Health Canada is warning consumers not to use Zencore Tabs because the dietary supplement for sexual enhancement contains an undeclared pharmaceutical ingredient similar to the drug tadalafil.

Tadalafil, a prescription drug for erectile dysfunction, should only be used under the supervision of a health professional. Zencore Tabs could pose serious health risks, especially for patients with heart problems, on heart medication or at risk of stroke.

Products containing tadalafil should not be used by anyone taking nitrate medication because combining these products could result in the development of potentially life-threatening low blood pressure.

Zencore Tabs are not authorized for sale in Canada, and the Canadian importer has been contacted and is recalling the product. The product was available at retail outlets and may also have been sold over the internet.

Zencore Tabs are sold in blister packages of two pink-purple capsules. There have been no reports of adverse reactions.

For more information about this warning, contact Health Canada's public enquiries line at (613) 957-2991 or toll free at 1-866-225-0709.
