What are the treatment options for hypertriglyceridemia?

Treatment Options to Reduce Triglyceride Levels

Immediate Treatment Based on Triglyceride Severity

The treatment approach depends entirely on your fasting triglyceride level, with severe elevations requiring immediate pharmacologic intervention to prevent life-threatening pancreatitis, while moderate elevations focus on cardiovascular risk reduction.

Severe to Very Severe Hypertriglyceridemia (≥500 mg/dL)

Start fenofibrate 54-160 mg daily immediately—this is mandatory regardless of your LDL cholesterol or cardiovascular risk, because triglycerides at this level carry a 14% risk of acute pancreatitis. 1, 2 Fenofibrate will reduce your triglycerides by 30-50%, which is essential for preventing this life-threatening complication. 1, 3

• Do not start with statin monotherapy at this level; statins only lower triglycerides by 10-30%, which is insufficient to prevent pancreatitis. 1, 2
• Once your triglycerides fall below 500 mg/dL with fenofibrate, your doctor should reassess your LDL cholesterol and add a statin if it's elevated or if you have high cardiovascular risk. 1, 2

Critical dietary changes you must implement immediately:

• Restrict total dietary fat to 20-25% of calories for triglycerides 500-999 mg/dL, or to 10-15% (or even <5% until levels drop below 1,000 mg/dL) for very severe cases. 1, 2, 4
• Eliminate all added sugars completely—sugar directly increases your liver's triglyceride production. 1, 2, 4
• Zero alcohol consumption—even 1 ounce daily raises triglycerides by 5-10%, and alcohol can trigger hypertriglyceridemic pancreatitis at these levels. 1, 2, 4

Moderate Hypertriglyceridemia (200-499 mg/dL)

If you have diabetes (age 40-75), a 10-year cardiovascular disease risk ≥7.5%, or established heart disease, start a moderate-to-high intensity statin immediately (atorvastatin 10-20 mg or rosuvastatin 5-10 mg daily) alongside lifestyle changes—do not delay medication while only trying lifestyle modifications. 1, 2, 3

Statins provide:

• 10-30% triglyceride reduction (dose-dependent) 1, 2, 3
• Proven cardiovascular mortality benefit through LDL cholesterol lowering 1, 2, 5
• The strongest evidence base of any lipid-lowering therapy 1, 5

Your lipid targets while on statin therapy:

• LDL cholesterol <100 mg/dL (or <70 mg/dL if very high-risk) 1, 2
• Non-HDL cholesterol <130 mg/dL 1, 2
• Triglycerides <200 mg/dL (ideally <150 mg/dL) 1, 2, 3

If triglycerides remain >200 mg/dL after 3 months of optimized lifestyle changes and statin therapy:

• First choice: Add icosapent ethyl (prescription EPA) 2 g twice daily if you have established cardiovascular disease OR diabetes with ≥2 additional risk factors (hypertension, smoking, family history, age >50 years men/>60 years women, chronic kidney disease). 1, 2, 3

  • This is the only triglyceride-lowering drug FDA-approved for cardiovascular risk reduction. 1, 2
  • The REDUCE-IT trial showed a 25% reduction in major cardiovascular events (number needed to treat = 21). 1, 2, 5
  • Monitor for atrial fibrillation (occurs in 3.1% vs 2.1% with placebo). 1, 2, 3

• Alternative: Add fenofibrate 54-160 mg daily if you don't meet the icosapent ethyl criteria but triglycerides stay >200 mg/dL. 1, 2, 3

  • Provides 30-50% triglyceride reduction. 1, 2, 3
  • When combined with statins, use fenofibrate (NOT gemfibrozil) because fenofibrate has a much better safety profile—gemfibrozil significantly increases myopathy risk. 1, 2, 3
  • Your doctor may reduce your statin dose (atorvastatin ≤20 mg or rosuvastatin ≤10 mg) if you're >65 years or have kidney disease to minimize muscle problems. 1, 2, 3

Mild Hypertriglyceridemia (150-199 mg/dL)

