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.
