Xanax - Prescription Information
Contraindications
Xanax tablets are contraindicated in patients with known sensitivity to this drug or other benzodiazepines. Xanax may be used in patients with open angle glaucoma who are receiving appropriate therapy, but is contraindicated in patients with acute narrow angle glaucoma.
Xanax is contraindicated with ketoconazole and itraconazole, since these medications significantly impair the oxidative metabolism mediated by cytochrome P450 3A (CYP3A) (see Warnings and Precautions-Drug Interactions).
