⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Take duloxetine delayed-release capsules once daily, with or without food. Swallow whole; do not crush, or chew, or open capsule ( 2.1 ) Indication Starting Dose Target Dose Maximum Dose MDD ( 2.2 ) 40 mg/day to 60 mg/day Acute Treatment: 40 mg/day (20 mg twice daily) to 60 mg/day (once daily or as 30 mg twice daily); Maintenance Treatment: 60 mg/day 120 mg/day GAD ( 2.3 ) Adults 60 mg/day 60 mg/day (once daily) 120 mg/day Geriatric 30 mg/day 60 mg/day (once daily) 120 mg/day Pediatrics (7 to 17 years of age) 30 mg/day 30 to 60 mg/day (once daily) 120 mg/day DPNP ( 2.4 ) 60 mg/day 60 mg/day (once daily) 60 mg/day FM ( 2.5 ) Adults 30 mg/day 60 mg/day (once daily) 60 mg/day Chronic Musculoskeletal Pain ( 2.6 ) 30 mg/day 60 mg/day (once daily) 60 mg/day Discontinuing duloxetine delayed-release capsules: Gradually reduce dosage to avoid discontinuation symptoms ( 2.8 , 5.7 )
2.1Important Administration Instructions Administer duloxetine delayed-release capsules orally (with or without meals) and swallow whole. Do not chew or crush, and do not open the delayed-release capsule and sprinkle its contents on food or mix with liquids because these actions might affect the enteric coating. If a dose of duloxetine delayed-release capsules are missed, take the missed dose as soon as it is remembered.
If it is almost time for the next dose, skip the missed dose and take the next dose at the regular time. Do not take two doses of duloxetine delayed-release capsules at the same time.
2.2Dosage for Treatment of Major Depressive Disorder in Adults The recommended starting dosage in adults with MDD is 40 mg/day (given as 20 mg twice daily) to 60 mg/day (given either once daily or as 30 mg twice daily). For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to duloxetine delayed-release capsules before increasing to 60 mg once daily. While a 120 mg/day dose was shown to be effective, there is no evidence that doses greater than 60 mg/day confer any additional benefits.
Periodically reassess to determine the need for maintenance treatment and the appropriate dosage for such treatment.
2.3Dosage for Treatment of Generalized Anxiety Disorder Recommended Dosage in Adults Less than 65 Years of Age For most adults less than 65 years of age with GAD, initiate duloxetine delayed-release capsules 60 mg once daily. For some patients, it may be desirable to start at 30 mg once daily for 1 week, to allow patients to adjust to duloxetine delayed-release capsules before increasing to 60 mg once daily. While a 120 mg once daily dosage was shown to be effective, there is no evidence that doses greater than 60 mg/day confer additional benefit.
Nevertheless, if a decision is made to increase the dosage beyond 60 mg once daily, increase dosage in increments of 30 mg once daily. Periodically reassess to determine the continued need for maintenance treatment and the appropriate dosage for such treatment. Recommended Dosage in Geriatric Patients In geriatric patients with GAD, initiate duloxetine delayed-release capsules at a dosage of 30 mg once daily for 2 weeks before considering an increase to the target dose of 60 mg/day.
Thereafter, patients may benefit from doses above 60 mg once daily. If a decision is made to increase the dose beyond 60 mg once daily, increase dose in increments of 30 mg once daily. The maximum dose studied was 120 mg per day.
Recommended Dosage in Pediatric Patients 7 to 17 Years of Age Initiate duloxetine delayed-release capsules in pediatric patients 7 to 17 years of age with GAD at a dosage of 30 mg once daily for 2 weeks before considering an increase to 60 mg once daily. The recommended dosages range is 30 to 60 mg once daily. Some patients may benefit from dosages above 60 mg once daily.
If a decision is made to increase the dose beyond 60 mg once daily, increase dosage in increments of 30 mg once daily. The maximum dose studied was 120 mg per day. 2.4…

Avoid use in patients with substantial alcohol use or evidence of chronic liver disease ( 5.2 ) Orthostatic Hypotension, Falls and Syncope : Consider dosage reduction or discontinuation if these events occur ( 5.3 ) Serotonin Syndrome: Increased risk when co-administered with other serotonergic agents (e.g., SSRIs, SNRIs, triptans), but also when taken alone.
