How it works

The mechanism of trazodone’s antidepressant action is unclear, 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.

Dosing overview

Starting dosage: 150 mg orally in divided doses daily. May be increased by 50 mg per day every three to four days. Maximum dosage: 400 mg per day in divided doses. Administer RALDESY shortly after a meal or light snack. When discontinuing RALDESY, gradually reduce dose.

Contraindications

RALDESY is 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. Concomitant use of monoamine oxidase inhibitors (MAOIs), or use within 14 days of stopping MAOIs.

Warnings and precautions

Boxed warning (suicidal thoughts and behaviors): Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors. RALDESY is not approved for use in pediatric patients. Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents (e.g., SSRI, SNRI, triptans), but also when taken alone. If it occurs, discontinue RALDESY and initiate supportive treatment. Cardiac Arrhythmias: Increases the QT interval. Avoid use with drugs that also increase the QT interval and in patients with risk factors for prolonged QT interval. Orthostatic Hypotension and Syncope: Warn patients of risk and symptoms of hypotension.

Warfarin: Monitor for increased or decreased prothrombin time. Table 3 displays clinically significant drug Interactions with RALDESY. Table 3: Clinically Significant Drug Interactions with RALDESY Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact: The concomitant use of MAOIs and serotonergic drugs including RALDESY increases the risk of serotonin syndrome. Intervention: RALDESY is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue.
