Dear Soumya, Hi & Welcome.
What is the dosage of each tablet?
I appreciate your concern for your friend's niece.
There's nothing to worry about.
Accidental intake of one or two
Thyronorm tablets will not cause any complication as such.
Usually signs and symptoms related to heart like fast
heart rate,
palpitation, brain symptoms like irritability and hyper alert state may occur with the accidental consumption of Thyronorm in most of the healthy individuals including children.
Usually they don't need hospitalization but if any of these symptoms occur, a visit to ER is recommended for proper management and observation in the hospital.
Since stomach lavage (flush) has been done and she is being monitored in
ICU so, there's nothing to worry about her. She will be alright in due course of time.
Best regards.
