Arize: Public Notification - Undeclared Drug Ingredient

Audience: Consumer

[Posted 08/11/2014]

ISSUE: FDA is advising consumers not to purchase or use Arize, a product promoted and sold for sexual enhancement. FDA laboratory analysis confirmed that Arize contains sulfoaildenafil. Sulfoaildenafil is structurally similar to sildenafil, the active ingredient in Viagra, an FDA approved prescription drug for erectile dysfunction (ED). This undeclared ingredient 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.

BACKGROUND: Arize is promoted and sold for sexual enhancement on various websites and in some retail stores.

RECOMMENDATION: Do not purchase or use Arize. Consumers who have experienced any negative side effects should consult a health care professional as soon as possible.
