Zencore Tabs Recalled for Undeclared ED Drugs

September 2007

Zencore Tabs, a male enhancement dietary supplement, have been recalled due to hazardous ingredients. The Food and Drug Administration found that some Zencore Tabs contain undeclared prescription drugs used to treat Erectile Dysfunction (ED). That means Zencore Tabs carry the same potential risks as their ED prescription counterparts, only without the important package warnings.

It was revealed that one lot of Zencore Tabs contained a variant of tadalafil, the active ingredient in the ED drug Cialis. Notable side effects may include back pain, muscle aches, and other adverse symptoms. Also, the FDA discovered Cialis could lead to vision impairment in certain patients, especially in diabetics.

Another lot of Zencore Tabs was found to contain a variant of sildenafil, the active ingredient in prescription ED drugs such as Viagra and Revatio. Serious side effects of this drug include heart attack, priapism, stroke, and vision impairment. HIV patients are also at an enhanced risk for side effects when sildenafil is combined with Protease inhibitors.

Both sildenafil and tadalafil may react with nitrates, popular ingredients in drugs that treat blood pressure, cholesterol, diabetes, and heart disease. Combining these ED drugs with nitrates could result in a drastic drop in blood pressure to dangerously low levels.
