Three lots of a dietary supplement called RockHard Weekend are being recalled today because they contain an ingredient used in erectile dysfunction products that is not listed on the labeling, the Food and Drug Administration said. FDA laboratory testing determined that some RockHard Weekend packages contain sulfoaildenfil, which is related to Sildenfil, the active ingredient in FDA-approved erectile dysfunction drugs.
The undeclared use of the drug ingredient in the recalled supplements may pose a risk of death or injury to users who take nitrates and prescription medications, such as nitroglycerin, for high blood pressure, heart disease, diabetes, and other conditions, the FDA said.
Negative interaction between sulfoaildenfil and nitrates could result in life-threatening drops in blood pressure, officials said. RockHard Laboratories said one of the raw ingredients imported from China was tainted with sulfoaildenfil, causing the product contamination.
