Max. allowable dose of lamictal

Fri, 11/19/2010 - 11:36
In scanning several threads, I've noted that many people are on fairly high doses of lamictal (whether or not combined with other drugs). The highest dose I've read about so far in this forum is 450 mg. I am currently on 200 mg, and potentially will be increased to 250 - 300 mg. I've read that at doses of 300 mg. and higher that lamictal is being used as a med for bipolar (and perhaps depression, but I'm not sure). I definitely don't have either of those conditions, and probably none of you taking these higher doses does either. This leads me to the following questions: 1. What is the max allowable dose of lamictal? 2. Do higher levels of lamictal offer even greater seizure control? PLEASE correct me if I'm wrong, but I thought lamictal's effectiveness for controlling seizures "plateaued" once you reached 300 mg, and that's why at these higher doses it is considered a bipolar drug rather than an AED. Thanks in advance for any help!

They currently increased my lamictal to 750mg. 450mg night 300mg morning. By the end of the day I am so dizzy, nauseated, and have vertigo. I was fine on 150mg night and 200mg day. He wants me to go down to 300/300. I see you have an add on med. I am hoping he does this. Im certain the side affect are from too much Lamictal!
