Medications for Hyperlipidemia (High Cholesterol)
ICD-10: E78.5
Key Takeaways
- Statins are the cornerstone of hyperlipidemia treatment — they reduce LDL cholesterol by 30–55% and cardiovascular events by 25–35%.
- Ezetimibe (Zetia) is the most commonly added non-statin agent — it reduces LDL by an additional 15–20% and is available as a low-cost generic.
- PCSK9 inhibitors (evolocumab, alirocumab) reduce LDL by 50–60% on top of statins and are indicated for very high-risk patients or familial hypercholesterolemia.
- Triglyceride-lowering medications (fibrates, omega-3 fatty acids) are used when triglycerides exceed 500 mg/dL or for residual cardiovascular risk.
- Inclisiran (Leqvio) is a twice-yearly injectable siRNA that reduces LDL by ~50% — a new option for patients with adherence challenges.
Overview
Hyperlipidemia, often called high cholesterol, means you have too much fat-like substance (cholesterol) and other fats (triglycerides) in your blood. It's very common, affecting millions of adults, and often has no symptoms until it causes serious problems. If left untreated, high cholesterol can lead to heart disease, heart attacks, and strokes, making it a major health concern.
Treatment Overview
Treating high cholesterol usually starts with lifestyle changes like eating healthier, exercising regularly, and maintaining a healthy weight. If these changes aren't enough, doctors often prescribe medications like statins to lower cholesterol levels. In some cases, especially for very high levels or specific types of hyperlipidemia, a specialist like a cardiologist may be involved to create a personalized treatment plan.

Drug Classes for Hyperlipidemia (High Cholesterol)
Pharmacist-reviewed overview of each medication class, how it works, and when it's used.
Statins (HMG-CoA Reductase Inhibitors)
Statins
Mechanism of Action
Inhibit HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis. Reduced intracellular cholesterol triggers upregulation of LDL receptors on hepatocytes, increasing LDL clearance from the bloodstream.
Common Examples
Clinical Notes
High-intensity statins (atorvastatin 40–80 mg, rosuvastatin 20–40 mg) reduce LDL by ≥50% and are recommended for high-risk patients. Moderate-intensity statins reduce LDL by 30–50%. All major statins are available as generics.
Common Side Effects
- Myalgia (muscle aches) — 5–10%
- Elevated liver enzymes — 1–3%
- New-onset diabetes — small increased risk
- Rhabdomyolysis — rare but serious
Cholesterol Absorption Inhibitors
Ezetimibe
Mechanism of Action
Inhibits the Niemann-Pick C1-like 1 (NPC1L1) transporter in the small intestine, blocking absorption of dietary and biliary cholesterol. Reduces LDL by 15–20% as monotherapy; 15–20% additional reduction when added to a statin.
Common Examples
Clinical Notes
The IMPROVE-IT trial showed that adding ezetimibe to simvastatin reduced cardiovascular events by an additional 6.4% in post-ACS patients. Now available as a generic — very cost-effective add-on to statin therapy.
Common Side Effects
- Generally well tolerated
- Diarrhea
- Myalgia (when combined with statin)
- Elevated liver enzymes (rare)
PCSK9 Inhibitors
PCSK9i
Mechanism of Action
Monoclonal antibodies that inhibit PCSK9, a protein that degrades LDL receptors. By blocking PCSK9, more LDL receptors remain on hepatocytes, dramatically increasing LDL clearance.
Common Examples
Clinical Notes
Reduce LDL by 50–60% on top of maximally tolerated statin therapy. FDA-approved for established ASCVD, familial hypercholesterolemia, and statin intolerance. Administered subcutaneously every 2–4 weeks. High cost ($500–600/month) limits use; prior authorization typically required.
Common Side Effects
- Injection site reactions
- Nasopharyngitis
- Generally very well tolerated
Bile Acid Sequestrants
Resins
Mechanism of Action
Bind bile acids in the intestine, preventing their reabsorption. The liver must synthesize new bile acids from cholesterol, depleting hepatic cholesterol and upregulating LDL receptors.
