In brief: Well......

The half-life of Cymbalta (duloxetine) is about 12 hours.
It takes about 5 half-lives for medication to essentially be cleared from your system. However, since some people metabolize the medication more slowly it would be safe to assume the medication would be gone from your system within five days.
