Niacin XR and Lovastatin Precautions
Serious side effects have been reported with niacin XR and lovastatin including the following:
- Liver Dysfunction. Cases of severe hepatic toxicity, including fulminant hepatic necrosis, have occurred in patients who have substituted sustained-release niacin products for immediate-release niacin at equivalent doses. Niacin XR and lovastatin should be used with caution in patients who consume substantial quantities of alcohol and/or have a past history of liver disease. Active liver disease or unexplained transaminase elevations are contraindications to the use of niacin XR and lovastatin. Niacin preparations and lovastatin have been associated with abnormal liver tests. It is recommended that liver enzyme tests be obtained prior to initiating therapy with niacin XR and lovastatin and repeated as clinically indicated.
- Myopathy/Rhabdomyolysis. Lovastatin occasionally cause myopathy, which is manifested as muscle pain or weakness associated with grossly elevated creatine kinase. Rhabdomyolysis, with or without acute renal failure secondary to myogobinuria, has been reported rarely and can occur at any time. The risk of rhabdomyolysis is increased by concomitant use of lovastatin with the following:
- strong inhibitors of CYP3A4: itraconazole, ketoconazole, posaconazole, erythromycin, clarithromycin, telithromycin, boceprevir, telaprevir, nefazodone, large quantities of grapefruit juice (>1 quart daily).
- gemfibrozil: The combined use of lovastatin with gemfibrozil should be avoided.
- other fibrates: The benefit of further alterations in lipid levels by the combined use of lovastatin with other fibrates should be carefully weighed against the potential risks of this combination.
- cyclosporine: The combined use of lovastatin and cyclosporine should be avoided
- danazol, diltiazem, or verapamil with higher doses of lovastatin: The dose of lovastatin should not exceed 20mg as the risk of myopathy increases at higher doses
- amiodarone: The dose of lovastatin should not exceed 40mg.
- colchicine: Use caution
- Ranolazine: Dose adjustment of lovastatin may be considered.

- are allergic to niacin, lovastatin, or any component of this medication

Niacin XR and lovastatin falls into category X. It has been shown that women taken niacin XR and lovastatin during pregnancy may have babies born with problems. There are no situations where the benefits of the medication for the mother outweigh the risks of harm to the baby. These medicines should never be used by pregnant women.
