'Power-X' Removed from Sale at BC's Chong Kun Dang Health Store: May Pose Serious Health Risks to Canadians

OTTAWA, ONTARIO--(Marketwire - March 12, 2012) -

The issue:

An unauthorized health product, "Power-X" has been removed from a Canadian retail location after Health Canada's testing identified undeclared thiodimethylsildenafil which is similar to the prescription medication sildenfil. "Power-X" is promoted for increasing sexual performance and desire and may pose serious risks to the health of Canadians.

"Power-X" was being sold at the Chong Kun Dang Health store in Burnaby, British Columbia. It has been removed from store shelves at this location but it is important to note that the product may be sold elsewhere.

Who is affected:

Canadians who have purchased "Power-X", particularly individuals with heart problems, those at risk of stroke or those taking any nitrate drug (e.g. nitroglycerine) are affected. Affected products are packaged in boxes of 20 capsules, in blister packs of 10 capsules, and individual packs of 1 capsule.

Some natural health products (NHPs) may have an Exemption Number (EN), which indicates that the product is legally available for sale while Health Canada is reviewing its application for licensing.

Sildenafil should only be used under the supervision of a health care practitioner. Products containing 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 cardio-vascular side effects if they engage in sexual activity, including if they use sildenafil to help them achieve an erection. Other possible side-effects of using sildenafil include headache, facial flushing, indigestion, dizziness, abnormal vision and hearing loss.

Canadians who have taken unauthorized prescription products without the supervision of a healthcare practitioner or without a prescription may face additional risks. You may be misdiagnosed, the treatment might not be appropriate to treat your illness and you may miss the opportunity to obtain appropriate medical treatment. You may also put yourself at risk for drug interactions, or harmful side effects.
