Lovastatin is used together with diet, weight-loss, and exercise to reduce the risk of heart attack and stroke and to decrease the chance that heart surgery will be needed in people who have heart disease or who are at risk of developing heart disease. Lovastatin is also used to decrease the amount of cholesterol (a fat-like substance) and other fatty substances in the blood. Lovastatin is in a class of medications called HMG CoA reductase inhibitors (statins). It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body.
Lovastatin comes as a tablet and an extended-release (long-acting) tablet to take by mouth. The regular tablet usually is taken once or twice a day with meals. The extended-release tablet usually is taken once a day at bedtime. Take lovastatin at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lovastatin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole; do not split, chew, or crush them.
Your doctor may start you on a low dose of lovastatin and gradually increase your dose, not more than once every 4 weeks.
Continue to take lovastatin even if you feel well. Do not stop taking lovastatin without talking to your doctor.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Eat a low-cholesterol, low-fat diet, which includes cottage cheese, fat-free milk, fish, vegetables, poultry, and egg whites. Use monounsaturated oils such as olive, peanut, and canola oils or polyunsaturated oils such as corn, safflower, soy, sunflower, cottonseed, and soybean oils. Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, olives, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods.
Avoid drinking large amounts (more than 1 quart [approximately 1 liter] per day) of grapefruit juice while taking lovastatin.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
