OTTAWA – Health Canada is advising consumers that it seized multiple unauthorized products from Vikings Nutrition in Montreal, Quebec (5712, rue Jean-Talon Est), because they are labelled to contain a prescription drug and may pose serious health risks. The products are promoted for sexual enhancement, weight loss, and as a sleep aid.

Selling unauthorized health products in Canada is illegal. Health products that have not been authorized by Health Canada have not been assessed for safety, effectiveness and quality, and may pose serious health risks. For example, unauthorized health products may be contaminated, contain dangerous ingredients not listed on the label, or not contain the ingredient shown on the label.

Prescription drugs must be sold under a prescription, under the advice and supervision of a health care professional, because they are used to treat specific conditions and may cause serious side effects.

It should be used only under the supervision of a health care professional. Levodopa may interact with drugs prescribed for high blood pressure, and should not be used by women who are pregnant, who plan to become pregnant or who are breastfeeding. It should also not be taken by people with narrow angle glaucoma; untreated heart, liver, kidney, lung or hormonal diseases; a history of melanoma; or those who should not take drugs such as isoproterenol, amphetamines or epinephrine.
