An open letter to Health Canada

The life-saving, Nobel Prize winning anti-parasitic drug ivermectin is no longer available in Canada for human use. Health Canada, why are you withholding a drug that is on the World Health Organization’s list of essential medicines, and that has the potential to truly help MS sufferers?


1. In 2014, pathologist Dr. Alan MacDonald discovered the presence of nematodes in the brain and spinal fluid of every single deceased MS patient he tested. You can review his research here:

2. Canada has the highest rate of multiple sclerosis worldwide.

3. The incidence of multiple sclerosis in Canada is nearly double in rural prairie provinces compared to larger, more populated cities. Review University of Calgary’s study:

4. The rural areas of Canada have a much higher population of domestic animals.

5. When parasitic nematodes infect the central nervous system of domestic animals, they experience symptoms identical to the symptoms of multiple sclerosis, such as lesions in the central nervous system, loss of myelin, numbness, paralysis, spastic gait, loss of balance, blindness, muscle weakness, bladder issues, difficulty swallowing, etc.

6. Doctors are now beginning to test their MS patients for the presence of these nematodes and feel that their patients would greatly benefit from drugs like ivermectin, praziquantel, pyrantal pamoate, and others.

7. According to The Globe and Mail, Health Canada has restricted the use of ivermectin in Canada. You can read the article here:

8. Ivermectin was available in Canada but is now considered a Special Access Drug. I asked a Health Canada agent why this is, and if there are any warnings or concerns about the drug that would make it a Special Access Drug. Their response was that it is not available in Canada because the drug manufacturer is not making it available in Canada.

9. Because ivermectin is now a Special Access Drug, Canadian doctors who wish to prescribe ivermectin must send a request to Health Canada’s Special Access Programme (SAP). Health Canada then decides on a case-by-case basis if a patient should receive special permission for a prescription of ivermectin. If authorized, a copy of the authorization is sent to the drug manufacturer (Merck & Co. in this case) and to the prescribing doctor. The doctor then must contact the manufacturer for shipping and cost details. This process is costly, time-consuming, and complicated.

10. Some patients are declined the prescription for ivermectin and are forced to seek treatment elsewhere, like this example:

11. Immune suppressing, disease modifying drugs are readily available in Canada. Some of the newer MS drugs cost thousands of dollars each month, whereas a safe, cost-effective drug like ivermectin, which has the potential to greatly improve the quality of life of an MS sufferer, is not available in Canada. According to The Globe and Mail it is not financially feasible for the drug companies to offer this drug in the Canadian market – MS drugs are many times more profitable.

Health Canada, please make safe, effective anti-parasitic drugs available in Canada – and don’t let people suffer over profit.
