I have only tried Vermox and Prazi for short doses and lots of the natural herbs, tinctures, etc.
I am picking up the Albenza at the pharmacy in about a half an hour so I have not started it yet.
I have to mention again, that perhaps you don't have pinworms? I am just saying this as a possibility.
I don't know much about pinworms but from what I have read, they are pretty obvious to see with tape.
May I suggest that you might have another issue going on? There are several other things that cause anal itching/movment.
For example, it could be a different parasite, or candida strands or maybe something else.
I wish I could help you with some feedback. The only thing I can think of is applying a little coconut oil with a TINY drop of Oil of Oregano to the area. Be VERY careful with the Oil of Oregano as it's super strong and can burn the skin. That really helps with itching in that area.
