Health Canada is warning consumers not to use Firm Dose and Granite Rooster, two products promoted to enhance male sexual performance, as they contain potentially harmful unlisted ingredients.

Firm Dose contains an undeclared pharmaceutical ingredient similar to the prescription drug sildenafil, while Granite Rooster contains an undeclared pharmaceutical ingredient similar to the prescription drug tadalafil, Health Canada said Thursday.

Patients with heart problems who take these drugs may be at increased risk of sudden cardiac death, heart attack, stroke, low blood pressure, chest pain and abnormal heartbeat.

Consumers are being advised to return the products to the place of purchase.
