Not a good idea. An infection with S. pyogenes is what precipitates rheumatic fever. Steroids do not eliminate the bacterial infection. The chances of a person getting rheumatic fever following a strept. throat infection is about 3%. However, the chances of a person like Sally getting rheumatic fever again following a strept. throat infection is about 65%. Recurrances also carry with them a higher chance of causing permanent damage to the heart. Prevention of future infections is a very important part of managing these patients. If I were you I would try again.
