What are the risks and recovery expectations?

Common risks include injection-site reactions (pain, redness, swelling), headache, and fatigue. Serious but rare risks include hypersensitivity reactions (e.g., anaphylaxis) and opportunistic infections like herpes zoster. Recovery is minimal—patients can resume normal activities immediately after each injection. Full benefit typically emerges after 3–4 months, with sustained reduction in exacerbations and oral corticosteroid use over the 12-month course.
