FULL PRESCRIBING INFORMATION WARNING: SUICIDAL THOUGHTS AND BEHAVIORS Antidepressnts incresed the risk of suicidl thoughts nd behvior in children, dolescents, nd young dults in short-term studies. These studies did not show n increse in the risk of suicidl thoughts nd behvior with ntidepressnt use in ptients over ge 24; there ws reduction in risk with ntidepressnt use in ptients ged 65 nd older [see Wrnings nd Precutions (5.1)]. In ptients of ll ges who re strted on ntidepressnt therpy monitor closely for clinicl worsening nd emergence of suicidl thoughts nd behviors. Advise fmilies nd cregivers of the need for close observtion nd communiction with the prescriber [see Wrnings nd Precutions (5.1) nd Ptient Counseling Informtion (17)]. 1 INDICATIONS AND USAGE 1.1 Mjor Depressive Disorder ( hydrochloride) extended-relese cpsules re indicted for the tretment of mjor depressive disorder (MDD). Efficcy ws estblished in three short-term (4, 8, nd 12 weeks) nd two long-term, mintennce trils. 1.2 Generlized Anxiety Disorder is indicted for the tretment of Generlized Anxiety Disorder (GAD). Efficcy ws estblished in two 8-week nd two 26-week plcebo-controlled trils. 1.3 Socil Anxiety Disorder is indicted for the tretment of Socil Anxiety Disorder (SAD), lso known s socil phobi. Efficcy ws estblished in four 12-week nd one 26-week, plcebo-controlled trils. 1.4 Pnic Disorder is indicted for the tretment of Pnic Disorder (PD), with or without gorphobi. Efficcy ws estblished in two 12-week plcebo-controlled trils. 2 DOSAGE AND ADMINISTRATION should be dministered in single dose with food, either in the morning or in the evening t pproximtely the sme time ech dy [see Clinicl Phrmcology (12.3)]. Ech cpsule should be swllowed whole with fluid nd not divided, crushed, chewed, or plced in wter or it my be dministered by crefully opening the cpsule nd sprinkling the entire contents on spoonful of pplesuce. This drug/food mixture should be swllowed immeditely without chewing nd followed with glss of wter to ensure complete swllowing of the pellets (spheroids). 2.1 Mjor Depressive Disorder For most ptients, the recommended strting dose for is 75 mg per dy, dministered in single dose. For some ptients, it my be desirble to strt t 37.5 mg per dy for 4 to 7 dys to llow new ptients to djust to the mediction before incresing to 75 mg per dy. Ptients not responding to the initil 75 mg per dy dose my benefit from dose increses to mximum of 225 mg per dy. Dose increses should be in increments of up to 75 mg per dy, s needed, nd should be mde t intervls of not less thn 4 dys, since stedy-stte plsm levels of nd its mjor metbolites re chieved in most ptients by dy 4 [see Clinicl Phrmcology (12.3)]. In the clinicl studies estblishing efficcy, upwrd titrtion ws permitted t intervls of 2 weeks or more. It should be noted tht, while the mximum recommended dose for modertely depressed outptients is lso 225 mg per dy for Effexor (immedite-relese), more severely depressed inptients in one study of the development progrm for tht product responded to men dose of 350 mg per dy (rnge of 150 to 375 mg per dy). Whether or not higher doses of re needed for more severely depressed ptients is unknown; however, the experience with doses higher thn 225 mg per dy is very limited. 2.2 Generlized Anxiety Disorder For most ptients, the recommended strting dose for is 75 mg per dy, dministered in single dose. For some ptients, it my be desirble to strt t 37.5 mg per dy for 4 to 7 dys to llow new ptients to djust to the mediction before incresing to 75 mg per dy. Ptients not responding to the initil 75 mg per dy dose my benefit from dose increses to mximum of 225 mg per dy. Dose increses should be in increments of up to 75 mg per dy, s needed, nd should be mde t intervls of not less thn 4 dys, since stedy-stte plsm levels of nd its mjor metbolites re chieved in most ptients by dy 4 [see Clinicl Phrmcology (12.3)]. 2.3 Socil Anxiety Disorder (Socil Phobi) The recommended dose is 75 mg per dy, dministered in single dose. There ws no evidence tht higher doses confer ny dditionl benefit. 