If you have a prescription for the anti-anxiety medication Xanax (alprazolam), check your bottle.

On March 17, the Food and Drug Administration (FDA) listed a voluntary recall of one lot of the drug that failed a quality check. The recall was initiated by Viatris, the pharmaceutical company that makes brand-name Xanax.

The recalled medication includes 3-milligram pills of brand-name Xanax XR in bottles of 60 tablets. These are the “extended release” version of the drug. If you take generic alprazolam, this recall doesn’t affect you.

According to the enforcement report, the recall is classified as Class II, which means that if you use the recalled medication, you may experience “temporary or medically reversible adverse health consequences,” and the “probability of serious adverse health consequences is remote.”

This is not the most severe level of recall, but the batch of pills that failed quality tests may not dissolve the way they’re supposed to, potentially affecting how the active ingredients are released in the body. If a medication doesn’t dissolve properly, it might affect how much of the active ingredient actually gets into your bloodstream.

Pills with the lot number 8177156 and an expiration date of 02/28/2027 are being recalled. They were distributed to patients between 08/27/2024 and 05/29/2025, per a notice issued by the California State Board of Pharmacy. This is a voluntary recall at the retailer level, which means patients don’t need to take any action. Viatris said retailers such as pharmacies have been provided with instructions on how to return the pills.

If you’re worried about whether your Xanax is in the recall, talk to your doctor or pharmacist. You should never stop taking a medication like Xanax suddenly. Benzodiazepines can cause serious withdrawal.
