Naloxone (Narcan)
Street names: Narcan, Kloxxado, Nyxoid, The opioid antidote
Overdose? Act now. Call emergency services — say "unresponsive, not breathing". Give naloxone for opioid-like signs. Hotlines
⚡What it does
- Retira los opiáceos de los receptores en 2–3 minutos – revuelve la respiración por sobredosis en minutos
- No tiene efecto sobre las drogas no opioides; no es alto; seguro dar incluso si no es seguro
⚠Key risks
- La vida media corta (30–90 minutos) en comparación con las horas de fentanilo – la persona puede re-overdose a medida que se desgasta.
- Precipita la retirada en los usuarios dependientes - espera rabia, vómitos, dolor (están vivos - ese es el punto)
- Los opioides de mayor potencia (nitazenos, carfentanil) pueden necesitar de 4 a 10 dosis.
- No reverte la xilazina (pero todavía la da por la mitad del fentanilo)
✚Overdose signs
- (Síntomas de sobredosis que trata): sin respuesta, pupilas punteadas, respiración lenta / garganta, labios azules