2.4 Pnic Disorder The recommended strting dose is 37.5 mg per dy of for 7 dys. Ptients not responding to 75 mg per dy my benefit from dose increses to mximum of pproximtely 225 mg per dy. Dose increses should be in increments of up to 75 mg per dy, s needed, nd should be mde t intervls of not less thn 7 dys. 2.5 Switching Ptients from Effexor Tblets Depressed ptients who re currently being treted t therpeutic dose with Effexor (immedite relese) my be switched to t the nerest equivlent dose (mg per dy), e.g., 37.5 mg twice dy to 75 mg once dily. However, individul dosge djustments my be necessry. 2.6 Specific Popultions Ptients with Heptic Impirment The totl dily dose should be reduced by 50% in ptients with mild (Child-Pugh=5-6) to moderte (Child-Pugh=7-9) heptic impirment. In ptients with severe heptic impirment (Child-Pugh=10-15) or heptic cirrhosis, it my be necessry to reduce the dose by 50% or more [See Use in Specific Popultions ( 8.7)]. Ptients with Renl Impirment The totl dily dose should be reduced by 25% to 50% in ptients with mild (CLcr= 60-89 ml/min) or moderte (CLcr= 30-59 ml/min) renl impirment. In ptients undergoing hemodilysis or with severe renl impirment (CLcr < 30 ml/min), the totl dily dose should be reduced by 50% or more. Becuse there ws much individul vribility in clernce between ptients with renl impirment, individuliztion of dosge my be desirble in some ptients [see Use in Specific Popultions ( 8.7)]. 2.7 Mintennce Tretment There is no body of evidence vilble from controlled studies to indicte how long ptients with MDD, GAD, SAD, or PD should be treted with. It is generlly greed tht cute episodes of MDD require severl months or longer of sustined phrmcologicl therpy beyond response to the cute episode. /Effexor hve demonstrted continution of response in clinicl studies up to 52 weeks, t the sme dose t which ptients responded during the initil tretment [see Clinicl Studies (14.1)]. It is not known whether or not the dose of needed for mintennce tretment is identicl to the dose needed to chieve n initil response. Ptients should be periodiclly ressessed to determine the need for mintennce tretment nd the pproprite dose for such tretment. In ptients with GAD nd SAD, hs been shown to be effective in 6-month clinicl studies. The need for continuing mediction in ptients with GAD nd SAD who improve with tretment should be periodiclly ressessed. In clinicl study for PD, ptients continuing t the sme dose t which they responded during the initil 12 weeks of tretment experienced sttisticlly significntly longer time to relpse thn ptients rndomized to plcebo [see Clinicl Studies (14.4)]. The need for continuing mediction in ptients with PD who improve with tretment should be periodiclly ressessed. 2.8 Discontinuing A grdul reduction in the dose, rther thn brupt cesstion, is recommended whenever possible. In clinicl studies with, tpering ws chieved by reducing the dily dose by 75 mg t one-week intervls. Individuliztion of tpering my be necessry [see Wrnings nd Precutions (5.7)]. 2.9 Switching Ptients to or from Monomine Oxidse Inhibitor (MAOI) Intended to Tret Psychitric Disorders At lest 14 dys should elpse between discontinution of n MAOI (intended to tret psychitric disorders) nd initition of therpy with. In ddition, t lest 7 dys should be llowed fter stopping before strting n MAOI intended to tret psychitric disorders [see Contrindictions (4.2), Wrnings nd Precutions (5.2), nd Drug Interctions (7.2)]. Use of with other MAOIs such s Linezolid or Intrvenous Methylene Blue Do not strt in ptient who is being treted with linezolid or intrvenous methylene blue, becuse there is n incresed risk of serotonin syndrome. In ptient who requires more urgent tretment of psychitric condition, other interventions, including hospitliztion should be considered [see Contrindictions 4.2)]. In some cses, ptient lredy receiving therpy my require urgent tretment with linezolid or intrvenous methylene blue. If cceptble lterntives to linezolid or intrvenous methylene blue re not vilble nd the potentil benefits of linezolid or intrvenous methylene blue tretment re judged to outweigh the risks of serotonin syndrome in prticulr ptient, should be stopped promptly, nd linezolid or intrvenous methylene blue