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.
Users of Cymbalta have suffered serious â sometimes fatal â side effects, including liver damage, abnormal bleeding, and suicidal thoughts and behaviors. Whatâs more, stopping use of Cymbalta may lead to a separate set of debilitating side effects such as electric shock sensations, known as brain zaps.
