Most people are familiar with the opioid epidemic in Ohio. Headlines warn of the dangers of heroin mixed with fentanyl, but an even deadlier drug has made an appearance in the state in recent years: xylazine. 

Xylazine is not FDA-approved for human consumption, but according to recent Ohio news reports, the sedative, commonly used in veterinary medicine, is now being mixed with heroin and fentanyl, increasing the risk of fatal overdoses. What’s worse, Narcan cannot revive someone who’s overdosed on the mixture. 

What Is Xylazine or “Tranq”?

Sometimes referred to by its street name “Tranq,” xylazine is a potent veterinary tranquilizer, often used to treat horses or cattle. Xylazine has muscle relaxant properties and is a central nervous system depressant. The drug is injected into the veins, muscles, or under the skin, and it may be used alongside other anesthetics like ketamine or halothane.

Xylazine has historically been used as a recreational drug adulterant in Puerto Rico and was associated with a series of drug-related deaths at a criminal justice hospital in Aguadilla, Puerto Rico. Xylazine abuse was common in Puerto Rico in the early 2000s, and by 2006, the drug had made its way to the United States. The Philadelphia Medical Examiner’s Office detected xylazine in overdose deaths that also featured fentanyl. 

According to the Drug Enforcement Administration (DEA), xylazine typically comes in a liquid solution and helps with handling large animals and performing diagnostic or surgical procedures. It is also used as a pain reliever and local anesthetic in veterinary medicine. The drug has been studied for use in humans, but trials have been discontinued due to severe side effects in human populations. 

Xylazine Effects on Humans

Given that xylazine is designed to be a horse tranquilizer, its effects on humans can be fatal. Since it is a central nervous system depressant, xylazine in humans can cause respiratory depression, slowed heart rate and low blood pressure. 

According to the DEA, other side effects of xylazine in humans include:

• Blurry vision
• Disorientation
• Feelings of drowsiness
• High blood sugar
• Staggering
• Coma

Someone under the influence of xylazine may display some of the above symptoms and appear especially sleepy or sedated. While people may abuse xylazine because they enjoy its sedative properties, they are often unaware they are using it because it is mixed with opioids. When a person purchases these drugs off the street, they may be unknowingly ingesting xylazine as well.

Even unintentional xylazine use can lead to a dangerous addiction. Repeated use of this substance can make a person physically dependent upon xylazine, in addition to their dependence on the opioids it’s mixed with. Abusing two or more substances at once is called polysubstance abuse. Not only is polysubstance abuse more dangerous, but it can make treating the addiction even more difficult. 

Xylazine and Narcan

Unlike opioids such as heroin or fentanyl, an overdose from xylazine cannot be reversed with Narcan (naloxone), a life-saving medication that combats opioid overdoses. If xylazine causes respiratory depression or dangerously low blood pressure when combined with an opioid, naloxone may not reverse these side effects enough to prevent death, even if it does block the opioid’s effects.

Xylazine and Overdose Deaths in Ohio

Unfortunately, xylazine has come to the forefront in Ohio overdose statistics, as it has become more involved in overdose deaths in the Midwest. According to a Franklin County Ohio coroner report, the drug was responsible for 3.4% of the county’s overdose deaths in 2020, up from 2.1% in 2019. 

However, the horse tranquilizer may be involved in more overdose cases than experts realize. Fentanyl was involved in 86% of overdose deaths in 2020, and xylazine is often mixed with fentanyl. 

Xylazine has also caused an uproar in neighboring Pennsylvania. The drug was detected in 2% of unintentional overdose deaths in Philadelphia between 2010 to 2015, but that number rose to 31% in 2019. All xylazine overdoses also involved fentanyl. Nationwide, 1.8% of overdose deaths were positive for xylazine in 2019, suggesting that the drug’s presence may be regional.
