⚠️ Opioid + Benzodiazepine Co-Prescriber

This provider prescribes both opioids and benzodiazepines. The FDA has issued a Black Box Warning about the life-threatening risks of concurrent use.

🔎 Data Overview

💰

Cost per patient is 560% above the specialty average. Extreme cost outliers may indicate prescribing of unnecessarily expensive brand-name drugs or inappropriate drug utilization.

⚠️

This provider co-prescribes opioids and benzodiazepines — a combination carrying an FDA Black Box Warning due to increased risk of respiratory depression and death. While sometimes clinically necessary, this combination requires careful justification.
