I'm taking the iver once daily .I tried to take it twice per day and take the pyrantel at night with the second dose .Big mistake .For me it made my heart race a bit .But that tends to happen to me if I hit them too hard .I think it could be die off .
So I went back to one dose of iver and one dose of pyrantel at night and I have them down to nil. Scalp itch is almost gone .But then again I recently discovered that hydrocortisone cream helps with the scalp itch .
Im going to continue for a couple more weeks just to be sure .
Oh I am also using iver mixed with zinc oxide paste in my nether regions in case of auto re-infection and it seems to help immensely .
Good luck wormenstein
