Management of Drug-Induced Leukocytoclastic Vasculitis

Initial Treatment and Steroid Protocol

The European League Against Rheumatism recommends beginning with high-dose glucocorticoid therapy at 1 mg/kg/day (maximum 60 mg/day) for drug-induced leukocytoclastic vasculitis 1
This initial high dose should be maintained for approximately one month, according to the European League Against Rheumatism 1
After the first month, the dose should be tapered gradually, with a goal to reduce to 15-20 mg/day within 2-3 months, as suggested by the European League Against Rheumatism 2
Further tapering to 5 mg/day should be done after continued improvement, as recommended by the European League Against Rheumatism 2
Complete withdrawal of steroids should be attempted if possible, though some patients may not tolerate complete discontinuation due to disease recurrence, according to the European League Against Rheumatism 1

For severe cases with organ involvement, higher initial doses (up to 1 mg/kg/day) and longer treatment duration (beyond 3 months) may be necessary, as suggested by the European League Against Rheumatism 1 and 2
Addition of other immunosuppressive agents should be considered if the patient is steroid-refractory, according to the European League Against Rheumatism 3
Bone protection therapy should be considered for all patients on prolonged steroid treatment, as recommended by the European League Against Rheumatism 1

Tapering steroids too quickly may lead to disease flare, as warned by the European League Against Rheumatism 2
Prolonged steroid exposure without consideration of steroid-sparing agents in refractory cases should be avoided, according to the European League Against Rheumatism 3
