Idelalisib and Xanax

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Idelalisib may increase the blood levels and effects of ALPRAZolam. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

GENERALLY AVOID: Coadministration with idelalisib may increase the plasma concentrations of drugs that are substrates of CYP450 3A4. Idelalisib has been shown to be a potent inhibitor of this isoenzyme. In healthy volunteers, administration of a single 5 mg dose of midazolam, a CYP450 3A4 probe substrate, with idelalisib 150 mg for 15 doses increased mean midazolam peak plasma concentration (Cmax) by 2.4-fold and systemic exposure (AUC) by 5.4-fold.

MANAGEMENT: Use of idelalisib should generally be avoided with drugs that are primarily metabolized by CYP450 3A4, particularly those with a narrow therapeutic range (e.g., antiarrhythmics, anticonvulsants, antineoplastics, immunosuppressants) or those that are considered sensitive substrates (e.g., ergot derivatives, statins, oral midazolam, triazolam). Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever idelalisib is added to or withdrawn from therapy, if coadministration is required.
