Reason for Warning
The U.S. Food and Drug Administration (FDA) warned consumers not to use these weight loss products after they were found to contain undeclared drug ingredients as follows:
Japan Weight Loss Blue: found to contain sibutramine, unauthorized substances similar to sibutramine, and ephedrine alkaloids.
Japan Rapid Weight Loss Diet Pills Green: found to contain sibutramine and phenolphthalein.
Japan Rapid Weight Loss Diet Pills Yellow: found to contain phenolphthalein.
Sibutramine was previously used to treat obesity but is no longer authorized for sale in Canada because of its association with an increased risk of cardiovascular side effects such as heart attack and stroke. Unauthorized substances that are similar to sibutramine may pose similar health risks.
Ephedrine alkaloids are compounds derived from the plant Ephedra (Ma Huang). Ephedrine may also be chemically synthesized. Ephedrine is authorized for the relief of nasal congestion but is not authorized for sale in Canada as a stimulant or weight loss product.
Phenolphthalein was previously used as a laxative but is no longer authorized for sale in Canada because it may cause cancer.
According to the U.S. FDA alerts, these products are sold on various websites.
Possible Side-Effects
In addition to heart attack and stroke, side-effects associated with sibutramine include increased blood pressure and heart rate, dry mouth, difficulty sleeping and constipation.
Side-effects associated with ephedrine include fast or abnormal heartbeat, chest pain, high blood pressure, dizziness, insomnia, and facial flushing.
Additional side-effects associated with phenolphthalein include decreased blood pressure, skin rash and gastrointestinal bleeding.
