Hyperlipidemia:
Children 5 to 8 years: Limited data available: Oral: 10 mg once daily; dosing based on two studies of monotherapy; a prospective trial (n=17 including six patients ≤9 years) and a retrospective review (n=36, age range: 8 to 17 years) showed significant decreases in total cholesterol and LDL-C; patients were followed up to a mean of 13.6 months, no untoward effects were noted (Ref).
Children ≥9 years and Adolescents: Oral: 10 mg once daily in combination with a statin and other LDL-C lowering therapies. Has also been shown in small pediatric trials to decrease total cholesterol and LDL-C when used as monotherapy as adjunct to dietary changes (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Hyperlipidemia:
Children ≥9 years and Adolescents: No dosage adjustments are recommended.
Hyperlipidemia:
Children ≥9 years and Adolescents:
Mild hepatic impairment: No dosage adjustments are recommended.
Moderate to severe impairment: Use is not recommended; the effects of increased ezetimibe exposure are unknown.
Increased serum transaminases and hepatotoxicity have been associated with ezetimibe. A higher incidence of elevated transaminases (≥3 × ULN) has been observed with concurrent use of ezetimibe with statins compared to statin monotherapy (Ref). Acute liver injury, ranging from hepatocellular hepatitis to cholestatic hepatitis, has been reported (Ref). Autoimmune hepatitis-like syndrome has also been described (Ref). Since ezetimibe is frequently administered with other lipid-lowering agents, especially statins, it is difficult to assess the role of ezetimibe in causality of hepatotoxicity. If elevated transaminase levels do occur, they will often return to baseline with or without discontinuation of therapy. In patients with severe hepatotoxicity, resolution of symptoms usually occurs within 1 to 4 months (Ref).
Mechanism: Non–dose-related; unknown. Conjugation defect may lead to accumulation of toxic levels of ezetimibe in the liver in genetically predisposed patients (Ref). An immune-mediated response may be implicated in cases of autoimmune hepatitis-like syndrome (Ref).
Onset: Delayed; ranged from 1 to 6 months (Ref).
Risk factors:
• Concurrent use of statins (Ref)
• Preexisting hepatic impairment (not recommended in patients with moderate [Child-Pugh score 7 to 9] or severe [Child-Pugh score 10 to 15] hepatic impairment)
Ezetimibe, when used alone or in combination with statin therapy, has been linked to several muscle-related effects, including myalgia (Ref), myopathy (Ref), and rhabdomyolysis (Ref). Creatine kinase levels often normalize within 4 weeks of discontinuation of ezetimibe (Ref). Since ezetimibe is frequently co-administered with statins, which are commonly associated with muscle-related adverse effects, it is difficult to assess causality in many cases (Ref).
Mechanism: Unknown; impaired fatty acid oxidation may lead to ezetimibe-induced muscle related effects (Ref).
Onset: Varied; can present hours to 4 months, with most symptoms developing within 2 weeks (Ref).
Risk factors:
• Concurrent use of a statin or fibrate
• Preexisting muscle disease (eg, McArdle disease) (Ref)
• Risk factors for muscle-related effects with statins (eg, older adults, hypothyroidism, kidney impairment)

Adverse events were observed in some animal reproduction studies.
Outcome data following maternal use of ezetimibe during pregnancy are limited (Vuignier 2021).
If lipid-lowering therapy during pregnancy is required, it should be individualized based on the therapeutic needs of the patient, considering the lifetime risk of untreated disease, and the known risks and benefits of available therapies (CCS [Pearson 2021]).
Ezetimibe is present in breast milk.
Data are available from a study that developed an assay to measure ezetimibe in breast milk. Breast milk was sampled from 2 lactating patients taking ezetimibe 10 mg once daily. Ten samples were provided from 1 patient (21.8 weeks' postpartum) and 5 samples provided by a second patient (20.4 weeks' postpartum). Ezetimibe breast milk concentrations ranged from 0.17 to 1.02 ng/mL. The active glucuronide metabolite was also present (0.42 to 2.65 ng/mL). Authors of the study calculated the relative infant dose (RID) of ezetimibe to be 0.062%. Using a pharmacokinetic model, exposure to ezetimibe via breast milk was predicted to be below therapeutic doses (Yeung 2024). In general, breastfeeding is considered acceptable when the RID of a medication is <10% (Anderson 2016; Ito 2000).
Breastfeeding is not recommended by the manufacturer unless the potential benefits of treatment to the mother outweigh the possible risk to the breastfed infant. Effects to the breastfed infant or milk production are unknown.
Before initiation of therapy, patients should be placed on a standard cholesterol-lowering diet for 6 weeks and the diet should be continued during drug therapy.
Signs or symptoms of myopathy, CPK.
American College of Cardiology/American Heart Association blood cholesterol guideline recommendations (ACC/AHA [Grundy 2019]):
Lipid panel (total cholesterol, HDL-C, LDL-C, triglycerides): Lipid profile (fasting or nonfasting) before initiating treatment. Fasting lipid profile should be rechecked 4 to 12 weeks after starting therapy and every 3 to 12 months thereafter (AHA/ACC [Grundy 2019]).
Hepatic transaminase levels: Baseline LFTs (reasonable); when used in combination with statin therapy, monitor LFTs when clinically indicated. When used in combination with fenofibrate, monitor LFTs and signs and symptoms of cholelithiasis.
Inhibits absorption of cholesterol at the brush border of the small intestine via the sterol transporter, Niemann-Pick C1-Like1 (NPC1L1). This leads to a decreased delivery of cholesterol to the liver, reduction of hepatic cholesterol stores and an increased clearance of cholesterol from the blood; decreases total C, LDL-cholesterol (LDL-C), ApoB, and triglycerides (TG) while increasing HDL-cholesterol (HDL-C).
Note: Pharmacokinetic data in children and adolescents ≥10 years of age are reported to be similar to that in adult patients.
Onset of action: Within 1 week; Maximum effect: 2 to 4 weeks.
Protein binding: >90% to plasma proteins.
Metabolism: Undergoes glucuronide conjugation in the small intestine and liver; forms metabolite (active); may undergo enterohepatic recycling.
Half-life elimination: 22 hours (ezetimibe and metabolite).
Time to peak, plasma: 4-12 hours (ezetimibe); 1-2 hours (active metabolite); Effects: ~2 weeks.
Excretion: Feces (78%, 69% as ezetimibe); urine (11%, 9% as metabolite).
Altered kidney function: Severe renal dysfunction (CrCl <30 mL/minute/1.73 m2): AUC increased 1.5 times.
Hepatic impairment: Moderate hepatic impairment (Child-Pugh score 7 to 9): AUC increased 3 to 4 times; severe hepatic impairment (Child-Pugh 10 to 15): AUC increased 5 to 6 times.
Older adult: Plasma concentrations are approximately 2-fold higher.
Sex: Plasma concentrations for total ezetimibe were slightly higher (less than 20%) in women than in men.