Common Examples
Clinical Notes
Reduce LDL by 15–30%. Colesevelam is the best-tolerated and also FDA-approved for type 2 diabetes (reduces HbA1c). Useful in pregnancy (not absorbed systemically). Can impair absorption of other medications — take other drugs 1 hour before or 4 hours after.
Common Side Effects
- Constipation
- Bloating and flatulence
- Elevated triglycerides
- Drug interactions (impairs absorption of warfarin, thyroid hormones, digoxin)
Fibrates
Fibrates
Mechanism of Action
Activate peroxisome proliferator-activated receptor alpha (PPARα), increasing lipoprotein lipase activity and reducing hepatic VLDL production. Primarily lower triglycerides (40–60%) and raise HDL (10–20%).
Common Examples
Clinical Notes
Primary indication is hypertriglyceridemia (TG >500 mg/dL) to prevent pancreatitis. Avoid combining gemfibrozil with statins (increased myopathy risk). Fenofibrate is safer with statins than gemfibrozil.
Common Side Effects
- Myopathy (especially with statins)
- Elevated creatinine
- Gallstones
- GI upset

First-Line Medications
Simvastatin
(Simvastatin)First-LineSimvastatin (Zocor) is a type of medicine called a statin, primarily used to lower high cholesterol and triglyceride levels in the blood. By reducing "bad" cholesterol and increasing "good" cholesterol, it helps decrease your risk of heart attack, stroke, and other heart-related problems. It works by blocking an enzyme in your liver that makes cholesterol.
Lovastatin
(Lovastatin)First-LineLOVASTATIN (brand name: Lovastatin) is a statin (HMG-CoA reductase inhibitor). Indications and Usage Therapy with lovastatin should be a component of multiple risk factor intervention in those individuals with dyslipidemia at risk for atherosclerotic vascular disease. Lovastatin should be used in addition to a diet restricted in saturated fat and cholesterol as part of a…
Atorvastatin
(Lipitor)First-LineAtorvastatin (Lipitor) is the world's best-selling prescription drug and the most widely prescribed statin for lowering LDL ('bad') cholesterol and reducing the risk of heart attack, stroke, and cardiovascular death. It is used for both primary prevention (in people without established heart disease but with risk factors) and secondary prevention (in people who have already had a heart attack or stroke). Generic atorvastatin is available for as little as $4–$25 per month.
Generic Available
Rosuvastatin
(Rosuvastatin Calcium)First-LineRosuvastatin is a medication in a class called "statins" that helps lower high cholesterol and other fats in your blood. It works by reducing the amount of "bad" cholesterol your body makes, which helps to prevent heart problems and slow the progression of hardening of the arteries.
Pravastatin
(Pravastatin Sodium)First-LinePravastatin is a statin medication used to lower high levels of "bad" cholesterol (LDL-C) in the blood. By reducing cholesterol production in the liver, it helps decrease the risk of serious heart problems like heart attacks and strokes. It is typically used along with a healthy diet.
Fluvastatin
(Fluvastatin)First-LineFluvastatin (brand names: Fluvastatin, Fluvastatin Sodium) is a type of medicine called a statin. It is primarily used to help lower high levels of "bad" cholesterol (like LDL-C) and fats (triglycerides) in the blood, and to increase "good" cholesterol (HDL-C), especially when diet and exercise alone aren't enough. It works by reducing the amount of cholesterol your body makes.
Pitavastatin
(Pitavastatin)First-LinePitavastatin is a "statin" medication used to lower high cholesterol levels in your blood. It works by reducing the amount of "bad" cholesterol (LDL-C) your body makes, helping to improve your overall cholesterol profile, especially in adults and children aged 8 and older with certain types of high cholesterol. This medicine is always used along with a healthy diet.
How to Choose the Right Medication
Clinical decision factors used by prescribers when selecting a treatment.
- 1For all patients with hyperlipidemia: start with a statin at the appropriate intensity based on cardiovascular risk (see ACC/AHA guidelines).
- 2If LDL target not met on maximum tolerated statin: add ezetimibe first — it is inexpensive, well-tolerated, and has proven cardiovascular outcome data.
