Do SSRIs permanently change your brain?
Selective serotonin reuptake inhibitors (SSRI) such as Prozac are regularly used to treat severe anxiety and depression. They work by immediately increasing the amount of serotonin in the brain and by causing long term changes in brain function.
Why are SSRIs better than tricyclics?
Differences in the Side Effects
