Be aware that this drug can cause liver problems, which in some cases have been severe, resulting in the need for a liver transplant or leading to death. If you have any questions or concerns, discuss them with your doctor.
If you are 65 years or older, exercise caution when using this medication, as you may be more susceptible to side effects.
If you are pregnant or planning to become pregnant, consult your doctor to discuss the potential benefits and risks associated with using this medication during pregnancy.
Overdose Information
Overdose Symptoms:
- No specific antidote or symptoms of overdose are known. Symptoms would likely be an exaggeration of known side effects, such as muscle pain, liver enzyme elevations, or gastrointestinal upset.
What to Do:
In case of suspected overdose, contact a poison control center (1-800-222-1222) or seek emergency medical attention immediately. Treatment is generally supportive and symptomatic. Hemodialysis is not effective in removing fenofibric acid from the body.
Drug Interactions
Major Interactions
- Statins (HMG-CoA reductase inhibitors): Increased risk of myopathy/rhabdomyolysis. Use with caution, especially with higher statin doses or in patients with predisposing factors for myopathy. Consider lower doses of both agents.
- Warfarin: Potentiates anticoagulant effect, increasing risk of bleeding. Monitor INR closely and adjust warfarin dose as needed.
- Cyclosporine: May impair renal function, leading to increased fenofibric acid levels and potential nephrotoxicity. Monitor renal function and fenofibric acid levels if possible.
- Bile Acid Sequestrants (e.g., Cholestyramine, Colestipol): May reduce absorption of fenofibric acid. Administer fenofibric acid at least 1 hour before or 4-6 hours after bile acid sequestrants.
Moderate Interactions
- Colchicine: Increased risk of myopathy/rhabdomyolysis when co-administered with fibrates, especially in patients with renal impairment.
- Oral Contraceptives: May alter lipid profiles, potentially reducing the effectiveness of fenofibric acid in some cases (though clinical significance is often minor).
Minor Interactions
- Not available
Monitoring
Baseline Monitoring
Rationale: To establish baseline lipid levels and assess the need for therapy.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline liver function, as fibrates can cause transaminase elevations and are contraindicated in active liver disease.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline renal function, as fenofibric acid is renally eliminated and dose adjustments are required in renal impairment.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline muscle enzyme levels, especially if patient has risk factors for myopathy or is on concomitant statin therapy.
Timing: Prior to initiation of therapy (optional, but recommended in high-risk patients).
Routine Monitoring
Frequency: Every 4-8 weeks initially, then every 6-12 months once stable.
Target: Individualized based on treatment goals (e.g., LDL-C < 100 mg/dL, Triglycerides < 150 mg/dL).
Action Threshold: If goals not met, consider dose adjustment or alternative therapy. If lipid levels worsen, investigate adherence or other factors.
Frequency: Every 3 months during the first year of treatment, then periodically (e.g., annually) thereafter.
Target: Within normal limits (e.g., < 3x ULN).
Action Threshold: If ALT or AST > 3x ULN, discontinue therapy. If elevations are persistent but < 3x ULN, monitor closely or consider dose reduction/discontinuation.
Frequency: Periodically (e.g., annually) or more frequently in patients with pre-existing renal impairment or risk factors.
Target: Stable, within acceptable limits for the patient.
Action Threshold: If eGFR decreases significantly or CrCl falls below 30 mL/min, discontinue therapy. If CrCl falls below 60 mL/min, consider dose reduction.
Frequency: As clinically indicated (e.g., if muscle symptoms develop, or if co-administered with statins).
Target: Within normal limits.
Action Threshold: If CK > 5x ULN, or if muscle symptoms are severe, discontinue therapy. If CK is elevated but < 5x ULN with mild symptoms, monitor closely.
Symptom Monitoring
- Unexplained muscle pain, tenderness, or weakness (especially if accompanied by fever or malaise)
- Dark urine
- Yellowing of skin or eyes (jaundice)
- Unusual fatigue or weakness
- Severe abdominal pain (may indicate pancreatitis or gallstones)
- Nausea or vomiting
- Loss of appetite
Special Patient Groups
Pregnancy
Category C. There are no adequate and well-controlled studies in pregnant women. Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Lipid-lowering drugs are generally considered unnecessary during pregnancy.
Trimester-Specific Risks:
Lactation
It is not known whether fenofibric acid is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Safety and effectiveness in pediatric patients have not been established. Use is generally not recommended.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. Due to the higher incidence of renal impairment in the elderly, dose selection should be cautious, and renal function should be monitored.
Clinical Information
Clinical Pearls
- Fenofibric acid DR capsules can be taken without regard to meals, which is a convenience advantage over some older fenofibrate formulations.
- Regular monitoring of liver function tests (LFTs) and renal function is crucial, especially during the first year of treatment and in patients with pre-existing conditions.
- Educate patients on the signs and symptoms of myopathy (muscle pain, weakness) and advise them to report these immediately, especially if they are also taking a statin.
- Fenofibric acid is primarily used for severe hypertriglyceridemia or mixed dyslipidemia, often when statins alone are insufficient or contraindicated.
- Patients on warfarin require very close INR monitoring and potential dose adjustments when initiating or discontinuing fenofibric acid.
- This formulation is the active metabolite, fenofibric acid, which means it bypasses the first-pass hydrolysis of fenofibrate.
Alternative Therapies
- Other fibrates (e.g., Gemfibrozil, Fenofibrate micronized/nanocrystallized)
- HMG-CoA reductase inhibitors (Statins, e.g., Atorvastatin, Rosuvastatin) - primary agents for LDL-C lowering
- Omega-3 Fatty Acid Esters (e.g., Icosapent ethyl, Omega-3-acid ethyl esters) - for severe hypertriglyceridemia
- PCSK9 Inhibitors (e.g., Alirocumab, Evolocumab) - for severe hypercholesterolemia
- Ezetimibe (Cholesterol absorption inhibitor)
- Bempedoic Acid (ATP Citrate Lyase inhibitor)
- Nicotinic Acid (Niacin) - less commonly used due to side effects
- Bile Acid Sequestrants (e.g., Cholestyramine, Colesevelam)
