For what it's worth, store-brand fluticasone tends to be a lot cheaper than Flonase and is exactly the same stuff. Most people have fewer side effects with Flonase/fluticasone than with Nasacort/triamcinolone. Either way, plan on taking it extremely long-term, though -- as in, for several months nonstop. It's safe to do that since we're not talking about "normal" nasal sprays (e.g., Afrin) that you can't take for more than a day or two at a time, but the anti-inflammatory effects start to wear off about a day or two after you lapse. And it suuuuucks, at least if you have chronic sinus issues.
