Dosage Considerations • Duloxetine (duloxetine delayed-release capsules) is not indicated for use in children under 18 years of age (see WARNINGS AND PRECAUTIONS: General: Potential Association with Behavioural and Emotional Changes, Including Self-Harm).
• Duloxetine may be administered with or without food; however, food may help reduce the incidence of initial nausea. Results from a well-controlled dose comparison study (N=647) have demonstrated that patients taking duloxetine delayed-release capsules 60 mg/day with food experienced similar rates of nausea as patients treated with duloxetine delayed-release capsules 30 mg/day with or without food.
• Duloxetine should be swallowed whole and should not be chewed or crushed, nor should the contents be sprinkled on food or mixed with liquids. All of these might affect the enteric coating. • All patients who participated in the chronic low back pain clinical trials had a clinical diagnosis of CLBP with pain present on most days for at least 6 months and no signs of radiculopathy or spinal stenosis (see CLINICAL TRIALS).
Recommended Dose and Dose Adjustment Adults:
Major Depressive Disorder The recommended dose is 60 mg once daily. A lower starting dose of 30 mg may be considered for tolerability reasons in some patients, with a target dose of 60 mg/day within 1-2 weeks. Therapeutic response is usually seen after 1-4 weeks of treatment.
There is no evidence that doses greater than 60 mg/day confer additional benefit (see CLINICAL TRIALS). Generalized Anxiety Disorder The recommended dose is 60 mg once daily. A lower starting dose of 30 mg may be considered for tolerability reasons in some patients, with a target dose of 60 mg/day within 1-2 weeks (see Dosage for Elderly Patients).
Therapeutic response is usually seen after 1-4 weeks of treatment. While a 120 mg once daily dose was shown to be safe and effective, there is no evidence that doses greater than 60 mg/day confer additional benefit and the higher dose is less well tolerated.
Daily doses above 120 mg have not been evaluated for safety or efficacy and are not recommended (see CLINICAL TRIALS). Neuropathic Pain Associated with Diabetic Peripheral Neuropathy The recommended dose is 60 mg once daily. A lower starting dose of 30 mg may be considered for tolerability reasons in some patients, with a target dose of 60 mg/day within 1-2 weeks.
Hypersensitivity Duloxetine (duloxetine delayed-release capsules) is contraindicated in patients with a known hypersensitivity to the drug or the other components of the product. Monoamine Oxidase Inhibitors (MAOIs) Duloxetine should not be used concomitantly with a monoamine oxidase inhibitor (MAOI), including the antibiotic linezolid and the thiazine dye methylthioninium chloride (methylene blue) which are less well-known examples of MAOIs, or within at least 14 days of discontinuing treatment with an MAOI.
Based on the half-life of duloxetine, at least 5 days should be allowed after stopping Duloxetine before starting an MAOI (see WARNINGS AND PRECAUTIONS: General: MAOIs). Hepatic Impairment Duloxetine is contraindicated in patients with any liver disease resulting in hepatic impairment (see WARNINGS and PRECAUTIONS: General: Hepatic Impairment; and DOSAGE AND ADMINISTRATION: Dosage for Patients with Hepatic Impairment).
Uncontrolled Narrow-Angle Glaucoma In clinical trials, duloxetine delayed-release capsules were associated with an increased risk of mydriasis; therefore, its use should be avoided in patients with uncontrolled narrow-angle glaucoma (see WARNINGS AND PRECAUTIONS: General: Ophthalmologic).
e. creatinine clearance <30 mL/min) or end-stage renal disease (see WARNINGS AND PRECAUTIONS: Renal Impairment). Thioridazine Concomitant use of Duloxetine and thioridazine is contraindicated (see WARNINGS AND PRECAUTIONS: General: Thioridazine).

WARNINGS AND PRECAUTIONS General Potential Association with Behavioural and Emotional Changes, Including Self-Harm ______________________________________________________________________________ Duloxetine Product Monograph Page 6 of 87 Pediatrics: Placebo-Controlled Clinical Trial Data • Recent analyses of placebo-controlled clinical trial safety databases from selective serotonin reuptake inhibitors (SSRIs) and other newer antidepressants suggest that use of these drugs in patients under the age of 18 may be associated with behavioural and emotional changes, including an increased risk of suicidal ideation and behaviour over that of placebo.

