If you take duloxetine — the generic form of the antidepressant Cymbalta — check the lot number on your bottle right now.
Breckenridge Pharmaceutical, Inc. has voluntarily recalled multiple lots of duloxetine delayed-release capsules after laboratory testing found levels of a chemical called N-nitroso-duloxetine above the FDA's acceptable daily intake limit. N-nitroso-duloxetine is a nitrosamine compound — a class of substances classified as probable human carcinogens, meaning that repeated long-term exposure above safe levels may increase cancer risk over time.
