Fluoxetine

Description

Fluoxetine is an antidepressant that belongs to a class of medicines called Sel

ective Serotonin Reuptake Inhibitors (SSRIs). It is used to help improve mood, reduce anxiety, and manage several mental health conditions, including depression, anxiety disorder, obsessive-compulsive disorder (OCD), phobias, post-traumatic stress disorder (PTSD), and panic disorder. By balancing brain chemicals, Fluoxetine can help you feel more in control of your thoughts and emotions. Fluoxetine works by increasing serotonin levels, a natural chemical in the brain that affects mood, sleep, and emotions. When serotonin levels are balanced, feelings of sadness, panic, or obsessive thoughts are reduced, and overall mental well-being improves. It may take a few weeks of consistent use to notice the full benefits. Take Fluoxetine exactly as prescribed by your doctor. Do not change your dose or stop taking it without consulting your doctor, even if you feel better.
