Lorcaserin IR (twice daily) improves smoking cessation rates and prevents post-cessation weight gain in overweight or obese smokers compared to placebo.

If you smoke and are overweight, lorcaserin (10 mg twice daily) can help you quit smoking and prevent the weight gain that often follows. It works by reducing cravings and managing weight. This use is not FDA-approved, so discuss risks and benefits with your doctor.
