Paxil (continued)

. . . Carcinogenesis, Mutagenesis, Impairment of Fertility: Carcinogenesis: Two-year  carcinogenicity studies were conducted in rodents given paroxetine in the diet at 1, 5, and  25 mg/kg/day (mice) and 1, 5, and 20 mg/kg/day (rats). These doses are up to 2.4 (mouse) and  3.9 (rat) times the maximum recommended human dose (MRHD) for major depressive disorder,  social anxiety disorder, GAD, and PTSD on a mg/m 2 basis. Because the MRHD for major  depressive disorder is slightly less than that for OCD (50 mg versus 60 mg), the doses used in  these carcinogenicity studies were only 2.0 (mouse) and 3.2 (rat) times the MRHD for OCD.  There was a significantly greater number of male rats in the high-dose group with reticulum cell  sarcomas (1/100, 0/50, 0/50, and 4/50 for control, low-, middle-, and high-dose groups, respectively) and a significantly increased linear trend across dose groups for the occurrence of  lymphoreticular tumors in male rats. Female rats were not affected. Although there was a  dose-related increase in the number of tumors in mice, there was no drug-related increase in the  number of mice with tumors. The relevance of these findings to humans is unknown.    Mutagenesis: Paroxetine produced no genotoxic effects in a battery of 5 in vitro and 2 in  vivo assays that included the following: Bacterial mutation assay, mouse lymphoma mutation  assay, unscheduled DNA synthesis assay, and tests for cytogenetic aberrations in vivo in mouse  bone marrow and in vitro in human lymphocytes and in a dominant lethal test in rats.    Impairment of Fertility: A reduced pregnancy rate was found in reproduction studies in  rats at a dose of paroxetine of 15 mg/kg/day, which is 2.9 times the MRHD for major depressive  disorder, social anxiety disorder, GAD, and PTSD or 2.4 times the MRHD for OCD on a mg/m 2  basis. Irreversible lesions occurred in the reproductive tract of male rats after dosing in toxicity  studies for 2 to 52 weeks. These lesions consisted of vacuolation of epididymal tubular  epithelium at 50 mg/kg/day and atrophic changes in the seminiferous tubules of the testes with  arrested spermatogenesis at 25 mg/kg/day (9.8 and 4.9 times the MRHD for major depressive  disorder, social anxiety disorder, and GAD; 8.2 and 4.1 times the MRHD for OCD and PD on a  mg/m 2 basis).  Pregnancy: Pregnancy Category D. See WARNINGS—Usage in Pregnancy: Teratogenic and  Nonteratogenic Effects.   Labor and Delivery: The effect of paroxetine on labor and delivery in humans is unknown.  Nursing Mothers: Like many other drugs, paroxetine is secreted in human milk, and caution  should be exercised when PAXIL is administered to a nursing woman.   Pediatric Use: Safety and effectiveness in the pediatric population have not been established  (see BOX WARNING and WARNINGS—Clinical Worsening and Suicide Risk). Three  placebo-controlled trials in 752 pediatric patients with MDD have been conducted with PAXIL,  and the data were not sufficient to support a claim for use in pediatric patients. Anyone  considering the use of PAXIL in a child or adolescent must balance the potential risks with the  clinical need.    In placebo-controlled clinical trials conducted with pediatric patients, the following adverse  events were reported in at least 2% of pediatric patients treated with PAXIL and occurred at a  rate at least twice that for pediatric patients receiving placebo: emotional lability (including selfharm, suicidal thoughts, attempted suicide, crying, and mood fluctuations), hostility, decreased  appetite, tremor, sweating, hyperkinesia, and agitation.    Events reported upon discontinuation of treatment with PAXIL in the pediatric clinical trials  that included a taper phase regimen, which occurred in at least 2% of patients who received  PAXIL and which occurred at a rate at least twice that of placebo, were: emotional lability  (including suicidal ideation, suicide attempt, mood changes, and tearfulness), nervousness,  dizziness, nausea, and abdominal pain (see Discontinuation of Treatment With PAXIL).  Geriatric Use: In worldwide premarketing clinical trials with PAXIL, 17% of patients treated  with PAXIL (approximately 700) were 65 years of age or older. Pharmacokinetic studies revealed a decreased clearance in the elderly, and a lower starting dose is recommended; there  were, however, no overall differences in the adverse event profile between elderly and younger  patients, and effectiveness was similar in younger and older patients (see CLINICAL  PHARMACOLOGY and DOSAGE AND ADMINISTRATION).  