Health Canada advised consumers not to use Optimum Health Care SleePlus TCM or BYL SleePlus, saying the products contain the undeclared drug clonazepam, which can be habit-forming when used for a few months.

Consumers are advised to consult with a healthcare professional before they stop taking the pills because of the risk of withdrawal symptoms, said Health Canada.

Optimum Health Care SleePlus TCM and BYL SleePlus have different names but are the same formulation, and both products are promoted as a sleep aid, the agency said. The products are not authorized for sale in Canada.

The side-effects associated with the use of products containing clonazepam vary according to the individual and can include dizziness, drowsiness, confusion, depression, loss of memory and hallucinations, Health Canada said.
