How PRISTIQ works

Depression is a serious medical condition that can hold you back from what you enjoy. And while no one knows for certain what causes it, experts believe that depression results when certain chemicals in the brain are out of balance. These chemicals, called neurotransmitters, relay messages from one brain cell to another.

PRISTIQ is in a class of medications known as SNRIs, or serotonin-norepinephrine reuptake inhibitors. Serotonin and norepinephrine are chemicals that relay messages from one brain cell to another.

PRISTIQ is thought to work by affecting the levels of these two brain chemicals, both thought to play a role in depression.

Many people shy away from antidepressants due to side effects. It can take time to find the right medication for you.

You and your doctor can determine if the benefits of treatment outweigh the burden of side effects. Always discuss any side effects you are experiencing with your doctor.
