Lipidil

Action

Inhibits triglyceride synthesis in liver, reducing levels of low- and very-low-density lipoproteins. Also increases uric acid secretion.

Interactions

Drug-drug. Bile acid sequestrants (resins): decreased absorption and efficacy of fenofibrate

Immunosuppressants, other nephrotoxic drugs: increased risk of renal toxicity

Oral anticoagulants: increased risk of bleeding

Statins (such as simvastatin): rhabdomyolysis, acute renal failure

Drug-diagnostic tests. Alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, blood urea nitrogen, creatinine, gamma-glutamyltransferase, uric acid: increased values

Granulocytes, hemoglobin, neutrophils, platelets, white blood cells (WBCs): decreased values

Liver function tests: abnormal results

Drug-food. Any food: increased drug absorption

Drug-behaviors. Alcohol use: elevated triglyceride level

Patient monitoring

• Assess creatine kinase and lipid levels and liver function test results.

• Monitor CBC and WBC count. Expect these to decrease at start of therapy, then stabilize.

Patient teaching

• Instruct patient to take with meals for best effect.

• Remind patient that he still needs to follow a triglyceride-lowering diet.

• Caution patient to avoid driving and other hazardous activities until he knows how drug affects concentration and alertness.

• Advise patient to minimize GI upset by eating frequent, small servings of food and drinking plenty of fluids.

• Tell patient that drug may take up to 2 months to alter lipid values.

• Inform breastfeeding patient that she must choose between taking fenofibrate and breastfeeding.

• Tell female patient to inform prescriber if she is pregnant.

• Inform patient that he'll undergo regular blood testing.

• As appropriate, review all other significant and life-threatening adverse reactions and interactions, especially those related to the drugs, tests, foods, and behaviors mentioned above.
