 September 2019 The U.S. Food and Drug Administration is advising consumers not to purchase or use LOBO, Love in S, Sheaya Lender, and Mero Macho sold and advertised as dietary supplements. FDA has identified an emerging trend in which over-the-counter products, frequently represented as dietary supplements, contain hidden active ingredients that could be harmful. Consumers may unknowingly take products laced with varying quantities of approved prescription drug ingredients, controlled substances, and untested and unstudied pharmaceutically active ingredients. These deceptive products can harm you! LOBO This product promoted for sexual enhancement was identified in an examination of international mail shipments. The red LOBO text and fierce wolf image resemble the mascot of the University of New Mexico, and package copy in Spanish states Maximiza tu potencia sexual – Doble dosis de poder (Maximize your sexual potency – double dose of power). The Food and Drug Administration is advising consumers not to purchase or use LOBO, which contains sildenafil, the active ingredient in the prescription drug Viagra. This undeclared ingredient may interact with nitrates found in some prescription drugs, such as nitroglycerin, and may lower blood pressure to dangerous levels. Mero Macho Mero Macho is sold on the websites fitoterapiausa.com and meromachodrink.com (both sites are currently under construction). FDA laboratory analysis confirmed that Mero Macho contains tadalafil, the active ingredient in the prescription drug Cialis, used to treat erectile dysfunction. Adverse reactions noted in the Cialis prescribing information include headache, indigestion, back pain, myalgia, nasal congestion, flushing, and limb pain. Contraindications are organic nitrates (tadalafil potentiates the hypotensive effect of nitrates), patients with known serious hypersensitivity to tadalafil, and concomitant guanylate cyclase stimulators. People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. Sheaya Lender FDA is advising consumers not to purchase or use Sheaya Lender, a product promoted for weight loss. This product was identified during an examination of international mail shipments. FDA laboratory analysis confirmed that Sheaya Lender contains sibutramine and fluoxetine. Sibutramine is a controlled substance that was removed from the market in October 2010 for safety reasons. This product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or heart rate in some people and may present a significant risk for people with a history of coronary artery disease, congestive heart failure, arrhythmia, or stroke. This product may also interact, in life-threatening ways, with other medications a consumer may be taking. Fluoxetine is an FDA-approved drug in a class of drugs called selective serotonin reuptake inhibitors (SSRIs) used for treating depression, bulimia, obsessive-compulsive disorder, panic disorder, and premenstrual dysphoric disorder. The use of SSRIs has been associated with serious side effects including suicidal thinking, abnormal bleeding, and seizures. Ventricular arrhythmia or sudden death can occur when patients are also taking other medications for common conditions (aspirin, ibuprofen, or other drugs for depression, anxiety, bipolar illness, blood clots, chemotherapy, heart conditions, and psychosis). Love in S FDA is advising consumers not to purchase or use Love in S, a product promoted and sold for weight loss. The package has the torso of a fit woman, images of fruits and other plants, and the words “love in S lose inches Natrually.” FDA laboratory analysis confirmed that Love in S contains sibutramine and N-desmethylsibutramine. N-desmethylsibutramine is structurally similar to sibutramine (as described above, sibutramine is a controlled substance that has been removed from the market). “These products are masquerading as dietary supplements — they may look like dietary supplements but they are not legal dietary supplements,” says Michael Levy, director of FDA’s Division of New Drugs and Labeling Compliance. “Some of these products contain hidden prescription ingredients at levels much higher than those found in an approved drug product and are dangerous.” FDA has received numerous reports of harm associated with the use of these products, including stroke, liver injury, kidney failure, heart palpitations, and death. Dietary Supplements and the FDA Dietary supplements, in general, are not FDA-approved. Under the Dietary Supplement Health and Education Act of 1994, dietary supplement firms do not need FDA approval prior to marketing their products. It is the company’s responsibility to make sure its products are safe and that any claims are true. Just because you see a supplement product on a store shelf does NOT mean it is safe or effective. When safety issues are suspected, FDA must investigate and, when warranted, take steps to have the product removed from the market. However, it is much easier for a firm to get a product on the market than it is for FDA to take a product off the market. FDA has worked with the supplement industry to recall numerous products with potentially harmful ingredients including products marketed for weight loss, products marketed for sexual enhancement, and products marketed for body building. The agency has issued warning letters, seized products, and conducted criminal prosecutions. In December 2010, a woman pleaded guilty to an 18-count indictment charging her with the illegal importation and distribution of more than four million diet pills that contained a controlled substance, unapproved drugs, and a possible cancer-causing agent. These hidden ingredients pose a risk to consumer health. Remember, FDA cannot test all products marketed as dietary supplements to identify those containing potentially harmful hidden ingredients. Consumers must be aware of these dangerous products and learn how to identify and avoid them using the warning signs described below. Advice for Consumers What can you do? Be an informed consumer. Know the source of the dietary supplements you buy. Read the label information. Subscribe to FDA notifications informing the public of products marketed as dietary supplements or conventional foods with hidden drug ingredients and chemicals. These products are typically promoted for sexual enhancement, weight loss, and body building and are often represented as being “all natural.” Consumers should exercise caution before purchasing any product in the above categories. “We need consumers to be aware of these dangerous products and to learn how to identify and avoid them,” says Levy. Consumers should look for potential warning signs of tainted products marketed as dietary supplements, such as products claiming to be alternatives to FDA-approved drugs or to have effects similar to prescription drugs, products claiming to be a legal alternative to anabolic steroids, products marketed primarily in a foreign language, products with typographical errors in the label information, or products marketed through mass emails. Beware of sexual enhancement products promising rapid effects, such as working in minutes to hours, or long-lasting effects, such as working for 24 to 72 hours. Generally, if you are using or considering using any product marketed as a dietary supplement, FDA suggests that you check with your healthcare professional or a registered dietician about any nutrients you may need in addition to your regular diet. Ask your healthcare professional for help distinguishing between reliable and questionable information. Ask yourself if it sounds too good to be true. Be cautious if the claims for the product seem exaggerated or unrealistic. Watch out for extreme claims — “quick and effective,” “cure-all,” “can treat or cure diseases,” or “totally safe.” Be skeptical about anecdotal information from personal “testimonials” about incredible benefits or results obtained from using a product.
