Health Canada 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.
Health Canada tested the products after receiving complaints of unusual side effects—such as symptoms of withdrawal and dependence—suggesting that the products may contain a substance not listed on the product label.
Zopiclone is used to treat insomnia. Side effects include drowsiness, dizziness, memory loss, hallucinations and abnormal sleep behaviours while not fully awake including sleep driving (which can result in serious injuries). Zopicline use may lead to dependence or abuse, and stopping the drug abruptly may cause withdrawal symptoms, including convulsions, tremor, muscle cramps, vomiting, sweating, hallucinations and difficulty sleeping.
In addition, zopiclone should not be used by pregnant or nursing women, children, or patients with breathing difficulties.
Health Canada has asked Biotrade Canada Ltd., which sells U-Dream Lite and U-Dream Full Night in Canada, to recall the products and will take further action as needed.