ADVERSE REACTIONS  Associated With Discontinuation of Treatment: Twenty percent (1,199/6,145) of patients  treated with PAXIL in worldwide clinical trials in major depressive disorder and 16.1%  (84/522), 11.8% (64/542), 9.4% (44/469), 10.7% (79/735), and 11.7% (79/676) of patients  treated with PAXIL in worldwide trials in social anxiety disorder, OCD, panic disorder, GAD,  and PTSD, respectively, discontinued treatment due to an adverse event. The most common  events (≥1%) associated with discontinuation and considered to be drug related (i.e., those events  associated with dropout at a rate approximately twice or greater for PAXIL compared to placebo)  included the following: Major  Depressive  Disorder OCD Panic Disorder  Social Anxiety  Disorder  Generalized  Anxiety Disorder  PTSD    PAXIL Placebo PAXIL Placebo PAXIL Placebo PAXIL Placebo PAXIL Placebo PAXIL Placebo  CNS               Somnolence 2.3% 0.7% —  1.9% 0.3% 3.4% 0.3% 2.0% 0.2% 2.8% 0.6%  Insomnia — — 1.7% 0% 1.3% 0.3% 3.1% 0%   — —  Agitation 1.1% 0.5% —        — —  Tremor 1.1% 0.3% —    1.7% 0%   1.0% 0.2%  Anxiety — — —    1.1% 0%   — —  Dizziness — — 1.5% 0%   1.9% 0% 1.0% 0.2% — —  Gastroin testinal               Constipation —  1.1% 0%       — —  Nausea 3.2% 1.1% 1.9% 0% 3.2% 1.2% 4.0% 0.3% 2.0% 0.2% 2.2% 0.6%  Diarrhea 1.0% 0.3% —           Dry mouth 1.0% 0.3% —        — —  Vomiting 1.0% 0.3% —    1.0% 0%   — —  Flatulence       1.0% 0.3%   — —  Other                Asthenia 1.6% 0.4% 1.9% 0.4%   2.5% 0.6% 1.8% 0.2% 1.6% 0.2%  Abnormal    ejaculation 1    1.6%    0%    2.1%    0%      4.9%    0.6%    2.5%    0.5%    —    —  Sweating 1.0% 0.3% —    1.1% 0% 1.1% 0.2% — —  Impotence 1 —  1.5% 0%       — —  Libido   Decreased          1.0%    0%      —    —  Where numbers are not provided the incidence of the adverse events in patients treated with PAXIL was not >1% or  was not greater than or equal to 2 times the incidence of placebo.  1. Incidence corrected for gender.    Commonly Observed Adverse Events: Major Depressive Disorder: The most  commonly observed adverse events associated with the use of paroxetine (incidence of 5% or  greater and incidence for PAXIL at least twice that for placebo, derived from Table 1) were:  Asthenia, sweating, nausea, decreased appetite, somnolence, dizziness, insomnia, tremor,  nervousness, ejaculatory disturbance, and other male genital disorders.     Obsessive Compulsive Disorder: The most commonly observed adverse events  associated with the use of paroxetine (incidence of 5% or greater and incidence for PAXIL at  least twice that of placebo, derived from Table 2) were: Nausea, dry mouth, decreased appetite,  constipation, dizziness, somnolence, tremor, sweating, impotence, and abnormal ejaculation.    Panic Disorder: The most commonly observed adverse events associated with the use of  paroxetine (incidence of 5% or greater and incidence for PAXIL at least twice that for placebo,  derived from Table 2) were: Asthenia, sweating, decreased appetite, libido decreased, tremor,  abnormal ejaculation, female genital disorders, and impotence. Social Anxiety Disorder: The most commonly observed adverse events associated with  the use of paroxetine (incidence of 5% or greater and incidence for PAXIL at least twice that for  placebo, derived from Table 2) were: Sweating, nausea, dry mouth, constipation, decreased  appetite, somnolence, tremor, libido decreased, yawn, abnormal ejaculation, female genital  disorders, and impotence.    Generalized Anxiety Disorder: The most commonly observed adverse events associated  with the use of paroxetine (incidence of 5% or greater and incidence for PAXIL at least twice  that for placebo, derived from Table 3) were: Asthenia, infection, constipation, decreased  appetite, dry mouth, nausea, libido decreased, somnolence, tremor, sweating, and abnormal  ejaculation.    Posttraumatic Stress Disorder: The most commonly observed adverse events associated  with the use of paroxetine (incidence of 5% or greater and incidence for PAXIL at least twice  that for placebo, derived from Table 3) were: Asthenia, sweating, nausea, dry mouth, diarrhea,  decreased appetite, somnolence, libido decreased, abnormal ejaculation, female genital disorders,  and impotence.  Incidence in Controlled Clinical Trials: The prescriber should be aware that the figures in  the tables following cannot be used to predict the incidence of side effects in the course of usual  medical practice where patient characteristics and other factors differ from those that prevailed in  the clinical trials. Similarly, the cited frequencies cannot be compared with figures obtained from  other clinical investigations involving different treatments, uses, and investigators. The cited  figures, however, do provide the prescribing physician with some basis for estimating the  relative contribution of drug and nondrug factors to the side effect incidence rate in the  populations studied.    Major Depressive Disorder: Table 1 enumerates adverse events that occurred at an  incidence of 1% or more among paroxetine-treated patients who participated in short-term  (6-week) placebo-controlled trials in which patients were dosed in a range of 20 mg to  50 mg/day. Reported adverse events were classified using a standard COSTART-based  Dictionary terminology. Table 1.

