Everything you need to know about Alprazolam XR in 2026: what it is, FDA-approved uses, dosage guidelines, how to take it, and important safety information.
Alprazolam XR is the extended-release formulation of Alprazolam, a medication in the benzodiazepine class. You may also know it by its brand name, Xanax XR. Unlike the immediate-release version (Xanax), which is taken multiple times per day, Alprazolam XR is designed to release medication slowly throughout the day, allowing for once-daily dosing.
