Excuse another barge here too. I just have a rather soft spot in my heart for fellow PUPPP sufferers!
From what I have read, PUPPPs only hits 1 in 1000 first time pregnancies during the last trimester (not to say there aren't unfortunate exceptions) so feel lucky, right?
I did the same thing of trying the oatmeal baths until my tub drain was getting clogged. I had a little success with Grandpa's Pine Tar soap but smelled like a campfire. Seriously, what the PP said about getting something stronger is so true. I had GD, so my diet was spot on- great prenatals, lots of omega 3's, naturally occuring nutrients, but none of that helped. I decided to start with the medical intervention a step at a time- got the rx strength cortizone cream which helped in short spurts, then took Benedryl, then started alternating with claritin (sitll doing the cream) and finally they had me do an oral steroid. It was the only relief! I'm sure there are other risks, but the serious ones didn't weigh heavy enough (IMO) to not take them. The biggest risk to me would really only happen if I were taking them long term and that would be a thinning of the skin. My OB said I would have to be taking them for about6 months solid for there to be any risk and the only good thing about PUPPP is that it goes away after delivery. The risk to baby is that it makes them grow, again, if this were longer term than a few weeks, it could be serious, but with the short time I had left, it wouldn't have time to take such an effect.
What Magen talked about is probably the "oral steroid dose pack". It's 6 days of pills with 6 taken the first day, 5 the next, then 4 until you only take one. All the times to take it are printed on it too. I did that, it did me well for about 6 weeks then I started in again, but only took 1 pill a day for a few days then delivered
So, yeah, even though the itching was managed, my skin still was all splotchy until about an hour after delivery then it was FINE! I did have a bit of itching on the tops of my feet for another month, but the cortizone cream or just good shea butter managed that.
I would have rather have had morning sickness than PUPPP!!!
