If you have sinusitis, then you may need antibiotics as well as steroids. The steroids actually help the antibiotics to work better at clearing up the infection.

As for the steroid dose for SFN, there are taper packs that start at 60 mg for 2-3 days, then 40 mg for a couple days, then 30, 20, 10, 5 etc until you taper off. This is a moderate to hefty dose, but IF it was going to help, you should notice it with this dose. They also taper packs that start lower at 40 mg or higher at 80 mg...and then they taper down from there just like the first one mentioned.
