You r covered by oxfendazole , fenbendazole metabolizes to oxfendazole in liver so no need for both , only do 1 bendazole at a time in same month , I had severe kidney pain from strongyloides and if u look up kidney transplants and strongyloides u will find countless articles where kidney recipient received strongyloides from donor. Donors were symptom free and healthy , so articles prove my point that strongyloides likes kidneys , they loved mine
