NO. It did NOT work well. This drug (Levimisol) caused our infestation to move to the skin where it has stayed now - forever. It is/was much more treatable in the GI tract but in the skin/lymph, not so. Now that we are beyond all of this and in our last stages of treatment that worked (Sharkman), we will move later this year to maintenance/preventive doses only. The low dose thing did NOT work; it does not affect the parasites and it DOES increase risks of immunity. Sharkman's protocol DID work and HAS worked to reduce our parasites to few, few few. There will always be encysted eggs which can & will hatch at some point, but because we are taking the correct meds regularly (Moxi for adults/some larva & Fenbendazole - all stages & encysted) they did not breed and make more. Our nightmare is basically over - 3+ years!
