From the link.

"The bottles contain the "presence" of nitrosamine drug substance impurity, N-nitroso-duloxetine, that exceeds the recommended interim limit, according to the FDA."

"The FDA states that nitrosamine impurities "may increase the risk of cancer if people are exposed to them above acceptable levels and over long periods of time." However, it clarifies, "a person taking a drug that contains nitrosamines at-or-below the acceptable daily intake limits every day for 70 years is not expected to have an increased risk of cancer."

I think you have nothing to worry about. You should check with your pharmacy about future availability of Cymbalta. I think only Eli Lilly can sell duloxetine under the brand name Cymbalta unless they license the rights to someone else. Frequently the difference between Cymbalta and other formulations is the additives other than the active ingredient. IIRC Cymbalta offered by others would need to be the same formulation, but generics are supposed to be equally effective. Unfortunately you are stuck with whatever version your pharmacy chooses to purchase so it would be difficult to try that from a new supplier each month. Every lot of every drug that is imported is supposed to be tested but some slip through. I understand that Walmart does their own testing.
