Health Canada warns Canadians about U-Dream herbal sleep-aid products after tests detect a substance similar to a prescription insomnia drug, which may pose serious health risks.

Health Canada is advising Canadians that it has tested several U-Dream Lite and U-Dream Full Night herbal sleep-aid products and has found that they contain a substance similar to the prescription drug zopiclone, which may pose serious health risks. The Department has suspended all of the company’s U-Dream and U-Dreams product licences, which means it is now illegal for any person or company to sell these products in Canada.
