Benzodiazepines, commonly referred to as “benzos,” are a class of prescription medications primarily used to treat anxiety, insomnia, and seizures. These drugs, including well-known names like Valium, Xanax, and Klonopin, work by slowing down activity in the brain, producing a calming and sedative effect. While effective for certain medical conditions, it’s crucial to understand what benzos are, how they function, and the significant risks associated with their use, especially when combined with other substances.
Delving Deeper: How Benzodiazepines Work in the Brain
Benzodiazepines are classified as central nervous system depressants. They exert their effects by enhancing the activity of a neurotransmitter called gamma-aminobutyric acid (GABA) in the brain. GABA is the body’s natural tranquilizer, responsible for reducing neuronal excitability. By boosting GABA’s effects, benzos can effectively calm nerves, relax muscles, and induce sleep. This mechanism is why they are prescribed for conditions characterized by overactivity in the brain, such as anxiety disorders, where they help to reduce excessive worry and tension, or insomnia, where they aid in initiating and maintaining sleep.
Commonly prescribed benzodiazepines include:
- Alprazolam (Xanax): Often used for panic disorder and anxiety.
- Diazepam (Valium): Used for anxiety, muscle spasms, and seizures.
- Clonazepam (Klonopin): Prescribed for seizures and panic disorder.
- Lorazepam (Ativan): Used for anxiety and agitation.
- Temazepam (Restoril): Primarily used for insomnia.
These medications are powerful and, while beneficial under medical supervision, carry risks that should not be overlooked.
Understanding the Risks Associated with Benzo Use
While benzodiazepines can be therapeutic, they are not without potential dangers, especially when misused or combined with other substances. One of the primary concerns is their interaction with opioids. Opioids, a class of drugs that includes pain relievers like morphine and fentanyl, also depress the central nervous system. Combining benzos and opioids significantly amplifies the risk of life-threatening respiratory depression. Both substances can slow down breathing, and when taken together, this effect is intensified, potentially leading to overdose and death.

The graph illustrates the number of overdose deaths involving any opioid and the number of overdose deaths involving both any opioid and benzodiazepines from 2000 to 2020. The alt text is: Line graph showing the increase in overdose deaths involving opioids, with a significant portion also involving benzodiazepines, from 2000 to 2020.
The graph above underscores the alarming trend of opioid-involved overdose deaths where benzodiazepines are also implicated. In 2021, almost 14% of opioid overdose fatalities also involved benzodiazepines, highlighting the severity of this polysubstance use.
Furthermore, benzodiazepines themselves carry risks even when not combined with opioids. These include:
- Sedation and Impaired Cognition: Benzos can cause drowsiness, dizziness, and confusion, increasing the risk of accidents and falls.
- Tolerance and Dependence: With regular use, the body can develop tolerance, requiring higher doses to achieve the same effect. This can lead to physical and psychological dependence.
- Withdrawal Symptoms: Abruptly stopping benzodiazepines after prolonged use can trigger withdrawal symptoms, ranging from anxiety and insomnia to seizures, which can be life-threatening.
It’s also concerning that benzodiazepines have been found in the illicit opioid supply. This means individuals may unknowingly be taking benzos when they believe they are only consuming opioids, further escalating the risk of accidental overdose.
The Critical Warning: Co-Prescription of Opioids and Benzodiazepines
The dangers of combining opioids and benzodiazepines are so significant that health organizations like the Centers for Disease Control and Prevention (CDC) have issued strong warnings. The CDC’s Clinical Practice Guideline for Prescribing Opioids for Pain emphasizes extreme caution when prescribing these medications concurrently. The guideline advises clinicians to carefully weigh the benefits against the risks when considering prescribing both opioids and benzodiazepines to the same patient.
Both prescription opioids and benzodiazepines now carry “boxed warnings” from the U.S. Food and Drug Administration (FDA). A boxed warning is the FDA’s most stringent warning, highlighting significant adverse reactions, including death. These warnings specifically address the heightened risks associated with using these drugs in combination.
If you are prescribed any medication, it is vital to inform your healthcare provider about all other substances you are using, including prescription drugs, over-the-counter medications, alcohol, and illicit drugs. Open communication with your healthcare team is crucial for managing and mitigating the risks associated with medication use and preventing potentially fatal drug interactions. Understanding “What Is A Benzo” and its potential dangers is a critical step in ensuring your safety and well-being.
