In brief: Varies

Diarrhea can be caused by a GI side effect of the drug itself, in which case it will go away when you quit taking it.
On the other hand, diarrhea can occur from disruption of the normal intestinal bacteria flora and that may persist until a balance is restored. If you have persistent diarrhea you should see a doctor to make sure you don't have something more serious (c. Difficile).

In brief: DEPENDS

Gi side effect will last only very short time.
Secondary infection like c.Diff can last long time until treated with appropriate antibiotics.
