Hi, I am Dr. Atul Kumar Nimawat.
IVIG is the standard treatment for CVID, but in patients with severe side effects, options like SCIG (subcutaneous immunoglobulin) may be better tolerated with fewer systemic reactions. Tablet-based alternatives are not effective replacements for immunoglobulin therapy. Pre-medications (antihistamines, steroids) and slower infusion rates can also help reduce IVIG side effects.
Next Steps
Please consult your immunologist to discuss switching to SCIG or modifying the current regimen.
