Guys who are using Duro Extend Capsules for Men are being advised by the Food and Drug Administration to dump the drug because of its potentially dangerous side effects.
Why? According to the agency, Duro Extend Capsules — marketed as a “dietary supplement” as well as a “male enhancer” — contain an undeclared drug ingredient which could lower your blood pressure to dangerous levels.
From the FDA safety alert: “Lab analysis has found Duro Extend Capsules for Men to contain Sulfoaidenafil, an analogue of Sildenafil, an FDA-approved drug used as treatment for male Erectile Dysfunction, making the product an unapproved drug. The analogue may interact with nitrates found in some prescription drugs (such as nitroglycerin) and may lower blood pressure to dangerous levels. Consumers with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.”
