What Are the Side Effects of Slimming Coffee?

Slimming coffee contains the substance sibutramine. Sibutramine may increase blood pressure and pulse rate, and may be a risk for those with a history of coronary artery disease, congestive heart failure, arrhythmias or stroke, says the FDA.

Slimming coffee, also known as Leisure 18 slimming coffee, is a beverage designed to help individuals conveniently shed excess weight, reports the FDA. The product is sold on a variety of websites and in some stores. Additional side effects of ingesting slimming coffee may be headache, constipation, heartburn, dry mouth, weakness and back pain. More serious side effects include seizures, fainting, shivering and abnormal movement, claims MedlinePlus.

The ingredient responsible for the weight loss is sibutramine, which was unlisted on the product ingredient label, says Drug Office. Sibutramine is an oral anorexiant, or appetite suppressant. It is typically prescribed to help individuals lose and then maintain their weight. It works by affecting the part of the brain that controls appetite, reports MedlinePlus. By decreasing appetite, sibutramine curbs the eating habits of its users. Sibutramine may also interact with other medications a consumer may be taking, which could be potentially life threatening, claims the FDA.

Sibutramine was removed from U.S. markets in October, 2010 for safety reasons, reports the FDA. The FDA also advises consumers to immediately halt use of the product and throw the rest away. They also advise consumers who continue to use slimming coffee to exercise caution.
