Reductil (sibutramine) is, as SG!!!!!!!! says, no longer available through official channels in the UK because the evidence suggested that it wasn't safe.
Most folk who took it when it was prescribable either didn't find it at all effective or struggled to tolerate the appetite suppression. It's fairly predictable that people who are overweight because they enjoy their food aren't going to like the reality of taking a pill that makes them go off eating, however much the idea appeals in theory.
Orlistat is the only slimming pill still available on NHS prescription. At a pinch, it might provide a marginal benefit over diet alone in some people.
If you hang out in the wrong places, you can of course get all sorts of gubbins, from Tenuate Dospan to home-brewed Aicar. But it's not worth it.
