I had a systemic parasitic infection of dwarf pork tapeworm, hookworms and roundworms. I was treated with 7 rounds of Vermox 3 days on four days off, the albendezole two weeks on one month off four times and then prazi two weeks on one month off twice. I also had a compounding pharmacist make a mixture to inhale - I had several months of inhaling three times a week this mixture plus a peroxide mixture rotating both. In my treatment I also used Wormwood , Black-Walnut , and most of the other holistic type treatments during the off days of the drugs. I changed my diet , I did not work, I spent much of the time sick but committed to the process. In my opinion the prazi was the best as it is a broad spectrum medication. It is also very hard on you so be prepared to suffer. I was closely monitored by my doctor during the 11 month period and it has been a year since I finished. Hope this helps
