How Cymbalta Is Believed to Work

Cymbalta offers relief from symptoms of depression, generalized anxiety disorder (GAD), diabetic nerve pain (DNP), and fibromyalgia. Cymbalta is not a narcotic.

Although the exact way that Cymbalta works in people is unknown, it is believed to be related to an increase in the activity of serotonin and norepinephrine, which are two naturally occurring substances in the brain and spinal cord. Cymbalta is in a class of medications called selective SNRIs (serotonin and norepinephrine reuptake inhibitors).

What should I talk about with my healthcare provider?

Call your healthcare provider right away if you have thoughts of suicide or if any of these symptoms are severe or occur suddenly.
