Tapering glucocorticoids and risk of flare in rheumatoid arthritis on biological disease-modifying antirheumatic drugs (bDMARDs).

We found that tapering to doses of >2.5 mg/day was generally effective in terms of risk of flare. Flare risk was higher when glucocorticoids were tapered to doses ≤2.5 mg/day. Our study might help design new tapering strategies in patients with RA on biological disease-modifying antirheumatic drugs.
