A nationwide recall is underway for one lot of Xanax XR, the extended-release form of alprazolam used for panic disorder, after routine testing flagged problems with how the tablets dissolve. The lot number to watch is 8177156. The affected bottles contain sixty 3 mg extended-release tablets and carry an expiration date of Feb. 28, 2027. If you spot that lot number on your bottle, keep the medication in its original container and check with your pharmacist or prescribing clinician before making any changes to how you take it.
What Was Recalled
Viatris initiated a voluntary recall of Xanax XR Lot 8177156 on March 17 after testing showed the tablets did not meet required dissolution specifications. The Food and Drug Administration has listed the action as a Class II recall, which indicates temporary or reversible health effects are possible, according to the FDA Enforcement Report. The recall applies to 60-count bottles of the 3 mg extended-release tablets, sold under NDC 58151-506-91.
When And Where The Pills Were Distributed
The California State Board of Pharmacy posted a recall notice stating that the affected lot was distributed nationwide between Aug. 27, 2024, and May 29, 2025, and that “the risk to the patient associated with this event is considered to be negligible,” according to the California State Board of Pharmacy. It was not immediately clear how many bottles are included in the recall.
Why Failed Dissolution Matters
Extended-release tablets are designed to release medication slowly over time. A failed dissolution test means some pills may not release the active ingredient as intended, which can lead to inconsistent absorption and reduced effectiveness. Pharmacy trade reporting says pharmacists were advised to identify and quarantine Lot 8177156 and to coordinate with prescribers to provide unaffected supply, according to the Pharmacy Learning Network.
What To Do If You Have The Pills
Do not stop taking alprazolam or other benzodiazepines suddenly. MedlinePlus warns patients to talk with their doctor before changing or stopping the medication. If your bottle matches Lot 8177156, call your pharmacy or prescribing clinician to ask about returning or replacing the medication and whether your refill can be filled from a different lot.
Manufacturer Response And Next Steps
Viatris did not immediately respond to media requests for comment, according to NBC Chicago. Pharmacy trade reporting says Viatris notified consignees by letter rather than issuing a public press release, the Pharmacy Learning Network reported. Consumers with questions can consult the FDA or their state board of pharmacy for the latest recall instructions.
