FDA laboratory analysis confirmed that Phentamene XT contains undeclared DMAA, also known as 1,3-dimethylamylamine or methylhexanamine. The dietary supplement industry often refers to DMAA as “geranium extract.” Ingestion of DMAA can elevate blood pressure and could lead to cardiovascular problems, including heart attack, shortness of breath and tightening of the chest. Consumers who have experienced any negative side effects should consult a healthcare professional as soon as possible.

Healthcare professionals and consumers 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.
