Potential Dosing Changes from July 1

Immunoglobulin adjusted body weight dosing

Your safety and effective treatment remain our highest priority. From 1 July 2026, you may notice a change to your immunoglobulin (Ig) dose. For most patients, any change is expected to be small. Your doctor can also keep your current dose if there is a clear medical reason.

For most adults, Ig doses will now be worked out using your adjusted body weight instead of your actual body weight. This is called adjusted body weight dosing. This means your dose will be based on your height and body build, not just your total weight.