No new adverse events were observed in the group treated with 60 mg of  PAXIL compared to any of the other treatment groups. In a fixed-dose study comparing placebo and 10, 20, and 40 mg of PAXIL in the treatment of  panic disorder, there was no clear relationship between adverse events and the dose of PAXIL to  which patients were assigned, except for asthenia, dry mouth, anxiety, libido decreased, tremor,  and abnormal ejaculation. In flexible-dose studies, no new adverse events were observed in  patients receiving 60 mg of PAXIL compared to any of the other treatment groups.     In a fixed-dose study comparing placebo and 20, 40, and 60 mg of PAXIL in the treatment of  social anxiety disorder, for most of the adverse events, there was no clear relationship between  adverse events and the dose of PAXIL to which patients were assigned.    In a fixed-dose study comparing placebo and 20 and 40 mg of PAXIL in the treatment of  generalized anxiety disorder, for most of the adverse events, there was no clear relationship  between adverse events and the dose of PAXIL to which patients were assigned, except for the  following adverse events: Asthenia, constipation, and abnormal ejaculation.    In a fixed-dose study comparing placebo and 20 and 40 mg of PAXIL in the treatment of  posttraumatic stress disorder, for most of the adverse events, there was no clear relationship  between adverse events and the dose of PAXIL to which patients were assigned, except for  impotence and abnormal ejaculation.    Adaptation to Certain Adverse Events: Over a 4- to 6-week period, there was evidence  of adaptation to some adverse events with continued therapy (e.g., nausea and dizziness), but less  to other effects (e.g., dry mouth, somnolence, and asthenia).    Male and Female Sexual Dysfunction With SSRIs: Although changes in sexual desire,  sexual performance, and sexual satisfaction often occur as manifestations of a psychiatric  disorder, they may also be a consequence of pharmacologic treatment. In particular, some  evidence suggests that selective serotonin reuptake inhibitors (SSRIs) can cause such untoward  sexual experiences.     Reliable estimates of the incidence and severity of untoward experiences involving sexual  desire, performance, and satisfaction are difficult to obtain, however, in part because patients and  physicians may be reluctant to discuss them. Accordingly, estimates of the incidence of  untoward sexual experience and performance cited in product labeling, are likely to  underestimate their actual incidence.    In placebo-controlled clinical trials involving more than 3,200 patients, the ranges for the  reported incidence of sexual side effects in males and females with major depressive disorder,  OCD, panic disorder, social anxiety disorder, GAD, and PTSD are displayed in Table 5. Table 5. Incidence of Sexual Adverse Events in Controlled Clinical Trials   PAXIL  Placebo  n (males)  1446  1042  Decreased Libido  6-15%  0-5%  Ejaculatory Disturbance  13-28%  0-2%  Impotence 2-9% 0-3%  n (females)  1822  1340  Decreased Libido  0-9%  0-2%  Orgasmic Disturbance  2-9%  0-1%      There are no adequate and well-controlled studies examining sexual dysfunction with  paroxetine treatment.    Paroxetine treatment has been associated with several cases of priapism. In those cases with a  known outcome, patients recovered without sequelae.    While it is difficult to know the precise risk of sexual dysfunction associated with the use of  SSRIs, physicians should routinely inquire about such possible side effects.    Weight and Vital Sign Changes: Significant weight loss may be an undesirable result of  treatment with PAXIL for some patients but, on average, patients in controlled trials had minimal  (about 1 pound) weight loss versus smaller changes on placebo and active control. No significant  changes in vital signs (systolic and diastolic blood pressure, pulse and temperature) were  observed in patients treated with PAXIL in controlled clinical trials.    ECG Changes: In an analysis of ECGs obtained in 682 patients treated with PAXIL and  415 patients treated with placebo in controlled clinical trials, no clinically significant changes  were seen in the ECGs of either group.    Liver Function Tests: In placebo-controlled clinical trials, patients treated with PAXIL  exhibited abnormal values on liver function tests at no greater rate than that seen in  placebo-treated patients. In particular, the PAXIL-versus-placebo comparisons for alkaline  phosphatase, SGOT, SGPT, and bilirubin revealed no differences in the percentage of patients  with marked abnormalities.   Hallucinations: In pooled clinical trials of immediate-release paroxetine hydrochloride,  hallucinations were observed in 22 of 9089 patients receiving drug and 4 of 3187 patients  receiving placebo.   