Hi, Thanks for posting in HCM. I have read your description and understand your concern. Pinworm is an intestinal infection caused by tiny parasitic worms. To treat pinworm infection, it is recommend an antiworm medication like Albendazole 200mg, which is given in one dose and repeated in 2 weeks. Although medicine takes care of the worm infection, the itching may continue for about a week. Regular hand washing and routine household cleaning, including frequent changing of underwear and bed linens will help prevent the spread of pinworm infection within the family and its reinfection. Hope the information provided would be helpful. All the best.
