Trazodone: Uses, Dosage, and Interaction Guide

When working with Trazodone, a serotonin antagonist and reuptake inhibitor prescribed for depression and insomnia. Also known as Desyrel, it helps lift mood and improve nighttime rest. Trazodone sits in the broader class of antidepressants, medications that target brain chemistry to ease depressive symptoms. Because it modulates serotonin, it shares a metabolic pathway with many other psychotropics, especially the CYP450 enzyme system, the liver’s primary drug‑metabolizing network. Understanding that connection explains why Trazodone can boost or blunt the effect of other drugs you might be taking.

One of the most common reasons people get Trazodone is for insomnia, difficulty staying asleep or falling asleep. Unlike traditional sleep meds, Trazodone works by gently calming the brain’s wake‑up signals while still offering an antidepressant effect. This dual action makes it a go‑to option for patients who need both mood support and better sleep. However, the dosage for insomnia is usually lower than the dose used for major depressive disorder, so tailoring the amount to your specific goal matters.

Key Points to Watch

First, always start low and go slow. A typical starting dose for sleep is 25‑50 mg taken at bedtime, while depression often begins at 150 mg spread across the day. Sudden jumps can increase the risk of side effects like dizziness, dry mouth, or the infamous "serotonin syndrome" when combined with other serotonergic drugs. Second, watch for drug interactions. Because Trazodone is metabolized by CYP3A4, inhibitors such as certain antibiotics or antifungals can raise its blood level, leading to amplified sedation. Conversely, CYP inducers like some anti‑seizure meds may lower its effectiveness.

Side effects deserve a quick look. The most frequent ones are mild: headache, nausea, and a feeling of light‑headedness when you stand up quickly (orthostatic hypotension). A less common but notable effect is priapism—persistent, painful erections that need immediate medical attention. If you notice any unusual changes, contact your provider right away. Monitoring is especially important during the first few weeks, when your body is still adjusting.

Beyond the basics, Trazodone’s role in treating other conditions is gaining attention. Some clinicians use it off‑label for anxiety, post‑traumatic stress, and even chronic pain, leveraging its calming effect on the central nervous system. The evidence is still evolving, but the common thread is the drug’s ability to modulate serotonin pathways, which influence mood, sleep, and pain perception.