Other Events Observed During the Premarketing Evaluation of PAXIL: During its  premarketing assessment in major depressive disorder, multiple doses of PAXIL were  administered to 6,145 patients in phase 2 and 3 studies. The conditions and duration of exposure  to PAXIL varied greatly and included (in overlapping categories) open and double-blind studies,  uncontrolled and controlled studies, inpatient and outpatient studies, and fixed-dose, and titration  studies. During premarketing clinical trials in OCD, panic disorder, social anxiety disorder,  generalized anxiety disorder, and posttraumatic stress disorder, 542, 469, 522, 735, and 676  patients, respectively, received multiple doses of PAXIL. Untoward events associated with this  exposure were recorded by clinical investigators using terminology of their own choosing. Consequently, it is not possible to provide a meaningful estimate of the proportion of individuals  experiencing adverse events without first grouping similar types of untoward events into a  smaller number of standardized event categories.    In the tabulations that follow, reported adverse events were classified using a standard  COSTART-based Dictionary terminology. The frequencies presented, therefore, represent the  proportion of the 9,089 patients exposed to multiple doses of PAXIL who experienced an event  of the type cited on at least 1 occasion while receiving PAXIL. All reported events are included  except those already listed in Tables 1 to 3, those reported in terms so general as to be  uninformative and those events where a drug cause was remote. It is important to emphasize that  although the events reported occurred during treatment with paroxetine, they were not  necessarily caused by it.    Events are further categorized by body system and listed in order of decreasing frequency  according to the following definitions: Frequent adverse events are those occurring on 1 or more  occasions in at least 1/100 patients (only those not already listed in the tabulated results from  placebo-controlled trials appear in this listing); infrequent adverse events are those occurring in  1/100 to 1/1,000 patients; rare events are those occurring in fewer than 1/1,000 patients. Events  of major clinical importance are also described in the PRECAUTIONS section.    Body as a Whole: Infrequent: Allergic reaction, chills, face edema, malaise, neck pain;  rare: Adrenergic syndrome, cellulitis, moniliasis, neck rigidity, pelvic pain, peritonitis, sepsis,  ulcer.     Cardiovascular System: Frequent: Hypertension, tachycardia; infrequent: Bradycardia,  hematoma, hypotension, migraine, syncope; rare: Angina pectoris, arrhythmia nodal, atrial  fibrillation, bundle branch block, cerebral ischemia, cerebrovascular accident, congestive heart  failure, heart block, low cardiac output, myocardial infarct, myocardial ischemia, pallor,  phlebitis, pulmonary embolus, supraventricular extrasystoles, thrombophlebitis, thrombosis,  varicose vein, vascular headache, ventricular extrasystoles.    Digestive System: Infrequent: Bruxism, colitis, dysphagia, eructation, gastritis,  gastroenteritis, gingivitis, glossitis, increased salivation, liver function tests abnormal, rectal  hemorrhage, ulcerative stomatitis; rare: Aphthous stomatitis, bloody diarrhea, bulimia,  cardiospasm, cholelithiasis, duodenitis, enteritis, esophagitis, fecal impactions, fecal  incontinence, gum hemorrhage, hematemesis, hepatitis, ileitis, ileus, intestinal obstruction,  jaundice, melena, mouth ulceration, peptic ulcer, salivary gland enlargement, sialadenitis,  stomach ulcer, stomatitis, tongue discoloration, tongue edema, tooth caries.    Endocrine System: Rare: Diabetes mellitus, goiter, hyperthyroidism, hypothyroidism,  thyroiditis.    Hemic and Lymphatic Systems: Infrequent: Anemia, leukopenia, lymphadenopathy,  purpura; rare: Abnormal erythrocytes, basophilia, bleeding time increased, eosinophilia,  hypochromic anemia, iron deficiency anemia, leukocytosis, lymphedema, abnormal  lymphocytes, lymphocytosis, microcytic anemia, monocytosis, normocytic anemia,  thrombocythemia, thrombocytopenia.

There has been  a case report of an elevated phenytoin level after 4 weeks of PAXIL and phenytoin  coadministration. There has been a case report of severe hypotension when PAXIL was added to  chronic metoprolol treatment.  DRUG ABUSE AND DEPENDENCE  Controlled Substance Class: PAXIL is not a controlled substance.  Physical and Psychologic Dependence: PAXIL has not been systematically studied in  animals or humans for its potential for abuse, tolerance or physical dependence. While the  clinical trials did not reveal any tendency for any drug-seeking behavior, these observations were  not systematic and it is not possible to predict on the basis of this limited experience the extent to  which a CNS-active drug will be misused, diverted, and/or abused once marketed. Consequently,  patients should be evaluated carefully for history of drug abuse, and such patients should be  observed closely for signs of misuse or abuse of PAXIL (e.g., development of tolerance,  incrementations of dose, drug-seeking behavior).  