My wife 24 yrs old, ate odonil, almost chewed and she spitted out. but she had stomach wash, as she said that her throat and food pipe was itching. Its been almost 2 weeks before, this happened and treated her. But now she is telling that her stomach is paining, and she feels that her stomach is abnormal. Can you please advise that what will be the side effects?, i googled and saw the components in odonil, it says it has paradichlorobenzene. i am really worried.
