Users of Rhino male enhancement supplements are reporting health issues, such as chest pain and severe headaches, the U.S. Food and Drug Administration warned on Tuesday.
The undeclared ingredients in these products are the same as or structurally similar to the active ingredients found in FDA-approved prescription drugs for treating erectile dysfunction such as sildenafil and tadalafil in Viagra and Cialis, the FDA said in its statement. The agency has also been investigating smuggled raw materials used to produce Rhino capsules since 2015.
“Hidden active drug ingredients continue to be identified in products that are misrepresented as dietary supplements and promoted for sexual enhancement, weight loss, bodybuilding and/or pain relief,” the statement said.
The FDA has received reports of chest pain, severe headaches, prolonged erection and hospitalizations due to extreme drops in blood pressure after taking a Rhino product.
“Over the past few years, the FDA has been combating the retail sale of male enhancement drug products that are frequently misrepresented as dietary supplements and that contain hidden and potentially harmful active drug ingredients. Distributing unapproved drugs, disguised as supplements, places the U.S. public health at risk,” Donald D. Ashley, director of the Office of Compliance in the FDA’s Center for Drug Evaluation and Research said in a statement. “We remain vigilant in our efforts to protect the American public from the sale of these potentially dangerous products.”
The agency encourages consumers who have experienced adverse health effect related to a dietary supplement to report it through the FDA’s MedWatch Safety Information program.
