Hi, I've never posted on one of these sites but here goes... Lamictal does indeed affect some vital nutrients. They are biotin, b12, b6, L-carnitine, folic acid, calcium, vitamin A, vitamin D, and vitamin K. My hair started falling out in clumps. I had my levels checked and I was VERY low on biotin, and L-carnitine. I was also low on zinc. I dropped my dosage from 150 to 100 to 75 to 50. With doctors approval. I started taking centrum silver and skin, hair, and nail vitamins and my hair stopped falling out and is starting to regrow. I am now back up to the 125 level and feeling better. I also started taking L-carnitine and that has helped as well although it had nothing to do with my hair loss. As to the other side effects...I have headaches, and neck stiffness, and sex headaches at the 100 plus level. And a buzzing/ vibrating in my right ear. For the migraines I take Advil. DO NOT TAKE TYLENOL WITH LAMICTAL. It lowers the level of lamictal in your system. I only take Excedrin when I must. I know this is long. I hope it helps. Even with all the side effects I still will take lamictal. It has made a huge difference for me. ( I also have occasional nausea and dizziness.) Hope this helps.
