Cymbalta can be stopped, but like any other medication in its class it requires a slow taper. At 60 mg per day, I was told the stopping time would be 11-12 weeks, going down 10 mg per week. But it still works for me, so no problem at this time. Higher doses, as for depression, are much harder to stop, so I am resisting an increase at this,point.

It actually caused me intestinal problems. Constipation being the worst. I’m totally off Cymbalta now but it was sooo hard .

There is a FB page "Cymbalta Hurts Worse" with comments from people who struggle for years to taper off this drug, which often didn't help relieve their symptoms much. It's a private group.
