Reese's Pinworm Medicine - how long does this medicine take to work?

Pinworms are a parasite, while ringworms are considered a fungus as far as I know. I don't know anything that is cured by "pinworm medicine" - certainly not pinworms which are generally systemic throughout the entire body, easily passing through the skin barrier, the venous system, as well as the internal organs, and can easily be seen by the thousands within ten seconds when coaxed to the skin surface with a warm moist cloth, especially after administering of opioids, especially the lips, chin, and the areas between the breast and underarms where the skin is most easily able for the parasites to cross, due to it's suppleness.

Im just a mother very concerned... ive got a2yr old that has pin worms and ive cleaned and gave medicine .are u telling me there is no cure to rid of them period... Pin_x is whats helped not all the way throufh the 2nd cycle yet to say if shes cured. Im realy worried!

Till the fourth of never. I've also found that I've had to school both my Dr and Nurse on pinworms, but to be fair one doesn't know until experiencing this awful affliction there is yet no cure I know of on this planet.
