Phentermine has the active ingredient - panbesy; and Reductil - sibutramine. Even if they are chemically different, they both work in the brain by blocking some receptors and therefore suppressing our appetite.
Some women get fine with Reductil and others with Phentermine, it depends on everyone's body, there's no rule.
I think you'll get good results with Reductil 15 as well.
