~~HUGS~~ I would want my baby girl free of these nasty critters as soon as possible also. I only had to fight off pinworms at that young age with my daughter.
I would continue the paragone as the instructions state. Your doctor may suggest this as the method and not prescribe anything else.
From what I have read both drugs work the same on parasites. The parasites actually die from the drugs paralizing/stunning it. You need to be drinking a lot of water to move them out of the body and make sure you are not constipated.
Try typing in each drug in a search engine and see what you can find out, I didn't find out much.....heyjude
