Food and Drug Administration officials have issued a consumer alert on the safety of dietary supplements containing ephedra that calls for consumers to immediately stop buying and using ephedra products. Besides issuing the alert, FDA officials have notified manufacturers that they intend to publish a final rule stating dietary supplements containing ephedrine alkaloids present an unreasonable risk of illness or injury. The rule would have the effect of banning the sale of these products as soon as it becomes effective, 60 days after publication. Military service officials have in turn issued warnings about using ephedra.
