It is essential for patients to continue with treatment exactly as directed to achieve desired therapeutic outcomes. What is the difference between generic and brand Prozac? In most patients, there is no significant difference between generic and brand Prozac fluoxetine. There is currently a generic equivalent available for Prozac, known as fluoxetine.
Food and Drug Administration FDA requires that generic medications be bioequivalent to the brand-name medication and, therefore, exert the same pharmacologic effects in the body. Generic medications are considered, by the FDA, to be therapeutically identical to the brand-name counterparts in dose, strength, route of administration, safety, efficacy and indication for use.
Generic medications will appear differently and may have different inactive ingredients, however, the labeling and directions for use remain the same. For most medications, generic equivalents are a lower-cost alternative to the more expensive brand-name medication, and the majority of patients observe no changes in therapeutic effect.
However, some patients may experience a change in therapeutic effect and, subsequently, must continue treatment with the brand-name medication. Generic Prozac, fluoxetine, is a selective serotonin reuptake inhibitor SSRI antidepressant which is approved for the treatment of major depressive disorder, obsessive-compulsive disorder OCD , panic disorder and bulimia nervosa.
Frequently reported side effects for generic Prozac are similar those observed in patients being treated with the brand-name medication and may include abnormal dreams, abnormal ejaculation, anorexia, anxiety, asthenia, diarrhea, dry mouth, dyspepsia, flu syndrome, impotence, insomnia, decreased libido, nausea, nervousness, pharyngitis, rash, sinusitis, somnolence, sweating, tremor, vasodilatation and yawn.

Patients should discuss the benefits and risks of Prozac with their health care provider prior to initiation of treatment. What is the difference between Cymbalta versus Prozac? There are a number of differences between Cymbalta duloxetine versus Prozac fluoxetine.
The main differences between Cymbalta versus Prozac include mechanism of action, the way in which the drug works in the body, and indications for use approved by the U.
Cymbalta is a potent inhibitor of both serotonin and norepinephrine reuptake in the central nervous system, while Prozac is a much more potent inhibitor of serotonin reuptake than norepinephrine. The only common indication between Cymbalta and Prozac is major depressive disorder. Cymbalta belongs to a class of antidepressants known as serotonin norepinephrine reuptake inhibitors SNRI and is indicated for the treatment of major depressive disorder, generalized anxiety disorder, diabetic peripheral neuropathic pain, fibromyalgia and chronic musculoskeletal pain.
Prozac belongs to a different class of antidepressants known as selective serotonin reuptake inhibitors SSRI and is indicated for the treatment of major depressive disorder, obsessive-compulsive disorder, panic disorder and bulimia nervosa. Another difference between Cymbalta versus Prozac is approved use in the pediatric population.
While Prozac is currently approved, by the FDA, for the treatment of major depressive disorder and obsessive-compulsive disorder in the pediatric population, both in children and adolescents, the safety and effectiveness of Cymbalta in the pediatric population has not been established. Another difference between Cymbalta versus Prozac is there is currently no generic equivalent available for Cymbalta, while Prozac is available in a generic form, known as fluoxetine.
Cymbalta and Prozac have similar adverse reactions and warnings and precautions associated with treatment. However, Cymbalta has been associated with an increased risk of mydriasis prolonged dilation of the pupils of the eye and should be used cautiously in patients with controlled narrow-angle glaucoma.
Patients should be advised to discuss with their health care provider if they have a past medical history of glaucoma prior to initiation of treatment with Cymbalta. Another difference between Cymbalta versus Prozac, with regard to warnings and precautions, Cymbalta treatment was observed to worsen glycemic control in some patients with diabetes during clinical trials.

When treating a pregnant woman with PROZAC, the physician should carefully consider both the potential risks of taking an SSRI, along with the established benefits of treating depression with an antidepressant.
Animal Data In embryo-fetal development studies in rats and rabbits, there was no evidence of teratogenicity following administration of fluoxetine at doses up to However, because fluoxetine crosses the placenta and because of the possibility that fluoxetine may have adverse effects on the newborn, fluoxetine should be used during labor and delivery only if the potential benefit justifies the potential risk to the fetus.
In one breast-milk sample, the concentration of fluoxetine plus norfluoxetine was No adverse effects on the infant were reported. In another case, an infant nursed by a mother on PROZAC developed crying, sleep disturbance, vomiting, and watery stools. Manic reaction, including mania and hypomania, was reported in 6 1 mania, 5 hypomania out of 2.
