Trazodone hydrochloride tablets are not approved for use in pediatric patients [see Use in Specific Populations (8.4)] .
Indications and Usage
Trazodone hydrochloride tablets are indicated for the treatment of major depressive disorder (MDD) in adults.
Contraindications
Trazodone hydrochloride tablets are contraindicated in: • Patients taking, or within 14 days of stopping, monoamine oxidase inhibitors (MAOIs), including MAOIs such as linezolid or intravenous methylene blue, because of an increased risk of serotonin syndrome [see Warnings and Precautions (5.2), Drug Interactions (7.1)] .
Adverse Reactions
The following serious adverse reactions are described elsewhere in the labeling: Suicidal Thoughts and Behavior in Children, Adolescents and Young Adults [see Boxed Warning and Warnings and Precautions (5.1)] Serotonin Syndrome [see Warnings and Precautions (5.2)] Cardiac Arrythmias [see Warnings and Precautions (5.3)] Orthostatic Hypotension and Syncope [see Warnings and Precautions (5.4)] Increased Risk of Bleeding [see Warnings and Precautions (5.5)] Priapism [see Warnings and Precautions (5.6)] Activation of Mania or Hypomania [see Warnings and Precautions (5.7)] Discontinuation Syndrome [see Warnings and Precautions (5.8)] Potential for Cognitive and Motor Impairment [see Warnings and Precautions (5.9)] Angle-Closure Glaucoma [see Warnings and Precautions (5.10)] Hyponatremia [see Warnings and Precautions (5.11)]
Mechanism of Action
The mechanism of trazodone’s antidepressant action is not fully understood, but is thought to be related to its enhancement of serotonergic activity in the CNS. Trazodone is both a selective serotonin reuptake inhibitor (SSRI) and a 5HT2 receptor antagonist and the net result of this action on serotonergic transmission and its role in trazodone’s antidepressant effect is unknown.
Overdosage
Death from overdose has occurred in patients ingesting trazodone hydrochloride tablets and other CNS depressant drugs concurrently (alcohol; alcohol and chloral hydrate and diazepam; amobarbital; chlordiazepoxide; or meprobamate). The most severe reactions reported to have occurred with overdose of trazodone hydrochloride tablets alone have been priapism, respiratory arrest, seizures, ECG changes, including QT prolongation and syndrome of inappropriate antidiuretic hormone secretion (SIADH). The reactions reported most frequently have been drowsiness and vomiting. Overdosage may cause an increase in incidence or severity of any of the reported adverse reactions. There is no specific antidote for trazodone hydrochloride overdose. In managing overdosage, consider the possibility of multiple drug involvement.
