not to exceed 60 mg/day Dosages ≥60 mg/day have not been shown to offer additional benefits Major depressive disorder and generalized anxiety disorder: Acute episodes often necessitate several months of sustained therapy Diabetic peripheral neuropathic pain: Efficacy for 12 weeks has not been studied; if diabetes is complicated by renal disease, consider lower starting dosage with gradual increase to effective dosage Fibromyalgia: Efficacy for ≥12 weeks has not been studied; continue treatment on basis of individual patient response Chronic musculoskeletal pain: Efficacy for ≥13 weeks has not been studied Uncontrolled narrow-angle glaucoma: Use not recommended due to increased risk of mydriasis Constipation (10%) Dizziness (10%) Insomnia (10%) Diarrhea (9-10%) Anorexia (8%) Decreased appetite (7-8%) Abdominal pain (6%) Hyperhidrosis (6%) Increased sweating (6%) Agitation (5%) Nasopharyngitis (5%) Vomiting (3-5%) Male sexual dysfunction (2-5%) Abdominal pain (4%) Decreased libido (4%) Musculoskeletal pain (4%) Upper respiratory tract infection (URTI) (4%) Abnormal orgasm (3%) Agitation (3%) Anxiety (3%) Blurred vision (3%) Cough (3%) Influenza (3%) Muscle spasms (3%) Tremor (3%) Abnormal dreams (2%) Dyspepsia (2%) Hot flushes (2%) Nausea (2%) Oropharyngeal pain (2%) Palpitations (2%) Paresthesia (2%) Weight loss (2%) Yawning (2%) Dysuria ( General: Anaphylactic reaction, angioneurotic edema, hypersensitivity Cardiovascular: Hypertensive crisis, supraventricular arrhythmia, myocardial infarction, tachycardia, Takotsubo cardiomyopathy Endocrine: Galactorrhea, gynecologic bleeding, hyperglycemia, hyperprolactinemia Neurologic: Restless legs syndrome, seizures upon treatment discontinuance, extrapyramidal disorders Ophthalmic: Glaucoma Otic: Tinnitus (upon treatment discontinuance) Psychiatric: Aggression and anger (particularly early in treatment or after treatment discontinuance), hallucinations Musculoskeletal: Trismus, muscle spasm Skin: Serious skin reactions (eg, erythema multiforme and Stevens-Johnson syndrome) necessitating drug discontinuance or hospitalization, urticaria, rash Gastrointestinal: Colitis (microscopic or unspecified),cutaneous vasculitis (sometimes associated with systemic involvement), acute pancreatitis Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies These studies did not show an increase in the risk of suicidal thoughts and behavior with antidepressant use in patients 24 yr There was a reduction in risk with antidepressant use in patients ≥65 yr In patients of all ages who are started on antidepressant therapy, monitor closely for worsening, and for emergence of suicidal thoughts and behaviors Advise families and caregivers of the need for close observation and communication with the prescriber CYP1A2 inhibitors or thioridazine should not be coadministered Use caution in severe renal impairment, ESRD Heavy alcohol use Suicidality; monitor for clinical worsening and suicide risk, especially in children, adolescents and young adults (18-24 years) during early phases of treatment and alterations in dosage Serotonin syndrome or neuroleptic malignant syndrome-like reactions may occur; discontinue and initiate supportive therapy; closely monitor patients concomitantly receiving triptans, antipsychotics and serotonin precursors Neonates exposed to serotonin-noreponephrine reuptake inhibitors (SNRIs) or selective serotonin reuptake inhibitors (SSRIs) late in 3rd trimester of pregnancy have developed complications necessitating prolonged hospitalization, respiratory support, and tube feeding Screen patients for bipolar disorder; risk of mixed/manic episodes is increased in patients treated with antidepressants May cause activation of mania or hypomania Increased risk of hepatotoxicity, sometimes fatal; monitor for abdominal pain, hepatomegaly, elevations in hepatic transaminases exceeding 20 times upper limit of normal; jaundice; cholestatic jaundice with minimal elevations of hepatic transaminases have also been reported; use not recommended in patients with substantial alcohol use or chronic liver disease SSRIs and SNRIs may impair platelet aggregation and increase the risk of bleeding events, ranging from ecchymoses, hematomas, epistaxis, petechiae, and GI hemorrhage to life-threatening hemorrhage; concomitant use of aspirin, NSAIDs, warfarin, other anticoagulants, or other drugs known to affect platelet function may add to this risk Severe skin reactions (eg, erythema multiforme and Stevens-Johnson syndrome); discontinue at first appearance of blisters, peeling rash, mucosal erosions, or any other sign of hypersensitivity if no other etiology can be identified Orthostatic hypotension and syncope, especially during week 1 of therapy; monitor patients taking drugs that increase risk of orthostatic hypotension; consider dose reduction or discontinue therapy in patients who experience symptomatic orthostatic hypotension, falls and/or syncope Hyponatremia due to syndrome of inappropriate antidiuretic hormone (SIADH); cases of serum sodium Exact mechanism of action unknown; inhibits reuptake of serotonin and norepinephrine; weakly inhibits reuptake of dopamine; has no MAOI activity; has no significant activity for histaminergic H1 receptor or alpha2-adrenergic receptor The above information is provided for general informational and educational purposes only.

Treatment failure may lower patients' quality of life and increase their economic burden. Providing adequate analgesia for patients with moderate to severe pain may require the use of multiple medications, often at high dosages. This can lead to unwanted adverse effects, which can become intolerable for some patients. Chronic use of systemic NSAIDs is associated with multiple adverse effects, including gastrointestinal upset, gastric ulcer formation, renal dysfunction, and increased cardiovascular risk. While the use of opiate narcotics and related analgesics may be helpful for acute pain, chronic use of these medications can lead to dependence and/or abuse. Opiate drugs produce sedation, tolerance, constipation, and allergic and pseudoallergic reactions.
