Indications & Usage
RALDESY TM is indicated for the treatment of major depressive disorder (MDD) in adults. RALDESY is a selective serotonin reuptake inhibitor (SSRI) indicated for the treatment of major depressive disorder (MDD) in adults ( 1 ).
Dosage & Administration
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 ( 2.1 ). Administer RALDESY shortly after a meal or light snack ( 2.1 ). When discontinuing RALDESY, gradually reduce dose ( 2.5 ). 2.1 Recommended Dosage The initial dosage of RALDESY for the treatment of MDD in adults is 150 mg daily, taken orally, in divided doses. The dosage should be initiated at a low-dose and increased gradually, depending on clinical response and an tolerance. Occurrence of drowsiness may require the administration of a major portion of the daily dose at bedtime or a reduction of dosage [see Dosage and Administration (2.5) ] The dose may be increased by 50 mg daily every 3 to 4 days. The maximum recommended dosage for outpatients usually should not exceed 400 mg daily in divided doses. Inpatients (i.e., more severely depressed patients) may be given up to, but not in excess, of 600 mg daily in divided doses. Administer RALDESY orally after a meal or light snack [see Clinical Pharmacology (12.3) ]. 2.2 Screen for Bipolar Disorder Prior to Starting RALDESY Prior to initiating treatment with RALDESY or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.7) ]. 2.3 Switching to or from Monoamine Oxidase Inhibitor Antidepressant At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of RALDESY. In addition, at least 14 days must elapse after stopping RALDESY before starting an MAOI antidepressant [see Contraindications (4) , Warnings and Precautions (5.2) ]. 2.4 Dosage Recommendations for Concomitant Use with Strong CYP3A4 Inhibitors or Inducers Coadministration with Strong CYP3A4 Inhibitors Consider reducing RALDESY dose based on tolerability when RALDESY is coadministered with a strong CYP3A4 inhibitor [see Drug Interactions (7.1) ]. Coadministration with Strong CYP3A4 Inducers Consider increasing RALDESY dose based on therapeutic response when RALDESY is coadministered with a strong CYP3A4 inducer [see Drug Interactions (7.1) ]. 2.5 Discontinuation of Treatment with RALDESY Adverse reactions may occur upon discontinuation of RALDESY [see Warnings and Precautions (5.8) ]. Gradually reduce the dosage rather than stopping RALDESY abruptly whenever possible.
Warnings & Precautions
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 ( 5.2 ). 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 ( 5.3 ). Orthostatic Hypotension and Syncope: Warn patients of risk and symptoms of hypotension ( 5.4 ). Increased Risk of Bleeding: Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), other antiplatelet drugs, warfarin, and other anticoagulants may increase this risk ( 5.5 ). Priapism: Cases of painful and prolonged penile erections and priapism have been reported. Immediate medical attention should be sought if signs and symptoms of prolonged penile erections or priapism are observed ( 5.6 ). Activation of Mania or Hypomania: Screen for bipolar disorder and monitor for mania or hypomania ( 5.7 ). Potential for Cognitive and Motor Impairment: Has potential to impair judgment, thinking, and motor skills. Advise patients to use caution when operating machinery ( 5.9 ). Angle-Closure Glaucoma: Avoid use of antidepressants, including RALDESY, in patients with untreated anatomically narrow angles. ( 5.10 ). 5.1 Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and over 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1,000 patients treated are provided in Table 1. Table 1: Risk Differences of the Number of Cases of Suicidal Thoughts or Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients Age Range (years) Drug-Placebo Difference in Number of Patients of Suicidal Thoughts or Behaviors per 1,000 Patients Treated Increases Compared to Placebo <18 14 additional patients 18-24 5 additional patients Decreases Compared to Placebo 25-64 1 fewer patient ≥65 6 fewer patients It is unknown whether the risk of suicidal thoughts and behaviors in pediatric and young adult patients extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors. Monitor all antidepressant-treated patients for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing RALDESY, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors. 5.2 Serotonin Syndrome SSRIs, including RALDESY, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John’s Wort) and with drugs that impair metabolism of serotonin, i.e., MAOIs [see Contraindications (4) , Drug Interactions (7.1) ]. Serotonin syndrome can also occur when these drugs are used alone. Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, and coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea). The concomitant use of RALDESY with MAOIs is contraindicated. In addition, do not initiate RALDESY in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking RALDESY, discontinue RALDESY before initiating treatment with the MAOI [see Contraindications (4) , Drug Interactions (7.1) ]. Monitor all patients taking RALDESY for the emergence of serotonin syndrome. Discontinue treatment with RALDESY and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of RALDESY with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms. 5.3 Cardiac Arrhythmias Clinical studies indicate that trazodone hydrochloride may be arrhythmogenic in patients with preexisting cardiac disease. Arrhythmias identified include isolated PVCs, ventricular couplets, tachycardia with syncope, and torsade de pointes. Postmarketing reports, including torsade de pointes have