Meridia (sibutramine) was a prescription medication previously used to support weight loss in adults with obesity. It worked by affecting certain brain chemicals involved in appetite regulation, helping reduce hunger and food intake. Meridia was intended to be used alongside a reduced-calorie diet and lifestyle changes to support weight management. However, it was withdrawn from the U.S. market in 2010 because studies found an increased risk of serious cardiovascular events, including heart attack and stroke. Meridia is not an approved weight-loss treatment in the United States. Anyone seeking effective weight-management solutions should consult a qualified healthcare professional about currently approved medications, healthy eating habits, and appropriate physical activity. Always verify product safety and avoid unapproved weight-loss medicines.
