The FDA has begun posting on its Web site a list of drugs that are under investigation for safety problems. It includes some drugs with problems already widely reported, such as anaphylactic-type reactions associated with heparin and cancers that may be linked to tumor necrosis factor blocker use in children and young adults. Insulin and nitroglycerin are on the list because confusing labeling may contribute to dosage errors or inaccuracies. The list will be updated quarterly.


Based on reports from the FDA's Adverse Event Reporting System (AERS), the list doesn't indicate how serious or widespread the safety concerns are. An FDA spokeswoman says it will help inform the public and healthcare professionals about potential safety issues but isn't intended to alarm consumers. If your patient is worried about a drug on the list, tell him to discuss his concerns with his healthcare provider. He shouldn't stop taking the drug unless directed to do so by his provider.
