I agree with Glax too. Last year I went to my regular Dr and told her that I have parasites and gave her my symptoms. She would only prescribe Menbendazole. She said because I have fatty liver, enlarged liver, and Hemochromatosis that this was the only drug she would agree to prescribe for me. It's the weakest one. She was afraid of harming my liver. She looked up different parasite meds side effects in one of her medical books and said there's no way she would give anything stronger than that because it would be extremely hard on the liver.
The Menbendazole did nothing for me. I had already tried different herbal dewormers that didn't work. But I'm not giving up. All I know is I only have one liver and I don't want it damaged any further with pharmaceuticals. I'm thinking of trying Barefoots dewormer next.