Efficacy of duloxetine delayed-release capsules have been demonstrated within the first week. Some patients may benefit from dosages above the recommended 60 mg once daily up to a maximum dose of 120 mg per day. While a 120 mg/day dose was shown to be safe and effective, there is no evidence that doses greater than 60 mg /day confer additional significant ______________________________________________________________________________ Duloxetine Product Monograph Page 46 of 87 benefit, and the higher dose is less well tolerated (see ADVERSE EVENTS, Table 3).
Daily doses above 120 mg have not been evaluated for safety or efficacy and are not recommended (see CLINICAL TRIALS). Fibromyalgia The recommended dose is 60 mg once daily. A lower starting dose of 30 mg may be considered for tolerability reasons in some patients, with a target dose of 60 mg/day within 1-2 weeks.
Some patients may respond within the first week. , 120 mg/day) confer additional benefit. Additionally, patients who do not respond to 60 mg/day may not respond to 120 mg/day (see CLINICAL TRIALS). Furthermore, doses higher than 60 mg/day are associated with more severe and frequent rate of adverse reactions (see ADVERSE REACTIONS).
Daily doses above 120 mg have not been evaluated for safety or efficacy and are not recommended (see CLINICAL TRIALS).
Chronic Low Back Pain:
The recommended dose is 60 mg once daily. A lower starting dose of 30 mg may be considered for tolerability reasons in some patients, with a target dose of 60 mg/day within 1-2 weeks. Some patients may respond within the first week. There is no evidence that higher doses confer additional benefit, even in patients who do not respond to a 60 mg dose, and higher doses are associated with a higher rate of adverse reactions.
Daily doses above 120 mg have not been evaluated for safety or efficacy and are not recommended (see CLINICAL TRIALS). Chronic Pain Associated with Osteoarthritis of the Knee The recommended dose is 60 mg once daily. A lower starting dose of 30 mg may be considered for tolerability reasons in some patients, with a target dose of 60 mg/day within 1-2 weeks.
Some patients may respond within the first week. Some patients may benefit from dosages above the recommended 60 mg once daily up to a maximum dose of 120 mg per day, although the higher dose has been associated with a higher rate of adverse reactions.
Daily doses above 120 mg have not been evaluated for safety or efficacy and are not recommended (see CLINICAL TRIALS). Maintenance/Continuation/Extended Treatment Major Depressive Disorder It is generally agreed that acute episodes of major depression require several months or longer of sustained pharmacologic therapy beyond response to the acute episode.
There is insufficient evidence available to answer the question of how long a patient should continue to be treated with Duloxetine. Patients should be periodically reassessed to determine the need for maintenance treatment and the appropriate dose for such treatment.
Generalized Anxiety Disorder During long-term therapy, the dosage should be maintained at the lowest effective level and patients should be periodically re-assessed to determine the need to continue treatment (see CLINICAL TRIALS).

• The small denominators in the clinical trials database, as well as the variability in placebo rates, preclude reliable conclusions on the relative safety profiles among these drugs.
Adults and Pediatrics:
Additional data • There are clinical trial and post-marketing reports with SSRIs and other newer antidepressants, in both pediatrics and adults, of severe agitation-type adverse events coupled with self-harm or harm to others. The agitation-type events include: akathisia, agitation, disinhibition, emotional lability, hostility, aggression, and depersonalization.
In some cases, the events occurred within several weeks of starting treatment. Rigorous clinical monitoring for suicidal ideation or other indicators of potential for suicidal behaviour is advised in patients of all ages. This includes monitoring for agitation-type emotional and behavioural changes.
An FDA meta-analysis of placebo-controlled clinical trials of antidepressant drugs in adult patients ages 18 to 24 years with psychiatric disorder showed an increased risk of suicidal behaviour with antidepressants compared to placebo.
Akathisia/Psychomotor Restlessness The use of SSRI’s and other newer antidepressants, including duloxetine, has been very rarely associated with the development of akathisia, which is characterized by a subjectively unpleasant or distressing restlessness and a need to move, often accompanied by an inability to sit or stand.
This is most likely to occur within the first few weeks of treatment. In patients who develop these symptoms, increasing the dose may be detrimental. Discontinuation Symptoms Patients currently taking SSRIs or newer antidepressants should NOT be discontinued abruptly, due to risk of discontinuation symptoms.
At the time that a medical decision is made to discontinue an SSRI or other newer antidepressant drug, a gradual reduction in the dose rather than an abrupt cessation is recommended (see WARNINGS AND PRECAUTIONS: Dependence: Discontinuation of Treatment; ADVERSE REACTIONS: Adverse Events Following Discontinuation of Treatment; and DOSAGE AND ADMINISTRATION: Discontinuation of Treatment).
Monoamine Oxidase Inhibitors (MAOIs):
In patients receiving a serotonin reuptake inhibitor in combination with a MAOI, there have been reports of serious, sometimes fatal, reactions including hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes that include extreme agitation progressing to delirium and coma.
These reactions have also ______________________________________________________________________________ Duloxetine Product Monograph Page 7 of 87 been reported in patients who have recently discontinued serotonin reuptake inhibitors and are then started on a MAOI.
Some cases presented with features resembling neuroleptic malignant syndrome. The effects of combined use of duloxetine delayed-release capsules (duloxetine hydrochloride) and MAOIs have not been evaluated in humans or animals. Therefore, because Duloxetine is an inhibitor of both serotonin and norepinephrine reuptake, it is recommended that Duloxetine not be used in combination with a MAOI, including the antibiotic linezolid and methylene blue, a surgical dye, or within at least 14 days of discontinuing treatment with a MAOI.
Based on the half-life of duloxetine, at least 5 days should be allowed after stopping Duloxetine before starting a MAOI (see CONTRAINDICATIONS: MAOIs; and DRUG INTERACTIONS).
Hepatic Impairment:
