XERISTAR (CYMBALTA) INDICATIONS
Xeristar is used for treating depression and generalized anxiety disorder. It is used for managing pain caused by fibromyalgia and diabetic peripheral neuropathy (DPNP). Xeristar is a serotonin and norepinephrine reuptake inhibitor (SNRI). It works by restoring the balance of certain natural substances in the brain (serotonin and norepinephrine), which helps to improve certain mood problems.
