What is the brand name for trazodone?
The most common brand name for trazodone is Desyrel [1]. However, it is also available under other brand names, and generic versions are widely accessible [3].
How does trazodone work?
Trazodone affects neurotransmitters in the brain, particularly serotonin, which plays a role in mood regulation [2]. It works by inhibiting the reuptake of serotonin and blocking certain serotonin receptors, which can help improve mood and reduce symptoms of depression [4].
When does trazodone patent expire?

What are the common side effects of trazodone?
Common side effects of trazodone can include drowsiness, dizziness, dry mouth, blurred vision, and constipation [6]. Less common but more serious side effects may include priapism (a prolonged erection), irregular heartbeat, and suicidal thoughts, especially in younger patients [6][7].
Can trazodone be used for insomnia?
While trazodone is approved for depression, it is frequently prescribed off-label at lower doses to treat insomnia, particularly sleep difficulties associated with depression [8]. Its sedative properties make it effective for promoting sleep [9].
Are there alternatives to trazodone for depression?
Yes, numerous alternatives exist for treating depression, including other classes of antidepressants such as selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), and bupropion. Non-pharmacological treatments like psychotherapy and lifestyle changes are also important [10].
How does trazodone compare to other antidepressants?
Compared to SSRIs, trazodone may have a different side effect profile, with a higher incidence of sedation and dizziness, but potentially lower rates of sexual dysfunction [11]. Its SARI mechanism also differentiates it from other antidepressant classes [4].
Who manufactures trazodone?
Trazodone is manufactured by various pharmaceutical companies. The original brand, Desyrel, was developed by Mead Johnson. Today, both branded and generic trazodone are produced by numerous manufacturers globally [3].
What is the typical dosage for trazodone?
Dosage varies significantly depending on the condition being treated. For depression, typical starting doses might be around 150 mg per day, which can be increased up to 400 mg or 600 mg per day, divided into doses. For insomnia, much lower doses, often 25 mg to 100 mg, are commonly used at bedtime [12].
