My son shivraj roy (2 & 1/2 years) old has been suffering from his stomach problem since birth. He can't digest milk since birth. Last one month he has been suffering from loose motion and also he has allergy problem. Our child specialist advised for stool test. But there was no infection in the stool test report. Our child specialist advised to give him rifagut 200 mg tablet (half tablet twice a day i.e. He has been taking one tablet per day) and gut pro syrup (5 ml twice a day i.e. 10 ml per day). Is these medicines safe for my child?
