Hi, I been taking lamictal 75 mg daytime and 50 mg in evening. Considering that the level of lamicatal in blood was low, my Doctor suggested that I increase the dose by another 25mg, which means that now my daily dose is 75 mg twice a day. I am not sure if it's just a coincidence or a side effect because I have started experiencing heart burn and chest pain 48 hours after taking the medication. I have had to seek emergency help at hospital, they checked for heart attack (by a blood test) which was negative. Has anyone had a similar experience. Looking forward to replies and thanks in advance. Krish.
