Sibutramine, the active ingredient in the obesity drug Meridia, was removed from the U.S. market in October 2010 because it can substantially increase blood pressure and pulse rate in some individuals, and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias, or stroke. This drug may also interact, in life-threatening ways, with other medications a consumer may be taking.

Phenolphthalein, once an ingredient in some over-the-counter laxative products, was reclassified by the FDA in 1999 as "not generally recognized as safe and effective."

Slim Max is promoted for weight loss various websites and possibly in some retail stores.