OVERDOSAGE  Human Experience: Since the introduction of PAXIL in the United States, 342 spontaneous  cases of deliberate or accidental overdosage during paroxetine treatment have been reported  worldwide (circa 1999). These include overdoses with paroxetine alone and in combination with  other substances. Of these, 48 cases were fatal and of the fatalities, 17 appeared to involve  paroxetine alone. Eight fatal cases that documented the amount of paroxetine ingested were  generally confounded by the ingestion of other drugs or alcohol or the presence of significant  comorbid conditions. Of 145 non-fatal cases with known outcome, most recovered without  sequelae. The largest known ingestion involved 2,000 mg of paroxetine (33 times the maximum  recommended daily dose) in a patient who recovered.     Commonly reported adverse events associated with paroxetine overdosage include  somnolence, coma, nausea, tremor, tachycardia, confusion, vomiting, and dizziness. Other  notable signs and symptoms observed with overdoses involving paroxetine (alone or with other  substances) include mydriasis, convulsions (including status epilepticus), ventricular  dysrhythmias (including torsade de pointes), hypertension, aggressive reactions, syncope,  hypotension, stupor, bradycardia, dystonia, rhabdomyolysis, symptoms of hepatic dysfunction (including hepatic failure, hepatic necrosis, jaundice, hepatitis, and hepatic steatosis), serotonin  syndrome, manic reactions, myoclonus, acute renal failure, and urinary retention.   Overdosage Management: Treatment should consist of those general measures employed in  the management of overdosage with any drugs effective in the treatment of major depressive  disorder.    Ensure an adequate airway, oxygenation, and ventilation. Monitor cardiac rhythm and vital  signs. General supportive and symptomatic measures are also recommended. Induction of emesis  is not recommended. 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.     Activated charcoal should be administered. Due to the large volume of distribution of this  drug, forced diuresis, dialysis, hemoperfusion, and exchange transfusion are unlikely to be of  benefit. No specific antidotes for paroxetine are known.    A specific caution involves patients who are taking or have recently taken paroxetine who  might ingest excessive quantities of a tricyclic antidepressant. In such a case, accumulation of the  parent tricyclic and/or an active metabolite may increase the possibility of clinically significant  sequelae and extend the time needed for close medical observation (see PRECAUTIONS— Drugs Metabolized by Cytochrome CYP2D6).    In managing overdosage, consider the possibility of multiple drug involvement. The physician  should consider contacting a poison control center for additional information on the treatment of  any overdose. Telephone numbers for certified poison control centers are listed in the Physicians'  Desk Reference (PDR).  DOSAGE AND ADMINISTRATION  Major Depressive Disorder: Usual Initial Dosage: PAXIL should be administered as a  single daily dose with or without food, usually in the morning. The recommended initial dose is  20 mg/day. Patients were dosed in a range of 20 to 50 mg/day in the clinical trials demonstrating  the effectiveness of PAXIL in the treatment of major depressive disorder. As with all drugs  effective in the treatment of major depressive disorder, the full effect may be delayed. Some  patients not responding to a 20-mg dose may benefit from dose increases, in 10-mg/day  increments, up to a maximum of 50 mg/day. Dose changes should occur at intervals of at least  1 week.    Maintenance Therapy: There is no body of evidence available to answer the question of  how long the patient treated with PAXIL should remain on it. It is generally agreed that acute  episodes of major depressive disorder require several months or longer of sustained  pharmacologic therapy. Whether the dose needed to induce remission is identical to the dose  needed to maintain and/or sustain euthymia is unknown.    Systematic evaluation of the efficacy of PAXIL has shown that efficacy is maintained for  periods of up to 1 year with doses that averaged about 30 mg. Obsessive Compulsive Disorder: Usual Initial Dosage: PAXIL should be administered  as a single daily dose with or without food, usually in the morning. The recommended dose of  PAXIL in the treatment of OCD is 40 mg daily. Patients should be started on 20 mg/day and the  dose can be increased in 10-mg/day increments. Dose changes should occur at intervals of at  least 1 week. Patients were dosed in a range of 20 to 60 mg/day in the clinical trials  demonstrating the effectiveness of PAXIL in the treatment of OCD. The maximum dosage  should not exceed 60 mg/day.    Maintenance Therapy: Long-term maintenance of efficacy was demonstrated in a 6-month  relapse prevention trial. In this trial, patients with OCD assigned to paroxetine demonstrated a  lower relapse rate compared to patients on placebo (see CLINICAL PHARMACOLOGY— Clinical Trials). OCD is a chronic condition, and it is reasonable to consider continuation for a  responding patient. Dosage adjustments should be made to maintain the patient on the lowest  effective dosage, and patients should be periodically reassessed to determine the need for  continued treatment.  