- 3If LDL still not at target on statin + ezetimibe, or for familial hypercholesterolemia: add a PCSK9 inhibitor.
- 4For hypertriglyceridemia >500 mg/dL (pancreatitis risk): add a fibrate or high-dose omega-3 fatty acids (icosapentaenoic acid — Vascepa).
- 5For statin-intolerant patients: try a different statin at a lower dose, or switch to rosuvastatin (often better tolerated). If truly statin-intolerant: ezetimibe + PCSK9 inhibitor.
- 6For patients with adherence challenges: inclisiran (twice-yearly injection) may improve long-term adherence.
Monitoring & Follow-Up
- Check a fasting lipid panel 4–12 weeks after starting or changing therapy to assess response.
- Check liver enzymes (ALT/AST) at baseline; routine monitoring during statin therapy is not required unless symptomatic.
- Check CK (creatine kinase) if muscle symptoms develop — do not check routinely.
- Monitor for new-onset diabetes in patients on high-intensity statins, particularly those with prediabetes or metabolic syndrome.
- Annual lipid panel for patients on stable therapy.

Frequently Asked Questions
What is hyperlipidemia (high cholesterol)?
Hyperlipidemia means you have too much cholesterol and other fats, called triglycerides, in your blood. Cholesterol is a waxy substance your body needs to build healthy cells, but too much can cause problems. It can build up in your arteries, making them narrow and hard, which increases your risk for heart disease.
What causes high cholesterol?
High cholesterol can be caused by many things. Eating foods high in saturated and trans fats, not getting enough exercise, and being overweight are common causes. Genetics can also play a big role, meaning it can run in families. Other conditions like diabetes, kidney disease, and an underactive thyroid can also contribute.
How is high cholesterol diagnosed?
High cholesterol is diagnosed with a simple blood test called a lipid panel or lipid profile. This test measures your total cholesterol, LDL ('bad') cholesterol, HDL ('good') cholesterol, and triglycerides. You usually need to fast (not eat or drink anything but water) for 9-12 hours before the test for the most accurate results.
What are the treatment options for high cholesterol?
Treatment for high cholesterol often begins with lifestyle changes like eating a heart-healthy diet, regular exercise, losing weight if needed, and quitting smoking. If these aren't enough, your doctor might prescribe medications such as statins (like simvastatin, atorvastatin, rosuvastatin), which are very effective at lowering cholesterol. Other medications may also be used depending on your specific needs.
Can high cholesterol be cured?
High cholesterol is usually a lifelong condition that needs ongoing management rather than a 'cure.' While you can significantly lower your cholesterol levels and reduce your health risks through lifestyle changes and medication, it often requires continuous effort. If you stop treatment, your cholesterol levels may rise again.
How can I manage high cholesterol day-to-day?
Managing high cholesterol daily involves making healthy choices. This includes eating a balanced diet rich in fruits, vegetables, and whole grains, and low in saturated and trans fats. Regular physical activity, maintaining a healthy weight, and taking your prescribed medications exactly as directed are also crucial. Regular check-ups with your doctor are important to monitor your levels and adjust your treatment plan if needed.
Do statins cause memory loss or dementia?
The evidence does not support a causal link between statins and dementia. The FDA added a label warning about 'cognitive impairment' in 2012 based on post-marketing reports, but large observational studies and randomized trials have not found a significant association. Some studies actually suggest statins may reduce dementia risk. The cognitive effects reported are generally mild, reversible upon stopping the statin, and not associated with long-term cognitive decline.
Can I lower my cholesterol without medication?
Lifestyle changes can reduce LDL by 20–30% in motivated patients: a diet low in saturated fat and trans fat, high in soluble fiber (oats, beans, psyllium), and including plant sterols/stanols can reduce LDL by 10–20%. Regular aerobic exercise raises HDL and lowers triglycerides. However, for patients with established cardiovascular disease or familial hypercholesterolemia, lifestyle changes alone are rarely sufficient — statins are indicated regardless of diet and exercise.
