Health Canada Advises Not To Use Certain Weight Loss Pills
Health Canada is advising consumers not to use Natural (Xin Yi Dai) and Lasmi due to concerns about possible side-effects.
Natural (Xin Yi Dai) and Lasmi are both promoted for weight loss.
Reason for Warning
The Hong Kong Department of Health warned against the use of Natural (Xin Yi Dai) and Lasmi because they were both found to contain undeclared pharmaceutical ingredients.
Natural (Xin Yi Dai) was found to contain sibutramine and phenolphthalein, and Lasmi was found to contain sibutramine and spironolactone.
Sibutramine is used in the treatment of obesity and spironolactone is used in the treatment of fluid retention. Both are prescription drugs that should only be used under the supervision of a health care professional.
Phenolphthalein was previously used in over-the-counter laxative preparations but is currently prohibited in Canada as it may cause cancer. Individuals who may have been exposed to phenolphthalein should consult with their health care professional.
Use of sibutramine may cause headaches, increased heart rate and blood pressure, chest pain and stroke.
Abuse of phenolphthalein-containing laxatives has been associated with stomach and intestinal bleeding, anemia, acute pancreatitis and, in cases of massive overdose, multiple organ damage (including liver failure).
Side-effects associated with spironolactone include electrolyte imbalance, breast enlargement in males, gastrointestinal irritation, fatigue, dizziness and reproductive disorders.
