I take a generic version of Prilo Sec and it works quite well, however the packaging says you're only supposed to use it for a couple weeks, but once your system gets adjusted to it, if you stop taking it, your AR will come back even stronger than before, so as far as I can tell, once you start it, you're taking it for life.
I've also heard it can cause bone fragility over the long term, but I've used it for years now with no sign of that. Also, it takes 24 hours to get into your system and take effect, so you can't forget your daily dose, or you're likely to have a nasty flare-up.
