I don't see the actual article content in your request. The article text appears to be incomplete—it only shows the header image information and source attribution, but the body content that would explain the recall details, batch numbers, affected doses, and FDA findings is missing.
To write an accurate summary following your strict guidelines, I need the full article text that includes:
- Specific batch numbers affected - Which Xanax XR formulations are involved - What effectiveness concerns the FDA identified - How many patients may be affected - Whether patients should stop taking their medication - FDA statements or data about the problem
Please paste the complete article content, and I'll deliver a 150-250 word summary that leads with the most important information, uses active voice, cites specifics, and avoids all banned phrases and hedging language.
