Anyone can read the FDA database on adverse events. Anyone can add to it, patients, caregivers, doctors, etc. Anyone can list whatever drug they think caused the adverse event.
That is why sometimes you see drugs listed without the dose size, or different drugs listed for the same event ( reported by different reporters)
The FDA may or may not investigate the adverse event reported, and if the do and they have a finding, they will list the drug they find responsible.
This is a fairly new search engine developed by TheBusyAnt.com:

This is the official FDA AERS site:
http://www.fda.gov/cder/aers/default.htm
Just remember that this database lists ALL reported events, regardless of who posted the adverse event and take that with a grain of salt.
Hope this helps everyone! Knowledge is power.
