[10-3-2017] The Food and Drug Administration (FDA) is advising consumers not to purchase or use A1 Slim, a product promoted and sold for weight loss on various websites, including www.Amazon.com, and possibly in some retail stores.
FDA laboratory analysis confirmed that A1 Slim contains sibutramine and phenolphthalein.
Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. This product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or heart 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. This product may also interact, in life-threatening ways, with other medications a consumer may be taking.
Phenolphthalein is a chemical that is not an active ingredient in any approved drug in the United States. Studies indicate that it may increase the risk of cancer
Health care professionals and patients are encouraged to report adverse events or side effects related to the use of this product to FDA’s MedWatch Safety Information and Adverse Event Reporting Program:
Note: This notification is to inform the public of a growing trend of dietary supplements or conventional foods with hidden drugs and chemicals. These products are typically promoted for sexual enhancement, weight loss, and body building and are often represented as being “all natural.” FDA is unable to test and identify all products marketed as dietary supplements that have potentially harmful hidden ingredients. Consumers should exercise caution before purchasing any product in the above categories.
