How Prozac (Fluoxetine) Works
Fluoxetine (Prozac) works by inhibiting the reabsorption of serotonin in the brain. Serotonin is a neurotransmitter that helps regulate mood, anxiety, sleep, and overall mental well-being. In individuals with conditions like depression or anxiety, serotonin levels may be imbalanced, contributing to mood disorders.
By blocking the reuptake of serotonin into nerve cells, fluoxetine allows more serotonin to remain available in the synaptic space between neurons. This increased serotonin availability helps improve communication between brain cells and is believed to alleviate symptoms of depression, anxiety, and other mood disorders.
Although the exact mechanism is not entirely understood, it is generally believed that Prozac’s ability to enhance serotonin function significantly impacts mood and behavior. It is important to note that Prozac may take several weeks to show noticeable effects, and patients are usually advised to continue taking the medication as prescribed to allow time for the full benefits to manifest.