cn be dministered. Monitor the ptient for symptoms of serotonin syndrome for 7 dys or until 24 hours fter the lst dose of linezolid or intrvenous methylene blue, whichever comes first. Therpy with cn be resumed 24 hours fter the lst dose of linezolid or intrvenous methylene blue [see Wrnings nd Precutions (5.2)]. The risk of dministering methylene blue by non-intrvenous routes (such s orl tblets or by locl injection) or in intrvenous doses much lower thn 1 mg/kg concomitntly with is uncler. The clinicin should, nevertheless, be wre of the possibility of emergent symptoms of serotonin syndrome with such use [see Wrnings nd Precutions (5.2)]. 3 DOSAGE FORMS AND STRENGTHS ( hydrochloride) extended-relese cpsules re vilble in the following strengths: 37.5 mg cpsules (grey cp/pech body with W nd on the cp nd 37.5 on the body) 75 mg cpsules (pech cp nd body with W nd on the cp nd 75 on the body) 150 mg cpsules (drk ornge cp nd body with W nd on the cp nd 150 on the body) 4 CONTRAINDICATIONS 4.1 Hypersensitivity Hypersensitivity to hydrochloride, des succinte or to ny excipients in the formultion 4.2 Concomitnt Use with Monomine Oxidse Inhibitors (MAOIs) The use of MAOIs (intended to tret psychitric disorders) concomitntly with or within 7 dys of discontinuing tretment with is contrindicted becuse of n incresed risk of serotonin syndrome. The use of within 14 dys of discontinuing tretment with n MAOI (intended to tret psychitric disorders) is lso contrindicted [see Dosge nd Administrtion (2.9), Wrnings nd Precutions (5.2), nd Drug Interctions (7.2)]. Strting in ptient who is being treted with n MAOI such s linezolid or intrvenous methylene blue is lso contrindicted, becuse of n incresed risk of serotonin syndrome [see Dosge nd Administrtion (2.9), Wrnings nd Precutions (5.2), nd Drug Interctions (7.3)].
5 WARNINGS AND PRECAUTIONS 5.1 Suicidl Thoughts nd Behviors in Children, Adolescents, nd Young Adults Ptients with mjor depressive disorder (MDD), both dult nd peditric, my experience worsening of their depression nd/or the emergence of suicidl idetion nd behvior (suicidlity) or unusul chnges in behvior, whether or not they re tking ntidepressnt medictions, nd this risk my persist until significnt remission occurs. Suicide is known risk of depression nd certin other psychitric disorders, nd these disorders themselves re the strongest predictors of suicide. There hs been long-stnding concern, however, tht ntidepressnts my hve role in inducing worsening of depression nd the emergence of suicidlity in certin ptients during the erly phses of tretment. Pooled nlyses of short-term plcebo-controlled studies of ntidepressnt drugs (SSRIs nd others) showed tht these drugs increse the risk of suicidl thinking nd behvior (suicidlity) in children, dolescents, nd young dults (ges 18-24) with MDD nd other psychitric disorders. Short-term studies did not show n increse in the risk of suicidlity with ntidepressnts compred to plcebo in dults beyond ge 24; there ws reduction with ntidepressnts compred to plcebo in dults ged 65 nd older. The pooled nlyses of plcebo-controlled studies in children nd dolescents with MDD, Obsessive Compulsive Disorder (OCD), or other psychitric disorders included totl of 24 short-term studies of 9 ntidepressnt drugs in over 4,400 ptients. The pooled nlyses of plcebo-controlled studies in dults with MDD or other psychitric disorders included totl of 295 short-term studies (medin durtion of 2 months) of 11 ntidepressnt drugs in over 77,000 ptients. There ws considerble vrition in risk of suicidlity mong drugs, but tendency towrd n increse in the younger ptients for lmost ll drugs studied. There were differences in bsolute risk of suicidlity cross the different indictions, with the highest incidence in MDD. The risk differences (drug versus plcebo), however, were reltively stble within ge strt nd cross indictions. These risk differences (drug-plcebo difference in the number of cses of suicidlity per 1,000 ptients treted) re provided in Tble 1. Tble 1: Difference in the Number of Cses of Suicidlity per 1,000 Ptients Treted versus Plcebo Age Rnge Increses Compred to Plcebo < 18 14 dditionl cses 18-24 5 dditionl