Canada: "Stiff Rock" male sexual performance enhancement product seized from retail location in Valleyfield, QC
Health Canada is warning consumers that an unauthorized drug, “Stiff Rock” promoted for male sexual performance enhancement was seized from Boutique Érotique 5ieme avenue (also known as Boutique Érotique Liberté), 507 Gande-Île., Valleyfield, QC after Health Canada testing confirmed that the product contained drug ingredients: sildenafil; aminotadalafil; and hydroxythiohomosildenafil. The affected product is available in one tablet per blisterpack, LOT: 100237, EXP: 2016-04-01.

Products containing sildenafil should only be used under the supervision of a healthcare practitioner. Sildenafil should never be used by individuals taking any kind of nitrate drug (e.g. nitroglycerine) as it can cause potentially life-threatening low blood pressure. Individuals with heart problems including high blood pressure, a history of heart attack, stroke, abnormal heart beat or chest pain, are at higher risk of cardiovascular side effects. Other possible side effects of using sildenafil include headache, facial flushing, indigestion, dizziness, abnormal vision and hearing loss.

Hydroxythiohomosildenafil is a substance similar to sildenafil, and may pose similar health risks.

Aminotadalafil is a substance similar to tadalafil, a prescription drug used to treat erectile dysfunction and may pose similar health risks.
