  Major Depressive Disorder

  Usual Initial Dosage

  Paroxetine tablets, USP 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 paroxetine tablets, USP 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 paroxetine tablets, USP 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 paroxetine tablets, USP 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

  Paroxetine tablets, USP should be administered as a single daily dose with or without food, usually in the morning. The recommended dose of paroxetine tablets, USP 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 paroxetine tablets, USP 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

  Paroxetine tablets, USP should be administered as a single daily dose with or without food, usually in the morning. The target dose of paroxetine tablets, USP 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 paroxetine tablets, USP. 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

  Paroxetine tablets, USP 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 paroxetine tablets, USP was demonstrated in patients dosed in a range of 20 to 60 mg/day. While the safety of paroxetine tablets, USP 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 paroxetine tablets, USP should remain on it. Although the efficacy of paroxetine tablets, USP 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

  Paroxetine tablets, USP should be administered as a single daily dose with or without food, usually in the morning. In clinical trials the effectiveness of paroxetine tablets, USP 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 paroxetine tablets, USP for periods of up to 24 weeks in patients with Generalized Anxiety Disorder who had responded while taking paroxetine tablets, USP 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

  Paroxetine tablets, USP 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 paroxetine tablets, USP 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 paroxetine tablets, USP should remain on it. Although the efficacy of paroxetine tablets, USP 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 adjustment 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 paroxetine tablets, USP and other SSRIs or SNRIs, late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding (see WARNINGS–Usage in Pregnancy). When treating pregnant women with paroxetine during the third trimester, the physician should carefully consider the potential risks and benefits of treatment.

  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 a Patient to or From a Monoamine Oxidase Inhibitor (MAOI) Intended to Treat Psychiatric Disorders

  At least 14 days should elapse between discontinuation of an MAOI intended to treat psychiatric disorders and initiation of therapy with paroxetine tablets, USP. Conversely, at least 14 days should be allowed after stopping paroxetine tablets, USP before starting an MAOI intended to treat psychiatric disorders (see CONTRAINDICATIONS).

  Use of Paroxetine Tablets, USP With Other MAOIs, Such as Linezolid or Methylene Blue

  Do not start paroxetine tablets, USP in a patient who is being treated with linezolid or intravenous methylene blue because there is increased risk of serotonin syndrome. In a patient who requires more urgent treatment of a psychiatric condition, other interventions, including hospitalization, should be considered (see CONTRAINDICATIONS).

  In some cases, a patient receiving therapy with paroxetine tablets, USP may require urgent treatment with linezolid or intravenous methylene blue. If acceptable alternatives to linezolid or intravenous methylene blue treatment are not available and the potential benefits of linezolid or intravenous methylene blue treatment are judged to outweigh the risk of serotonin syndrome in a particular patient, paroxetine tablets, USP should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for 2 weeks or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with paroxetine tablets, USP may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue (see WARNINGS).

  The risk of administering methylene blue by non-intravenous routes (such as oral tablets or by local injection) or in intravenous doses much lower than 1 mg/kg with paroxetine tablets, USP is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use (see WARNINGS).

  Discontinuation of Treatment With Paroxetine Tablets, USP

  Symptoms associated with discontinuation of paroxetine tablets, USP have been reported (see PRECAUTIONS–Discontinuation of Treatment With Paroxetine Tablets, USP). Patients should be monitored for these symptoms when discontinuing treatment, regardless of the indication for which paroxetine tablets, USP 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.
