Generic Desyrel Information

Introduction

Desyrel is a prescription medication whose active ingredient is trazodone, an antidepressant belonging to the serotonin‑modulating class. It is primarily indicated for the treatment of major depressive disorder (MDD) and is also employed off‑label as a sedative for insomnia when lower doses are used. In Hong Kong, trazodone is regulated under the “Prescription Medicines” schedule, requiring a valid medical prescription for legal dispensing. The drug was originally launched by Allegra Pharmaceuticals (now part of the Warner Chilcott portfolio) and is marketed in various regions under several brand names, including Desyrel, Oleptro, and Trazorel.

What is Desyrel?

Desyrel is a brand‑name formulation of trazodone, a synthetic compound that acts on central nervous system serotonin pathways. While the brand name has been widely recognized in North America and parts of Asia, generic versions containing the identical active molecule are available worldwide. The medication is supplied as oral tablets of 25 mg, 50 mg, 100 mg, and 150 mg strengths. Its therapeutic classification is “Antidepressant – serotonin antagonist and reuptake inhibitor (SARI).” The original manufacturer, Allegra Pharmaceuticals, introduced Desyrel in the early 198s, and subsequent generic production has expanded access to the drug in markets such as Hong Kong.

How Desyrel Works

Trazodone exerts its antidepressant effect through a dual mechanism:

• Serotonin reuptake inhibition – the molecule blocks the serotonin transporter (SERT), increasing extracellular serotonin levels and enhancing mood‑regulating neurotransmission.
• 5‑HT₂A receptor antagonism – by occupying post‑synaptic 5‑HT₂A receptors, trazodone reduces anxiety, agitation, and sleep disturbances that often accompany depression.

The combined action results in a gradual improvement in depressive symptoms, typically observable after 2–4 weeks of consistent dosing. At lower doses (≤50 mg), the drug’s antihistaminic and α₁‑adrenergic blocking properties dominate, producing sedation useful for sleep initiation. The elimination half‑life of trazodone averages 5–9 hours, with metabolites cleared primarily via hepatic cytochrome P450 enzymes (CYP3A4, CYP2D6).

Conditions Treated with Desyrel

• Major Depressive Disorder (MDD) – FDA‑approved and endorsed by the Hong Kong Hospital Authority as a second‑line option when selective serotonin reuptake inhibitors (SSRIs) are ineffective or not tolerated.
• Insomnia (off‑label) – low‑dose trazodone is frequently prescribed to patients with comorbid depression and sleep disturbance, offering a non‑benzodiazepine alternative.
• Anxiety disorders (off‑label) – the 5‑HT₂ antagonism may alleviate generalized anxiety symptoms, although clinical evidence is limited compared with first‑line anxiolytics.

In Hong Kong, depressive disorders affect an estimated 5 % of adults, while insomnia prevalence exceeds 30 % in the elderly population, underscoring the clinical relevance of a medication capable of addressing both conditions.

Patient Groups Most Likely to Benefit

• Adults with treatment‑resistant depression – individuals who have not achieved remission with SSRIs or serotonin‑noradrenaline reuptake inhibitors (SNRIs).
• Patients requiring a sedating antidepressant – those whose depressive episode coexists with significant insomnia, especially when benzodiazepine use is contraindicated.
• Older adults with insomnia secondary to depression – low‑dose trazodone can improve sleep continuity without the strong dependence risk of hypnotic agents.

Contra‑indications or cautionary use include: patients with a history of severe cardiac conduction disorders, uncontrolled glaucoma, or those concurrently taking potent CYP3A4 inhibitors (e.g., ketoconazole) that may raise serum trazodone concentrations.

Risks, Side Effects, and Interactions

Common

• Drowsiness or sedation
• Dry mouth
• Dizziness, especially upon standing (orthostatic hypotension)
• Nausea or gastrointestinal upset
• Headache

Rare

• Priapism (prolonged penile erection) – requires immediate medical attention.
• Hyponatremia, particularly in elderly patients or those on diuretics.
• Elevated liver enzymes – monitor with prolonged therapy.

Serious

• Cardiac arrhythmias (QT prolongation) – heightened risk when combined with other QT‑prolonging drugs.
• Severe hypotension or syncope.
• Serotonin syndrome if used with other serotonergic agents (e.g., SSRIs, MAO inhibitors).

Drug–Drug Interactions

• CYP3A4 inhibitors (ketoconazole, erythromycin) → increase trazodone plasma levels, risk of toxicity.
• CYP3A4 inducers (rifampicin, carbamazepine) → reduce efficacy.
• Other serotonergic medications (SSRIs, SNRIs, tramadol, linezolid) → potentiate serotonin syndrome.
• Alcohol → additive CNS depression, should be avoided.

Patients should inform their healthcare provider of all concurrent medications, herbal supplements, and over‑the‑counter products.

Practical Use: Dosing, Missed Dose, Overdose

• Initial dosing for depression: 150 mg per day in divided doses (e.g., 50 mg three times daily), titrated upward to 300–400 mg/day based on clinical response and tolerability.
• Insomnia dosing: 25–50 mg taken 30 minutes before bedtime; higher doses may cause next‑day sedation.
• Missed dose: Take the forgotten dose as soon as remembered if at least 4 hours remain before the next scheduled dose; otherwise skip and continue the regular schedule. Do not double‑dose.
• Overdose management: Symptoms may include severe drowsiness, respiratory depression, cardiac arrhythmias, or coma. Immediate emergency medical care is essential; activated charcoal may be considered if presentation is early.
• Food & alcohol: Trazodone can be taken with or without food; however, a light snack may lessen gastrointestinal upset. Alcohol should be avoided due to synergistic sedation.

Renal or hepatic impairment warrants dose reduction and closer monitoring.

FAQ

• Is Desyrel available in both brand‑name and generic forms in Hong Kong?
  Yes. Desyrel is the original brand name, while numerous generic manufacturers produce trazodone tablets that contain the same active ingredient and meet the same regulatory standards. Generic versions are typically less expensive and are offered by our online pharmacy.

• What is the optimal time of day to take Desyrel for insomnia?
  For sleep‑inducing purposes, the medication should be taken 30 minutes before bedtime, on an empty stomach if possible, to promote rapid onset of sedation.

• Can Desyrel cause weight change?
  Weight gain or loss is not a common side effect of trazodone; however, individual responses vary, and any significant change in appetite or body weight should be discussed with a healthcare professional.

• How should Desyrel be stored at home?
  Store tablets at room temperature (15 °C–30 °C), away from direct sunlight, heat, and moisture. Keep the bottle tightly closed and out of reach of children.

• Are there special precautions for patients with cardiac disease?
  Yes. Because trazodone can affect cardiac conduction (QT prolongation and orthostatic hypotension), patients with known arrhythmias, heart block, or recent myocardial infarction should undergo ECG monitoring before initiating therapy.

• Is it safe to use Desyrel during pregnancy or breastfeeding?
  Trazodone is classified as Category C in the United States, indicating that risk cannot be ruled out. It should only be used if the potential benefit justifies the potential fetal risk, and breastfeeding mothers should consult a physician, as the drug is excreted in breast milk.

• Can Desyrel interact with over‑the‑counter sleep aids?
  Many OTC sleep aids contain antihistamines (e.g., diphenhydramine). Combined use may increase sedation and dizziness, so concurrent use should be avoided or closely monitored.

• What should I do if I experience priapism while on Desyrel?
  Priapism is a medical emergency. Seek immediate care; delayed treatment can result in permanent tissue damage. Do not wait for the episode to resolve spontaneously.
