Beth and BeyondtheRainbow, I once took as much as 300 mg of Lamictal, too. That ended up too much for me, but I never recall any pdoc calling it a very high dose. I once read that doses for bipolar disorder are usually lower than for epilepsy/seizures. I also know that people with epilepsy who take it often get Lamictal level blood tests, while for bipolar disorder that test is rarely if ever given. I have had such blood tests many times for carbamazepine (Tegretol) and of course Lithium. Even initially valproate sodium (Depakote). Though oxcarbazepine (Trileptal) is like a cousin of Tegretol, unlike Tegretol, such tests are uncommon for that med in bipolar, but do exist, like for Lamictal. I assume for a similar reason.
