Hi, I had gone through your question and understand your concerns. Before taking any medicines, the right cause of his liver marler elevation should be established. GGt is sign of acute or chronic liver damage, it can be seen in gilberts syndrome or in bile duct disorders so you need to see child gastroenterologist first and do liver ultrasound and additional blood tests. Xymex syrup may not be efficient in most liver diseases. Only when diagnosis is established then treatment can be planned. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
