X-Rock for Men

September 11, 2012

FDA tests found that X-Rock, marketed as a dietary supplement for men, contains the active ingredient sildenafil found in an FDA-approved prescription drug product used to treat erectile dysfunction.

X-Rock for Men, sold in one-capsule blister cards, was distributed nationwide to wholesalers and to consumers through the Internet.

Risk: The active ingredient sildenafil may interact with prescription drugs containing nitrates (such as nitroglycerin) and cause dangerously low blood pressure. People with diabetes, high blood pressure, high cholesterol or heart disease are often prescribed drugs containing nitrates. Another similar active ingredient found in X-Rock may also interact with nitrates and cause side effects, such as headaches and flushing.
