Who can take Belviq?
The FDA approved the medication for people who are obese (with a body mass index, or BMI, of 30 or higher) or who are overweight (with a BMI of 27 or above) and also have at least one weight-related health condition such as Type 2 diabetes, high blood pressure or high cholesterol.
How does Belviq work?
The drug works by controlling appetite – specifically by activating brain receptors for serotonin, a neurotransmitter that triggers feelings of satiety and satisfaction. Serotonin is also involved in mood; many antidepressant drugs work by preventing the reuptake of serotonin and keeping brain receptors bathed in the chemical. Researchers at Arena say their drug is designed to seek out only the serotonin receptors that affect appetite.
Are there any side effects?
The most common side effects of Belviq in non-diabetic patients are headache, dizziness, fatigue, nausea, dry mouth and constipation; in patients with diabetes, side effects include low blood sugar, headache, back pain, cough and fatigue.
The drug’s manufacturer will be required to conduct six postmarketing studies, including a long-term cardiovascular outcomes trial to assess the effect of Belviq on the risk for major adverse cardiac events such as heart attack and stroke.
