1 Dosing Considerations General: During maintenance therapy, the dosage should be kept at the lowest effective level. 4 Drug-Drug Interactions, Tricyclic Antidepressants section).
Switching Patients to or from a Monoamine Oxidase Inhibitor (MAOI):
At least 14 days should elapse between discontinuation of an MAOI and initiation of therapy with Auro-Fluoxetine. In addition, at least 5 weeks, perhaps longer, should be allowed after stopping Auro-Fluoxetine before starting MAOI (see 2 CONTRAINDICATIONS section).
Discontinuation of Treatment:
When dosing is stopped, active drug substances will persist in the body for weeks. This should be borne in mind when starting or stopping treatment. Dosage tapering is unnecessary in most patients. Despite its long-half life, symptoms associated with the discontinuation of fluoxetine have been reported in clinical trials and post-marketing.
Patients should be monitored for these and other symptoms when discontinuing treatment, regardless of the indication for which Auro- Fluoxetine is being prescribed. Fluoxetine has been only rarely associated with such symptoms. 1 Adverse Reaction Overview).
2 Recommended Dose and Dosage Adjustment Depression: Initial Adult Dosage: The usual initial dosage is 20 mg administered once daily in the morning. A gradual dose increase should be considered only after a trial period of several weeks if the expected clinical improvement does not occur.
Dosage should not exceed a maximum of 60 mg per day.
Long Term:
The efficacy of fluoxetine in maintaining an antidepressant response for up to 38 weeks following 12 weeks of open-label acute treatment (50 weeks total) was demonstrated in a placebo-controlled trial. 1 Clinical Trial by Indication section).
Bulimia Nervosa:
Adult Dosage: The recommended dosage is 60 mg per day, although studies show that lower doses may also be efficacious. Electrolyte levels should be assessed prior to initiation of treatment.
Obsessive-Compulsive Disorder:
1 Adverse Reaction Overview Commonly Observed Adverse Events In clinical trials, the most commonly observed adverse events associated with the use of fluoxetine and not seen at an equivalent incidence among placebo treated patients were: central nervous system complaints, including headache, nervousness, insomnia, drowsiness, fatigue or asthenia, anxiety, tremor, and dizziness or lightheadedness; gastrointestinal complaints, including nausea, diarrhea, dry mouth and anorexia; and excessive sweating.
Adverse Events Leading to Discontinuation of Treatment Fifteen percent of approximately 4,000 patients who received fluoxetine in North American clinical trials discontinued treatment due to an adverse event. The more common events causing discontinuation from depression trials in adults and elderly, included: psychiatric, primarily nervousness, anxiety, and insomnia; digestive, primarily nausea; nervous system, primarily dizziness, asthenia, and headaches; skin, primarily rash and pruritus.
1% of fluoxetine treated patients discontinued treatment early because of adverse events. Anxiety and rash, at incidences of less than 2%, were the most frequently reported events. 2% of fluoxetine treated patients discontinued treatment early because of adverse events.
Insomnia, anxiety and rash, at incidences of less than 2%, were the most frequently reported events. , headache, insomnia, paresthesias, nervousness, anxiety, nausea, sweating, numbness, dizziness, jitteriness, asthenia, or other symptoms which may be of clinical significance).
The majority of these are mild and self–limiting. Fluoxetine has been only rarely associated with such symptoms. Plasma fluoxetine and norfluoxetine concentrations decrease gradually at the conclusion of therapy, which makes dose tapering unnecessary in most patients.
1 Dosing Considerations, Discontinuation of Treatment; and 7 WARNINGS AND PRECAUTIONS, General. Serious Adverse Reactions Suicidal thoughts and acts are far more common among depressed patients than in the general population. It is estimated that suicide is 22 to 36 times more prevalent in depressed persons than in the general population.

Auro-Fluoxetine Product Monograph Page 5 of 55 2 CONTRAINDICATIONS • Hypersensitivity - Auro-Fluoxetine is contraindicated in patients who are hypersensitive to this drug or to any ingredient in the formulation, including any non-medicinal ingredient, or component of the container.
For a complete listing, see 6 DOSAGE FORMS, STRENGTHS, COMPOSITION AND PACKAGING section. • Monoamine Oxidase Inhibitors – In patients receiving serotonin reuptake inhibitors (SSRIs) in combination with a monoamine oxidase inhibitor (MAOI), there have been reports of serious, sometimes fatal, reactions (including hyperthermia, rigidity, myoclonus, autonomic instability with possible rapid fluctuations of vital signs, and mental status changes that include extreme agitation progressing to delirium and coma).
These reactions have also been reported in patients who have recently discontinued SSRI treatment and then started treatment on an MAOI. , serotonin syndrome). Auro-Fluoxetine should not be used in combination with an MAOI (including the antibiotic linezolid and the thiazine dye methylthioninium chloride (methylene blue) which are less well-known examples of MAOIs) or within 14 days of discontinuing therapy with an MAOI.
Since fluoxetine and its major metabolite have very long elimination half-lives, at least 5 weeks should elapse after discontinuing treatment with Auro-Fluoxetine before starting an MAOI. Limited reports suggest that intravenously administered dantrolene or orally administered cyproheptadine may benefit patients experiencing such reactions.

The use of Auro- Fluoxetine during pregnancy should be considered only if the potential benefit justifies the potential risk to the fetus taking into account the risks associated with untreated depression.
1 Pregnant Women, Complications following late third trimester exposure to SSRIs). When treating pregnant women with Auro-Fluoxetine during the third trimester, the health professional should carefully consider the potential risks and benefits of treatment.
The health professional may consider tapering Auro-Fluoxetine in the third trimester. • Geriatrics (≥ 60 years of age): Fluoxetine was evaluated in depressed elderly patients only at a dosage of 20 mg/day. A lower or less frequent dosage may be effective and should be considered in elderly patients with concurrent disease or on multiple medications.

A comprehensive meta-analysis of pooled data from 17 double blind clinical trials in patients with major depressive disorder compared fluoxetine (n = 1765) with a tricyclic antidepressant (n = 731) or placebo (n = 569), or both. 6% for tricyclic antidepressants.
In countries where the drug has already been marketed, the following potentially serious adverse reactions have been reported; interactions with MAO inhibitors and possibly other drugs, allergic reactions, cardiovascular reactions, syndrome of inappropriate ADH secretion, and grand mal seizure.
Death and life-threatening events have been associated with some of these reactions, although causal relationship to fluoxetine has not necessarily been established. Post-marketing experience also confirms the profile of adverse reactions commonly reported during clinical trials with fluoxetine including allergic skin reactions.
2 Clinical Trial Adverse Reactions Clinical trials are conducted under very specific conditions. The adverse drug reaction rates observed in the clinical trials; therefore, may not reflect the rates observed in practice and should not be compared to the rates in the clinical trials of another drug.
Adverse drug reaction information from clinical trials may be useful in identifying and approximating rates of adverse drug reactions in real-world use. Multiple doses of fluoxetine had been administered to 10,782 patients with various diagnoses in US clinical trials as of May 8, 1995.
Adverse events were recorded by clinical investigators using descriptive terminology of their own choosing. , reduced) number of standardized event categories.
Adults:
In the tables and tabulations that follow, COSTART Dictionary terminology has been used to classify reported adverse events. The stated frequencies represent the proportion of individuals who experienced, at least once, a treatment-emergent adverse event of the type listed.
An event was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation. It is important to emphasize that events reported during therapy were not necessarily caused by it.
The prescriber should be aware that the figures in the tables and tabulations 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 health professional with some basis for estimating the relative contribution of drug and nondrug factors to the side effect incidence rate in the population studied.
