FDA warns Americans about dietary supplements

The U.S. Food and Drug Administration on Friday warned consumers against taking certain dietary supplements containing a prescription drug ingredient that could cause a sharp loss in blood pressure.

The FDA said consumers should not purchase or consume SIGRA, STAMINA Rx and STAMINA Rx for Women, Y-Y, Spontane ES or Uroprin manufactured by NVE Inc., in Newton, New Jersey and distributed by Hi-Tech in Norcross, Georgia.

The agency said the products contain the prescription-strength ingredient, tadalafil, the active ingredient in Cialis, a product of Eli Lilly and Co. that is approved in Europe to treat male erectile dysfunction. An interaction between certain prescription drugs containing nitrates (such as nitroglycerin) and tadalafil may cause a drastic lowering of blood pressure.

The agency's Office of Criminal Investigations executed federal search warrants in Georgia and New Jersey after finding the dietary supplements. Spokesmen for NVE Inc. and Hi-Tech could not be reached for comment.