If it occurs, discontinue duloxetine ( 5.4 ) Increased Risk of Bleeding : May increase the risk of bleeding events. Concomitant use of antiplatelet drugs and anticoagulants may increase this risk ( 5.5 , 7.4 , 8.1 ) Severe Skin Reactions: Severe skin reactions, including erythema multiforme and Stevens-Johnson Syndrome (SJS), can occur; Discontinue at the first appearance of blisters, peeling rash, mucosal erosions, or any other sign of hypersensitivity if no other etiology can be identified. ( 5.6 ) Activation of Mania or Hypomania : Prior to initiating, screen patients for personal or family history of bipolar disorder, mania, or hypomania ( 5.8 ) Angle-Closure Glaucoma : Has occurred in patients with untreated anatomically narrow angles treated with antidepressants.

5.1Suicidal Thoughts and Behaviors in Children, Adolescents, and Young Adults Patients with major depressive disorder (MDD), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. Suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide.
There has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. Pooled analyses of short-term placebo-controlled trials of antidepressant drugs (SSRIs and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) with major depressive disorder (MDD) and other psychiatric disorders.
Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction with antidepressants compared to placebo in adults aged 65 and older. The pooled analyses of placebo-controlled trials in children and adolescents with MDD, obsessive compulsive disorder (OCD), or other psychiatric disorders included a total of 24 short-term trials of 9 antidepressant drugs in over 4400 patients. The pooled analyses of placebo-controlled trials in adults with MDD or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients.
There was considerable variation in risk of suicidality among drugs, but a tendency toward an incr…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The stated frequencies of adverse reactions represent the proportion of patients who experienced, at least once, one treatment-emergent adverse reaction of the type listed. A reaction was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation.
Adverse Reactions in Adults Adult Clinical Trial Database The data described below reflect exposure to duloxetine delayed-release capsules in placebo-controlled adult trials for MDD (N=3779), GAD (N=1018), OA (N=503), CLBP (N=600), DPNP (N=906), and FM (N=1294). The age range in this pooled population was 17 to 89 years of age. In this pooled population, 66%, 61%, 61%, 43%, and 94% of adult patients were female; and 82%, 73%, 85%, 74%, and 86% of adult patients were Caucasian in the MDD, GAD, OA and CLBP, DPNP, and FM populations, respectively.
Most patients received duloxetine delayed-release capsules dosages of a total of 60 to 120 mg per day [see Clinical Studies ( 14 )] . The data below do not include results of the trial that evaluated the efficacy of duloxetine delayed-release capsules for the treatment of GAD in patients ≥ 65 years old (Study GAD-5) [see Clinical Studies ( 14.3 )] ; however, the adverse reactions observed in this geriatric population were generally similar to adverse reactions in the overall adult population. Adverse Reactions Leading to Treatment Discontinuation in Adult Placebo-Controlled Trials Major Depressive Disorder Approximately 8.4% (319/3779) of duloxetine -treated patients in placebo-controlled adult trials for MDD discontinued treatment due to an adverse reaction, compared with 4.6% (117/2536) of placebo-treated patients.
Nausea (duloxetine 1.1%, placebo 0.4%) was the only adverse reaction reported as a reason for discontinuation and considered to be drug-related (i.e., discontinuation occurring in at least 1% of the duloxetine -treated patients and at a rate of at least twice that of placebo-treated patients). Generalized Anxiety Disorder Approximately 13.7% (139/1018) of the duloxetine -treated patients in placebo-controlled adult trials for GAD…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Both CYP1A2 and CYP2D6 are responsible for duloxetine metabolism. Potent inhibitors of CYP1A2 should be avoided ( 7.1 ). Potent inhibitors of CYP2D6 may increase duloxetine concentrations ( 7.2 ). Duloxetine is a moderate inhibitor of CYP2D6 ( 7.9 ).
7.1Inhibitors of CYP1A2 When duloxetine 60 mg was co-administered with fluvoxamine 100 mg, a potent CYP1A2 inhibitor, to male subjects (n=14) duloxetine AUC was increased approximately 6-fold, the C max was increased about 2.5-fold, and duloxetine t 1/2 was increased approximately 3-fold. Other drugs that inhibit CYP1A2 metabolism include cimetidine and quinolone antimicrobials such as ciprofloxacin and enoxacin [see Warnings and Precautions ( 5.12 )] .
