2 DOSAGE AND 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.

9 DRUG ABUSE AND DEPENDENCE 9.1 Controlled Substance Trazodone hydrochloride is not a controlled substance. 9.2 Abuse Although trazodone hydrochloride has not been systematically studied in preclinical or clinical studies for its potential for abuse, no indication of drug-seeking behavior was seen in the clinical studies with trazodone hydrochloride.

10 OVERDOSAGE Death from overdose has occurred in patients ingesting trazodone 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 alone have been priapism, respiratory arrest, seizures, and ECG changes, including QT prolongation. 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. Consider contacting the Poison Help line 1-888-222-1222 or a medical toxicologist for additional overdose management recommendations.

7 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) ] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action 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. 12.2 Pharmacodynamics Preclinical studies have shown that trazodone selectively inhibits neuronal reuptake of serotonin (Ki = 367 nM) and acts as an antagonist at 5-HT-2A (Ki = 35.6 nM) serotonin receptors. Trazodone is also an antagonist at several other monoaminergic receptors including 5-HT2B (Ki = 78.4 nM), 5-HT2C (Ki = 224 nM), α1A (Ki = 153 nM), α2C (Ki = 155 nM) receptors and it is a partial agonist at 5- HT1A (Ki = 118 nM) receptor. Trazodone antagonizes alpha 1-adrenergic receptors, a property which may be associated with postural hypotension. 12.3 Pharmacokinetics No clinically significant difference in pharmacokinetics of trazodone was observed between RALDESY and immediate-release trazodone hydrochloride tablet administered under fed conditions. Absorption Peak plasma levels occur approximately one hour after administration under fed conditions. Effect of Food Ingestion of a high-fat meal with RALDESY lowers mean C max of trazodone by 31% and increases mean AUC by 8%. Median T max was similar between fed and fasted conditions. Distribution Trazodone is 89% to 95% protein bound in vitro at concentrations attained with therapeutic doses in humans. Metabolism In vitro studies in human liver microsomes show that trazodone is metabolized, via oxidative cleavage, to an active metabolite, m-chlorophenylpiperazine (mCPP) by CYP3A4. Other metabolic pathways that may be involved in the metabolism of trazodone have not been well characterized. Trazodone is extensively metabolized; less than 1% of an oral dose is excreted unchanged in the urine. Elimination The average terminal elimination half-life of RALDESY under fed state is 18 hours.

RALDESY can cause a type of eye problem called angle-closure glaucoma in people with certain eye conditions. You may want to undergo an eye examination to see if you are at risk and receive preventative treatment if you are. Call your healthcare provider if you have changes in your vision, eye pain, or swelling or redness in or around the eye. • Low sodium in your blood (hyponatremia). Low sodium levels in your blood that may be serious and may cause death, can happen during treatment with RALDESY. Elderly people and people who take certain medicines may be at greater risk for this. Signs and symptoms may include: ◦ headache ◦ confusion ◦ difficulty concentrating ◦ weakness and unsteadiness on your feet, which can lead to falls ◦ memory changes ◦ talking more or faster than usual In more severe or sudden cases, signs and symptoms include: ◦ seeing or hearing things that are not real ◦ coma (hallucinations) ◦ stopping breathing (respiratory arrest) to falls ◦ fainting ◦ seizures The most common side effects of RALDESY include: • swelling • tiredness • blurred vision • diarrhea • fainting • stuffy nose • sleepiness • weight loss These are not all of the possible side effects of RALDESY.

8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants during pregnancy. Healthcare providers should encourage patients to enroll by calling the National Pregnancy Registry for Antidepressants at 1-866-961-2388 or visiting online at https://womensmentalhealth.org/research/pregnancyregistry/antidepressants/ . Risk Summary Published prospective cohort studies, case series, and case reports over several decades with trazodone hydrochloride tablets use in pregnant women have not identified any drug-associated risks of major birth defects, miscarriage, or other adverse maternal or fetal outcomes (see Data) . There are risks associated with untreated depression in pregnancy (see Clinical Considerations ) . Trazodone hydrochloride has been shown to cause increased fetal resorption and other adverse effects on the fetus in the rat when given at dose levels approximately 7.3 to 11 times the maximum recommended human dose (MRHD) of 400 mg/day in adults on a mg/m 2 basis. There was also an increase in congenital anomalies in the rabbit at approximately 7.3 to 22 times the MRHD on a mg/m 2 basis (see Data) . The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryofetal risk Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. This finding is from a prospective, longitudinal study of 201 pregnant women with a history of major depressive disorder who were euthymic and taking antidepressants at the beginning of pregnancy. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum. Data Human Data While available studies cannot definitively establish the absence of risk, published data from prospective cohort studies, case series, and case reports over several decades have not identified an association with trazodone use during pregnancy and major birth defects, miscarriage, or other adverse maternal or fetal outcomes. All available studies have methodological limitations, including small sample size and inconsistent comparator groups. Animal Data No teratogenic effects were observed when trazodone was given to pregnant rats and rabbits during the period of organogenesis at oral doses up to 450 mg/kg/day. This dose is 11 and 22 times, in rats and rabbits, respectively, the maximum recommended human dose (MRHD) of 400 mg/day in adults on a mg/m 2 basis. Increased fetal resorption and other adverse effects on the fetus in rats at 7.3 to 11 times the MRHD and increase in congenital anomalies in rabbits at 7.3 to 22 times the MRHD on a mg/m 2 basis were observed. No further details on these studies are available. 8.2 Lactation Risk Summary Data from published literature report the transfer of trazodone into human milk. There are no data on the effect of trazodone on milk production. Limited data from postmarketing reports have not identified an association of adverse effects on the breastfed child. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for RALDESY and any potential adverse effects on the breastfed child from RALDESY or from the underlying maternal condition. 8.4 Pediatric Use Safety and effectiveness of RALDESY in the pediatric patients have not been established. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning , Warnings and Precautions (5.1) ]. 8.5 Geriatric Use Reported clinical literature and experience with trazodone has not identified differences in responses between geriatric and younger patients. However, as experience with trazodone hydrochloride in geriatric patients is limited, RALDESY should be used with caution in these patients. Serotonergic antidepressants have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse reaction [see Warnings and Precautions (5.11) ]. 8.6 Renal Impairment Trazodone has not been studied in patients with renal impairment. RALDESY should be used with caution in this population. 8.7 Hepatic Impairment Trazodone has not been studied in patients with hepatic impairment. RALDESY should be used with caution in this population.