been reported at doses of 100 mg or less with the immediate-release trazodone hydrochloride tablets. RALDESY should also be avoided in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes and/or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and the presence of congenital prolongation of the QT interval. RALDESY is not recommended for use during the initial recovery phase of myocardial infarction. Caution should be used when administering RALDESY to patients with cardiac disease and such patients should be closely monitored, since antidepressant drugs (including RALDESY) may cause cardiac arrhythmias [see Adverse Reactions (6.2) ] . Trazodone hydrochloride prolongs the QT/QT c interval. The use of RALDESY Should be avoided in patients with known QT prolongation or in combination with other drugs that are inhibitors of CYP3A4 (e.g., itraconazole, clarithromycin, voriconazole), or known to prolong QT interval including Class 1A antiarrhythmics (e.g., quinidine, procainamide) or Class 3 antiarrhythmics (e.g., amiodarone, sotalol), certain antipsychotic medications (e.g., ziprasidone, chlorpromazine, thioridazine), and certain antibiotics (e.g., gatifloxacin). Concomitant administration of drugs may increase the risk of cardiac arrhythmia [see Drug Interactions (7.1) ]. 5.4 Orthostatic Hypotension and Syncope Hypotension, including orthostatic hypotension and syncope has been reported in patients receiving trazodone hydrochloride. Concomitant use with an antihypertensive may require a reduction in the dose of the antihypertensive drug. 5.5 Increased Risk of Bleeding Drugs that interfere with serotonin reuptake inhibition, including RALDESY, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), other antiplatelet drugs, warfarin, and other anticoagulants may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding. Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages. Inform patients about the risk of bleeding associated with the concomitant use of RALDESY and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing RALDESY. 5.6 Priapism Cases of priapism (painful erections greater than 6 hours in duration) have been reported in males receiving trazodone hydrochloride tablets. Priapism, if not treated promptly, can result in irreversible damage to the erectile tissue. Males who have an erection lasting greater than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention [see Adverse Reactions (6.2) , Overdosage (10) ]. RALDESY should be used with caution in males who have conditions that might predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, or leukemia), or in men with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, or Peyronie’s disease). 5.7 Activation of Mania or Hypomania In patients with bipolar disorder, treating a depressive episode with RALDESY or another antidepressant may precipitate a mixed/manic episode. Activation of mania/hypomania has been reported in a small proportion of patients with major affective disorder who were treated with antidepressants. Prior to initiating treatment with RALDESY, screen patients for any personal or family history of bipolar disorder, mania, or hypomania [see Dosage and Administration (2.3) ] . 5.8 Discontinuation Syndrome Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [See Dosage and Administration (2.6) ]. 5.9 Potential for Cognitive and Motor Impairment RALDESY TM may cause somnolence or sedation and may impair the mental and/or physical ability required for the performance of potentially hazardous tasks. Patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that the drug treatment does not affect them adversely. 5.10 Angle-Closure Glaucoma The pupillary dilation that occurs following use of many antidepressant drugs including RALDESY may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Avoid use of antidepressants, including RALDESY, in patients with untreated anatomically narrow angles. 5.11 Hyponatremia Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including RALDESY. Cases with serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which can lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH). In patients with symptomatic hyponatremia, discontinue RALDESY and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs [see Use in Specific Populations (8.5) ] .
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 [see Warnings and Precautions (5.1) ] . RALDESY is not approved for use in pediatric patients [see Use in Specific Populations (8.4) ] . WARNING: SUICIDAL THOUGHTS and BEHAVIORS See full prescribing information for complete boxed warning. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients. Closely monitor for clinical worsening and emergence of suicidal thoughts and behaviors ( 5.1 ). RALDESY is not approved for use in pediatric patients ( 8.4 ).
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 [see Warnings and Precautions (5.2) , Drug Interactions (7.1) ]. Concomitant use of monoamine oxidase inhibitors (MAOIs), or use within 14 days of stopping MAOIs ( 4 ).
Adverse Reactions
The following serious adverse reactions are described elsewhere in the labeling: Suicidal Thoughts and Behaviors in Pediatric and Young Adults Patients [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) ] Most common adverse reactions (incidence ≥ 5% and twice that of placebo) are: edema, blurred vision, syncope, drowsiness, fatigue, diarrhea, nasal congestion, weight loss ( 6.1 ).

The safety of RALDESY for the treatment of MDD in adults is based on studies of trazodone hydrochloride tablets. Below is a display of adverse reactions of trazodone hydrochloride tablets from those studies.

