The U.S. FDA released an updated public health alert regarding counterfeit Alli being sold over the internet.

According to the FDA, here’s what you need to know:

  • Alli is an FDA-approved, over-the-counter weight loss drug.
  • FDA lab tests have confirmed that counterfeit versions of the drug do not contain the FDA-approved active ingredient; rather, they are made with varying amounts of the stimulant sibutramine.
  • Sibutramine can be particularly harmful to those who have a history of cardiovascular disease and can lead to elevated blood pressure, stroke or heart attack.
  • The counterfeit drugs have been identified as Alli 60mg capsules (120 count refill pack)

If you take Alli, it’s important that you check it for:

  • Missing lot numbers on the outer cardboard packaging;
  • An expiration date that includes a month, day and year—expiration dates on legitimate packages include the month and year only;
  • A wordless inner safety seal—the real product contains the words “SEALED FOR YOUR PROTECTION” on its inner seal;
  • Large capsules containing white powder instead of the small white pellets; and
  • A taller bottle with a wider, coarser cap than real Alli packaging

If you think you’re in possession of counterfeit Alli, you’re asked to contact the FDA’s Office of Criminal Investigations (OCI) at 800-551-3989 or via their Web site.