cses Decreses Compred to Plcebo 25-64 1 fewer cse 65 6 fewer cses No suicides occurred in ny of the peditric studies. There were suicides in the dult studies, but the number ws not sufficient to rech ny conclusion bout drug effect on suicide. It is unknown whether the suicidlity risk extends to longer term use, i.e., beyond severl months. However, there is substntil evidence from plcebo-controlled mintennce studies in dults with depression tht the use of ntidepressnts cn dely the recurrence of depression. All ptients being treted with ntidepressnts for ny indiction should be monitored ppropritely nd observed closely for clinicl worsening, suicidlity, nd unusul chnges in behvior, especilly during the initil few months of course of drug therpy, or t times of dose chnges, either increses or decreses. The following symptoms, nxiety, gittion, pnic ttcks, insomni, irritbility, hostility, ggressiveness, impulsivity, kthisi (psychomotor restlessness), hypomni, nd mni, hve been reported in dult nd peditric ptients being treted with ntidepressnts for MDD, s well s for other indictions, both psychitric nd nonpsychitric. Although cusl link between the emergence of such symptoms nd either the worsening of depression nd/or the emergence of suicidl impulses hs not been estblished, there is concern tht such symptoms my represent precursors to emerging suicidlity. Considertion should be given to chnging the therpeutic regimen, including possibly discontinuing the mediction, in ptients whose depression is persistently worse, or who re experiencing emergent suicidlity or symptoms tht might be precursors to worsening depression or suicidlity, especilly if these symptoms re severe, brupt in onset, or were not prt of the ptient s presenting symptoms. If the decision hs been mde to discontinue tretment, mediction should be tpered, s rpidly s is fesible, but with recognition tht brupt discontinution cn be ssocited with certin symptoms [see Wrnings nd Precutions (5.7) nd Dosge nd Administrtion (2.8)]. Fmilies nd cregivers of ptients being treted with ntidepressnts for MDD or other indictions, both psychitric nd nonpsychitric, should be lerted bout the need to monitor ptients for the emergence of gittion, irritbility, unusul chnges in behvior, nd the other symptoms described bove, s well s the emergence of suicidlity, nd to report such symptoms immeditely to helthcre providers. Such monitoring should include dily observtion by fmilies nd cregivers. Prescriptions for should be written for the smllest quntity of cpsules consistent with good ptient mngement, in order to reduce the risk of overdose. Screening Ptients for Bipolr Disorder A mjor depressive episode my be the initil presenttion of bipolr disorder. It is generlly believed (though not estblished in controlled studies) tht treting such n episode with n ntidepressnt lone my increse the likelihood of precipittion of mixed/mnic episode in ptients t risk for bipolr disorder. Whether ny of the symptoms described bove represent such conversion is unknown. However, prior to inititing tretment with n ntidepressnt, ptients with depressive symptoms should be dequtely screened to determine if they re t risk for bipolr disorder; such screening should include detiled psychitric history, including fmily history of suicide, bipolr disorder, nd depression. It should be noted tht is not pproved for use in treting bipolr depression. 5.2 Serotonin Syndrome The development of potentilly life-thretening serotonin syndrome hs been reported with SNRIs nd SSRIs, including lone, but prticulrly with concomitnt use of other serotonergic drugs (including triptns, tricyclic ntidepressnts, fentnyl, lithium, trmdol, tryptophn, buspirone, nd St. John s wort) nd with drugs tht impir metbolism of serotonin in prticulr, MAOIs, both those intended to tret psychitric disorders nd others, such s linezolid or intrvenous methylene blue). Serotonin syndrome symptoms my include mentl sttus chnges (e.g., gittion, hllucintions, delirium, com) utonomic instbility (e.g., tchycrdi, lbile blood pressure, hyperthermi, diphoresis, flushing, nd dizziness), neuromusculr symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexi, incoordintion); seizures