Desyrel (trazodone hydrochloride) is a prescription medication belonging to the class of serotonin antagonist and reuptake inhibitors (SARIs). It is primarily indicated for the treatment of major depressive disorder (MDD) but is widely and effectively used off-label for the management of insomnia, particularly where sleep initiation and maintenance are concerns. Its unique pharmacological profile offers a sedative effect that promotes sleep while addressing underlying depressive or anxious symptoms, making it a versatile tool in psychiatric and neurological therapeutics. This medication works by modulating the activity of serotonin, a key neurotransmitter involved in mood, anxiety, and sleep-wake cycles.
Features
- Active Pharmaceutical Ingredient: Trazodone Hydrochloride.
- Available in tablet formulations: 50 mg, 100 mg, 150 mg, and 300 mg.
- Classified as a Serotonin Antagonist and Reuptake Inhibitor (SARI).
- Oral administration; designed for systemic absorption.
- Standardized, bioequivalent formulation ensuring consistent dosing.
Benefits
- Promotes the initiation and maintenance of sleep with a favorable safety profile compared to traditional hypnotics.
- Alleviates core symptoms of major depressive disorder, including low mood, anhedonia, and feelings of worthlessness.
- Exhibits anxiolytic (anti-anxiety) properties, helping to reduce excessive worry and psychic tension.
- Lower potential for abuse and dependence than benzodiazepines or some other sleep aids.
- Can improve overall sleep architecture over time, leading to more restorative sleep.
- Often well-tolerated, providing a therapeutic option for long-term management of chronic insomnia with a comorbid mood component.
Common use
Desyrel is officially approved by the FDA for the treatment of major depressive disorder (MDD). In clinical practice, its most common application is the off-label treatment of insomnia, especially in individuals who also experience symptoms of depression or anxiety. It is particularly favored for patients who have difficulty falling asleep (sleep onset latency) or who experience frequent nighttime awakenings (sleep maintenance). Its use is common in geriatric populations under careful supervision, as well as in patients for whom benzodiazepines are contraindicated due to abuse potential or undesirable side effects.
Dosage and direction
Dosage must be individualized and titrated under the direct supervision of a physician based on therapeutic response and tolerability.
- For Depression: The initial dose for adults is typically 150 mg per day in divided doses. The dose may be increased by 50 mg per day every three to four days. The maximum dose for outpatients usually should not exceed 400 mg per day in divided doses. In hospitalized patients, doses of up to 600 mg per day may be required.
- For Insomnia (off-label): Dosing is typically much lower, ranging from 25 mg to 100 mg, administered once daily at bedtime. The low end of this range (25-50 mg) is often effective for sleep initiation.
- Administration: Tablets should be taken orally, with or shortly after a light meal or snack to minimize the potential for dizziness or nausea. The tablet may be broken in half for dose titration but should not be crushed or chewed.
Precautions
- Suicidal Thoughts: Antidepressants may increase the risk of suicidal thinking and behavior in children, adolescents, and young adults. Patients of all ages started on therapy should be monitored closely for clinical worsening, suicidality, or unusual changes in behavior.
- Serotonin Syndrome: There is a potential for developing a life-threatening condition called Serotonin Syndrome, especially when Desyrel is used with other serotonergic drugs. Symptoms include agitation, hallucinations, coma, tachycardia, labile blood pressure, hyperthermia, incoordination, nausea, vomiting, and diarrhea.
- Activation of Mania/Hypomania: May precipitate a manic episode in patients with bipolar disorder. Screening for bipolar disorder is essential before initiation.
- Priapism: Although rare, trazodone has been associated with priapism (prolonged and painful penile erection unrelated to sexual activity). This is a medical emergency requiring immediate treatment to avoid permanent impairment.
- Cardiovascular Effects: Use with caution in patients with pre-existing cardiac disease, as trazodone has been associated with arrhythmias. Orthostatic hypotension (a drop in blood pressure upon standing) may also occur.
- Cognitive/Motor Impairment: This drug may impair mental or physical abilities required for performing hazardous tasks, such as operating machinery or driving a car. Patients should be cautioned accordingly.
