It has not been approved for
weight loss.
Weight loss is a serious side effect of this
drug, and hence is often being used off label to help people lose weight. Trial using this drug for weight loss had to be discontinued due to side effects which could become serious such as dizziness, ataxia, vomiting, diarrhea, mood disorders, memory loss, difficulty in concentrating, anemia, dyspnea, loss of libido, and bladder problems.
Personally, I would not recommend you to use these pills.
