The Food and Drug Administration is conducting a safety review of weight-loss drugs Alli and Xenical and looking at whether the drugs are linked to liver problems.
The FDA, in a quarterly report of drugs that lists potential safety issues the agency is evaluating, also said it was looking at serious skin problems possibly involving the smoking cessation drug Chantix and the over-active bladder drug Detrol. Both drugs are made by Pfizer Inc. (PFE). The most recent quarterly report was posted to the FDA's Web site Thursday.

The FDA said the appearance of a drug on its quarterly report simply means the agency has identified a "potential" safety issue but doesn't mean the drug is the cause of the particular problem.
