month old baby with mastocytosis will chlorphenamine help?
No idea but I hope your baby recovers and will be completely healthy soon. You need to ask his doctor this. Here is a link about it though. http://familydoctor.org/online/famdocen/home/common/skin/disorders/441.html The good news according to this website is: “It’s usually mild in children, and they often outgrow it.” Good luck!!