Panic Disorder: Usual Initial Dosage: PAXIL should be administered as a single daily dose  with or without food, usually in the morning. The target dose of PAXIL in the treatment of panic  disorder is 40 mg/day. Patients should be started on 10 mg/day. Dose changes should occur in  10-mg/day increments and at intervals of at least 1 week. Patients were dosed in a range of 10 to  60 mg/day in the clinical trials demonstrating the effectiveness of PAXIL. The maximum dosage  should not exceed 60 mg/day.    Maintenance Therapy: Long-term maintenance of efficacy was demonstrated in a 3-month  relapse prevention trial. In this trial, patients with panic disorder assigned to paroxetine  demonstrated a lower relapse rate compared to patients on placebo (see CLINICAL  PHARMACOLOGY—Clinical Trials). Panic disorder is a chronic condition, and it is reasonable  to consider continuation for a responding patient. Dosage adjustments should be made to  maintain the patient on the lowest effective dosage, and patients should be periodically  reassessed to determine the need for continued treatment.  Social Anxiety Disorder: Usual Initial Dosage: PAXIL should be administered as a single  daily dose with or without food, usually in the morning. The recommended and initial dosage is  20 mg/day. In clinical trials the effectiveness of PAXIL was demonstrated in patients dosed in a  range of 20 to 60 mg/day. While the safety of PAXIL has been evaluated in patients with social  anxiety disorder at doses up to 60 mg/day, available information does not suggest any additional  benefit for doses above 20 mg/day (see CLINICAL PHARMACOLOGY—Clinical Trials).    Maintenance Therapy: There is no body of evidence available to answer the question of  how long the patient treated with PAXIL should remain on it. Although the efficacy of PAXIL  beyond 12 weeks of dosing has not been demonstrated in controlled clinical trials, social anxiety  disorder is recognized as a chronic condition, and it is reasonable to consider continuation of  treatment for a responding patient. Dosage adjustments should be made to maintain the patient  on the lowest effective dosage, and patients should be periodically reassessed to determine the  need for continued treatment. Generalized Anxiety Disorder: Usual Initial Dosage: PAXIL should be administered as a  single daily dose with or without food, usually in the morning. In clinical trials the effectiveness  of PAXIL was demonstrated in patients dosed in a range of 20 to 50 mg/day. The recommended  starting dosage and the established effective dosage is 20 mg/day. There is not sufficient  evidence to suggest a greater benefit to doses higher than 20 mg/day. Dose changes should occur  in 10 mg/day increments and at intervals of at least 1 week.     Maintenance Therapy: Systematic evaluation of continuing PAXIL for periods of up to  24 weeks in patients with Generalized Anxiety Disorder who had responded while taking PAXIL  during an 8-week acute treatment phase has demonstrated a benefit of such maintenance (see  CLINICAL PHARMACOLOGY—Clinical Trials). Nevertheless, patients should be periodically  reassessed to determine the need for maintenance treatment.  Posttraumatic Stress Disorder: Usual Initial Dosage: PAXIL should be administered as  a single daily dose with or without food, usually in the morning. The recommended starting  dosage and the established effective dosage is 20 mg/day. In 1 clinical trial, the effectiveness of  PAXIL was demonstrated in patients dosed in a range of 20 to 50 mg/day. However, in a fixed  dose study, there was not sufficient evidence to suggest a greater benefit for a dose of 40 mg/day  compared to 20 mg/day. Dose changes, if indicated, should occur in 10 mg/day increments and at  intervals of at least 1 week.    Maintenance Therapy: There is no body of evidence available to answer the question of  how long the patient treated with PAXIL should remain on it. Although the efficacy of PAXIL  beyond 12 weeks of dosing has not been demonstrated in controlled clinical trials, PTSD is  recognized as a chronic condition, and it is reasonable to consider continuation of treatment for a  responding patient. Dosage adjustments should be made to maintain the patient on the lowest  effective dosage, and patients should be periodically reassessed to determine the need for  continued treatment.  Special Populations: Treatment of Pregnant Women During the Third Trimester:  Neonates exposed to PAXIL and other SSRIs or SNRIs, late in the third trimester have  developed complications requiring prolonged hospitalization, respiratory support, and tube  feeding (see WARNINGS). When treating pregnant women with paroxetine during the third  trimester, the physician should carefully consider the potential risks and benefits of treatment.  