Occasional sinus bradycardia has occurred in long-term studies. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of trazodone hydrochloride tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure: Blood and lymphatic system disorders: hemolytic anemia, leukocytosis Cardiac disorders: cardiospasm, congestive heart failure, conduction block, orthostatic hypotension and syncope, palpitations, bradycardia, atrial fibrillation, myocardial infarction, cardiac arrest, arrhythmia, ventricular ectopic activity, including ventricular tachycardia and QT prolongation. Prolonged QT interval, torsade de pointes, and ventricular tachycardia have been reported at doses of 100 mg per day or less [see Warnings and Precautions (5.3) ]. Endocrine disorders: inappropriate ADH syndrome Eye disorders: diplopia Gastrointestinal disorders: increased salivation, nausea/vomiting General disorders and administration site conditions: chills, edema, unexplained death, weakness Hepatobiliary disorders: cholestasis, jaundice, hyperbilirubinemia, liver enzyme alterations Investigations: increased amylase Metabolism and nutrition disorders: methemoglobinemia Nervous system disorders: aphasia, ataxia, cerebrovascular accident, extrapyramidal symptoms, grand mal seizures, paresthesia, tardive dyskinesia, vertigo Psychiatric disorders: abnormal dreams, agitation, anxiety, hallucinations, insomnia, paranoid reaction, psychosis, stupor Renal and urinary disorders: urinary incontinence, urinary retention Reproductive system and breast disorders: breast enlargement or engorgement, clitorism, lactation, priapism [see Warnings and Precautions (5.6) ] Respiratory, thoracic and mediastinal disorders: apnea Skin and subcutaneous tissue disorders: alopecia, hirsutism, leukonychia, pruritus, psoriasis, rash, urticaria Vascular disorders: vasodilation
Drug Interactions
CNS Depressants: RALDESY may enhance effects of alcohol, barbiturates, or other CNS depressants ( 7 ). CYP3A4 Inhibitors: Consider RALDESY dose reduction based on tolerability ( 2.5 , 7 ). CYP3A4 Inducers: Increase in RALDESY dosage may be necessary ( 2.5 , 7 ). Digoxin or Phenytoin: Monitor for increased digoxin or phenytoin serum levels ( 7 ). Warfarin: Monitor for increased or decreased prothrombin time ( 7 ). 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 [see Contraindications (4) , Dosage and Administration ( 2.3 , 2.4) , and Warnings and Precautions (5.2) ]. Other Serotonergic Drugs Clinical Impact: The concomitant use of serotonergic drugs, including RALDESY and other serotonergic drugs increases the risk of serotonin syndrome. Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during RALDESY initiation. If serotonin syndrome occurs, consider discontinuation of RALDESY and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2) ]. Antiplatelet Agents and Anticoagulants Clinical Impact: Serotonin release by platelets plays an important role in hemostasis. The concurrent use of an antiplatelet agent or anticoagulant with RALDESY may potentiate the risk of bleeding. Intervention: Inform patients of the increased risk of bleeding with the concomitant use of RALDESY and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio (INR) when initiating or discontinuing RALDESY [see Warnings and Precautions (5.5) ]. Strong CYP3A4 Inhibitors Clinical Impact: The concomitant use of RALDESY and strong CYP3A4 inhibitors increased the exposure of trazodone compared to the use of RALDESY alone. Intervention: If RALDESY is used with a potent CYP3A4 inhibitor, the risk of adverse reactions, including cardiac arrhythmias, may be increased and a lower dose of RALDESY should be considered [see Dosage and Administration (2.5) , Warnings and Precautions (5.3) ]. Strong CYP3A4 Inducers Clinical Impact: The concomitant use of RALDESY and strong CYP3A4 inducers decreased the exposure of trazodone compared to the use of RALDESY alone. Intervention: Patients should be closely monitored to see if there is a need for an increased dose of RALDESY when taking CYP3A4 inducers [see Dosage and Administration (2.5) ]. Digoxin and Phenytoin Clinical Impact: Digoxin and phenytoin are narrow therapeutic index drugs. Concomitant use of RALDESY can increase digoxin or phenytoin concentrations. Intervention: Measure serum digoxin or phenytoin concentrations before initiating concomitant use of RALDESY. Continue monitoring and reduce digoxin or phenytoin dose as necessary. Central Nervous System (CNS) Depressants Clinical Impact: RALDESY may enhance the response CNS depressants. Intervention: Patients should be counseled that RALDESY may enhance the response to alcohol, barbiturates, and other CNS depressants. QT Interval Prolongation Clinical Impact: Concomitant use of drugs that prolong the QT interval may add to the QT effects of RALDESY and increase the risk of cardiac arrhythmia. Intervention: Avoid the use of RALDESY in combination with other drugs known to prolong QTc [see Warnings and Precautions (5.3) ] .
