My 19 year old son was diagnosis bipolar three years ago, and was put on Lamictal. He did very well on the medication, but quit taking it once he became an "adult." I finally convinced him to give it another six month trial, so he went to our family doctor yesterday to get started back on it. Family doctor started him on 100 mg twice daily. When he was on it before, we were told you had to start low and increase slowly (he started on 25 mg then). I called family doctor's office today, and was told by nurse that the dosage wasn't a mistake; that's how he's supposed to take it. Has anyone heard of starting this medication at such a high dose? My son has had allergic reactions to drugs before (penicillin), so I'm really reluctant to start him on this dose (though he really needs to be on something for all our sakes). I'm considering getting a pill splitter so he can start at a lower dose.
