FDA Warns Consumers Not to Use Weight Loss Supplement

On November 9, 2016, the FDA warned consumers not to buy or use the weight loss supplement Supreme Slim 5.7 because it was found to contain sildenafil and phenolphthalein.

Sildenafil, the active ingredient in Viagra and tadalafil, the active ingredient in Cialis, are drugs prescribed for erectile dysfunction. Desmethyl carbodenafil is similar to sildenafil. These drugs can cause symptoms like headache and flushing, and can interact with medications containing nitrates such as nitroglycerine, resulting in dangerously low blood pressure.

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."  Supreme Slim 5.7 was sold on various Web sites, including www.absolutenaturalweightloss.net, and possibly in some retail stores.

Consumers who have purchased this supplement should discontinue use immediately and contact their healthcare provider if they have experienced any adverse side effects. Consumers and healthcare providers are also encouraged to report any adverse reactions to the FDA's MedWatch Adverse Event Reporting Program.
