Duloxetine and Fluoxetine are both medications used to treat various mental health conditions. While they belong to the same class of drugs known as selective serotonin reuptake inhibitors (SSRIs), there are some key differences between the two.

Duloxetine, also known by the brand name Cymbalta, is primarily used to treat depression, anxiety, and nerve pain. It works by increasing the levels of serotonin and norepinephrine in the brain, helping to regulate mood and relieve pain.

Fluoxetine, often sold under the brand name Prozac, is mainly prescribed for depression, obsessive-compulsive disorder (OCD), and bulimia. It works by increasing the levels of serotonin in the brain, which can improve mood and reduce symptoms of depression and anxiety.

It is important to consult with a healthcare professional to determine which medication is best suited for your individual needs and medical history.
