Fenofibrate: Uses, Dosage, Side Effects & Precautions

Fenofibrate is a fibrate medicine used along with diet to lower high triglycerides and, in some adults, high cholesterol. This guide covers fenofibrate uses, how it works, dosage, side effects, precautions, drug interactions, use in pregnancy and breastfeeding and its approximate price in India.

What Is Fenofibrate?

Fenofibrate is a fibric acid derivative (fibrate) used along with a lipid-lowering diet to lower high triglycerides and, in some adults, high cholesterol. It is prescribed for adults with hypertriglyceridemia, primary hypercholesterolemia or mixed dyslipidemia, and may sometimes be combined with other cholesterol-lowering medicines, such as statins, under a doctor’s guidance.

How Fenofibrate Works

Fenofibrate activates PPAR-alpha receptors, which increases the activity of lipoprotein lipase (LPL), an enzyme that helps break down and clear triglyceride-rich particles from the blood. It also raises HDL (“good”) cholesterol. Raising HDL or lowering triglycerides has not on its own been shown to reduce heart attacks or deaths, so these lab changes should not be read as proven protection against heart disease.

When to Use Fenofibrate

• Severe hypertriglyceridemia: Lowers very high triglyceride levels. Markedly high triglycerides (for example above 2,000 mg/dL) may increase the risk of pancreatitis, but the effect of fenofibrate on reducing this risk has not been adequately studied.
• Primary hypercholesterolemia or mixed dyslipidemia: Helps lower LDL and total cholesterol and triglycerides, and raises HDL, alongside diet.

Fenofibrate was not shown to reduce heart attacks or deaths from heart disease in a large trial of people with type 2 diabetes. Your doctor will decide whether it suits your lipid profile and overall risk.

Fenofibrate Dosage

Fenofibrate doses vary by formulation and strength and are not interchangeable on a milligram-for-milligram basis. Follow the exact product and dose prescribed by your doctor.

• Example from US prescribing information for fenofibrate 145 mg tablets: The initial dose for primary hypercholesterolemia or mixed dyslipidemia is 145 mg once daily. For severe hypertriglyceridemia, the starting dose is 48–145 mg daily, adjusted according to blood tests, with a maximum of 145 mg once daily. These tablets can be taken without regard to meals. This applies only to that product and not to other strengths or capsules.
• Other strengths and forms: Other tablets (for example 105 mg or 160 mg) and capsules (for example 200 mg) have their own dosing and food instructions. Some Indian product information advises taking fenofibrate with food, so follow the instructions for your specific product.
• Kidney problems: For the 145 mg tablets, a starting dose of 48 mg daily is advised in mild to moderate kidney impairment, increased only after kidney function and lipid levels are checked. Fenofibrate should be avoided in severe kidney impairment. Renal dosing varies by product, so the dose must follow your product’s information.
• Older adults: Dose is chosen according to kidney function, not age alone, and kidney function may be monitored.
• Liver disease: Fenofibrate is not suitable for people with active liver disease.
• Children: For the fenofibrate products reviewed, safety and effectiveness have not been established in children.

Keep following your lipid-lowering diet while taking fenofibrate. Do not change or stop the dose on your own.

Monitoring

Your doctor may check lipid levels to see how well treatment is working. Depending on your situation, your doctor may also check liver enzymes (ALT, AST), kidney function or serum creatinine, and CK/CPK if you develop muscle symptoms or have risk factors. Not every patient needs every test at every visit.

Side Effects of Fenofibrate

Common: Abdominal pain, nausea, vomiting, diarrhea, gas, headache, back pain, a runny or inflamed nose, and raised liver enzymes or CPK on blood tests.

Serious (less common) problems that need prompt medical attention:

• Liver injury: Yellowing of the skin or eyes, dark urine, unusual tiredness or loss of appetite
• Muscle problems: Unexplained muscle pain, tenderness, cramps or weakness, especially with dark urine or fever. This can be a sign of myopathy or rhabdomyolysis and needs urgent review, especially if you also take a statin.
• Gallbladder disease or pancreatitis: Severe stomach pain, with or without nausea or vomiting
• Serious skin reactions: Severe rash, blistering or peeling
• Blood clots (reported with fenofibrate): Swelling or pain in a leg, sudden chest pain or breathlessness

Who Should Not Use Fenofibrate

Depending on the product, fenofibrate is generally not suitable for people with severe kidney disease (including those on dialysis), active liver disease, gallbladder disease, or a known allergy to fenofibrate or fenofibric acid. Tell your doctor about any kidney, liver or gallbladder condition, and about any history of muscle problems.

Fenofibrate Drug Interactions

• Statins: The risk of muscle problems is higher when a statin is used with fenofibrate. Doctors combine them only when the benefit is likely to outweigh the risk.
• Colchicine: Muscle problems, including rhabdomyolysis, have been reported with colchicine and fibrates.
• Warfarin and similar blood thinners (coumarins): Fenofibrate can increase their effect, so closer monitoring may be needed.
• Bile acid resins (such as colestyramine): Take fenofibrate at least 1 hour before, or 4 to 6 hours after, the resin.
• Ciclosporin and tacrolimus: These can affect the kidneys, and combining them with fenofibrate may worsen kidney function, so your doctor may monitor it.

Tell your doctor or pharmacist about all medicines and supplements you use. This is not a complete list.

Fenofibrate in Pregnancy and Breastfeeding

Available data on fenofibrate in pregnancy are limited and insufficient to determine the risk of birth defects or miscarriage. Prescribing information advises using it during pregnancy only if the potential benefit justifies the potential risk, so it is not a routine treatment in pregnancy. If you are pregnant or planning pregnancy, discuss treatment with a qualified healthcare professional.

No published information exists on its use during breastfeeding, and the US Drugs and Lactation Database (LactMed) says it is best avoided because of a concern about disruption of infant lipid metabolism. The manufacturer recommends avoiding breastfeeding during treatment and for 5 days after the final dose. Talk to your doctor about alternatives if you are breastfeeding.
