I treated my 2 month old with albendazol on friday evening, but today which is sunday afternoon i am still seeing live pinworms in her stool. normal?

Probably: In most cases a repeat dose I week later does the trick. But your two month old is a bit young for pinworms, which required detailed assessment as to the sources of his infestation on what I assume a purely milk diet. On the other hand, make sure everyone else Round his gets treated simultaneously for him not to catch/give infection to/from others to keep the vicious cycle going.

Rare to see: pinworms in a 2 month old are you sure that they are worms if your doctor approves, a dose can repeated in 2 weeks contact your doctor