The physician may consider tapering paroxetine in the third trimester.     Dosage for Elderly or Debilitated Patients, and Patients With Severe Renal or  Hepatic Impairment: The recommended initial dose is 10 mg/day for elderly patients,  debilitated patients, and/or patients with severe renal or hepatic impairment. Increases may be  made if indicated. Dosage should not exceed 40 mg/day.  Switching Patients to or From a Monoamine Oxidase Inhibitor: At least 14 days  should elapse between discontinuation of an MAOI and initiation of therapy with PAXIL.  Similarly, at least 14 days should be allowed after stopping PAXIL before starting an MAOI.  Discontinuation of Treatment With PAXIL: Symptoms associated with discontinuation of  PAXIL have been reported (see PRECAUTIONS). Patients should be monitored for these symptoms when discontinuing treatment, regardless of the indication for which PAXIL is being  prescribed. A gradual reduction in the dose rather than abrupt cessation is recommended  whenever possible. If intolerable symptoms occur following a decrease in the dose or upon  discontinuation of treatment, then resuming the previously prescribed dose may be considered.  Subsequently, the physician may continue decreasing the dose but at a more gradual rate.   NOTE: SHAKE SUSPENSION WELL BEFORE USING.  HOW SUPPLIED  Tablets: Film-coated, modified-oval as follows:    10-mg yellow, scored tablets engraved on the front with PAXIL and on the back with 10.  NDC 0029-3210-13 Bottles of 30    20-mg pink, scored tablets engraved on the front with PAXIL and on the back with 20.  NDC 0029-3211-13 Bottles of 30  NDC 0029-3211-59 Bottles of 90  NDC 0029-3211-21 SUP 100s (intended for institutional use only)    30-mg blue tablets engraved on the front with PAXIL and on the back with 30.  NDC 0029-3212-13 Bottles of 30    40-mg green tablets engraved on the front with PAXIL and on the back with 40.  NDC 0029-3213-13 Bottles of 30    Store tablets between 15° and 30°C (59° and 86°F).  Oral Suspension: Orange-colored, orange-flavored, 10 mg/5 mL, in 250 mL white bottles.  NDC 0029-3215-48    Store suspension at or below 25°C (77°F).  PAXIL is a registered trademark of GlaxoSmithKline.      Medication Guide  PAXIL® (PAX-il) (paroxetine hydrochloride) Tablets and Oral Suspension  About Using Antidepressants in Children and Teenagers    What is the most important information I should know if my child is being prescribed an  antidepressant?    Parents or guardians need to think about 4 important things when their child is prescribed an  antidepressant:  1.  There is a risk of suicidal thoughts or actions  2.  How to try to prevent suicidal thoughts or actions in your child  3.  You should watch for certain signs if your child is taking an antidepressant  4.  There are benefits and risks when using antidepressants 1. There is a Risk of Suicidal Thoughts or Actions    Children and teenagers sometimes think about suicide, and many report trying to kill themselves.    Antidepressants increase suicidal thoughts and actions in some children and teenagers. But  suicidal thoughts and actions can also be caused by depression, a serious medical condition that  is commonly treated with antidepressants. Thinking about killing yourself or trying to kill  yourself is called suicidality or being suicidal.    A large study combined the results of 24 different studies of children and teenagers with  depression or other illnesses. In these studies, patients took either a placebo (sugar pill) or an  antidepressant for 1 to 4 months. No one committed suicide in these studies, but some patients  became suicidal. On sugar pills, 2 out of every 100 became suicidal. On the antidepressants, 4  out of every 100 patients became suicidal.    For some children and teenagers, the risks of suicidal actions may be especially high. These  include patients with  •  Bipolar illness (sometimes called manic-depressive illness)  •  A family history of bipolar illness  •  A personal or family history of attempting suicide  If any of these are present, make sure you tell your healthcare provider before your child takes an  antidepressant.    2. How to Try to Prevent Suicidal Thoughts and Actions    To try to prevent suicidal thoughts and actions in your child, pay close attention to changes in her  or his moods or actions, especially if the changes occur suddenly. Other important people in your  child’s life can help by paying attention as well (e.g., your child, brothers and sisters, teachers,  and other important people). The changes to look out for are listed in Section 3, on what to watch  for.    Whenever an antidepressant is started or its dose is changed, pay close attention to your child.  After starting an antidepressant, your child should generally see his or her healthcare provider:  •  Once a week for the first 4 weeks  •  Every 2 weeks for the next 4 weeks  •  After taking the antidepressant for 12 weeks  •  After 12 weeks, follow your healthcare provider’s advice about how often to come back  •  More often if problems or questions arise (see Section 3)    You should call your child’s healthcare provider between visits if needed. 