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) in adults, offering a dual mechanism of action that modulates serotonin levels in the central nervous system. Clinically, it is also widely utilized off-label for the management of insomnia due to its sedative properties, providing a non-habit forming alternative to traditional hypnotics. Its efficacy in improving sleep architecture, coupled with its antidepressant effects, makes it a versatile agent in neuropsychiatric care. This medication requires a thorough clinical assessment and prescription from a qualified healthcare provider to ensure appropriate and safe use.

Common use

Desyrel is most commonly prescribed for the treatment of major depressive disorder in adults. Its use is grounded in its ability to enhance serotonin activity, which plays a critical role in mood regulation. Beyond its approved indication, it is frequently used off-label for insomnia, particularly in cases where sleep disturbance is linked to depression or anxiety. Clinicians may also consider it for generalized anxiety disorder, although this use is less evidence-based. It is not typically used in pediatric or geriatric populations without careful risk-benefit assessment and dose adjustment.

Dosage and direction

The initial dosage for depression in adults is 150 mg per day in divided doses, which may be increased by 50 mg per day every three to four days. The maximum dose should not exceed 400 mg per day in outpatient settings or 600 mg per day in hospitalized patients. For insomnia, lower doses (25–100 mg) are typically used, administered 30 minutes before bedtime. Tablets should be swallowed whole with water and may be taken with or without food, though taking with food may reduce dizziness. Dosage must be individualized under medical supervision; never self-adjust.

Precautions

Patients should be monitored for clinical worsening, suicidality, or unusual changes in behavior, especially during the initial few months of therapy or after dose changes. Use with caution in patients with a history of cardiovascular disease, as trazodone has been associated with orthostatic hypotension and arrhythmias. Priapism, a prolonged and painful erection, is a rare but serious adverse effect requiring immediate medical attention. Sedation may impair alertness; avoid driving or operating machinery until response is known. Alcohol and CNS depressants should be avoided due to additive effects.

Contraindications

Desyrel is contraindicated in patients with known hypersensitivity to trazodone or any component of the formulation. It must not be used concomitantly with, or within 14 days of discontinuing, monoamine oxidase inhibitors (MAOIs) due to risk of serotonin syndrome. Use is also contraindicated during the acute recovery phase after myocardial infarction. Not recommended in patients with severe hepatic or renal impairment without close monitoring.

Possible side effect

Common side effects include drowsiness, dizziness, dry mouth, blurred vision, headache, and nausea. Less frequently, patients may experience constipation, fatigue, weight changes, or nightmares. Serious side effects, though rare, include priapism, serotonin syndrome, suicidal thoughts, orthostatic hypotension, arrhythmias, and manic episodes in susceptible individuals. Any unusual or severe symptoms should be reported to a healthcare provider immediately.

Drug interaction

Desyrel interacts with several medication classes. Concomitant use with MAOIs, other serotonergic drugs (e.g., SSRIs, SNRIs, triptans), may increase risk of serotonin syndrome. It may potentiate effects of CNS depressants like alcohol, benzodiazepines, and opioids. Use with antihypertensives may increase hypotension risk. Trazodone is metabolized by CYP3A4; inhibitors (e.g., ketoconazole) may increase levels, while inducers (e.g., carbamazepine) may decrease efficacy. Digoxin and phenytoin levels may be affected. Always inform your prescriber of all medications, including OTC and herbal products.

Missed dose

If a dose is missed, take it as soon as remembered unless it is almost time for the next dose. Do not double the dose to catch up. If regularly missing doses, discuss with a healthcare provider to improve adherence or adjust regimen.

Overdose

Overdose may manifest as excessive sedation, vomiting, respiratory depression, hypotension, priapism, or seizures. In case of suspected overdose, seek emergency medical attention immediately. Supportive measures and symptomatic treatment are mainstays of management; there is no specific antidote.

Storage

Store at room temperature (20–25°C or 68–77°F), in a tightly closed container, away from light, moisture, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Dispose of unused medication via take-back programs or following FDA-recommended steps to prevent misuse.
