ER Clinicians Need a Kratom Playbook: New Narrative Review Covers Presentation, Diagnosis, and Treatment

Why it matters

As kratom-related emergency visits increase nationwide, emergency physicians often lack standardized guidance for recognizing and managing kratom toxicity — this review provides a practical clinical framework to fill that gap.

The big picture

Kratom's expanding use has outpaced clinical awareness. Unlike opioids or benzodiazepines, kratom is not detected by standard urine drug screens, and many ER providers have limited familiarity with its toxidrome. Poison control calls and hospital encounters involving kratom have risen sharply over the past decade. This narrative review synthesizes the existing literature specifically for emergency medicine practitioners, offering a clinical roadmap from triage to treatment.

Key findings

• Kratom toxicity in the ER typically presents as nausea, vomiting, tachycardia, agitation, and sometimes respiratory depression — overlapping with opioid and stimulant toxidromes
• Standard urine drug screens do not detect kratom alkaloids; specific liquid chromatography-mass spectrometry testing is required but rarely available in real time
• Naloxone has shown variable effectiveness in reversing kratom-related sedation and respiratory depression — response depends heavily on the specific alkaloids consumed and dose
• Co-ingestion with other substances (alcohol, benzodiazepines, prescription opioids) is present in a majority of serious kratom ED cases and significantly worsens outcomes
• Treatment is largely supportive: airway management, hydration, and monitoring; no kratom-specific antidote exists

What they say

The authors concluded: "Emergency physicians need to maintain a high index of suspicion for kratom toxicity in patients presenting with mixed opioid-stimulant symptoms, particularly when routine drug screening is negative and the patient has used herbal or botanical products."

Bottom line

Standard drug screens miss kratom entirely — emergency physicians must rely on clinical judgment and history to diagnose and treat kratom toxicity, for which no specific antidote yet exists.
