OTTAWA (CP) - Consumers are being warned not to use Zencore Tabs - a product advertised as a dietary over the counter erectile dysfunction medication for sexual enhancement, Health Canada said Saturday.

The federal health watchdog says it’s because it contains an undeclared tadalafil guenstig
similar to tadalafil, used for the treatment of erectile dysfunction.

Health Canada says the use of Zencore Tabs could pose serious health risks, especially for those with existing heart problems or those at risk of stroke. The agency says tadalafil combined with any nitrate medication could result in potentially life-threatening low blood pressure.

Zencore Tabs is not authorized for sale in Canada and Health Canada says the Canadian importer is recalling the product. Consumers who’ve bought them are warned not to use it and to consult with a medical professional.

Health Canada says it’s taking steps to confirm the product has been removed from the Canadian market, and there have been no reports of adverse reactions.

Zencore Tabs is sold in blister packages of two pink-purple capsules, and was available at retail outlets and possibly over the Internet.
