If that is the over the counter medicine for pinworms, it did nothing for me. I took half a bottle. Nothing. Garlic works great. Especially Natures Way Garlic Capsules. Take them orally and insert them in your anal sphincter.
Are you doing enemas to wash your colon out?
Have you flushed your liver?
I would boil some distilled water for an enema and add Epsom Salts to the water, break open some garlic capsules and add that to the enema water too. When you have emptied your bowels, insert another garlic capsule.