7.2Inhibitors of CYP2D6 Concomitant use of duloxetine (40 mg once daily) with paroxetine (20 mg once daily) increased the concentration of duloxetine AUC by about 60%, and greater degrees of inhibition are expected with higher doses of paroxetine. Similar effects would be expected with other potent CYP2D6 inhibitors (e.g., fluoxetine, quinidine) [see Warnings and Precautions ( 5.12 )] .
7.3Dual Inhibition of CYP1A2 and CYP2D6 Concomitant administration of duloxetine 40 mg twice daily with fluvoxamine 100 mg, a potent CYP1A2 inhibitor, to CYP2D6 poor metabolizer subjects (n=14) resulted in a 6-fold increase in duloxetine AUC and C max .
7.4Drugs that Interfere with Hemostasis (e.g., NSAIDs, Aspirin, and Warfarin) Serotonin release by platelets plays an important role in hemostasis. Epidemiological studies of the case-control and cohort design that have demonstrated an association between use of psychotropic drugs that interfere with serotonin reuptake and the occurrence of upper gastrointestinal bleeding have also shown that concurrent use of an NSAID or aspirin may potentiate this risk of bleeding. Altered anticoagulant effects, including increased bleeding, have been reported when SSRIs or SNRIs are co-administered with warfarin.
Concomitant administration of warfarin (2 to 9 mg once daily) under steady state conditions with duloxetine 60 or 120 mg once daily for up to 14 days in healthy subjects (n=15) did not significantly change INR from baseline (mean INR changes ranged from 0.05 to +0.07). The total warfarin (protein bound plus free drug) pharmacokinetics (AUC T,ss, C max,ss or t max,ss ) for both R- and S-warfarin were not altered by duloxetine. Because of the potential effect of duloxetine on platelets, patients receiving warfarin therapy should be carefully monitored when duloxetine is initiated or discontinued [see Warnings and Precautions ( 5.5 )] .
7.5Lorazepam Under steady-state conditions for duloxetine (60 mg Q 12 hours) and lorazepam (2 mg Q 12 hours), the pharmacokinetics of duloxetine were not affected by co-administration.
7.6Temazepam Under steady-state conditions for duloxetine (20 mg qhs) and temazepam (30 mg qhs), the pharmacokinetics of duloxetine were not affected by co-administration.
7.7Drugs that Affect Gastric Acidity Duloxetine has an enteric coating that resists dissolution until reaching a segment of the gastrointestinal tract where the pH exceeds 5.5. In extremely acidic conditions, duloxetine, unprotected by the enteric coating, may undergo hydrolysis to form naphthol. Caution is advised in using duloxetine in patients with conditions that may slow gastric emptying (e.g., some diabetics).
Drugs that raise the gastrointestinal pH may lead to an earlier release of duloxetine. However, co-administration of duloxetine with aluminum- and magnesium-containing antacids (51 mEq) or duloxetine with famotidine, had no significant effect on the rate or extent of duloxetine absorption after administration of a 40 mg oral dose. It is unknown whether the concomitant administration of proton pump inhibitors affects duloxetine absorption [see Warnings and Precautions ( 5.14 )] .

8.1Pregnancy Risk Summary Data from a postmarketing retrospective cohort study indicate that use of duloxetine in the month before delivery may be associated with an increased risk of postpartum hemorrhage. Data from published literature and from a postmarketing retrospective cohort study have not identified a clear drug-associated risk of major birth defects or other adverse developmental outcomes (see Data) . There are risks associated with untreated depression and fibromyalgia in pregnancy, and with exposure to SNRIs and SSRIs, including duloxetine, during pregnancy (see Clinical Considerations).
In rats and rabbits treated with duloxetine during the period of organogenesis, fetal weights were decreased but there was no evidence of developmental effects at doses up to 3 and 6 times, respectively, the maximum recommended human dose (MRHD) of 120 mg/day given to adolescents on a mg/m 2 basis. When duloxetine was administered orally to pregnant rats throughout gestation and lactation, pup weights at birth and pup survival to 1 day postpartum were decreased at a dose 2 times the MRHD given to adolescents on a mg/m 2 basis.
At this dose, pup behaviors consistent with increased reactivity, such as increased startle response to noise and decreased habituation of locomotor activity were observed. Post-weaning growth was not adversely affected. The estimated 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 Embryo/Fetal 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 that followed 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. Pregnant women with fibromyalgia are at increased risk for adverse maternal and infant outcomes including preterm premature rupture of membranes, preterm birth, small for gestational age, intrauterine growth restriction, placental disruption, and venous thrombosis.
