Ann, we are taking Ivermectin weekly. Could Fenbendazole be used as a prophylactic against CV-19? Fenbendazole is also a parasite medication as ivermectin. However, it is being used to treat cancer: See Joe Tippens “My Cancer Story”. 220 milligrams for 3 days per week then take 4 days off. I’ve been on this regimen since March 2019 with no side affects. Bloodwork and PSA are great. It would be interesting what your doctor guests gave to say.
