How much longer will pinworms persist if I am taking medication?

OTC or Prescription. If it wasn't for the itch & the difficulty these kids have trying to sleep, we wouldn't need to treat this at all. Short term help using a cold wash to remove the irritating oil the eggs are laid in & soothing creams can help baby rest.The otc med &/or the chew able vermox tablet will take a few days to work through the system & eliminated the pw's.
