How Do Antidepressants Work?

Brain neurotransmitters (chemical messengers) serotonin, norepinephrine, and dopamine are changed when stress overload occurs. Antidepressants restore the balance of neurotransmitters. They lower them if too high and raise them if too low. A point to note: SSRI’s only help serotonin levels. Many stress disorders also need norepinephrine/dopamine readjusted for full remission.
