Where to Get Free Narcan in Denver

April 2026 6 min read Homeless Denver

Narcan (naloxone) reverses opioid overdoses and saves lives. In Denver you can get it for free — no ID, no appointment, no prescription, and no cost. Here's exactly where to go and what to do.

Witnessing an overdose right now?

Call 911 immediately

Give Narcan if available, then call 911. Colorado's Good Samaritan Law (C.R.S. 18-1-711) protects you from drug possession charges when you call for help during an overdose.

What is Narcan?

Narcan is a brand name for naloxone — a medication that rapidly reverses an opioid overdose from heroin, fentanyl, oxycodone, or other opioids. It works within minutes and is safe to give even if you're unsure whether opioids are involved. It will not hurt someone if they have not taken opioids.

The nasal spray version is the most common. You don't need medical training to use it. Signs of overdose include: not breathing, lips turning blue, pinpoint pupils, won't wake up, gurgling sounds.

How to use Narcan nasal spray

  1. Call 911 first — Tell them someone is unresponsive and may have overdosed.
  2. Lay the person on their back and tilt their head back slightly to open the airway.
  3. Peel back the foil and hold the Narcan device with your thumb on the bottom, two fingers on the nozzle.
  4. Insert the nozzle into one nostril and press the plunger firmly to release the full dose.
  5. Wait 2–3 minutes. If there is no response, give a second dose in the other nostril.
  6. Put the person in the recovery position (on their side) to prevent choking if they vomit.
  7. Stay with them until paramedics arrive. Naloxone wears off in 30–90 minutes — the person may need additional doses.
Important

Naloxone can cause withdrawal symptoms

When Narcan reverses an overdose, the person may wake up in withdrawal — confused, agitated, or in pain. This is normal. Stay calm, reassure them, and keep them from using more drugs before the naloxone wears off. The goal is keeping them alive until help arrives.

Colorado's Good Samaritan Law

Colorado law (C.R.S. 18-1-711) protects people who call 911 during an overdose from prosecution for drug possession. You will not be arrested simply for calling for help. This protection applies to the person who called and the person experiencing the overdose.

The law does not protect against other charges (warrants, distribution, etc.), but drug possession is specifically covered when you make the call in good faith.

Fentanyl test strips

Fentanyl is now found in many drugs, including those not typically associated with opioids. Free fentanyl test strips are available at Denver Public Health's harm reduction program and HRAC. They let you test a small amount of a substance before use to detect fentanyl.
