frequence and dosage for maintence IVIG

I have an appointment with my doctor on Monday to discuss what happens next. 🙂 I would like to thank you all again for your inputs. Now I have to figure out what dosage of IVIG and the frequency. It seems that 4 -6 [a month to a month and a half] weeks is the norm for maintenance. The maintenance dosage appears to be ,5 gm per Kilogram.
That would mean that someone my size [6’6” – 300 pounds], would require a dosage of 68 grams. The 4 to 6 week translates to 1.33 to 2 half lives. So the initial dosage of .5 gm/Kgm would be reduced to .188 to .125 gm/Kgm. I have been told that I should wait 3 month [90 days or 4.29 half lives]. That would reduce my dosage to .058 gm/Kgm. That low a dosage rate would appear to be totally ineffective.:(

If this is correct, I think I have a good argument to increase the frequency of the maintenance dosages. All I have to do is convince the doctor and then take on the military health care system. 😎

If anyone can see a mistake, please let me know. Again, thanks
