On November 16, 2007, American True Man Health Incorporated announced that it is expanding it's voluntary recall of the Company's dietary supplement product sold under the name and identified as True Man's Sexual Energy Nutriment Men's Formula with the expiration date up to and including December 2010 to also include the dietary supplement product sold under the name and identified as Energy Max, Energy Supplement Men's Formula (the products) with the expiration date up to and including December 2010. Finished products from several lots of these products were tested and were found to contain an analog of an ingredient in an FDA-approved drug. The analog resembles the active pharmaceutical ingredients in Tadalafil, Vardenafil, and Sildenefil, FDA-approved drugs used to treat erectile dysfunction (ED). Consequently, the products may possess a similar pharmacological and adverse event profile, posing a threat to consumers because of interaction with nitrates found in some prescription drugs (such as nitroglycerin) and may lower blood pressure to dangerous levels. Consumers with diabetes, high cholesterol, or heart disease often take nitrates. ED is a common problem in men with these conditions, who may seek products to enhance sexual performance. Additionally, the product may cause side effects, such as headaches and flushing.
