Side Effects of Juxtapid

Juxtapid can cause serious side effects, including:

  • liver problems. See “Drug Precautions”..
  • harm to your unborn baby. See “Drug Precautions".
  • gastrointestinal symptoms. Diarrhea, nausea/vomiting, and stomach pain/discomfort are very common with Juxtapid. Strictly following a low-fat diet may help lower the chance of having these symptoms.
  • problems absorbing certain nutrients. Juxtapid may decrease your ability to absorb fat-soluble nutrients such as Vitamin E and fatty acids. You should take supplements each day that contain fat-soluble vitamins. People with bowel or pancreas problems may have an increased chance of not being able to absorb these nutrients.
  • increased levels of certain blood thinners. Juxtapid can increase the level of the blood thinner, warfarin (Coumadin, Jantoven). If you take warfarin, your doctor should check your blood clotting times frequently, especially after your dose of Juxtapid changes.
  • liver problems caused by certain drugs. Certain medicines can cause liver problems, including isotretinoin, acetaminophen, methotrexate, tetracyclines, and tamoxifen. If you take these medicines with Juxtapid your doctor may do blood tests more often to check your liver.

The most common side effects of Juxtapid include:

Juxtapid FDA Warning

WARNING: RISK OF HEPATOTOXICITY
Juxtapid can cause elevations in transaminases. In the Juxtapid clinical trial, 10 (34%) of the 29 patients treated with Juxtapid had at least one elevation in alanine aminotransferase (ALT) or aspartate aminotransferase (AST) ≥3x upper limit of normal (ULN). There were no concomitant clinically meaningful elevations of total bilirubin, international normalized ratio (INR), or alkaline phosphatase.


Juxtapid also increases hepatic fat, with or without concomitant increases in transaminases. The median absolute increase in hepatic fat was 6% after both 26 and 78 weeks of treatment, from 1% at baseline, measured by magnetic resonance spectroscopy. Hepatic steatosis associated with Juxtapid treatment may be a risk factor for progressive liver disease, including steatohepatitis and cirrhosis.

Measure ALT, AST, alkaline phosphatase, and total bilirubin before initiating treatment and then ALT and AST regularly as recommended. During treatment, adjust the dose of Juxtapid if the ALT or AST are ≥3x ULN. Discontinue Juxtapid for clinically significant liver toxicity.

Because of the risk of hepatotoxicity, Juxtapid is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Juxtapid REMS Program.
