CHICAGO-Serious and fatal drug reactions tripled between 1998 and 2005, according to a 2007 FDA analysis. In that time period, the total number of serious adverse drug events multiplied 4 times faster than the number of prescriptions written. The number of serious drug reactions for biotechnology agents rose nearly 18-fold (T Moore et al: Analysis of FDA reported post marketing ADR database, Arch Intern Med 167:1752-1759, 2007).
