As I come across them, I will post them here.
Unfortunately, many physicians do not read or understand some of the
new warnings that come out. Some never see them even. So I will post
links here in this post on those that are significant.
This is the main link from FDA:
http://www.fda.gov/cder/warn/warn2004.htm

This is a link to the search engine that you can use to search for your
specific drug, if you think a warning letter has been issued:
http://www.fda.gov/foi/warning.htm
There is some pretty interesting reading at the above site..if you choose
by date, you can see many issues the FDA oversees besides drugs.

1) Cymbalta:

2) Topamax: There are several warnings included in this link:

3) Zoloft:

4) Enbrel:

5) Celebrex and Bextra:
http://www.fda.gov/cder/warn/2005/12560-letter.pdf
and http://www.fda.gov/medWatch/SAFETY/2...ty05.htm#NSAID

6) Paxil + pregnancy:
http://www.fda.gov/MedWatch/SAFETY/2...hcp_letter.pdf
specifically the first trimester when the heart is forming. Discuss Paxil use with your doctor in this event.

These are just some examples. The site is huge.. and includes food and devices, and manufacturing issues/safety.
