Federal drug safety officials are warning consumers about counterfeit sex-enhancement pills that are sold as supplements but contain the drugs used in Viagra and another medication.
The Food and Drug Administration said Friday that the fake "ExtenZe" pills, marketed to improve male sexual performance, contain tadalafil and sildenafil, the active ingredients in Cialis and Viagra. Both drugs require a doctor's prescription.
The FDA says the counterfeit product looks like ExtenZe, which is an herbal supplement. It says the counterfeit products are marked with lot numbers 1110075 and F050899.
The FDA says consumers should stop taking any questionable pills and contact their doctors about any side effects.
An FDA official says there is a growing trend of products that are marketed as supplements but contain hidden drugs and chemicals.
