Public Notification: Slim Bio Capsules contain hidden drug ingredients

[1-28-2019] The Food and Drug Administration is advising consumers not to purchase or use Slim Bio Capsules, a product promoted for weight loss. This product was identified during an examination of international mail shipments.

Slim Bio Capsules

FDA laboratory analysis confirmed that Slim Bio Capsules contain sibutramine, N-desmethylsibutramine, sildenafil, tadalafil, benproperine and diphenhydramine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. N-desmethylsibutramine is a substance structurally similar to sibutramine. Sibutramine is known to substantially increase blood pressure and/or heart rate in some people and may present a significant risk for people 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.

Sildenafil and tadalafil are the active ingredients in the FDA-approved prescription drugs Viagra and Cialis, respectively, used to treat erectile dysfunction. These undeclared ingredients may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower blood pressure to dangerous levels. People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.

Benproperine is an active ingredient not approved by FDA, and therefore its safety and efficacy have not been established.Diphenhydramine is an over-the-counter antihistamine used for seasonal allergy treatment. Antihistamines may cause drowsiness and affect mental alertness.

Health care professionals and patients should 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 products marketed as dietary supplements or conventional foods with hidden drug ingredients 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.
