Ocaliva (obeticholic acid) and Alcohol / Food Interactions

There is 1 alcohol/food/lifestyle interaction with Ocaliva (obeticholic acid):


Caffeine ↔ obeticholic acid

Moderate Drug Interaction

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with obeticholic acid may increase the plasma concentrations of drugs that are substrates of the CYP450 1A2 isoenzyme. The mechanism is decreased clearance due to inhibition of CYP450 1A2 activity by obeticholic acid and its glycine and taurine conjugates. When a single 200 mg dose of caffeine (a probe CYP450 1A2 substrate) was administered with obeticholic acid 10 mg once daily, caffeine peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 6% and 42%, respectively.

MANAGEMENT: Caution is advised when obeticholic acid is prescribed with drugs that undergo metabolism by CYP450 1A2, particularly those with a narrow therapeutic range such as theophylline or tizanidine. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever obeticholic acid is added to or withdrawn from therapy.
