Dr gave me Vermox that is a drug that kills hookworms, pinworms, threadworms. It inhibits the parasite from absorbing sugars. It appears to be really basic. Only 2 tablets that you chew. Chew 1 of the tablets and then in 2 weeks chew another just to make sure they are gone. It is poorly absorbed by the intestine. It looks like a pretty basic treatment but it has been around for years and is quite efficient. Anybody tried it?? They have a great website.
