Thank you for the information, I appreciate it. I've been trying to read as much about all of this as I can. That might be doing more harm than good because there is SO much conflicting information out there. From dosage information to the side effects of taking these medications. I read that somebody said your hair will fall out taking albendazole and it contains parabens. My hair has been falling out already (a symptom of my illness), and I don't think I could take it if all my hair fell out. What do you think of the fenben for fish? I've read that doesn't contain parabens.
