Welcome to the forum! I've never drank cortisicoids - they've always been in pill form for me. How long I take it depends on how long a flare up is...sometimes it's only for 6 days, sometimes it's 3 months, sometimes it's been 6 months. Everyone's different. I think some people here on the forum have been taking steriods for years. It just depends....
Sorry you have to be here, but good luck to you!
