What is lorcaserin?

Donna Hill Howes, RN
Family Practitioner

Lorcaserin (Belviq) is a weight-loss drug that suppresses appetite by causing a feeling of fullness. The drug probably activates nerve receptors in the hypothalamus, but exactly how it works is not well understood. Lorcaserin is approved for people with a BMI of 30 or more, and for people with a BMI of 27 to 30 with certain conditions, such as diabetes, high blood pressure, or high cholesterol. It should be used along with diet and exercise.
