My four-year-old son, whose seizures only occur at night, has been on Lamictal for almost 2 months now. We weened him onto this drug and off of Keppra during this time. He is currently on 50 mg of Lamictal in the morning and 50 mg before bed (and he weights 52 lbs). We have noticed (since increasing his bedtime dosage) that he is very shakey at night. It doesn't seem seizure related because the shakiness occurs at any point during the night when he is changing body position (for example, turning over to get comfortable). It is like a severe tremulousness and is very distubing. It also worsens as the night progresses. Any thoughts on what could cause this? At this point, our neurologist has suggested increasing the dosage of Lamictal, but I am leary. Thanks in advance for your thoughts!
