Trazodone And Alcohol: What Happens When You Mix Them

What Happens When You Mix Alcohol With Trazodone?

Trazodone is a prescription medication often used off-label (non-FDA-approved) for insomnia, along with its FDA-approved use for major depressive disorder.[1] Understanding how trazodone affects the body independently makes it simpler to understand how the effects of alcohol could amplify the side effects of trazodone.

Trazodone is classified within a drug category known as a serotonin antagonist and reuptake inhibitor (SARI) and is sold under several different names, including Desyrel.[2] The most concerning aspect of consuming alcohol while taking trazodone is the possibility of additive CNS depression. Alcohol is also a CNS depressant, so consuming alcohol while taking trazodone may exacerbate sedation, decrease reaction times, and worsen cognitive function, such as confusion or difficulty concentrating.

Consumption of alcohol while taking trazodone may substantially increase drowsiness and impairments, increase the likelihood of falling or becoming injured due to diminished cognitive function caused by minimal amounts of alcohol, and diminish the efficacy of trazodone over extended periods.[3] Due to the fact that trazodone is commonly administered for sleep disorders, consuming trazodone and alcohol prior to bedtime poses substantial risks in inducing extreme drowsiness that persists into the subsequent day.

Interaction Between Trazodone and Alcohol Within the Body

Trazodone affects neurotransmitter systems, specifically serotonergic activity, and possesses minor histaminic activity, which also contributes to its sedative properties.[4] Alcohol impacts GABA and glutamate pathways within the brain, thereby enhancing inhibitory neural transmission.[5] The combined effect of both substances interacting simultaneously within the body typically exceeds the effects each produces individually.

As opposed to being linearly related, the degree of interaction varies widely among individuals and cannot be accurately predicted. For example, even a small amount of alcohol consumption can elicit a disproportionately large reaction dependent on the dose of trazodone administered, the length of time since the last dose of trazodone was administered, individual tolerance to CNS depressants, and metabolic variability across individuals.

Individuals concurrently administering other CNS depressants (such as other benzodiazepines like Alprazolam or Valium) experience an elevated risk of impaired cognitive function, respiratory depression (shallow breathing resulting in CO2 accumulation in tissues and a deficiency in O2), and, in extremely rare instances, serotonin syndrome, a potentially lethal complication linked to excessive serotonergic activity in the brain.[6]

Effects of Mixing Trazodone With Alcohol

Immediate short-term effects:

Individuals who consume alcohol while taking trazodone typically exhibit:[7]

• Extreme drowsiness
• Decreased equilibrium
• Speech slurring
• Impaired thought processes and ability to make decisions
• Nausea, lightheadedness, or blurred vision

Greater risk of severe reactions:

In some instances, the combination can induce:

• Decreased blood pressure
• Blackouts
• Memory dysfunction
• Increased susceptibility to injuries due to falls
• Exacerbated depression symptomology on the day immediately following ingestion.

Impact on Sleep

Alcohol can alter normal sleep patterns, produce next-day grouchiness, and increase the severity of rebound insomnia, thereby thwarting the reasons many people take trazodone to begin with.

Trazodone vs. Wine and Other Types of Alcoholic Beverages

Wine is often considered less potent or gentler; however, there is no clinically relevant difference regarding interaction risk between beverage types. The main area of concern is ethanol concentration, not whether your alcoholic beverage comes from wine, beer, or spirits.

A single or two glasses of wine can produce enhanced sedation, greater impairment when consumed close to a dose of trazodone, and worsen next-day cognitive fogginess. Framing this risk in terms of “wine vs. liquor” can mislead individuals into believing that they are drinking “just enough” alcohol to avoid having a negative impact on them.

Is Moderate Drinking Safe With Trazodone?

Moderate drinking remains unsafe when combined with trazodone due to overlapping CNS effects. Infrequent drinking can produce unpredictable sedation, elevate the risk of unintentional injury, and destabilize mental health for individuals managing depression, anxiety, or another mood disorder. Most clinical guidelines recommend abstaining from alcohol altogether while taking trazodone due to individualized response variability.

Timing Between Consuming Alcohol and Trazodone

There is no universally accepted safe period between alcohol consumption and ingesting trazodone. Both drugs have varying half-lives, and metabolisms differ between individuals.

Taking trazodone after consuming alcohol earlier in the day can still cause an interaction based on that day’s ethanol consumption, individualized metabolism, and the time elapsed since the last dose.[8] Furthermore, alcohol can continue to affect the central nervous system (CNS) function into the next day, particularly after heavy consumption. This increases additive sedation even without mixing trazodone and a drink on the same day.

Factors That Increase the Danger of Interaction

Several factors can increase the danger of a hazardous interaction, including:[9]

• Taking high doses of trazodone, especially for purposes related to sleep
• Administering multiple sedatives (including benzodiazepines or opioids)
• Age, particularly older adults and slower metabolizers
• Liver disease
• History of substance abuse or addiction
• Co-existing mental health disorders such as depression or anxiety

Signs and Symptoms of Hazardous Interactions

Emergency medical treatment is needed immediately if any of the following occur after combining trazodone and alcohol:[10]

• Disorientation or inability to remain awake
• Irregular or shallow breathing
• Blackout
• Painful chest or marked dizziness
• Loss of coordination leading to falls
• Extreme sedation that is difficult to rouse from

Clinical Support and Structured Treatment for Co-Existing Substance Use Disorders

For those individuals who have found themselves regularly drinking alcohol while prescribed trazodone, structured care options exist. Treatment programs, both at inpatient and outpatient levels, can offer medical oversight of concurrent substance use disorders and medication interactions, support during detoxification for withdrawal symptoms and cravings, and coordinated treatment for co-existing substance use disorder and mental health conditions.

Research sponsored by NIAAA states that simultaneous administration of alcohol with CNS depressant medications elevates the risk of acute overdose and other adverse effects, and is one reason why treatment centers emphasize medically supervised care for early stages of recovery.[11] Evidence-based (practical application of findings from research currently available) support for rebuilding stability without relying on alcohol is provided through programs such as Agape’s PHP and IOP services in Fort Lauderdale, which provide integrated medical monitoring and therapy aimed at developing coping mechanisms that do not rely on alcohol.

Individuals contemplating entering an alcohol rehabilitation program while continuing treatment for their mental health disorder may find that addressing both concerns simultaneously provides a better foundation for achieving long-term wellness than addressing either separately.

Harm reduction considerations

Although completely eliminating alcohol use while taking trazodone presents the least risk possible, there are several harm-reduction-related recommendations worth noting:

• Never combine trazodone and alcohol on the same evening.
• Do not attempt to counteract trazodone-induced sedation with alcohol.
• Exercise caution regarding delayed, next-day impairment.
• Do not operate motor vehicles or equipment capable of causing damage if either substance was recently consumed.
• Discuss your use of alcohol with your prescribing clinician or other healthcare providers involved in your care.
