Liptruzet (ezetimibe/atorvastatin) is a combination of a cholesterol blocker and a statin used to reduce cholesterol. Common side effects of Liptruzet include

Liptruzet is dosed as 10/10 (ezetimibe/atorvastatin) mg per day through 10/80 mg per day, with the recommended starting dose of 10/10 mg per day or 10/20 mg per day. Liptruzet may interact with antibiotics, medications prescribed for HIV/AIDS, other statins, and some oral contraceptives. Patients who are allergic or sensitive to ezetimibe and/or atorvastatin should not take Liptruzet. Liptruzet should not be used by women who are pregnant or may become pregnant as it may cause fetal harm. It is not known whether atorvastatin (a component of Liptruzet) is excreted into human milk. Another drug in this class passes into breast milk. Because statins have the potential for serious adverse reactions in nursing infants, breastfeeding is not recommended.

Liptruzet FDA Prescribing Information: Side Effects
(Adverse Reactions)


The following serious adverse reactions are discussed in greater detail in other sections of the label:

Clinical Trials Experience


Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.

In a LIPTRUZET (ezetimibe and atorvastatin) placebo-controlled clinical trial, 628 patients (age range 18-86 years, 59% women, 85% Caucasians, 6% Blacks, 5% Hispanics, 3% Asians) with a median treatment duration of 12 weeks, 6% of patients on LIPTRUZET and 5% of patients on placebo discontinued due to adverse reactions.

The most common adverse reactions in the group treated with LIPTRUZET that led to treatment discontinuation and occurred at a rate greater than placebo were:

  • Myalgia (0.8%)
  • Abdominal pain (0.8%)
  • Increased hepatic enzymes (0.8%)

The most commonly reported adverse reactions (incidence ≥ 2% and greater than placebo) in this trial were: increased ALT (5%), increased AST (4%), and musculoskeletal pain (4%).

LIPTRUZET has been evaluated for safety in 2403 patients in 7 clinical trials (one placebo-controlled trial and six active-controlled trials).

Table 2 summarizes the frequency of clinical adverse reactions reported in ≥ 2% of patients treated with LIPTRUZET (n=255) and at an incidence greater than placebo, regardless of causality assessment, from the placebo-controlled trial.

* Placebo-controlled combination study in which the active ingredients equivalent to LIPTRUZET were coadministered.
† All doses.

After completing the 12-week study, eligible patients were assigned to coadministered ezetimibe and atorvastatin equivalent to LIPTRUZET (10/10-10/80) or atorvastatin (10-80 mg/day) for an additional 48 weeks. The long-term coadministration of ezetimibe plus atorvastatin had an overall safety profile similar to that of atorvastatin alone.


In 10 double-blind, placebo-controlled clinical trials, 2396 patients with primary hyperlipidemia (age range 9-86 years, 50% women, 90% Caucasians, 5% Blacks, 3% Hispanics, 2% Asians) and elevated LDL-C were treated with ezetimibe 10 mg/day for a median treatment duration of 12 weeks (range 0 to 39 weeks).

Adverse reactions reported in ≥ 2% of patients treated with ezetimibe and at an incidence greater than placebo regardless of causality assessment are shown in Table 3.

In an atorvastatin placebo-controlled clinical trial database of 16,066 patients (8755 atorvastatin vs. 7311 placebo; age range 10-93 years, 39% women, 91% Caucasians, 3% Blacks, 2% Asians, 4% other) with a median treatment duration of 53 weeks, 9.7% of patients on atorvastatin and 9.5% of the patients on placebo discontinued due to adverse reactions regardless of causality.

The most commonly reported adverse reactions (incidence ≥ 2% and greater than placebo) regardless of causality, in patients treated with atorvastatin in placebo controlled trials (n=8755) were: nasopharyngitis (8.3%), arthralgia (6.9%), diarrhea (6.8%), pain in extremity (6.0%), and urinary tract infection (5.7%).

Table 4 summarizes the frequency of clinical adverse reactions, regardless of causality, reported in ≥ 2% and at a rate greater than placebo in patients treated with atorvastatin (n=8755), from seventeen placebo-controlled trials.

Postmarketing Experience

Because the reactions below are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The additional events described below have been identified during post-approval use of ezetimibe and/or atorvastatin.

Blood and lymphatic system disorders: thrombocytopenia

Nervous system disorders: headache; paresthesia; peripheral neuropathy

There have been rare postmarketing reports of cognitive impairment (e.g., memory loss, forgetfulness, amnesia, memory impairment, confusion) associated with statin use. These cognitive issues have been reported for all statins. The reports are generally nonserious, and reversible upon statin discontinuation, with variable times to symptom onset (1 day to years) and symptom resolution (median of 3 weeks).

Gastrointestinal disorders: pancreatitis

Skin and subcutaneous tissue disorders: angioedema; bullous rashes (including erythema multiforme, Stevens-Johnson syndrome, and toxic epidermal necrolysis); rash; urticaria myopathy/rhabdomyolysis [see WARNINGS AND PRECAUTIONS]

There have been rare reports of immune-mediated necrotizing myopathy associated with statin use [see WARNINGS AND PRECAUTIONS].

Injury, poisoning and procedural complications: tendon rupture

Immune system disorders: anaphylaxis; hypersensitivity reactions

Hepatobiliary disorders: hepatitis; cholelithiasis; cholecystitis; fatal and nonfatal hepatic failure

Psychiatric disorders: depression

Laboratory abnormalities: elevated creatine phosphokinase
