Those products are unapproved drugs that haven't proven their safety or effectiveness, and they contain unapproved chemicals similar to sildenafil, Viagra's active ingredient, according to the FDA.
Those chemicals, which aren't noted on the Blue Steel and Hero product labels, "may dangerously affect a person's blood pressure level," an FDA news release states.
"Because these products are labeled as 'all-natural dietary supplements,' consumers may assume that they are harmless and pose no health risk," says Janet Woodcock, MD, director of the FDA's Center for Drug Evaluation and Research. "But an unsuspecting consumer with underlying medical issues may take these products without knowing that they can cause serious side effects and interact in dangerous ways with drugs that a consumer is already taking."
The undeclared ingredients in these products could interact with nitrates found in some prescription drugs (such as nitroglycerin) and can lower blood pressure to dangerous levels.
People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. ED is a common problem in men with these medical conditions. Because they may have been advised against taking ED drugs, these men may seek products like Blue Steel and Hero because the products are marketed as "all natural" or as not containing the active ingredients in approved ED drugs, the FDA notes.
The FDA advises people who have used either of these products to discontinue use and consult their health care professional if they have experienced any adverse events that they feel are related to the use of these products.
Consumers or health care professionals can report adverse events to the FDA's MedWatch program by phone at 800-FDA-1088 or on the FDA's web site.
The FDA recommends that consumers talk to their health care professional about FDA-approved treatments for erectile dysfunction. The FDA also says it may take further regulatory actions to protect consumers from these illegal products.
Blue Steel is sold in bottles containing 10 blue capsules or blister packs containing two blue capsules. Hero is sold in blister packs containing two blue capsules.
