FDA Issues Additional Alerts on Supplements
The U.S. Food and Drug Administration (FDA) has issued several new announcements regarding sexual enhancement supplements. The most recent FDA postings warn consumers and healthcare professionals about the following supplements and the undeclared drug ingredients they include:
Sildenafil is the active ingredient in the FDA-approved prescription drug Viagra, and tadalafil is found in Cialis. Viagra and Cialis are used to treat erectile dysfunction (ED). These undeclared ingredients may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower blood pressure to dangerous levels. Men with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.
The AUA urges its members to alert patients about the harms of these supplements. Patients should be advised to discard unused supplements and to contact the FDA if they experience adverse events or side effects.
Over the last several months, the FDA has posted other alerts, which were reported recently in the Health Policy Brief. Check the April 2April 17, and May 22 editions for more information on the previous alerts.
