Magic Slim: Public Notification - Undeclared Drug Ingredient

Audience: Consumer

[Posted 01/22/2014]

ISSUE: FDA is advising consumers not to purchase or use Magic Slim, a product promoted and sold for weight loss and sold on various websites and in some retail stores. FDA laboratory analysis confirmed that Magic Slim contains sibutramine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. The product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. These products may also interact, in life-threatening ways, with other medications a consumer may be taking.
Laboratory analysis also confirmed that Magic Slim contains phenolphthalein. Phenolphthalein was an ingredient in some over-the-counter (OTC) laxative products until 1999, when FDA reclassified the ingredient as “not generally recognized as safe and effective” after studies indicated that it presented a potential cancer-causing (carcinogenic) risk.

BACKGROUND: Magic Slim is a product promoted and sold for weight loss and sold on various websites, including, and in some retail stores. See the FDA Public Notificiation for additional information, including a product photo.
