Ezetimibe for Statin-Intolerant Hypercholesterolemia
Yes, you should absolutely prescribe Zetia (ezetimibe) 10 mg daily for this 65-year-old patient with statin intolerance—it is the guideline-recommended first-line non-statin therapy for LDL-C lowering. 1
Why Ezetimibe is the Right Choice
Ezetimibe is specifically recommended by the American College of Cardiology as first-line therapy for statin-intolerant patients due to its demonstrated safety, tolerability, and convenience. 1 The 2018 ACC/AHA guidelines explicitly state that in patients with LDL-C ≥100 mg/dL who cannot tolerate statins, ezetimibe therapy is reasonable. 2
Your patient's lipid profile shows:
- LDL-C 145 mg/dL (elevated, requiring treatment)
- Non-HDL-C 161 mg/dL (high-risk marker)
- Triglycerides 78 mg/dL (normal, no contraindication to any therapy)
- HDL-C 66 mg/dL (protective)
Expected Outcomes with Ezetimibe
- LDL-C reduction of 15-20% when used as monotherapy 1, 3
- This would lower her LDL-C from 145 mg/dL to approximately 116-123 mg/dL
- Non-HDL-C will also decrease by similar magnitude 4
- Ezetimibe is well-tolerated with minimal side effects, particularly no muscle-related adverse effects like statins 3
FDA-Approved Indications Match This Patient
The FDA label confirms ezetimibe is indicated "alone (when additional cholesterol lowering treatments are not possible), to lower elevated low-density lipoprotein cholesterol (LDL-C) or bad cholesterol in adults with primary hyperlipidemia." 5 Your patient's statin intolerance (sharp foot pain) qualifies as a situation where "additional cholesterol lowering treatments are not possible."
Practical Prescribing Details
- Dose: Ezetimibe 10 mg once daily 5
- Timing: Can be taken with or without food, at any time of day 5
- No dose adjustment needed for her age (65 years) or normal renal function 5
- Recheck lipid panel in 4-12 weeks to assess response 2, 1
What Happens If Ezetimibe Alone is Insufficient
If her LDL-C remains elevated after 8-12 weeks on ezetimibe:
- Add bempedoic acid 180 mg daily as the next step, which provides an additional 15-25% LDL-C reduction 6
- Consider PCSK9 inhibitor (like Repatha) if she has very high cardiovascular risk and LDL-C remains ≥70 mg/dL despite ezetimibe + bempedoic acid 6
- Bile acid sequestrants (colesevelam) are a third-line option since her triglycerides are <300 mg/dL, but they are less preferred due to tolerability issues 2, 1
Addressing the Insurance Issue with Repatha
While Repatha (evolocumab) would provide superior LDL-C lowering (~50-60% reduction), guidelines explicitly recommend trying ezetimibe first before escalating to PCSK9 inhibitors due to cost-effectiveness considerations. 1, 6 Insurance companies typically require documentation of inadequate response to ezetimibe (and often bempedoic acid) before approving PCSK9 inhibitors.
Risk Stratification Context
With a calcium score of 17% (assuming this means 17th percentile or Agatston score of 17), she has mild coronary atherosclerosis, placing her at moderate-to-high cardiovascular risk. 2 The American Diabetes Association guidelines suggest that for patients with 10-year ASCVD risk ≥20%, it may be reasonable to add ezetimibe to maximally tolerated statin therapy—in her case, since she cannot tolerate statins at all, ezetimibe monotherapy is the appropriate starting point. 2
Common Pitfalls to Avoid
- Do not skip ezetimibe and go straight to PCSK9 inhibitors—this violates guideline recommendations and will likely result in insurance denial 1
- Do not use bile acid sequestrants as first-line—they have more GI side effects and are less convenient than ezetimibe 1
- Do not forget to continue lifestyle modifications—the dietary changes you've already discussed (avoiding saturated/trans fats, increasing omega-3s) remain essential 1
- Do not use ezetimibe with statins if she truly cannot tolerate any statin—the FDA label warns against combining with statins if the patient has been told not to take them 5
