Unauthorized NorthRegentRx Product: ResurreXX Being Recalled From the Canadian Market

OTTAWA, ONTARIO--(Marketwire - Dec. 13, 2010) -

The issue:

Health Canada is informing Canadians that NorthRegentRx has begun to voluntarily recall its product, ResurreXX from the Canadian market. NorthRegentRx is requesting that wholesalers, distributors and retailers stop sale of this product.

ResurreXX, promoted as a dietary supplement, was tested by Health Canada and found to contain an undeclared substance "hydroxyhomosildenafil", which is similar to the prescription medication sildenafil, and may pose potentially serious health risks to consumers. Prescription medications should only be taken under the supervision of healthcare practitioners.

Who is affected:

Canadians who have purchased or used "ResureXX", particularly people with heart problems, those at risk of stroke, or those taking any nitrate drug (e.g. nitroglycerine).

What consumers should do:

  • Consult your healthcare practitioner if you have used this product and are concerned about your health.

  • Read the label of the products you buy to verify that they have been assessed by Health Canada for safety, effectiveness and quality. Health products that have been authorized for sale by Health Canada will have an eight-digit Drug Identification Number (DIN), a Homeopathic Medicine Number (DIN-HM) or a Natural Product Number (NPN) on the label. 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.

  • Report any adverse reaction potentially related to these products to Health Canada (see below).

What Health Canada is doing:

Health Canada will monitor the voluntary recall by NorthRegentRx.


Sildenafil is a prescription medication used to treat erectile dysfunction and should only be taken under the supervision of a healthcare practitioner. As outlined in the Canadian prescribing information for products containing sildenafil, sildenafil should never be used by individuals taking any kind of nitrate drug (e.g. nitroglycerine) as this combination could 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 heart beat. Other side-effects include headache, facial flushing, indigestion, dizziness, abnormal vision, and hearing loss.
