What % of people taking qsymia (phentermine and topiramate) lost >15 pounds in the first 3 months? what was the overall average pounds lost by each person on the qsymia (phentermine and topiramate) study?

Complicated answer: There were 3 trials involving Qsymia (phentermine and topiramate) and depending on how the authors analyzed the data, the degree of weight loss was different. In the equip study, one analysis showed a 5% weight loss at 52 weeks on the lower dose of qsymia (phentermine and topiramate). But this was in severely obese people (bmi>35) so the effects may not be applicable to lower bmi people. Talk with your doc about risks/benefits, and if right for you.