nd gstrointestinl symptoms (e.g., nuse, vomiting, dirrhe). Ptients should be monitored for the emergence of serotonin syndrome. The concomitnt use of with MAOIs (intended to tret psychitric disorders) is contrindicted. should lso not be strted in ptient who is being treted with MAOIs such s linezolid or intrvenous methylene blue. All reports with methylene blue tht provided informtion on the route of dministrtion involved intrvenous dministrtion in the dose rnge of 1 mg/kg to 8 mg/kg. No reports involved the dministrtion of methylene blue by other routes (such s orl tblets or locl tissue injection) or t lower doses. There my be circumstnces when it is necessry to initite tretment with MAOI such s linezolid or intrvenous methylene blue in ptient tking. should be discontinued before inititing tretment with the MAOI [see Contrindictions (4.2), Dosge nd Administrtion (2.6), nd Drug Interctions (7.3)]. If concomitnt use of with other serotonergic drugs (e.g., triptns, tricyclic ntidepressnts, mirtzpine, fentnyl, lithium, trmdol, buspirone, tryptophn, or St. John s wort) is cliniclly wrrnted, creful observtion of the ptient is dvised, prticulrly during tretment initition nd dose increses [see Drug Interctions (7.3)]. Ptients should be mde wre of the potentil risk of serotonin syndrome. Tretment with nd ny concomitnt serotonergic gents should be discontinued immeditely if the bove events occur, nd supportive symptomtic tretment should be initited. 5.3 Elevtions in Blood Pressure In controlled trils, there were dose-relted increses in systolic nd distolic blood pressure, s well s cses of sustined hypertension [see Adverse Rections (6.2)]. Monitor blood pressure before inititing tretment with nd regulrly during tretment. Control pre-existing hypertension before inititing tretment with. Use cution in treting ptients with pre-existing hypertension or crdiovsculr or cerebrovsculr conditions tht might be compromised by increses in blood pressure. Sustined blood pressure elevtion cn led to dverse outcomes. Cses of elevted blood pressure requiring immedite tretment hve been reported with. Consider dose reduction or discontinution of tretment for ptients who experience sustined increse in blood pressure. Across ll clinicl studies with Effexor, 1.4% of ptients in the treted groups experienced 15 mm Hg increse in supine distolic blood pressure (SDBP ) 105 mm Hg, compred to 0.9% of ptients in the plcebo groups. Similrly, 1% of ptients in the treted groups experienced 20 mm Hg increse in supine systolic blood pressure (SSBP) with blood pressure 180 mm Hg, compred to 0.3% of ptients in the plcebo groups [see Tble 10 in Adverse Rections (6.2)]. tretment ws ssocited with sustined hypertension (defined s tretment-emergent SDBP 90 mm Hg nd 10 mm Hg bove bseline for three consecutive on-therpy visits [see Tble 11 in Adverse Rections (6.2)]. An insufficient number of ptients received men doses of over 300 mg per dy in clinicl studies to fully evlute the incidence of sustined increses in blood pressure t these higher doses. 5.4 Abnorml Bleeding SSRIs nd SNRIs, including, my increse the risk of bleeding events, rnging from ecchymoses, hemtoms, epistxis, petechie, nd gstrointestinl hemorrhge to life-thretening hemorrhge. Concomitnt use of spirin, Nonsteroidl Anti-Inflmmtory Drugs (NSAIDs), wrfrin, nd other nti-cogulnts or other drugs known to ffect pltelet function my dd to this risk. Cse reports nd epidemiologicl studies (cse-control nd cohort design) hve demonstrted n ssocition between use of drugs tht interfere with serotonin reuptke nd the occurrence of gstrointestinl bleeding. Cution ptients bout the risk of bleeding ssocited with the concomitnt use of nd NSAIDs, spirin, or other drugs tht ffect cogultion. 5.5 Angle-Closure Glucom The pupillry diltion tht occurs following use of mny ntidepressnt drugs including Effexor XR my trigger n ngle closure ttck in ptient with ntomiclly nrrow ngles who does not hve ptent iridectomy. 5.6 Activtion of Mni/Hypomni Mni or hypomni ws reported in treted ptients in the premrketing studies in MDD, SAD, nd PD (see Tble 2). Mni/hypomni hs lso been reported in smll proportion of ptients with mood disorders who were treted with other mrketed drugs to tret MDD. should be used cutiously in ptients with history of mni or hypomni.

