Epidiolex Warnings/Precautions
Warnings/Precautions
Risk of hepatocellular injury. Obtain ALT/AST and total bilirubin prior to, at 1 month, 3 months, and 6 months after initiation, and periodically thereafter; also obtain levels within 1 month after dose adjustments or concomitant drugs known to impact the liver. Evaluate and consider more frequent monitoring if elevated liver enzymes at baseline. Interrupt or discontinue if hepatic dysfunction occurs; discontinue if ALT/AST elevations >3×ULN and bilirubin >2×ULN, or sustained ALT/AST elevations >5×ULN. Monitor for somnolence and sedation. Monitor for emergence or worsening of depression, suicidal thoughts/behavior or any unusual changes in mood/behavior. Discontinue if hypersensitivity reactions occur. Withdraw gradually. Avoid abrupt cessation. Moderate or severe hepatic impairment. Elderly. Pregnancy. Nursing mothers.

Epidiolex Interactions
Interactions
Antagonized by strong CYP3A4 or CYP2C19 inducers: consider increasing Epidiolex dose. May potentiate CYP1A2 (eg, theophylline, caffeine, tizanidine), UGT1A9 (eg, diflunisal, propofol, fenofibrate), UGT2B7 (eg, gemfibrozil, lamotrigine, morphine, lorazepam), CYP2C8 or CYP2C9 (eg, phenytoin) substrates: consider reducing dose of these. May affect CYP2B6 (eg, bupropion, efavirenz) substrates: consider adjusting dose of these. Potentiates sensitive CYP2C19 substrates (eg, diazepam, clobazam), P-gp/CYP3A4 substrates (eg, everolimus), or other orally administered P-gp substrates (eg, sirolimus, tacrolimus, digoxin): monitor and consider reducing dose of substrates. Monitor with stiripentol. Increased transaminase elevations with concomitant valproate and/or clobazam; monitor more frequently, consider discontinuation or dose adjustment of these drugs. May increase risk of somnolence and sedation with concomitant clobazam, CNS depressants, alcohol; monitor.
