Thanks for posting your query.
I am Dr.Ratnakar Kini and I am pleased to assist you.
Not all cases of itching are due to pinworms
. There are other causes as well like hemorrhoids, contact dermatitis
, candidial infection, diabetes
, drinking coffee, cola beer etc.
So the treatment depends on the cause.
Regarding taking Reese's even in the absence of pinworm infestation, there is no need to worry as it is relatively safe.
I hope that answers your question.
