ISSUE: X-Rock Industries LLC is conducting a recall of certain supplement products under the brand name of X-ROCK. Analytical tests of X-ROCK for Men conducted by FDA concluded that the products contained Sildenafil and Hydroxythiohomosildenafil. Hydroxythiohomosildenafil is an analogue of sildenafil. Sildenafil is the active pharmaceutical ingredient in an FDA-approved drug that is used to treat erectile dysfunction (ED). Hydroxythiohomosildenafil is close in structure to sildenafil and is expected to possess a similar pharmacological and adverse event profile.
These undeclared active ingredients pose a threat to consumers because sildenafil and hydroxythiohomosildenafil may interact with nitrates found in some prescription drugs (such as nitroglycerin) and lower blood pressure to dangerous levels. Consumers with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. ED is a common problem in men with these conditions, and they may seek products to enhance sexual performance. Additionally, hydroxythiohomosildenafil, like sildenafil, may cause side effects, such as headaches and flushing.
BACKGROUND: XRock for Men was distributed Nationwide to wholesalers and retail to the consumer via internet orders. XRock for Men was distributed in single blister cards.
