Is it bad for a teen to take weight loss pills even if it was prescribed?

Depends: all meds have risks. stimulants for weight loss are generally safe but the patient should have a medical workup w/ EKG. most MDs prefer a young person change their diet and activity level first but for severe obesity, meds may help w/ motivation & decrease food craving. belviq (lorcaserin) is a non stimulant option but not been tested in children. weight loss meds are time limited and not long term solutions.
