I was having some stomach ache mostly like gastritis. So, My physician has prescribed sucralfate and oxetacaine suspension twice a day 10ml with water half and hour  before food. From yesterday I have started taking this medicine, I had this medicine once before lunch at afternoon and once before dinner at night. Even tiday also before lunch I had this medicine. But from yesterday only and even today also I noticed after having this medicine I feel nausea and felt little bit dizziness today. Is it effecting me badly? And what time difference between should I follow to have doses of this medicine? Does this medicine reacting badly for me?