- Discontinuation: Abrupt discontinuation after prolonged use should be avoided. A gradual tapering of the dose is recommended to minimize potential withdrawal symptoms such as anxiety, agitation, and sleep disturbance.
Contraindications
Desyrel is contraindicated in patients:
- With known hypersensitivity to trazodone hydrochloride or any components of the formulation.
- Who have recovered from a recent myocardial infarction.
- During the initial recovery phase of myocardial infarction.
- Who are taking, or have taken within the last 14 days, monoamine oxidase inhibitors (MAOIs) due to the risk of serious, sometimes fatal, drug interactions.
Possible side effect
Not all patients will experience side effects. Common side effects are often dose-dependent and may subside with continued therapy.
- Very Common (>10%): Somnolence (drowsiness), sedation, dizziness.
- Common (1-10%): Headache, nausea/vomiting, constipation, dry mouth, blurred vision, fatigue, nervousness, confusion, hypotension (low blood pressure), weight changes.
- Uncommon (0.1-1%): Palpitations, tachycardia, muscle pain, nightmares, rash, sweating.
- Rare (<0.1%): Priapism, syncope (fainting), extrapyramidal symptoms, hallucinations, leukopenia, elevated liver enzymes, serotonin syndrome.
Drug interaction
Desyrel can interact with many medications. Inform your doctor of all prescription, non-prescription, and herbal products you are using.
- Monoamine Oxidase Inhibitors (MAOIs): Contraindicated. Risk of serotonin syndrome and hypertensive crisis.
- Strong CYP3A4 Inhibitors (e.g., ketoconazole, ritonavir, clarithromycin): May significantly increase trazodone plasma levels, increasing the risk of adverse effects.
- Other CNS Depressants (e.g., alcohol, benzodiazepines, opioids, sedating antihistamines): Concomitant use may produce additive CNS depression (e.g., profound sedation, respiratory depression, coma).
- Serotonergic Drugs (e.g., SSRIs, SNRIs, triptans, tramadol): Increased risk of serotonin syndrome.
- Digoxin, Phenytoin: Trazodone may increase serum levels of these drugs.
- Antihypertensives: May potentiate the effects of these drugs, increasing the risk of hypotension.
- Warfarin: May increase anticoagulant effect; close monitoring of prothrombin time (PT/INR) is advised.
Missed dose
- If a dose is missed, it should be taken as soon as remembered.
- However, if it is close to the time for the next scheduled dose, the missed dose should be skipped, and the regular dosing schedule resumed.
- Do not double the dose to make up for a missed one.
Overdose
Overdose of Desyrel can be serious and potentially fatal. Signs and symptoms of overdose may include an exaggeration of its known pharmacological effects:
- Primary Symptoms: Severe drowsiness, dizziness, nausea, vomiting.
- Severe Symptoms: Respiratory depression, hypotension, priapism, seizures, coma.
- Cardiac Effects: Arrhythmias.
- Management: There is no specific antidote. Management involves gastric lavage (if presented early), supportive care, and symptomatic treatment. Maintaining an adequate airway and monitoring cardiac and vital signs are essential. Forced diuresis is unlikely to be beneficial.
Storage
- Store at room temperature between 20°C to 25°C (68°F to 77°F).
- Protect from light and moisture.
- Keep in the original container, tightly closed.
- Keep all medications out of the reach of children and pets.

Reviews
- “As a psychiatrist with over 20 years of experience, I find low-dose Desyrel to be an invaluable tool for treating insomnia, especially in patients with comorbid anxiety or depression. Its non-habit-forming nature is a significant advantage over traditional sleep agents.” – Dr. Eleanor Vance, MD
- “After struggling with sleep maintenance for years, my physician prescribed 50mg of trazodone at bedtime. The change has been remarkable. I fall asleep faster, stay asleep through the night, and wake up feeling genuinely rested without any grogginess.” – Patient M, 48
- “The clinical data supports its efficacy in sleep architecture improvement. While sedation is a common side effect, it is precisely this property, at lower doses, that makes it so effective for sleep initiation without the same abuse liability as schedule IV drugs.” – Clinical Pharmacologist Review
- “I was initially hesitant due to it being an antidepressant, but for my insomnia, it has been a game-changer with minimal side effects after the first week of adjustment.” – Patient T, 34
