Caverflo.com is voluntarily recalling all lots of Caverflo Natural Herbal Coffee, 25 g, to the consumer level. FDA laboratory analysis confirmed the presence of sildenafil and tadalafil, the active ingredients in two FDA-approved prescription drugs used to treat erectile dysfunction (ED). Caverflo.com has received a report of an individual death after use of the coffee. The product may also contain undeclared milk.

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. People who have an allergy or severe sensitivity to milk run the risk of a serious or life-threatening allergic reaction if they consume this product.
