Fluoxetine and duloxetine are both medication used to treat a variety of conditions, but they work in different ways and are prescribed for different purposes.

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly known by the brand name Prozac. It is primarily used to treat depression, anxiety, and obsessive-compulsive disorder.

Duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI) known by the brand name Cymbalta. It is used to treat depression, anxiety, diabetic peripheral neuropathy, fibromyalgia, and chronic musculoskeletal pain.

While both medications can be effective in managing certain conditions, it is important to consult with a healthcare provider to determine the best treatment option for your specific needs.

Overview of fluoxetine and duloxetine

Fluoxetine and duloxetine are both commonly used medications in the class of selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), respectively. While both medications work by increasing the levels of serotonin in the brain, they differ in their mechanisms of action.

Fluoxetine: is a commonly prescribed SSRI that primarily works by blocking the reuptake of serotonin, thereby increasing its levels in the brain. It is used to treat various mental health conditions such as depression, anxiety, and obsessive-compulsive disorder.

Duloxetine: is an SNRI that works by blocking the reuptake of both serotonin and norepinephrine. This dual mechanism of action allows duloxetine to be used not only for mental health conditions like depression and anxiety but also for conditions like neuropathic pain and fibromyalgia.
