Trazodone is not a controlled substance, nor is it considered a narcotic. Instead, Trazodone is a prescription antidepressant medication indicated for major depressive disorder. It may also be used off-label for other health conditions. Though the abuse potential for this drug is low, it can still be dangerous if it’s not taken exactly as prescribed. Alternative treatments for depression exist, including lifestyle changes, relaxation techniques, and certain herbal supplements.
What Is Trazodone?
Trazodone is an FDA-approved drug used to treat major depressive disorder. It belongs to a class of medications known as serotonin receptor antagonists and reuptake inhibitors, or SARIs. [1] Trazodone works by moderating the balance of serotonin in the brain. The generic name for Trazodone is trazodone hydrochloride. Trazodone brand names include Desyrel, Oleptro, and Raldesy.
Off-Label Uses for Trazodone
Healthcare providers sometimes prescribe medications for conditions other than those for which they’re intended. This is an acceptable medical practice known as off-label use. Trazodone is FDA-approved to treat clinical depression, but it may also be used to treat other mental health conditions such as anxiety and schizophrenia. Other off-label uses may include: [2]
- Alzheimer’s disease
- Dementia
- Substance misuse
- Bulimia
- Fibromyalgia

What’s the Typical Dose of Trazodone?
There may be no typical dose of Trazodone, since dosage may depend on individual symptoms. Recommended Trazodone doses may vary depending on several factors, including the severity of your symptoms.
Your doctor may start you on a 150 mg dose per day. If depression doesn’t respond to treatment, the dose may be increased every few days in 50 mg increments.[3] The maximum dosage for outpatient use is 400 milligrams per day. Higher doses may be prescribed for hospitalized patients who are under the direct care of a medical professional.
It is important to follow the instructions provided by your healthcare provider precisely. Only take the amount of Trazodone prescribed, even if you feel like it’s not working. It can take two weeks or more for antidepressants to begin working. This includes both SSRIs and SARIs. Never stop taking Trazodone without first talking to your prescriber. Doing so could cause severe withdrawal symptoms.
