Desyrel (trazodone hydrochloride) is a prescription medication classified as a serotonin antagonist and reuptake inhibitor (SARI). It is primarily indicated for the treatment of major depressive disorder (MDD) in adults. Its unique pharmacological profile allows it to modulate serotonin levels in the brain, which plays a crucial role in mood regulation, anxiety, and sleep architecture. Unlike many traditional antidepressants, Desyrel is notable for its sedative properties, making it a valuable option for patients experiencing depression with concomitant insomnia. This comprehensive product card provides an in-depth, expert-level overview of Desyrel, detailing its features, benefits, appropriate usage, and essential safety information for healthcare professionals and informed patients.

- Exhibits antagonism at 5-HT2A/2C receptors and inhibits serotonin reuptake
- Non-tricyclic chemical structure, reducing anticholinergic side effects
- FDA-approved for the treatment of major depressive disorder
- Off-label uses include insomnia, anxiety disorders, and augmentation in treatment-resistant depression
Benefits
- Effectively alleviates symptoms of major depressive disorder, including low mood, anhedonia, and fatigue
- Promotes improved sleep onset and maintenance due to its sedative effects, beneficial for patients with depression-related insomnia
- Lower incidence of sexual dysfunction compared to SSRIs and SNRIs, enhancing treatment adherence
- Minimal anticholinergic side effects, reducing risks such as dry mouth, constipation, and blurred vision

- Flexible dosing allows for tailored treatment regimens to meet individual patient needs and tolerability
Common use
Desyrel is primarily prescribed for the management of major depressive disorder in adults. Its efficacy in improving mood, energy levels, and interest in daily activities has been well-established in clinical studies. Additionally, due to its pronounced sedative effects, it is frequently used off-label for the treatment of insomnia, particularly in cases where sleep disturbances are linked to depressive or anxiety disorders. In some clinical scenarios, Desyrel may be employed as an augmenting agent alongside other antidepressants to enhance therapeutic response in treatment-resistant depression. It is also sometimes utilized in low doses for managing anxiety symptoms, though this is not an FDA-approved indication.
Dosage and direction
The dosage of Desyrel must be individualized based on the patient’s condition, response to therapy, and tolerance. For the treatment of depression in adults, the initial dose is typically 150 mg per day, administered in divided doses after meals or snacks to minimize gastrointestinal upset. The dose may be increased by 50 mg per day every three to four days, as tolerated. The maximum recommended dose for outpatients is 400 mg per day, while inpatients may receive up to 600 mg per day in divided doses. For off-label use in insomnia, lower doses (25–100 mg) are commonly prescribed, administered at bedtime. It is crucial to follow the prescribing healthcare provider’s instructions precisely and not to adjust the dose without consultation. Tablets should be swallowed whole and not crushed or chewed.
Precautions
Patients taking Desyrel should be monitored for the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, and mania, particularly during the initial few months of therapy or after dose adjustments. Due to its sedative properties, Desyrel may impair mental or physical abilities required for performing hazardous tasks, such as operating machinery or driving. Caution is advised in patients with a history of cardiovascular disease, as trazodone has been associated with orthostatic hypotension and, rarely, arrhythmias. Regular assessment of renal and hepatic function is recommended in patients with pre-existing conditions. Desyrel should be used with caution in elderly patients, who may be more sensitive to its effects, particularly sedation and hypotension.
Contraindications
Desyrel is contraindicated in patients with known hypersensitivity to trazodone hydrochloride or any component of the formulation. Concomitant use with monoamine oxidase inhibitors (MAOIs) is contraindicated due to the risk of serotonin syndrome; at least 14 days should elapse between discontinuation of an MAOI and initiation of Desyrel. It is also contraindicated in patients during the acute recovery phase following myocardial infarction. Use is not recommended in patients with severe cardiac disease or a history of priapism.
Possible side effect
Common side effects of Desyrel include drowsiness, dizziness, fatigue, headache, dry mouth, blurred vision, constipation, and nausea. Less frequently, patients may experience orthostatic hypotension, syncope, palpitations, weight changes, and nightmares. Although rare, serious side effects can occur, such as priapism (prolonged and painful erection), which requires immediate medical attention to avoid permanent damage. Serotonin syndrome, characterized by agitation, hallucinations, tachycardia, hyperthermia, and muscle rigidity, is a potential risk, particularly when used with other serotonergic drugs. Any unusual or severe side effects should be reported to a healthcare provider promptly.
Drug interaction
Desyrel has the potential for significant drug interactions. Concomitant use with MAOIs, other SSRIs, SNRIs, triptans, tramadol, or other serotonergic agents increases the risk of serotonin syndrome. It may enhance the sedative effects of alcohol, benzodiazepines, opioids, and other CNS depressants. Trazodone is metabolized by CYP3A4; inhibitors of this enzyme (e.g., ketoconazole, ritonavir) can increase trazodone levels, while inducers (e.g., carbamazepine, rifampin) may decrease its efficacy. Caution is advised when using with antihypertensives due to additive hypotensive effects, and with drugs that prolong the QT interval. Healthcare providers should review all medications, including over-the-counter products and herbal supplements, before initiating Desyrel.
Missed dose
If a dose of Desyrel is missed, it should be taken as soon as remembered, unless it is almost time for the next scheduled dose. In that case, the missed dose should be skipped, and the regular dosing schedule resumed. Doubling the dose to make up for a missed one is not recommended, as it may increase the risk of side effects. Patients should consult their healthcare provider if they are uncertain about how to manage missed doses.
Overdose
Overdose of Desyrel can be serious and potentially fatal. Symptoms may include severe drowsiness, vomiting, priapism, respiratory depression, hypotension, seizures, and coma. Serotonin syndrome may occur in cases of significant overdose, particularly with concomitant use of other serotonergic agents. In the event of suspected overdose, immediate medical attention is essential. Treatment is supportive and symptomatic; there is no specific antidote. Activated charcoal may be administered if ingestion was recent. Priapism requires urgent urological intervention to prevent irreversible damage.
Storage
Desyrel tablets should be stored at room temperature, between 20°C to 25°C (68°F to 77°F), in a tightly closed container, and protected from light and moisture. Keep out of reach of children and pets. Do not use beyond the expiration date printed on the packaging. Unused medication should be disposed of properly according to local guidelines or through a medication take-back program to prevent accidental ingestion or environmental contamination.

Reviews
Clinical studies and patient reports generally indicate that Desyrel is effective in alleviating depressive symptoms and improving sleep quality, particularly in individuals with comorbid insomnia. Many patients appreciate the reduced incidence of sexual side effects compared to other antidepressants. However, some users report significant drowsiness and dizziness, especially during the initial weeks of therapy. Healthcare providers often note its utility in low doses for insomnia management, though emphasize the importance of monitoring for side effects such as orthostatic hypotension and priapism. Overall, Desyrel is regarded as a valuable therapeutic option within its indicated and off-label uses when prescribed and monitored appropriately.
