From MSNBC:
Hundreds of reports of suicides, psychotic reactions and other serious problems tied to the popular stop-smoking drug Chantix were left out of a crucial government safety review because Pfizer Inc., the drug’s manufacturer, submitted years of data through “improper channels.”
Some 150 suicides — more than doubling those previously known — were among 589 delayed reports of severe issues turned up in a new analysis by the non-profit Institute for Safe Medication Practices.
“We’ve had a major breakdown in safety surveillance,” said Thomas J. Moore, the ISMP senior scientist who analyzed the data. The serious problems — including reports of completed suicides, suicide attempts, aggression and hostility and depression — had been mixed among some 26,000 records of non-serious side effects such as nausea and rashes, with some dating back to 2006, the year Chantix, or varenicline, was approved.
