One common cause of hyperprolactinemia is a growth or tumor on the pituitary gland called a prolactinoma. The tumor produces high levels of prolactin. These tumors can be large or small and are usually benign, meaning they are not cancerous. Large tumors can also cause headaches, vision problems, or both.
The most common symptoms of atypical antidepressant withdrawal, including Cymbalta, are anxiety and low mood, such as apathy and rebound depression. Because Cymbalta strongly affects serotonin, after discontinuation it can take several days for the body's own serotonin system to return to normal.
The efficacy of Cymbalta was established in three short-term and one maintenance trial in adults. Cymbalta is indicated for the management of diabetic peripheral neuropathic pain and fibromyalgia. Antidepressants can increase suicidal thoughts and behaviors in children, teens, and young adults. Suicide is a known risk of depression and some other psychiatric disorders.
