High doses (40-120 mg) taken for long periods of time require very slow tapering. Many of us have been on pred for years. One luper I know has been on it for almost 30 years and can't get off. Short. low dose treatments are usually not a problem at all.
The problems come when the dose is high because it shuts down your adrenal glands which produce 7-10mg of cortisol daily. Pred is synthetic cortisol and we cannot survive without it. Long term use of high doses of pred causes adrenal atrophy and the adrenals fail to produce cortisol when pred doses drop below 10 mg or so.
You should be fine but short course treatments usually do not work. Treating lupus is a long term treatment sometimes lasting years if the patient continues to have symptoms.