1. There is a Risk of Suicidal Thoughts or Actions    Children and teenagers sometimes think about suicide, and many report trying to kill themselves.    Antidepressants increase suicidal thoughts and actions in some children and teenagers. But  suicidal thoughts and actions can also be caused by depression, a serious medical condition that  is commonly treated with antidepressants. Thinking about killing yourself or trying to kill  yourself is called suicidality or being suicidal.    A large study combined the results of 24 different studies of children and teenagers with  depression or other illnesses. In these studies, patients took either a placebo (sugar pill) or an  antidepressant for 1 to 4 months. No one committed suicide in these studies, but some patients  became suicidal. On sugar pills, 2 out of every 100 became suicidal. On the antidepressants, 4  out of every 100 patients became suicidal.    For some children and teenagers, the risks of suicidal actions may be especially high. These  include patients with  •  Bipolar illness (sometimes called manic-depressive illness)  •  A family history of bipolar illness  •  A personal or family history of attempting suicide  If any of these are present, make sure you tell your healthcare provider before your child takes an  antidepressant.    2. How to Try to Prevent Suicidal Thoughts and Actions    To try to prevent suicidal thoughts and actions in your child, pay close attention to changes in her  or his moods or actions, especially if the changes occur suddenly. Other important people in your  child’s life can help by paying attention as well (e.g., your child, brothers and sisters, teachers,  and other important people). The changes to look out for are listed in Section 3, on what to watch  for.    Whenever an antidepressant is started or its dose is changed, pay close attention to your child.  After starting an antidepressant, your child should generally see his or her healthcare provider:  •  Once a week for the first 4 weeks  •  Every 2 weeks for the next 4 weeks  •  After taking the antidepressant for 12 weeks  •  After 12 weeks, follow your healthcare provider’s advice about how often to come back  •  More often if problems or questions arise (see Section 3)    You should call your child’s healthcare provider between visits if needed. 3. You Should Watch for Certain Signs If Your Child is Taking an Antidepressant    Contact your child’s healthcare provider right away if your child exhibits any of the following  signs for the first time, or if they seem worse, or worry you, your child, or your child’s teacher:  •  Thoughts about suicide or dying  •  Attempts to commit suicide  •  New or worse depression  •  New or worse anxiety  •  Feeling very agitated or restless  •  Panic attacks  •  Difficulty sleeping (insomnia)  •  New or worse irritability  •  Acting aggressive, being angry, or violent  •  Acting on dangerous impulses  •  An extreme increase in activity and talking  •  Other unusual changes in behavior or mood    Never let your child stop taking an antidepressant without first talking to his or her healthcare  provider. Stopping an antidepressant suddenly can cause other symptoms.    4. There are Benefits and Risks When Using Antidepressants    Antidepressants are used to treat depression and other illnesses. Depression and other illnesses  can lead to suicide. In some children and teenagers, treatment with an antidepressant increases  suicidal thinking or actions. It is important to discuss all the risks of treating depression and also  the risks of not treating it. You and your child should discuss all treatment choices with your  healthcare provider, not just the use of antidepressants.    Other side effects can occur with antidepressants (see section below).    Of all the antidepressants, only fluoxetine (Prozac ®)* has been FDA approved to treat pediatric  depression.    For obsessive compulsive disorder in children and teenagers, FDA has approved only fluoxetine  (Prozac ®)*, sertraline (Zoloft®)*, fluvoxamine, and clomipramine (Anafranil®)*.    Your healthcare provider may suggest other antidepressants based on the past experience of your  child or other family members. Is this all I need to know if my child is being prescribed an antidepressant?    No. This is a warning about the risk for suicidality. Other side effects can occur with  antidepressants. Be sure to ask your healthcare provider to explain all the side effects of the  particular drug he or she is prescribing. Also ask about drugs to avoid when taking an  antidepressant. Ask your healthcare provider or pharmacist where to find more information.      *The following are registered trademarks of their respective manufacturers: Prozac ®/Eli Lilly  and Company; Zoloft ®/Pfizer Pharmaceuticals; Anafranil®/Mallinckrodt Inc.
