A North Texas coffee maker is recalling products after testing revealed an ingredient similar to the drug Viagra.

Officials with the Food and Drug Administration (FDA) conducted a test of Bestherbs Coffee’s “New of Kopi Jantan Tradisional Herbs Coffee.” The test revealed the presence of desmethyl carbodenafil, a drug similar in structure to the active ingredient sildenafil in the male enhancement drug Viagra, Food Safety News reported.

The food safety website reported:

No illnesses had been confirmed in relation to the Bestherbs Coffee product as of the posting of the recall on July 13. However, in May a recall notice of a similar product by Caverflo.com reported one death. New of Kopi Jantan Tradisional Natural Herbs Coffee also contains milk, which is not declared on the packaging as required by federal law. People who have milk allergies or sensitivities and consume this product, are at risk of serious or life threatening reactions, according to the recall notice posted on the FDA website. The undeclared desmethyl carbodenafil in the coffee could interact with nitrates in other prescription drugs, such as nitroglycerin. It is common for men with diabetes, high blood pressure, high cholesterol or heart disease to be prescribed nitrates. The undeclared drug could lower blood pressure to dangerous levels.

The recall states that no illnesses have been reported to date. The manufacturer is attempting to notify its customers of the voluntary recall.

The affected product can be identified by the UPC barcode number 557205060083, officials stated. It is shipped to consumers in a box of 25 instant coffee packets. The products were sold between July 2014 and June 2016 to customers via the internet.

The FDA advised that consumers can return the product to the company for a refund, including postage. People who discover they have the affected product may contact the company via email, Albertyee.abc@hotmail.com or by calling Bestherbs Natural Coffee at 817-903-2288.