As with other SSRIs, decreased weight gain has been observed in association with the use of fluoxetine in children and adolescent patients. After 19 weeks of treatment in a clinical trial, pediatric subjects treated with fluoxetine gained an average of 1. In addition, fluoxetine treatment was associated with a decrease in alkaline phosphatase levels. The safety of fluoxetine treatment for pediatric patients has not been systematically assessed for chronic treatment longer than several months in duration.
In particular, there are no studies that directly evaluate the longer-term effects of fluoxetine on the growth, development and maturation of children and adolescent patients. Therefore, height and weight should be monitored periodically in pediatric patients receiving fluoxetine. Anyone considering the use of PROZAC in a child or adolescent must balance the potential risks with the clinical need.
Animal Data Significant toxicity on muscle tissue, neurobehavior, reproductive organs, and bone development has been observed following exposure of juvenile rats to fluoxetine from weaning through maturity.
When animals were evaluated after a drug-free period up to 11 weeks after cessation of dosing , fluoxetine was associated with neurobehavioral abnormalities decreased reactivity at AUC as low as approximately 0. In addition, the testicular and epididymal microscopic lesions and decreased sperm concentrations found in high dose group were also observed, indicating that the drug effects on reproductive organs are irreversible.
The reversibility of fluoxetine-induced muscle damage was not assessed. These fluoxetine toxicities in juvenile rats have not been observed in adult animals. Rat exposures to the major metabolite, norfluoxetine, are approximately 0. A specific effect on bone development was reported in juvenile mice administered fluoxetine by the intraperitoneal route to 4 week old mice for 4 weeks at doses 0.
There was a decrease in bone mineralization and density at both doses, but the overall growth body weight gain or femur length was not affected. Safety and effectiveness of PROZAC and olanzapine in combination in patients less than 10 years of age have not been established.
The efficacy in geriatric patients has been established [see Clinical Studies ]. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
Hepatic Impairment In subjects with cirrhosis of the liver, the clearances of fluoxetine and its active metabolite, norfluoxetine, were decreased, thus increasing the elimination half-lives of these substances. A lower or less frequent dose of fluoxetine should be used in patients with cirrhosis. Of the cases of overdose involving fluoxetine hydrochloride, alone or with other drugs, reported from this population, there were deaths.
Among adult patients who overdosed on fluoxetine hydrochloride alone, 34 resulted in a fatal outcome, completely recovered, and 15 patients experienced sequelae after overdosage, including abnormal accommodation , abnormal gait , confusion , unresponsiveness, nervousness, pulmonary dysfunction, vertigo , tremor , elevated blood pressure, impotence , movement disorder, and hypomania.
The remaining patients had an unknown outcome. The most common signs and symptoms associated with non-fatal overdosage were seizures, somnolence , nausea, tachycardia , and vomiting. The largest known ingestion of fluoxetine hydrochloride in adult patients was 8 grams in a patient who took fluoxetine alone and who subsequently recovered.
However, in an adult patient who took fluoxetine alone, an ingestion as low as mg has been associated with lethal outcome, but causality has not been established.
Among pediatric patients ages 3 months to 17 years , there were cases of overdose involving fluoxetine alone or in combination with other drugs. Six patients died, patients completely recovered, 1 patient experienced renal failure, and 22 patients had an unknown outcome. He had been receiving mg of fluoxetine daily for 6 months in addition to clonidine, methylphenidate, and promethazine.
Mixed-drug ingestion or other methods of suicide complicated all 6 overdoses in children that resulted in fatalities. The largest ingestion in pediatric patients was 3 grams which was nonlethal.
Other important adverse reactions reported with fluoxetine overdose single or multiple drugs include coma, delirium , ECG abnormalities such as nodal rhythm, QT interval prolongation and ventricular arrhythmias , including Torsades de Pointes-type arrhythmias , hypotension , mania , neuroleptic malignant syndrome-like reactions, pyrexia, stupor, and syncope. Animal Experience Studies in animals do not provide precise or necessarily valid information about the treatment of human overdose. However, animal experiments can provide useful insights into possible treatment strategies.
Acute high oral doses produced hyperirritability and convulsions in several animal species. Tachycardia and an increase in blood pressure were observed. Consequently, the value of the ECG in predicting cardiac toxicity is unknown. Treatment should consist of those general measures employed in the management of overdosage with any drug. Consider the possibility of multi-drug overdose. Ensure an adequate airway, oxygenation , and ventilation. Monitor cardiac rhythm and vital signs.
Use general supportive and symptomatic measures. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose. If you miss a dose of Prozac Weekly, take the missed dose as soon as you remember and take the next dose 7 days later.
