Know the basics

What is lovastatin used for?

Lovastatin is used along with a proper diet to help lower “bad” cholesterol and fats (such as LDL, triglycerides) and raise “good” cholesterol (HDL) in the blood. It belongs to a group of drugs known as “statins.” It works by reducing the amount of cholesterol made by the liver. Lowering “bad” cholesterol and triglycerides and raising “good” cholesterol decreases the risk of heart disease and helps prevent strokes and heart attacks.

In addition to eating a proper diet (such as a low-cholesterol/low-fat diet), other lifestyle changes that may help this Lovastatin work better include exercising, losing weight if overweight, and stopping smoking. Consult your doctor for more details.

How should I take lovastatin?

Take Lovastatin by mouth as directed by your doctor, usually once daily with your evening meal. Some patients may be directed to take Lovastatin twice daily.

Dosage is based on your medical condition, response to treatment, age, and other Lovastatin you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

Avoid eating grapefruit or drinking grapefruit juice while using Lovastatin unless your doctor instructs you otherwise. Grapefruit can increase the amount of Lovastatin in your bloodstream. Consult your doctor or pharmacist for more details.

If you also take certain other drugs to lower your cholesterol (bile acid-binding resins such as cholestyramine or colestipol), take lovastatin at least 1 hour before or at least 4 hours after taking these Lovastatin. These products can react with lovastatin, preventing its full absorption.

Take Lovastatin regularly in order to get the most benefit from it. Remember to take it at the same time(s) each day. It is important to continue taking Lovastatin even if you feel well. Most people with high cholesterol or triglycerides do not feel sick.

It is very important to continue to follow your doctor’s advice about diet and exercise. It may take up to 4 weeks before you get the full benefit of Lovastatin.

How do I store lovastatin?

Lovastatin is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store Lovastatin in the bathroom or the freezer. There may be different brands of Lovastatin that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush Lovastatin down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.
