Yes, your son can be dewormed again now if a healthcare provider confirms a reinfection, as pinworm treatments typically require a two-dose schedule spaced exactly two weeks apart to kill newly hatched worms. Routine preventative deworming is generally done every 6 months,Other possibilities causing similar perianal itching include perianal eczema, fungal infections, or localized bacterial dermatitis. Recommended treatment options for pinworms include a planned schedule of over-the-counter Pyrantel pamoate, prescription Mebendazole, or Albendazole.
