My husband was put on Cymbalta for chronic pain back, hands, arthritis, 70 years old. When VA filled script gave him Effexor as generic substitute. He is Vietnam Nam Vet with 13 months of exposure daily to Agent Orange. Right now he has explosive outburst, extremely irritable, will not sit any where in piblic unless back against a wall. This has gotten progressively worse over the years but now it is to the point of being intolerable. Using the Effexor has worsened the outburst and irritability. Should the Effexor be stopped?