It is not known if these adverse maternal and fetal outcomes are a direct result of fibromyalgia or other comorbid factors. Maternal Adverse Reactions Use of duloxetine in the month before delivery may be associated with an increased risk of postpartum hemorrhage [see Warnings and Precautions ( 5.5 )]. Fetal/Neonatal Adverse Reaction Neonates exposed to duloxetine and other SNRIs or SSRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding.
Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficul…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of duloxetine have been established for treatment of generalized anxiety disorder (GAD) in patients 7 to 17 years of age. The safety and effectiveness of duloxetine have not been established in pediatric patients with major depressive disorder (MDD), diabetic peripheral neuropathic pain, or chronic musculoskeletal pain. Antidepressants increased the risk of suicidal thoughts and behavior in pediatric patients.
Monitor all pediatric patients being treated with antidepressants for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of treatment, or at times of dosage changes [see Warnings and Precautions ( 5.1 )] . Perform regular monitoring of weight and growth in pediatric patients treated with duloxetine [see Adverse Reactions ( 6.1 )]. Generalized Anxiety Disorder Use of duloxetine for the treatment of GAD in patients 7 to 17 years of age is supported by one 10-week, placebo-controlled trial (GAD-6).
The study included 272 pediatric patients with GAD of which 47% were 7 to 11 years of age (53% were 12 to 17 years of age). Duloxetine demonstrated superiority over placebo as measured by greater improvement in the Pediatric Anxiety Rating Scale (PARS) for GAD severity score [see Clinical Studies ( 14.3 )]. The safety and effectiveness of duloxetine for the treatment of GAD in pediatric patients less than 7 years of age have not been established.
Fibromyalgia The safety and effectiveness of duloxetine for the treatment of fibromyalgia in patients less than 13 years of age have not been established. Major Depressive Disorder The safety and effectiveness of duloxetine have not been established in pediatric patients for the treatment of MDD. Efficacy of duloxetine was not demonstrated in two 10-week, placebo-controlled trials with 800 pediatric patients aged 7 to 17 years old with MDD (MDD-6 and MDD-7).
Neither duloxetine nor an active control (approved for treatment of pediatric MDD) was superior to placebo. The most frequently observed adverse reactions in the MDD pediatric clinical trials included nausea, headache, decreased weight, and abdominal pain. Decreased appetite and weight loss have been observed in association with the use of SSRIs and SNRIs.
Juvenile Animal Toxicology Data Duloxetine administration to young rats from post-natal day 21 (weaning) through post-natal day 90 (adult) resulted in decreased body weights that persisted into adulthood, but recovered when drug treatment was discontinued; slightly delayed (~1.5 days) sexual maturation in females, without any effect on fertility; and a delay in learning a complex task in adulthood, which was not observed after drug treatment was discontinued. These effects were observed at the high dose of 45 mg/kg/day (2 times the MRHD, for a child); the no-effect-level was 20 mg/kg/day (≈1 times the MRHD, for a child).
Additional pediatric use information is approved for Eli Lilly and Company, Inc.’s CYMBALTA (duloxetine) delayed-release capsules. However, due to Eli Lilly and Company Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.
🧓 Geriatric Use ▾
8.5Geriatric Use Geriatric Exposure in Premarketing Clinical Trials of Duloxetine Of the 2,418 patients in MDD trials, 6% (143) were 65 years of age or over. Of the 1041 patients in CLBP trials, 21% (221) were 65 years of age or over. Of the 487 patients in OA trials, 41% (197) were 65 years of age or over.
Of the 1,074 patients in the DPNP trials, 33% (357) were 65 years of age or over. Of the 1,761 patients in FM trials, 8% (140) were 65 years of age or over. In the MDD, GAD, DPNP, FM, OA, and CLBP studies, no overall differences in safety or effectiveness were generally observed between these patients and younger adult patients, and other reported clinical experience has not identified differences in responses between these geriatric and younger adult patients, but greater sensitivity of some older patients cannot be ruled out.
SSRIs and SNRIs, including duloxetine have been associated with clinically significant hyponatremia in geriatric patients, who may be at greater risk for this adverse reaction [see Warnings and Precautions ( 5.13 )] . In an analysis of data from all placebo-controlled-trials, duloxetine -treated patients reported a higher rate of falls compared to placebo-treated patients. The increased risk appears to be proportional to a patient’s underlying risk for falls.