Abrupt discontinution or dose reduction of t vrious doses hs been found to be ssocited with the ppernce of new symptoms, the frequency of which incresed with incresed dose level nd with longer durtion of tretment. Reported symptoms include gittion, norexi, nxiety, confusion, impired coordintion nd blnce, dirrhe, dizziness, dry mouth, dysphoric mood, fscicultion, ftigue, flu-like symptoms, hedches, hypomni, insomni, nuse, nervousness, nightmres, sensory disturbnces (including shock-like electricl senstions), somnolence, sweting, tremor, vertigo, nd vomiting. During mrketing of, other SNRIs, nd SSRIs, there hve been spontneous reports of dverse events occurring upon discontinution of these drugs, prticulrly when brupt, including the following: dysphoric mood, irritbility, gittion, dizziness, sensory disturbnces (e.g., presthesi, such s electric shock senstions), nxiety, confusion, hedche, lethrgy, emotionl lbility, insomni, hypomni, tinnitus, nd seizures. While these events re generlly self-limiting, there hve been reports of serious discontinution symptoms.
Ptients should be monitored for these symptoms when discontinuing tretment with Effexor XR. A grdul reduction in the dose, rther thn brupt cesstion, is recommended whenever possible. If intolerble symptoms occur following decrese in the dose or upon discontinution of tretment, then resuming the previously prescribed dose my be considered. Subsequently, the physicin my continue decresing the dose, but t more grdul rte [see Dosge nd Administrtion (2.8)]. 5.8 Seizures Seizures hve occurred with therpy., like mny ntidepressnts, should be used cutiously in ptients with history of seizures nd should be discontinued in ny ptient who develops seizures. [Must mitigte the risk: Risk fctors, concomitnt meds tht lower the seizure threshold.] 5.9 Hypontremi Hypontremi cn occur s result of tretment with SSRIs nd SNRIs, including. In mny cses, the hypontremi ppers to be the result of the Syndrome of Inpproprite Antidiuretic Hormone (SIADH) secretion. Cses with serum sodium lower thn 110 mmol/l hve been reported. Elderly ptients my be t greter risk of developing hypontremi with SSRIs nd SNRIs [see Use in Specific Popultions (8.5)]. Also, ptients tking diuretics, or those who re otherwise volumedepleted, my be t greter risk. Consider discontinution of in ptients with symptomtic hypontremi, nd institute pproprite medicl intervention. Signs nd symptoms of hypontremi include hedche, difficulty concentrting, memory impirment, confusion, wekness, nd unstediness, which my led to flls. Signs nd symptoms ssocited with more severe nd/or cute cses hve included hllucintion, syncope, seizure, com, respirtory rrest, nd deth. 5.10 Weight nd Height Chnges in Peditric Ptients Weight Chnges The verge chnge in body weight nd incidence of weight loss (percentge of ptients who lost 3.5% or more) in the plcebo-controlled peditric studies in MDD, GAD, nd SAD re shown in Tbles 3 nd 4. Tble 3: Averge Chnge in Body Weight (kg) From Beginning of Tretment in Peditric Ptients in Double-blind, Plcebo-controlled Studies of Indiction Plcebo (Durtion) MDD nd GAD (4 pooled studies, 8 weeks) -0.45 (n = 333) +0.77 (n = 333) SAD (16 weeks) -0.75 (n = 137) +0.76 (n = 148) Tble 4: Incidence (%) of Peditric Ptients Experiencing Weight Loss (3.5% or more) in Double-blind, Plcebo-controlled Studies of Indiction Plcebo (Durtion) MDD nd GAD (4 pooled studies, 8 weeks) 18 (n = 333) 3.6 (n = 333) SAD (16 weeks) 47 (n = 137) 14 (n = 148) p < 0.001 versus plcebo Weight loss ws not limited to ptients with tretment-emergent norexi [see Wrnings nd Precutions (5.11)]. The risks ssocited with longer term use were ssessed in n open-lbel MDD study of children nd dolescents who received for up to six months. The children nd dolescents in the study hd increses in weight tht were less thn expected, bsed on dt from ge- nd sex-mtched peers. The difference between observed weight gin nd expected weight gin ws lrger for children (< 12 yers old) thn for dolescents ( 12 yers old).
