Is it safe to give noctura(Melatonin syrup) to 7.6 yr old as my son has a habit of taking too much stress of each other every small things and become extreme anxious. Today due to such stress he was feeling extreme dizziness,vomit twice and sweating so we took him to Dr so he prescribed this syrup to him sleep properly. kindly suggest. one more thing I have recently tested his TSH test so result came 5.74 ( As per lal path normal range is upto 6.30 ) but still it's on higher side.