Underlying risk appears to increase steadily with age. As geriatric patients tend to have a higher prevalence of risk factors for falls such as medications, medical comorbidities and gait disturbances, the impact of increasing age by itself on falls during duloxetine treatment is unclear. Falls with serious consequences including bone fractures and hospitalizations have been reported with duloxetine use [see Warnings and Precautions ( 5.3 ) and Adverse Reactions ( 6.1 )] .
The pharmacokinetics of duloxetine after a single dose of 40 mg were compared in healthy elderly females (65 to 77 years) and healthy middle-age females (32 to 50 years). There was no difference in the C max , but the AUC of duloxetine was somewhat (about 25%) higher and the half-life about 4 hours longer in the elderly females. Population pharmacokinetic analyses suggest that the typical values for clearance decrease by approximately 1% for each year of age between 25 to 75 years of age; but age as a predictive factor only accounts for a small percentage of between-patient variability.
Dosage adjustment based on the age of the adult patient is not necessary.
🆘 Overdosage ▾
10 OVERDOSAGE
10.1Signs and Symptoms In postmarketing experience, fatal outcomes have been reported for acute duloxetine overdoses, primarily with mixed overdoses, but also with duloxetine only, including 1000 mg of duloxetine (approximately 8.3 times the maximum recommended dosage). Signs and symptoms of overdose (duloxetine alone or with mixed drugs) included somnolence, coma, serotonin syndrome, seizures, syncope, tachycardia, hypotension, hypertension, and vomiting.
10.2Management of Overdose There is no specific antidote to a duloxetine overdosage, but if serotonin syndrome ensues, specific treatment (such as with cyproheptadine and/or temperature control) may be considered. In case of acute overdose with duloxetine, treatment should consist of those general measures employed in the management of overdose with any drug, such as assuring an adequate airway, oxygenation, and ventilation and monitoring cardiac rhythm and vital signs. Gastric lavage with a large-bore orogastric tube with appropriate airway protection, if needed, may be indicated if performed soon after ingestion or in symptomatic patients.
Induction of emesis is not recommended. Activated charcoal may be useful in limiting absorption of duloxetine from the gastrointestinal tract. Administration of activated charcoal has been shown to decrease duloxetine AUC and C max by an average of one-third, although some patients had a limited effect of activated charcoal.
Due to the large volume of distribution of duloxetine, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be beneficial. In managing overdose, the possibility of multiple drug involvement should be considered. A specific caution involves patients who overdose with duloxetine and tricyclic antidepressants.
In such a case, decreased clearance of the parent tricyclic and/or its active metabolite may increase the possibility of clinically significant sequelae and extend the time needed for close medical observation [see Warnings and Precautions ( 5.4 ) and Drug Interactions ( 7 )] . Consider contacting a poison control center (1-800-222-1222 or www.poison.org) for additional information on the treatment of overdosage.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Although the exact mechanisms of the antidepressant, central pain inhibitory and anxiolytic actions of duloxetine in humans are unknown, these actions are believed to be related to its potentiation of serotonergic and noradrenergic activity in the CNS.
12.2Pharmacodynamics Preclinical studies have shown that duloxetine is a potent inhibitor of neuronal serotonin and norepinephrine reuptake and a less potent inhibitor of dopamine reuptake. Duloxetine has no significant affinity for dopaminergic, adrenergic, cholinergic, histaminergic, opioid, glutamate, and GABA receptors in vitro . Duloxetine does not inhibit monoamine oxidase (MAO).
Duloxetine is in a class of drugs known to affect urethral resistance. [see Warnings and Precautions ( 5.15 )] . Cardiac Electrophysiology The effect of duloxetine 160 mg and 200 mg administered twice daily (2.7 and 3.3 times the maximum recommended dosage, respectively) to steady state was evaluated in a randomized, double-blinded, two-way crossover study in 117 healthy female adult subjects. No QT interval prolongation was detected.
Duloxetine appears to be associated with concentration-dependent but not clinically meaningful QT shortening.
12.3Pharmacokinetics Duloxetine has an elimination half-life of about 12 hours (range 8 to 17 hours) and its pharmacokinetics are dose proportional over the therapeutic range. Steady-state plasma concentrations are typically achieved after 3 days of dosing. Elimination of duloxetine is mainly through hepatic metabolism involving two P450 isozymes, CYP1A2 and CYP2D6.
