Hi Chirpy,
Glad to hear your latest round went well.
In theory, more frequent and smaller doses would be preferable. The idea is that when you get a dose, you have a certain amount of IG floating around in your system. That gradually diminishes over days and weeks until it is not enough to counteract the CIDP, and then you get another dose. So there is a constant cycle of high IG, gradually going to low IG, and back to high IG.
If you get frequent, small treatments, this is evened out somewhat. The highs aren't as high, and the lows aren't as low.
Having said that, I personally chose larger, but less frequent, doses. It makes life so much easier to plan. My case is a little worse than yours, because I have to go in for three days when I get a round of IVIG. That pretty much shoots a week, and there isn't much else you can plan to do. And, as you say, I feel pretty drained after each day's treatment, so even though the infusion only takes a morning, the rest of the day is just about worthless. My doctor talked about coming in for only two days, but doing it more frequently. But I prevailed on him to stick to three days, but less frequently.
In any case, you have to decide what works for you, and minimizes your symptoms.
By the way, the nurses tell me that the reason I feel so tired on the day of a treatment is the fact that they give me a shot of Benadryl to minimize bad reactions. But, it lasts the entire day, and I am not sure one shot of Benadryl would do that. I have talked to one other woman who gets the CIDP on a similar schedule to me, and she tells me that she has the same response. So, I am wondering if you get the Benadryl? If so, maybe that is the reason. I am thinking of asking to have it without the Benadryl some time, so that maybe the rest of the day won't be such a loss.
