have taken too much Dom-PRAVASTATIN contact your doctor, pharmacist, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.
