Health Canada has completed a safety review of human health products and veterinary drugs containing gentian violet and has found that exposure to these products may increase the risk of cancer. Given the seriousness of this risk, Health Canada is advising Canadians to stop using all human and veterinary drug products containing gentian violet.

 

Gentian violet is an antiseptic dye used to treat fungal infections. Products containing gentian violet have been used on the skin, on mucous membranes (inside the nose, mouth or vagina), on open wounds, or on the nipple of a nursing mother to treat oral thrush in infants.

 

Health Canada’s review was triggered by the World Health Organization’s Codex Alimentarius Commission’s recommendation on the potential risk of cancer associated with veterinary drug residues in foods, including gentian violet. Although the Commission’s recommendations were specific to food residues, Health Canada reviewed the safety of human non-prescription drugs, veterinary drugs and medical devices containing gentian violet.

 

After completing two safety assessments, the Department concluded that, as with other known cancer causing substances, there is no safe level of these products, and therefore any exposure to these products is a potential cause for concern.

What you should do is to stop using all drug products that contain gentian violet, including on animals. Products for humans should be returned to a pharmacy for proper disposal. Animal owners can discuss options for the safe disposal of their products with their veterinarians or local pharmacies.
