Dosage requirements of corticosteroids vary among individuals and the diseases being treated. The usual starting dose range is 5 mg to 60 mg daily depending on the disease being treated. Doses are adjusted based on patient response. In general, the lowest possible effective dose is used. Corticosteroids given in multiple doses throughout the day are more effective, but also more toxic than alternate-day therapy where twice the daily dose is administered every other morning. Prednisolone should be taken with food to reduce irritation of the stomach and intestines.
The following reporting rates of common adverse experiences are based upon 4 clinical trials in which 1196 patients (671 female and 525 male adults previously treated with as-needed bronchodilators and/or inhaled corticosteroids) were treated with QVAR (doses of 40, 80, 160, or 320 mcg twice daily) or CFC-BDP (doses of 42, 168, or 336 mcg twice daily) or placebo. Table 3 below includes all events reported by patients taking QVAR (whether considered drug related or not) that occurred at a rate over 3% for QVAR. In considering these data, difference in average duration of exposure and clinical trial design should be taken into account.
