Cymbalta for low back pain

I have been prescribed Cymbalta for my low back pain. It is working but I am gaining weight. Is there anything else I can do?

Cymbalta has been shown to lower pain intensity in patients with fibromylagia and low back pain. Some people do benefit from this drug. The other antidepressants have not been found to work as well. Unfortunately the drug is expensive and does cause significant weight gain. Switching to other antidepressants may not help. I would recommend venlafaxine, which is available as a generic and has been shown to reduce pain in fibromyalgia. In the meantime, eat less and walk more.
