[Posted 10/10/13]

AUDIENCE: Consumer, Health Professional

ISSUE: FDA is advising consumers not to purchase or use Dr. Mao Slimming Capsules. FDA laboratory analysis confirmed that Dr. Mao Slimming Capsules contain sibutramine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons.

This product can also interact in life-threatening ways with other medications a consumer may be taking.

BACKGROUND: Dr. Mao Slimming Capsules is a product promoted for weight loss and sold on various websites and in some retail stores.
