Public Notification: MANNERS Energy Boost contains hidden drug ingredient
[2-2-2023] The Food and Drug Administration is advising consumers not to purchase or use MANNERS Energy Boost, a product promoted and sold to boost energy on www.amazon.com and possibly in some retail stores.
FDA laboratory analysis confirmed that MANNERS Energy Boost contains tadalafil, the active ingredient in the FDA-approved prescription drug Cialis, used to treat erectile dysfunction. FDA approval of Cialis is restricted to use under the supervision of a licensed health care professional. This undeclared ingredient 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.
Health care professionals and consumers should report adverse events or side effects related to the use of these products to FDA's MedWatch Safety Information and Adverse Event Reporting Program:
- Complete and submit the report online at MedWatch Online Voluntary Reporting Form, or;
- Download and complete the form, then submit it via fax at 1-800-FDA-0178.
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, or 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.
