Health Canada is warning consumers not to use RevolutionDS Weight Loss, an unauthorized health product promoted for weight loss, because it contains benzylpiperazine (BZP), and may pose serious health risks.

Currently, BZP has no known therapeutic use. While BZP is frequently claimed to be a natural substance, it is a synthetic substance. It may cause effects such as increased body temperature, increased blood pressure, dilated pupils, increased euphoria, alertness and paranoia. Health Canada is currently assessing whether BZP should be added to one of the schedules to the Controlled Drugs and Substances Act (CDSA). Such a decision would mean that all activities with BZP, such as possession, importation, exportation, distribution, production, etc., would be illegal unless authorized by regulation.

The recommended doses on the labels of the products (1 – 2 capsules) and recommended maximum daily dose on the labels of the products (4 capsules) will expose consumers to levels of BZP that have been associated with serious and life-threatening health consequences, including a Canadian report of cardiac arrhythmia (abnormal electrical activity of the heart) that was reported associated with the use of RevolutionDS Weight Loss. BZP could also negatively interact with other substances, such as alcohol and prescription drugs. Scientific data also indicates that BZP has abuse potential because of its amphetamine-like effects.
