Name: Advicor

What is the dosage for niacin and lovastatin?

The recommended starting dose for Advicor is one tablet (500/20 mg). Doses can be increased by 500 mg of niacin every 4 weeks based on the response of the blood cholesterol level. Doses greater than 2000/40 mg are not recommended. Individuals already stabilized on niacin extended-release tablets can be directly switched to the niacin equivalent dose of Advicor. Individuals taking extended-release niacin and lovastatin separately can be switched to an equivalent dose of Advicor.

Other forms of niacin (for example, sustained-release, timed-release or immediate-release) are not equivalent to extended-release niacin in Advicor. Therefore, Advicor is not interchangeable with these niacin preparations, and patients taking these preparations should be switched and stabilized on extended-release niacin before switching to Advicor.

Advicor should be administered at bedtime with a low fat snack. Since there is evidence that at least some drugs in the same class as lovastatin lower cholesterol more when taken at night than in the morning. If Advicor is discontinued for longer than 7 days, therapy should be resumed at the lowest dose.

Advicor and Lactation

Tell your doctor if you are breastfeeding or plan to breastfeed. No studies have been conducted with Advicor in nursing mothers. Because of the potential for serious adverse reactions in nursing infants from lipid-altering doses of niacin and lovastatin, Advicor should not be taken while a woman is breastfeeding.

Niacin has been reported to be excreted in human milk. It is not known whether lovastatin is excreted in human milk.

Proper Use of Advicor

Take this medicine only as directed by your doctor. Do not take more or less of it and do not take it more often or for a longer time than your doctor ordered. Also, this medicine works best if there is a constant amount in the blood. To help keep this amount constant, do not miss any doses and take the medicine at the same time each day.

In addition to this medicine, your doctor may change your diet to one that is low in fat, sugar, and cholesterol. Carefully follow your doctor's orders about any special diet.

Swallow the extended-release tablet whole. Do not break, crush, or chew it.

It is best to take this medicine at bedtime, with a low-fat meal or snack. Do not take it on an empty stomach.

If you are taking danazol (Danocrine®), diltiazem (Cardizem®), or verapamil (Calan®, Isoptin®, Verelan®) together with lovastatin, your lovastatin dose should not be higher than 20 milligrams (mg) per day, unless otherwise directed by your doctor. Do not use more than 40 mg per day of lovastatin together with amiodarone (Cordarone®). When used together with higher doses of lovastatin, these medicines may increase your risk of muscle injury and could result in kidney problems.

Tell your doctor if you regularly drink grapefruit juice. Drinking large amounts of grapefruit juice (more than 1 quart each day) while taking this medicine may increase your risk of muscle injury and could result in kidney problems.

Do not drink large amounts of alcohol with lovastatin. This could cause liver injury.

Advicor is contraindicated in patients with a known hypersensitivity to niacin, lovastatin or any component of this medication, active liver disease or unexplained persistent elevations in serum transaminases (see WARNINGS), active peptic ulcer disease, or arterial bleeding.

Concomitant administration with strong CYP3A4 inhibitors (e.g., itraconazole, ketoconazole, posaconazole, HIV protease inhibitors, boceprevir, telaprevir, erythromycin, clarithromycin, telithromycin and nefazodone) (see WARNINGS, Myopathy/Rhabdomyolysis).

Pregnancy and lactation - Atherosclerosis is a chronic process and the discontinuation of lipid-lowering drugs during pregnancy should have little impact on the outcome of long-term therapy of primary hypercholesterolemia. Moreover, cholesterol and other products of the cholesterol biosynthesis pathway are essential components for fetal development, including synthesis of steroids and cell membranes. Because of the ability of inhibitors of HMG-CoA reductase, such as lovastatin, to decrease the synthesis of cholesterol and possibly other products of the cholesterol biosynthesis pathway, Advicor is contraindicated in women who are pregnant and in lactating mothers. Advicor may cause fetal harm when administered to pregnant women. Advicor should be administered to women of childbearing age only when such patients are highly unlikely to conceive. If the patient becomes pregnant while taking this drug, Advicor should be discontinued immediately and the patient should be apprised of the potential hazard to the fetus (see PRECAUTIONS, Pregnancy).
