FLUOXETINE- fluoxetine hydrochloride tablet

Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of Major Depressive Disorder (MDD) and other psychiatric disorders. Anyone considering the use of fluoxetine tablet or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. Short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. Depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. Patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. Families and caregivers should be advised of the need for close observation and communication with the prescriber. Fluoxetine tablet is not approved for use in pediatric patients [ s ee Warnings and Precautions ( 5.1) and Use in Specific Populations ( 8.4)].
Fluoxetine tablets, USP are indicated for the treatment of premenstrual dysphoric disorder (PMDD) [see Clinical Studies ( 14.1)].
The effectiveness of fluoxetine tablets, USP in long-term use (that is, for more than 6 months) has not been systematically evaluated in placebo-controlled trials. The use of fluoxetine tablets, USP for extended periods should be periodically re-evaluated for the individual patient [ see Dosage and Administration ( 2.1)].
The recommended dose of fluoxetine tablets for the treatment of PMDD is 20 mg/day given continuously (every day of the menstrual cycle) or intermittently (defined as starting a daily dose 14 days prior to the anticipated onset of menstruation through the first full day of menses and repeating with each new cycle). The dosing regimen should be based on individual patient characteristics. In a study comparing continuous dosing of fluoxetine 20 and 60 mg/day to placebo, both doses were proven to be effective, but there was no statistically significant added benefit for the 60 mg/day compared with the 20 mg/day dose. Fluoxetine doses above 60 mg/day have not been systematically studied in patients with PMDD. The maximum fluoxetine dose should not exceed 80 mg/day [see Clinical Studies ( 14.1)] .
Systematic evaluation of fluoxetine tablets has shown that its efficacy in PMDD is maintained for periods of up to 6 months at a dose of 20 mg/day given continuously and up to 3 months at a dose of 20 mg/day given intermittently [see Clinical Studies ( 14.1)] . Patients should be periodically re-assessed to determine the need for continued treatment.
Treatment of Pregnant Women — PMDD does not exist in pregnancy. However, if there is a need to treat pregnant women with fluoxetine, the physician should carefully consider the potential risks and potential benefits of treatment. Neonates exposed to SSRIs or SNRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding [see Use in Specific Populations ( 8.1)] .
Symptoms associated with discontinuation of fluoxetine, SNRIs, and SSRIs, have been reported [see Warnings and Precautions ( 5.14)] .
2.4 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 fluoxetine tablets. Conversely, at least 5 weeks should be allowed after stopping fluoxetine tablets before starting an MAOI intended to treat psychiatric disorders [ see Contraindications ( 4.1)].
Do not start fluoxetine tablets in a patient who is being treated with linezolid or intravenous methylene blue because there is an 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 ( 4.1)].
In some cases, a patient already receiving fluoxetine tablets therapy 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 risks of serotonin syndrome in a particular patient, fluoxetine tablets should be stopped promptly, and linezolid or intravenous methylene blue can be administered. The patient should be monitored for symptoms of serotonin syndrome for five weeks or until 24 hours after the last dose of linezolid or intravenous methylene blue, whichever comes first. Therapy with fluoxetine tablets may be resumed 24 hours after the last dose of linezolid or intravenous methylene blue [see Warnings and Precautions ( 5.2)].
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 fluoxetine tablets is unclear. The clinician should, nevertheless, be aware of the possibility of emergent symptoms of serotonin syndrome with such use [see Warnings and Precautions ( 5.2)] .
- 10 mg tablet is a light cream to cream colored, flat round, uncoated tablets with beveled edges, debossed with “43” on one side and plain on other side.
- 20 mg tablet is a light yellow to yellow colored, flat round, uncoated tablets with beveled edges, debossed with “73” on one side and plain on other side.
The use of MAOIs intended to treat psychiatric disorders with fluoxetine tablet or within 5 weeks of stopping treatment with fluoxetine tablet is contraindicated because of an increased risk of serotonin syndrome. The use of fluoxetine tablet within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see Dosage and Administration ( 2.4) and Warnings and Precautions ( 5.2)].
Starting fluoxetine tablet in a patient who is being treated with MAOIs such as linezolid or intravenous methylene blue is also contraindicated because of an increased risk of serotonin syndrome [ see Dosage and Administration ( 2.5) and Warnings and Precautions ( 5.2)].
