Drugs reference index «Niacin/Lovastatin»


Generic Name: Niacin/Lovastatin (NYE-a-sin/LOE-va-STAT-in)Brand Name: Advicor

Niacin/Lovastatin is used for:

Improving cholesterol levels and lowering very high serum triglyceride levels, in combination with diet and exercise. It may also be used for other conditions as determined by your doctor.

Niacin/Lovastatin is a vitamin (niacin) and HMG-CoA reductase inhibitor (lovastatin) combination. Lovastatin works by blocking an enzyme (HMG-CoA reductase) that is necessary for the production of cholesterol. Exactly how niacin works is not totally understood. It is thought to work in the liver by blocking the production of low-density lipids (bad cholesterol) and increasing the production of high-density lipids (good cholesterol).

Do NOT use Niacin/Lovastatin if:

  • you are allergic to any ingredient in Niacin/Lovastatin
  • you are pregnant or breast-feeding
  • you have active liver or peptic ulcer disease, abnormal liver tests, or a history of bleeding arteries
  • you are taking clofibrate, gemfibrozil, an HIV protease inhibitor (eg, ritonavir), an azole antifungal (eg, itraconazole), a macrolide antibiotic (eg, clarithromycin), a ketolide (eg, telithromycin), or mibefradil

Contact your doctor or health care provider right away if any of these apply to you.

How to use Niacin/Lovastatin :

Use Niacin/Lovastatin as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • If you take 1 dose daily, take Niacin/Lovastatin by mouth at bedtime with a low-fat snack (eg, low-fat yogurt, banana, crackers with a glass of milk) to minimize flushing and upset stomach, unless directed otherwise by your doctor.
  • Take Niacin/Lovastatin 1 hour before or 4 to 6 hours after taking cholestyramine.
  • Swallow Niacin/Lovastatin whole. Do not break, crush, or chew before swallowing.
  • Do not eat grapefruit or drink grapefruit juice at the same time you take Niacin/Lovastatin .
  • Eating grapefruit or drinking grapefruit juice may increase the amount of Niacin/Lovastatin in your blood, which may increase your risk for serious side effects. The risk may be greater with large amounts of grapefruit or grapefruit juice. Avoid large amounts of grapefruit or grapefruit juice (eg, more than one quart daily) while you are using Niacin/Lovastatin . Talk with your doctor or pharmacist if you have questions about including grapefruit or grapefruit juice in your diet while you are taking Niacin/Lovastatin .
  • Avoid drinking alcohol or hot drinks before taking Niacin/Lovastatin to reduce the risk of an uncomfortable side effect caused by niacin (flushing). Taking non-enteric-coated aspirin or an aspirin-like medicine (such as a nonsteroidal anti-inflammatory drug [NSAID] such as ibuprofen or naproxen) 30 minutes before taking Niacin/Lovastatin may help reduce the risk of this side effect.
  • It may take several weeks for Niacin/Lovastatin to work. Do not stop using Niacin/Lovastatin without checking with your doctor.
  • If you miss a dose of Niacin/Lovastatin , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Niacin/Lovastatin .

Important safety information:

  • Niacin/Lovastatin may cause dizziness. These effects may be worse if you take it with alcohol or certain medicines. Use Niacin/Lovastatin with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
  • Flushing occurs with Niacin/Lovastatin and may last for several hours. Flushing usually subsides after several weeks of consistent use. Talk with your doctor if flushing becomes bothersome. If flushing at night awakens you, get up slowly, especially if you feel dizzy or faint, or you are taking blood thinners.
  • Daily use of alcohol may increase your chance for serious side effects. Limit alcoholic beverages.
  • For best results, Niacin/Lovastatin should be used alone with exercise, a low-cholesterol/low-fat diet, and a weight loss program if you are overweight. Follow the diet and exercise program given to you by your health care provider.
  • Niacin/Lovastatin is only recommended if you have taken either lovastatin or long-acting niacin alone before and may need to further reduce your cholesterol and/or triglyceride levels. Tell your doctor if you have not taken either lovastatin or long-acting niacin before starting treatment with Niacin/Lovastatin . Also tell your doctor if you have been taking a short-acting form of niacin before you begin taking Niacin/Lovastatin . It is recommended that you take long-acting niacin for several weeks before using Niacin/Lovastatin so your body can adjust to its effects.
  • Certain medical conditions, including low blood pressure; severe infection; uncontrolled seizures; or serious metabolic, endocrine, or electrolyte problems, may increase your risk for side effects that can result in kidney problems while taking Niacin/Lovastatin . Contact your doctor if you develop one of these conditions.
