Health Canada has seized a Viagra-like drug that was being sold illegally in Valleyfield.
It's warning purchasers that the product contains prescription medication that could be dangerous.
Officials seized a shipment of 'Stiff Rock' pills at the border, and then determined it had also been sold at Boutique Erotique 5ieme Ave. in Valleyfield.
The product contains sildenafil, the active ingredient in Viagra, and two chemicals of a similar nature.
The drugs involved have a number of side effects including low blood pressure, chest pain, headaches and hearing loss.
People who have purchased or used 'Stiff Rock' should contact their doctors and Health Canada.
