Help Parasite Medications. Animal dosages?

Hello,
I've had pinworms for two years. I just reinfected my son who hasn't had them in over a year. I've tried everything. I want to follow a strict protocol the next few months. However, the herbs are no longer working. My new doc won't prescribe me anything. I'm looking to try and buy mebandazole online at a pharmacy. Does anyone have good experience with actually receiving their product successfully? Who do you recommend? I'm also looking into Animal medications. Does anyone know of the guidelines to follow for body weight and what medications are available? I really appreciate the advice. I'm at my wit's end. I wish there was some type of medicine man in another country I could receive treatment from. I'd be on my way now. Tweet
