Description

Prozac 20mg capsules are a prescription medication used to treat various mental health conditions, including:

• Major depressive disorder (MDD) in adults 
• Obsessive-compulsive disorder (OCD) in adults 
• Bulimia nervosa in adults, used alongside psychotherapy to reduce binge-eating and purging 
• Moderate to severe major depressive disorder in children and adolescents aged 8 years and above, when depression does not respond to psychological therapy alone 

The recommended starting dose for adults is 20mg per day, which can be gradually increased up to a maximum of 60mg per day if needed. For elderly patients or those with liver impairment, a lower starting dose of 20mg every other day may be prescribed. Prozac works by increasing levels of the neurotransmitter serotonin in the brain, which can help improve mood and reduce symptoms of the conditions it is used to treat. Common side effects of Prozac include nausea, headache, insomnia, and drowsiness. More serious side effects like serotonin syndrome, bleeding, and changes in heart rhythm are also possible. Patients should be monitored closely, especially when starting or stopping treatment. Prozac should be stored at room temperature, away from heat and light. Unused medication should be disposed of properly to prevent accidental ingestion or environmental contamination.

Key IngredientThe active ingredient in Prozac 20mg capsules is:

• Fluoxetine – a selective serotonin reuptake inhibitor (SSRI) antidepressant

Fluoxetine works by blocking the reuptake of the neurotransmitter serotonin in the brain, leading to increased serotonin levels and improved mood and symptoms of the conditions Prozac is used to treat.  Mechanism of Action of Fluoxetine (Prozac)Fluoxetine, the active ingredient in Prozac, is a selective serotonin reuptake inhibitor (SSRI) antidepressant. Its mechanism of action is primarily attributed to its ability to block the reuptake of the neurotransmitter serotonin (5-HT) in the presynaptic terminal of certain brain areas.By inhibiting the serotonin reuptake transporter, fluoxetine leads to sustained and increased levels of serotonin in the synaptic cleft. This ultimately results in enhanced serotonergic neurotransmission in specific brain regions associated with the regulation of mood, anxiety, and other functions affected in conditions like depression, OCD, and bulimia nervosa.Fluoxetine binds with relatively poor affinity to other receptors like 5-HT, dopaminergic, adrenergic, cholinergic, muscarinic, and histamine receptors. This selective action on the serotonin system contributes to the favorable adverse effect profile of fluoxetine compared to earlier antidepressant classes like tricyclic antidepressants.The exact mechanisms by which increased serotonin levels lead to the therapeutic effects in depression, OCD, and bulimia nervosa are not fully understood. However, the monoaminergic hypothesis suggests that dysfunction of neurotransmitters like serotonin is linked to the pathophysiology of these disorders                                                                                                                The chemical structure of fluoxetine, the active ingredient in Prozac 20mg capsules, is:

Fluoxetine hydrochloride has a molecular weight of 345.79 and the structural formula:

It is a white to off-white crystalline solid with a solubility of 14 mg/mL in water

Reviews

Fluoxetine is generally well-tolerated, with common side effects including nausea, headache, insomnia, and drowsiness. More serious side effects like serotonin syndrome, bleeding, and changes in heart rhythm are also possible. Patients should be monitored closely, especially when starting or stopping treatment.
