Male enhancement pill sold nationwide on Amazon is recalled

Certain boxes of The Red Pill — male sexual enhancement capsules sold nationwide on Amazon — are being recalled because they may contain a hidden ingredient: an unapproved drug for treatment of male erectile dysfunction.

Jackson, New Jersey-based Your Favorite Shop announced the recall after being "notified by Amazon that laboratory analysis has found the product to be tainted with tadalafil," according to an announcement posted Tuesday by the U.S. Food and Drug Administration. 

Tadalafil is an ingredient in FDA-approved products for treatment of male erectile dysfunction, and its presence in the Red Pill means the product is an unapproved drug and its safety and efficacy not established, the recall statement said.
