Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines
⚡What it does
- Centrally-acting muscle relaxant — sedation and relief of muscle spasm, not a true 'relaxant' at the muscle itself
- Milder and less abusable than carisoprodol (Soma)
- Commonly combined with ibuprofen or acetaminophen in brand products
⚠Key risks
- Compounds every CNS depressant: alcohol, opioids, benzos and sleep meds together can slow breathing to dangerous levels
- Crushing and injecting tablets causes abscesses, collapsed veins and infection — a documented jail/practice
- Can cause extreme sedation and confusion in older adults (falls, delirium)
✚Overdose signs
- Extreme drowsiness, slow breathing, seizures (rare), low blood pressure
- Bluish lips, unresponsiveness — call emergency services