Absorption After oral duloxetine administration, duloxetine hydrochloride is well absorbed. There is a median 2 hour lag until absorption begins (T lag ), with maximal plasma concentrations (C max ) of duloxetine occurring 6 hours post dose. There is a 3 hour delay in absorption and a one-third increase in apparent clearance of duloxetine after an evening dose as compared to a morning dose.
Effect of Food: Food does not affect the C max of duloxetine, but delays the time to reach peak concentration from 6 to 10 hours and it marginally decreases the extent of absorption (AUC) by about 10%. Distribution The apparent volume of distribution averages about 1640 L. Duloxetine is highly bound (>90%) to proteins in human plasma, binding primarily to albumin and α 1 -acid glycoprotein.
The interaction between duloxetine and other highly protein bound drugs has not been fully evaluated. Plasma protein binding of duloxetine is not affected by renal or hepatic impairment. Elimination Metabolism Biotransformation and disposition of duloxetine in humans have been determined following oral administration of 14 C-labeled duloxetine.
Duloxetine comprises about 3% of the total radiolabeled material in the plasma, indicating that it undergoes extensive metabolism to numerous metabolites. The major biotransformation pathways for duloxetine involve oxidation of the naphthyl ring followed by conjugation and further oxidation. Both CYP1A2 and CYP2D6 catalyze the oxidation of the naphthyl ring in vitro .
Metabolites found in plasma include 4-hydroxy duloxetine glucuronide and 5-hydroxy, 6-methoxy duloxetine sulfate. Excretion Many additional metabolites have been identified in urine, some representing only minor pathways of elimination. Only trace (<1% of the dose) amounts of unchanged duloxetine are present in the urine.
Most (about 70%) of the duloxetine dose appears in the urine as metabolites of duloxetine; about 20% is excreted in the feces. Duloxetine undergoes extensive metabolism, but the major circulating metabolites have not been shown to contribute significantly to the pharmacologic activity of duloxetine. Specific Populations Pediatric Patients Duloxetine steady-state plasma concentration was comparable in pediatric patients 7 to 17 years of age and adult patients.
The average steady-state duloxetine concentration was approximately 30% lower in this pediatri…

💬 Information for Patients ▾
17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Medication Guide). Suicidal Thoughts and Behaviors — Advise patients, their families, and their caregivers to look for the emergence of suicidal ideation and behavior, especially during treatment and when the dose is adjusted up or down and instruct them to report such symptoms to their healthcare provider [see Boxed Warning and Warnings and Precautions ( 5.1 )]. Administration — Advise patients to swallow duloxetine delayed-release capsules whole and to not chew, crush, or open the capsule (do not sprinkle contents on food or mixed with liquids) because these actions might affect the enteric coating.
Hepatotoxicity — Inform patients that severe liver problems, sometimes fatal, have been reported in patients treated with duloxetine delayed-release capsules. Instruct patients to talk to their healthcare provider if they develop itching, right upper belly pain, dark urine, or yellow skin/eyes while taking duloxetine delayed-release capsules, which may be signs of liver problems. Instruct patients to talk to their healthcare provider about their alcohol consumption.
Use of duloxetine delayed-release capsules with heavy alcohol intake may be associated with severe liver injury [see Warnings and Precautions ( 5.2 )]. Alcohol — Although duloxetine does not increase the impairment of mental and motor skills caused by alcohol, use of duloxetine concomitantly with heavy alcohol intake may be associated with severe liver injury [see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.15 )]. Orthostatic Hypotension, Falls and Syncope — Advise patients of the risk of orthostatic hypotension, falls and syncope, especially during the period of initial use and subsequent dose escalation, and in association with the use of concomitant drugs that might potentiate the orthostatic effect of duloxetine [see Warnings and Precautions ( 5.3 )].
Serotonin Syndrome — Caution patients about the risk of serotonin syndrome with the concomitant use of duloxetine delayed-release capsules and other serotonergic agents including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, tryptophan, amphetamines, and St. John’s Wort [see Contraindications ( 4 ), Warnings and Precautions ( 5.4 ), and Drug Interactions ( 7.14 )]. Advise patients of the signs and symptoms associated with serotonin syndrome that 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 changes (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination), seizures, and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Caution patients to seek medical care immediately if they experience these symptoms.
