Opioid Overdose Basics
information below is from the CDC

Opioid overdose happens when too much of the drug overwhelms the brain and interrupts the body’s

natural drive to breathe.

Prescription opioids (like hydrocodone, oxycodone, and morphine) and illicit opioids (like heroin and illegally made fentanyl) are powerful drugs that  have a risk of a potentially fatal overdose.

Anyone who uses opioids can experience an overdose, but certain factors may increase risk including but not limited to:

  • Combining opioids with alcohol or certain other drugs

  • Taking high daily dosages of prescription opioids

  • Taking more opioids than prescribed

  • Taking illicit or illegal opioids, like heroin or illicitly-manufactured fentanyl, that could could possibly contain unknown or harmful substances

  • Certain medical conditions, such as sleep apnea, or reduced kidney or liver function

  • Age greater than 65 years old

Emerging Issues of Fentanyl and Xylazine

information below is from the CDC

Fentanyl: synthetic (manufactured) opioid that is up to 50 times stronger than heroin and 100 times stronger than morphine. It is a major contributor to fatal and nonfatal overdoses in the US.

Xylazine: also referred to as "tranq." It is a non-opioid veterinary tranquilizer not approved for humans. Xylazine is increasingly being found in the US illegal drug supply and linked to overdose deaths. Read more about xylazine here.

Signs and Symptoms of an Overdose
information below is from the CDC

During an overdose, breathing can be dangerously slowed or stopped, causing brain damage or death. It’s important to recognize the signs and act fast. Signs include:

  • Small, constricted “pinpoint pupils”

  • Falling asleep or loss of consciousness

  • Slow, shallow breathing

  • Choking or gurgling sounds

  • Limp body

  • Pale, blue, or cold skin

What To Do If You Think Someone is Overdosing

It may be hard to tell if a person is high or experiencing an overdose. If you aren’t sure, it’s best to treat it like an overdose— you could save a life.

  1. Call 911 immediately.

  2. Administer naloxone, if available.

  3. Try to keep the person awake and breathing.

  4. Lay the person on their side to prevent choking.

  5. Stay with him or her until emergency workers arrive.


Overdose Prevention and Harm Reduction:

There are a variety of ways to help reduce opioid misuse and prevent an overdose from occurring.  

A. PDMP -Prescription Drug Monitoring Program

Wisconsin uses a Prescription Drug Monitoring Program that helps healthcare professionals to effectively monitor and control the amount of prescriptions for controlled substance medications. 

Please visit the PDMP Website for Wisconsin to learn more.

B. Good Samaritan Law

This law protects all people who help an individual experiencing an overdose to get the care needed.

Read more about the Good Samaritan Law, 895.48(1)


C. Narcan (Naloxone)

Narcan is a medication that can reverse an overdose caused by an opioid. It is available as an injection or as a nasal spray. All pharmacists in Wisconsin have a standing order to provide Narcan to the public without a direct prescription.

This map also identifies locations where Narcan is available around Milwaukee County.

D. Fentanyl Test Strips

Fentanyl Test Strips (FTS) are small strips of paper than can detect the presence of fentanyl in all different kinds of drugs, including cocaine, methamphetamine, heroin, pills, powders and injectables. 

Fentanyl Test Strips can tell you if your drugs contain fentanyl, but not how much fentanyl there is or how strong it is.

To learn how to test your drugs using fentanyl test strips (which are available at our harm reduction vending machines!), please view this brochure.

E. Medication Drop Box

It is easy to let medication get into the wrong hands. 3 out of 5 teens say that it is easy to get medication from a medicine cabinet at home.


A map of all the Medication Drop Box locations links to Google and can help you find the nearest location to you.

The Health Department holds 2 drug take-back events every year, one in spring and one in fall. Stay tuned to see the dates of our drug take-back days in 2024.
