FDA warns consumers of counterfeit ExtenZe

SILVER SPRING, Md. — The Food and Drug Administration on Friday warned consumers about a counterfeit product represented as "ExtenZe," which is the name of an authentic dietary supplement for male sexual enhancement.

The counterfeit product looks similar to the actual product, but either contains tadalafil, or a combination of tadalafil and sildenafil, all active ingredients in FDA-approved prescription medicines for erectile dysfunction.

"This incident is an example of a growing trend of products marketed as dietary supplements or conventional foods with hidden drugs and chemicals," said Ilisa Bernstein, deputy director of the Office of Compliance in the FDA's Center for Drug Evaluation and Research. "These types of products are typically promoted for sexual enhancement, weight loss, and body building, and are often represented as being 'all natural.' Consumers should exercise caution before purchasing products promoted for these uses."

The counterfeit product has the following lot numbers on the packages: LOT 1110075 and LOT F050899.

“Consumers who have an ExtenZe product should check the lot numbers on the package to make sure they do not have a counterfeit product,” the FDA said. “Consumers who think they might have the counterfeit product should stop taking the product and contact their healthcare professional if they are experiencing any negative side effects.”
