Can You Overdose on Trazodone? Signs and Risks

What Is Trazodone?

Trazodone is a prescription antidepressant sold under the brand name Desyrel. It belongs to the serotonin antagonist and reuptake inhibitor (SARI) class of medications, which work by increasing serotonin activity in the brain to improve mood, reduce anxiety, and support sleep. (MedlinePlus, NIH)

Doctors most commonly prescribe trazodone for major depressive disorder, but it is also used off-label for insomnia, generalized anxiety disorder, panic disorder, eating disorders, dementia-related agitation, and diabetic neuropathy.

For most people, trazodone is well tolerated. Common side effects include drowsiness, fatigue, dizziness, blurred vision, and mild weight changes. These typically ease as the body adjusts to the medication. More serious reactions, including rapid heartbeat, difficulty breathing, severe nausea, or signs of an allergic response, require prompt medical attention.

Can You Overdose on Trazodone?

Yes, a trazodone overdose is possible, though it is uncommon when the medication is taken as prescribed. The risk increases significantly when trazodone is combined with other substances, particularly central nervous system (CNS) depressants such as alcohol, benzodiazepines, or opioids. These combinations slow breathing and cardiovascular function to potentially life-threatening levels.

Taking trazodone in doses far above what is prescribed also raises overdose risk, as does using it alongside other serotonergic medications, which can trigger a dangerous buildup of serotonin in the body.

Trazodone Overdose Symptoms

Recognizing the signs of a trazodone overdose quickly can be life-saving. Symptoms may include:

• Irregular or rapid heartbeat
• Severely low blood pressure
• Chest pain or tightness
• Difficulty breathing
• Extreme drowsiness or unresponsiveness
• Severe dizziness or loss of coordination
• Seizures
• Coma

In rare cases, a trazodone overdose can trigger serotonin syndrome, a medical emergency in which serotonin accumulates to dangerous levels. Symptoms include high fever, muscle rigidity, rapid heart rate, diarrhea, vomiting, and seizures. Serotonin syndrome requires immediate emergency care. (MedlinePlus, NIH)

Cardiac and Blood Pressure Complications

Two specific complications are documented in trazodone overdose cases. First, the overdose can disrupt the heart’s electrical system, causing QT prolongation, a delay in the heart’s recharging cycle that can lead to dangerous arrhythmias. Second, a severe drop in blood pressure (hypotension) can occur, reducing blood flow to vital organs. Both complications require emergency medical management. (StatPearls, NCBI)

Fatal trazodone overdose is rare when trazodone is the only substance involved. Deaths associated with trazodone overdose most often involve polysubstance use, particularly with opioids, alcohol, or benzodiazepines. If you suspect someone is overdosing, call 911 immediately.

Trazodone Dosage and Overdose Threshold

For adults, trazodone is typically prescribed at 50 mg to 150 mg per day, with a recommended maximum of 400 mg daily for outpatient use. In some inpatient settings, physicians may prescribe higher doses under close monitoring. (MedlinePlus, NIH)

Overdose does not require exceeding the 400 mg threshold. Individual factors, including age, body weight, liver function, and concurrent substance use, all affect how trazodone is metabolized. A dose that is safe for one person may be dangerous for another. Combining trazodone with alcohol or other CNS depressants raises overdose risk at any dose level.

Safety Precautions When Taking Trazodone

Trazodone is a safe and effective medication for most people when used as directed. The following precautions reduce the risk of serious side effects and overdose:

• Take trazodone exactly as prescribed. Do not increase your dose or take it more frequently without your doctor’s guidance.
• Never combine trazodone with alcohol, opioids, benzodiazepines, or other CNS depressants without explicit medical approval.
• Tell your doctor about every medication, supplement, vitamin, or herbal remedy you take. Trazodone interacts with pain medications, migraine treatments, and other serotonergic drugs.
• Do not crush or chew trazodone tablets. Scored tablets may be split along the score line if a lower dose is needed.
• If trazodone causes digestive discomfort, take it with food.
• Avoid driving or operating machinery until you understand how trazodone affects your alertness and coordination.
• Do not stop taking trazodone abruptly. Speak with your doctor before reducing or discontinuing your dose.
• Keep trazodone stored safely away from children and pets, and never share your prescription.

Is Trazodone Addictive?

Trazodone is not considered addictive in the clinical sense. It does not produce euphoria or activate the brain’s reward pathways in the way that substances associated with addiction do. (StatPearls, NCBI)

However, long-term use can lead to physical dependence, meaning the body adapts to the presence of the medication. Stopping trazodone suddenly after extended use may cause withdrawal symptoms, including insomnia, irritability, and anxiety. This is a physiological response, not addiction, but it does mean that any changes to your trazodone regimen should be made gradually and under medical supervision.

Some people misuse trazodone for its sedative effects, using it to sleep or to blunt the effects of stimulants. This kind of misuse, particularly when combined with other substances, significantly raises the risk of overdose and other serious harms.

Treatment for Trazodone Misuse and Polysubstance Use

If trazodone is being misused, especially alongside other drugs or alcohol, the risk of overdose and long-term harm increases with continued use. Seeking help early gives you more options and a safer path forward.

Because trazodone can cause physical dependence, stopping it abruptly is not recommended. A medically supervised detox allows a clinical team to manage withdrawal safely, monitor your cardiovascular and neurological health, and reduce discomfort throughout the process.

Detox addresses the physical side of dependence, but recovery from substance misuse requires more. Comprehensive treatment works on the psychological patterns and underlying conditions, such as depression, anxiety, or trauma, that often drive substance use in the first place. Treatment approaches may include individual therapy, group counseling, cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and peer support.

At The Last Resort Recovery Center, we treat men dealing with substance use disorders, including those involving prescription drug misuse and polysubstance use. Our programs range from medical detox and residential care to partial hospitalization, intensive outpatient, and aftercare planning. If you or someone you care about is misusing trazodone or other substances, our team is available to answer questions and help you understand your options.
