Used primarily in the treatment of major depressive disorder, it helps restore the balance of serotonin in the brain, improving mood, sleep, appetite, and energy levels. It is also prescribed for anxiety, panic attacks, and obsessive-compulsive behaviors in some cases. As a selective serotonin reuptake inhibitor (SSRI), it is favored for its relatively low side effect profile compared to older antidepressants. Commonly taken orally in tablet or liquid form, effects typically become noticeable after several weeks of consistent use.
