Can Cymbalta cause confusion?

I agree with the previous responder. Its a known factor one of the most common side effect, of this medication, in elderly people is: confusion, problems concentrating and thinking or memory problems. Let your mom's physician know, might have to decrease the dosage.

Hi amk27. I was prescribed Cymbalta for nerve pain and ended up with anxiety, depression, confusion, suicidal thoughts, dizziness, exhaustion, brain fog, memory loss, blurry vision, emotional blunting, muscle and joint pain, along with many other side effects. I was in so much pain I was misdiagnosed with fibromyalgia. I’m in a Cymbalta support group where there are over 30,000 people having trouble with this medication and they are getting help tapering off it. They helped me taper off Cymbalta and now that I’m completely off it every side effect is gone.

Confusional state is considered an uncommon side effect which affects 0.1% to 1.0% of people being treated with this medication.

I suggest you inform her Dr., perhaps she needs a dose adjustment.
