Announcement

Health Canada warns Canadians of potential cancer risk associated with non-prescription gentian violet drug products

Health Canada conducted 2 health risk assessments on gentian violet-containing products and the risk of cancer. One focused on a non-prescription drug product (Gentiane Violet Liquid Topical) and the other on medical devices (Hydrofera antibacterial foam dressings). Health Canada's assessment of the non-prescription drug product concluded that there is a risk of cancer, due to oral exposure. The assessment of the medical devices containing gentian violet did not find this risk.

Health Canada's risk assessment of the non-prescription drug product concluded that there is evidence in the scientific literature, based on animal studies, that there is a potential for gentian violet to cause cancer. There was only one non-prescription drug product containing gentian violet marketed in Canada, Gentiane Violet Liquid Topical. The manufacturer voluntarily discontinued the sale of the product in Canada in May 2019, and the product licence has been cancelled.

Health Canada's risk assessment of licensed medical devices containing gentian violet (Hydrofera antibacterial foam dressings), based on the limited exposure to gentian violet, did not find a risk of cancer. However, no evidence to support the safety of the devices for pregnant and nursing women was provided to Health Canada by the manufacturer. As a precaution, Health Canada worked with the manufacturer to strengthen the device safety information to better inform users.

Summary Safety Review
Information Update

Monthly recap of health product safety information

The following is a list of health product advisories, type I recalls, as well as summaries of completed safety reviews published in May 2019 by Health Canada.

Actemra (tocilizumab)

Serious drug-induced liver injury, in some cases resulting in acute liver failure requiring a transplant, has been reported in patients treated with Actemra. Healthcare professionals are advised not to recommend Actemra in patients with active hepatic disease or hepatic impairment, and refer to the approved Canadian product monograph for guidance on the recommended dose adjustments (reduction, interruption or discontinuation) in patients with liver enzyme elevations. Patients are advised to contact a healthcare professional if they experience signs of liver injury. Health Canada is working with the manufacturer to include this new safety information in the Canadian product monograph.

Health Professional Risk Communication - Actemra (tocilizumab)

Alaris Infusion Sets

Becton Dickinson (BD) has recalled additional lots of the Alaris Pump Infusion Sets due to a manufacturing defect that can cause unintended delivery which can result in over-infusion. The April 28, 2019 list of affected products has been expanded to include all model codes and lot numbers with an expiration date between 05/2019 and 08/2020. BD has also confirmed that the affected lots were distributed beginning in August 2018, and not November 2018, as previously indicated.

Update - Health Professional Risk Communication - Alaris Infusion Sets

Biocell breast implants

Health Canada's safety review evaluated the risk of breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). This safety review found that there was an increased risk of BIA-ALCL with the use of highly textured (macro-textured) implants, in comparison with those having less textured or smooth implants. Biocell breast implants made by Allergan are the only macro-textured implants currently available in Canada. Health Canada has suspended the licences held by Allergan for their Biocell textured breast implants. Health Canada will work with all breast implant manufacturers to strengthen the Instructions for Use of all breast implants regarding the risk of BIA-ALCL. Health Canada has also communicated this information to Canadians.

Summary Safety Review - Biocell breast implants

Cellex Photopheresis System

This safety review evaluated the risk of venous thromboembolism and pulmonary embolism associated with Cellex Photopheresis System (CPS). Health Canada's review concluded that the majority of thromboembolic events occurred after the use of CPS for treatment of graft versus host disease (GvHD), which is not an intended use of CPS. Health Canada has requested the manufacturer of CPS to update the Instructions for Use to include a warning that treatment of patients with GvHD is not an authorized use in Canada.

Summary Safety Review - Cellex Photopheresis System

Extraneal peritoneal dialysis solution

Two lots of Extraneal peritoneal dialysis solution were recalled as a precautionary measure because of high levels of sodium hydroxide. Use of the affected product in patients could cause chemical peritonitis. The lots affected by this recall were distributed by Baxter between March 14, 2019 and March 20, 2019. Further to the original communication, Baxter Corporation has issued an update indicating that one of the recalled lots (Extraneal 2L/2L Twinbag, product code JB9912, lot number W9B28T0), may have also been distributed on March 21, 2019, in addition to March 14 to 20, 2019.

Update - Extraneal peritoneal dialysis solution

Foreign health products

These foreign health products have been found by regulators in the United States, Singapore and Australia to contain undeclared drug ingredients, which may pose serious health risks. These products are not authorized for sale in Canada and have not been found in the Canadian marketplace, but it is possible they may have been brought into the country by travellers or purchased over the Internet.

Foreign Product Alert

Health products manufactured by Konsar Future Nutrition Inc.

All products manufactured by Konsar Future Nutrition Inc. may pose serious health risks. Health Canada inspected the manufacturing site (located in Dollard-des-Ormeaux, Quebec) and found serious unsanitary conditions and quality control issues. As a result, Health Canada has suspended the company's site licence and all 101 of its product licences.

Paclitaxel-coated balloons and paclitaxel-eluting stents

A meta-analysis published in the Journal of the American Heart Association has identified a possible increased risk of death after the use of paclitaxel-coated balloons (PCB) and paclitaxel-eluting stents (PES) to treat peripheral arterial disease (PAD). Healthcare professionals are advised to continue surveillance of patients who have been treated for PAD with PCB and PES according to current standards of care, determine whether the benefits of using these devices outweigh the risks, and follow the additional recommendations provided in the communication. Health Canada has also requested that manufacturers update the labelling of paclitaxel-containing devices to include details about this potential risk.

Unauthorized cell therapy treatments

Health Canada advised Canadians that some clinics and healthcare professionals are offering unauthorized cell therapies, such as stem cell therapy, suggesting that these treatments are safe, and are making unproven health claims to patients. Unauthorized treatments have not been proven to be safe, or effective, and may cause life-threatening or life-altering risks, such as serious infections. Health Canada published a position paper to clarify the regulatory status of these products.

Information Update - Unauthorized cell therapy treatments

Unauthorized health products

Health Canada advised Canadians about various unauthorized health products being sold at retail locations across Canada or online that may pose serious health risks.
