Re: Fenbendazole dosage

I took 1,000mg twice a day for 5 days, I think in a previous post I wrote 3 but it was longer more like 5, far apart like 10-12hrs. I did just fine. Fenben is poorly absorbed in humans and not good for much outside of the GI tract.....it was a while back so I dont have a link but I came across a study where some people were given 3-400mg? and blood draws never peaked to detectable levels.....fenben and pyrantel are both pretty much this way I think. The only benefit to taking a double dose of pyrantel is it will work for some forms of tapeworms. Tweet
