Consumer Alert: Revivexxx Extra Strength and Solo Slim

Both have undeclared ingredients, which were discovered by the FDA.

Both pose a risk to people who use them and are being withdrawn from the marketplace.

Revivexxx Extra Strength

  • Contains tadalafil (Cialis), which is an FDA-approved drug to treat male erectile dysfunction.
  • It poses a threat to consumers because tadalafil may interact with nitrates found in some prescription drugs such as nitroglycerin and may lower blood pressure to dangerous levels.
  • People with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates.

Solo Slim and Solo Slim Extra Strength

  • Contain the undeclared ingredient didesmethyl sibutramine, which is a derivative of the FDA-approved appetite suppressant sibutramine (Meridia).
  • These products pose a threat to consumers because sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients.
  • It may present a significant risk for people with a history of coronary artery disease, congestive heart failure, arrhythmias or stroke.

The bottom line?

Return these products to the place of purchase for a full refund and contact your doctor if you experience any problems that may be related to taking these products.
