Today the government posted its first quarterly online list of medications under investigation for potential problems.
The first list from the FDA names 20 medications and the potential safety issue for each.
But it provides no indication of how widespread or serious the problems might be.
Drugs will be placed on the list based on reports the FDA receives regularly from hospitals, doctors and patients.
The FDA is also hoping the list with generate more reports from medical providers.
