Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines
⚡What it does
- Heavy sedation, slow breathing
- Blackouts lasting hours
- Severe skin wounds (eschar) at injection sites
⚠Key risks
- Not an opioid — naloxone does NOT reverse it; it still kills breathing
- Flesh-rotting wounds (tranq lesions) that lead to amputation
- Withdrawal on top of opioid withdrawal, hard to treat
✚Overdose signs
- Unresponsive with slow breathing
- Blue-gray skin
- Severe hypotension (very low blood pressure)
