Unlike authorized and authentic drug products, counterfeit drugs have not been assessed by Health Canada for safety, effectiveness, and quality. Selling counterfeit health products is illegal.
Like the authentic versions, the seized products are labelled to contain either the prescription drug sildenafil or tadalafil. Sildenafil and tadalafil should be used only under the supervision of a health care professional. They should not be used by individuals taking any kind of nitrate drug (e.g., nitroglycerin) as they can cause potentially life-threatening low blood pressure.

Individuals with heart problems are at increased risk of cardiovascular side effects such as heart attack, stroke, chest pain, high blood pressure, and abnormal heartbeat. Other possible side effects include headache, facial flushing, indigestion, dizziness, abnormal vision, and hearing loss.
Health Canada reminds consumers that the best way to make sure their prescription drugs are authentic is to buy them from a licensed pharmacy and should be taken only under the advice and supervision of a health care professional. Prescription drugs can only be legally sold to consumers in Canada with a prescription and cannot be sold in convenience stores.
