What brand of fenbendazole ? is it for horses ? Nothing kills the eggs so what are you targeting ? I use horse meds which is 10 percent or 100 mg/g of fenbendazole my tube is 25 grams . I weigh a little under 100 kg and use 5grams of 10 percent product twice a day or 1000 mg per day . 100 kg of body weight x 10 mg per kg = 1000 mg per day . The first time I used fenbendazole was a 2 week double dose , then 5 day double doses every two weeks for 6 months . The 10 mg per kg is the double dose so I really did 5 mg per kg twice a day hence the double dose . If you are confused and not sure the tube should say how many mg per gram , and how many grams in tube . You weigh 70 kg x 10 mg per kg = 700 mg a proper 1day dose , or 350 mg twice a day . My tube lasts 2.5 days for my body weight. Hope this helps ,happy hunting and wish you well
