Fluoxetine

Fluoxetine, commonly known by the brand name Prozac^®, is a selective serotonin reuptake inhibitor (SSRI) primarily used to treat major depressive disorder and anxiety disorders. Another brand-name version of fluoxetine, Sarafem^®, is approved to treat premenstrual dysphoric disorder (PMDD). Fluoxetine works by increasing available serotonin levels in the brain, helping to regulate mood and emotional stability.

For depression and anxiety, the recommended dosage starts at 10 to 20 milligrams (mg) per day, although a healthcare provider may adjust this depending on your symptoms and needs.

Fluoxetine has a longer half-life compared to other SSRIs, which means withdrawal symptoms are less severe but can still occur if the medication is stopped abruptly. Some people may experience increased anxiety or restlessness when starting the medication, which typically resolves with continued use.
