Re-infection with pinworms is highly common five months after the previous deworming course.
The standard dose of Zentel 400mg for a 9-year-old child is a single oral tablet.
According to clinical guidelines, you must repeat the same 400 mg dose exactly two weeks later.
To stop the cycle of reinfection, it is crucial to treat all household members at the same time.
Practice strict hand hygiene, trim nails short, and wash bedding in hot water frequently.
