Health Canada has advised consumers not to use a product called Eden Herbal Formulations Sleep Ease Dietary Supplement, because it was found to contain an undeclared drug estazolam, which can be habit-forming when used for as little as a few months.

Consumers who may still have this product in their homes are advised to consult with a health care professional before they stop taking the capsules, because of the risk of withdrawal symptoms, a Health Canada release stated.

Estazolam belongs in the class of drugs known as benzodiazepines, a class of drugs that should only be prescribed by a healthcare practitioner. Estazolam should not be used by people with an allergy to any benzodiazepines, such as Valium (diazepam), Restoril (temazepam) and Ativan (lorazepam), or those individuals affected by the neuromuscular disorder myasthenia gravis or by sleep apnea. Benzodiazepines, including estazolam, should only be used by pregnant women if absolutely necessary, and with caution by the elderly, and those with a history of substance abuse. The side-effects associated with the use of products containing estazolam vary according to the individual and can include dizziness, drowsiness, confusion, depression, loss of memory and hallucinations.
