HI, thanks for using healthcare magic Nutrolin is primarily given in diarrhoea. Your doctor may have a specific reason for prescribing it to your daughter, you may want to speak to him regarding the medication and its indication. In terms of your daughter s constipation , initial treatment would consist of increasing her fiber intake. This means ensuring that she uses at least 5 servings of fruits and vegetables daily along with adequate amount of fluids. If she remains constipated despite an adequate fiber intake then a pediatrician will rule out any other possible causes of constipation in children prior to the initiation of medication. I hope this helps
