I am wondering about this myself! From what Ive read, most people who use Fenbendazole for humans take it in the form of cycles instead of continuously taking it. Some people think that cycling helps to keep potential side effects in check out and that the body can adapt to the treatment. However, there has not been a long-term study in humans, so the experiences of the users listed in the wellness communities vary from one to anothersome of them say that they are getting the benefits and others are just careful because there is not enough research. Personally, for my own situation, I would like to discuss it with my doctor first. Has anyone here tried it out for a long time? I am willing to listen to your opinions!
