Juxtapid Boxed Warnings
Risk of hepatotoxicity.
Elevations in transaminases and increases in hepatic fat may occur; measure ALT, AST, alkaline phosphatase, total bilirubin before initiating therapy, and then ALT, AST monthly or before any dose increase for 1st year; subsequently, at least every 3 months. Adjust dose if ALT or AST are ≥3xULN; discontinue if clinically significant liver injury, bilirubin ≥2xULN, or active liver disease occurs. Chronic bowel or pancreatic diseases that predispose to malabsorption. Adhere to low-fat diet to reduce risk of GI effects. Galactose intolerance, Lapp lactase deficiency, glucose-galactose malabsorption: avoid. Renal impairment. Embryo-fetal toxicity. Advise females of reproductive potential to use effective contraception during and for 2 weeks after the last dose. Nursing mothers: not recommended.
See Contraindications and Adults. Potentiated by CYP3A4 inhibitors (omit grapefruit juice). Potentiates warfarin; monitor INR. Risk of myopathy (including rhabdomyolysis) with simvastatin or lovastatin; reduce simvastatin dose by 50% (limit to 20mg daily [or 40mg daily for those previously tolerated simvastatin 80mg daily for ≥1 year without muscle toxicity]) or consider reducing lovastatin dose when initiating lomitapide. Consider dose reduction of P-gp substrates. Max one alcoholic drink/day. Caution with other hepatotoxic drugs (eg, isotretinoin, amiodarone, acetaminophen, methotrexate, tetracyclines, tamoxifen). Concomitant other LDL-lowering drugs: not recommended. Separate bile acid sequestrants by at least 4hrs.

Diarrhea (if severe, consider reducing dose or suspending use), nausea, dyspepsia, vomiting, abdominal pain; hepatotoxicity (including steatohepatitis, hepatic failure) possible, reduced absorption of fat soluble vitamins.
