Is the valve disease reversible?
A. It is not known at this time. One report has been submitted to FDA in which the valve disease appeared to improve. However, we encourage those people who have taken fenfluramine or dexfenfluramine to contact their physician and discuss the appropriate follow-up, even after stopping their medicine. The full medical implications of these findings are not known at this time, especially as they relate to the asymptomatic valvular changes. The FDA and other government agencies, the manufacturers, and medical researchers will aggressively follow this concern and keep patients and health care providers informed of what is learned about the natural history of the valvular disease caused by these medications.
