The antidepressant drug duloxetine, known commercially as Cymbalta, helped relieve painful tingling feelings caused by chemotherapy in 59 percent of patients, a new study finds. This is the first clinical trial to find an effective treatment for this pain. Chemotherapy-induced peripheral neuropathy is a common side effect of certain chemotherapy drugs. The tingling feeling -- usually felt in the toes, feet, fingers and hands -- can be uncomfortable for many patients, but for about 30 percent of patients, it’s a painful sensation. Previous studies have found no reliable way to treat this type of pain.
