My son just turned one. He has been on ranitidine for 11 months. I want to get him off the medication. After one week of reducing his meds as the dr. suggested he awoke in the middle of the night and screamed and cried for Over an HOUR. It was similar to what he was like before taking this medicine. Any advice on taking a child off the med. and/or any way to tell what side effects are caused from withdrawal. He seems fine during the day and happy