If you have a 10-year cardiovascular risk ≥7.5% or diabetes (age 40-75), consider starting a moderate-intensity statin because persistent triglycerides ≥175 mg/dL are a cardiovascular risk-enhancing factor. 1, 2

If your cardiovascular risk is lower, focus exclusively on intensive lifestyle modifications for at least 3 months before considering any medication. 1, 2

Essential Lifestyle Modifications (For All Triglyceride Levels)

Weight loss is the single most effective lifestyle intervention—a 5-10% reduction in body weight produces a 20% decrease in triglycerides, and some people achieve 50-70% reductions with weight loss alone. 1, 2, 4

Dietary Changes by Severity:

For mild-moderate hypertriglyceridemia (150-499 mg/dL):

• Limit added sugars to <6% of total daily calories (approximately 30 grams on a 2,000-calorie diet). 1, 2, 3
• Keep total dietary fat at 30-35% of calories. 1, 2, 3
• Restrict saturated fat to <7% of calories and replace with monounsaturated or polyunsaturated fats (olive oil, nuts, avocado, fatty fish). 1, 2, 3
• Eliminate trans fats completely. 1, 2
• Increase soluble fiber to >10 g/day from oats, beans, lentils, vegetables. 1, 2, 3
• Eat ≥2 servings per week of fatty fish (salmon, trout, sardines, mackerel). 1, 2

For severe hypertriglyceridemia (≥500 mg/dL):

• See the more restrictive dietary requirements listed above in the severe hypertriglyceridemia section. 1, 2, 4

Physical Activity:

Engage in ≥150 minutes/week of moderate-intensity aerobic exercise (or 75 minutes/week vigorous activity)—this reduces triglycerides by approximately 11%. 1, 2, 3, 4

Alcohol:

Limit or completely avoid alcohol; even modest intake (1 ounce daily) raises triglycerides by 5-10%, and complete abstinence is mandatory when levels approach or exceed 500 mg/dL. 1, 2, 3

Address Secondary Causes First

Before starting any triglyceride-lowering medication, your doctor must evaluate and treat these common contributors, which can lower triglycerides by 20-50% independent of drugs:

• Uncontrolled diabetes: Optimizing blood sugar control is often more effective than additional lipid medications for severe hypertriglyceridemia. 1, 2, 6
• Hypothyroidism: Must be treated before expecting full response to lipid therapy. 1, 2, 7
• Medications that raise triglycerides: Thiazide diuretics, beta-blockers, oral estrogen, corticosteroids, antiretrovirals, atypical antipsychotics—discontinue or substitute when possible. 1, 2, 6
• Chronic kidney or liver disease: Contributes to hypertriglyceridemia and affects medication dosing. 1, 2, 6

Critical Pitfalls to Avoid

• Do not delay fenofibrate when triglycerides ≥500 mg/dL; pharmacologic therapy is mandatory to prevent pancreatitis. 1, 2, 3
• Do not postpone statin initiation in high-risk patients (cardiovascular risk ≥7.5%, diabetes, established heart disease) while only trying lifestyle changes—both should start together. 1, 2
• Do not use gemfibrozil with statins; fenofibrate has a markedly better safety profile. 1, 2, 3
• Do not rely on over-the-counter fish oil supplements for cardiovascular benefit; only prescription icosapent ethyl has proven outcome data. 1, 2
• Do not discontinue statins in favor of fibrate monotherapy if you have cardiovascular risk or established disease; statins provide proven mortality benefit. 1, 2

Monitoring Strategy

• Recheck fasting lipid panel 6-12 weeks after starting lifestyle changes. 1, 2
• Recheck lipids 4-8 weeks after starting or adjusting any medication. 1, 2, 3
• If on fenofibrate, monitor kidney function at baseline, 3 months, then every 6 months. 1, 2
• If combining fenofibrate with a statin, monitor for muscle symptoms and check creatine kinase levels, especially if >65 years or have kidney disease. 1, 2, 3
