Date of alert: April 30, 2008
Source of Alert: Hong Kong Department of Health
Product Name: Tian Sheng Yi Bao
Manufacturer / Place of Origin: Unknown manufacturer / China

Product Description
Tian Sheng Yi Bao is marketed as a proprietary Chinese medicine (photo not available).

Reason for Warning
The Hong Kong Department of Health advised the public not to use the product Tian Sheng Yi Bao because it was found to contain two pharmaceutical products, glibenclamide and phenformin, which are not meant for self-care and could be associated with serious side-effects.

Glibenclamide is used in the treatment of diabetes and should only be used under the supervision of a health care professional. Phenformin is an unauthorized drug that was banned in Canada in 1977 due to its association with fatal lactic acidosis.

Possible Side-Effects
Glibenclamide (trade name Glyburide) is a prescription medication authorized for the management of high blood sugar in certain diabetic patients. Severe low blood sugar is a side-effect that can present as flushing, paleness, chills, trembling, headache, dizziness and confusion. Other side-effects such as nausea, vomiting, heartburn, and abdominal pain may occur. Glibenclamide is not recommended for patients with unstable diabetes and/or those taking insulin, or for patients with severe liver, thyroid or kidney problems.

Phenformin was previously authorized for use in Canada as a prescription medication for the treatment of Type 2 diabetes. However, phenformin was removed from the Canadian market in 1977 due to international reports of life-threatening lactic acidosis. Phenformin has also been banned in several other countries, including Hong Kong, Singapore, Germany, France, and the U.S.
