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.

Cymbalta should not be used in combination with monoamine oxidase inhibitors (MAOI) (for example, phenelzine [Nardil]).At least 5 days should be allowed after stopping Cymbalta before starting an MAOI.he most common side effects of Cymbalta are nausea, dry mouth, constipation, diarrhea, fatigue, drowsiness, difficulty sleeping, loss of appetite, and dizziness. Some patients may experience withdrawal reactions such anxiety, nausea, nervousness, and insomnia.
