Barb, my insurance company recently switched me from TEVA to Zydus lamotrigine (I get my meds through the mail, and this is what they sent me the last time), and I found that I was not tolerating it nearly as well. I was switched by my pharmacy to the Teva generic from brand Lamictal and it seemed to work about the same. I did get a bum batch of lamotragine from my mail order.The new version they sent me was manufactured by Zydus Cadila, they are a pharma company in India. I still refer to the lamotrigine as lamictal.old habit for this old gal. I am currently transferring to a different medicare plan and have to start all over again finding new doctors which is stressful in itself, for I live in a rural area and doctors are hard to find. Dextroamphetamine Saccharate, Amphetamine Aspartate, Dextroamphetamine Sulfate and Amphetamine Sulfate tablet My M.D. switched me from lithium to lamotrigine in 2003 for bipolar disorder: Lamotrigine gave me my life back–no longer zombie-like. While on the Teva chewable (25 mg, 2x day), life was absolutely perfect so long as I never forgot to take it as prescribed. Lamotrigine I've been on Lamotrigine for over a year for bipolar with wonderful results, however, recently my mail order company sent me a new generic made by Zydus Cadila, (I had been taking Lamotrigine made by Teva out of Israel). Lamotrigine is an inexpensive drug used to control seizures in adults and children with epilepsy and Lennox-Gastaut syndrome. This drug is slightly more popular than comparable drugs. To clarify it was the Zydus form of the Generic that Gave me all of the issues and side effects I was experiencing. I started on Lamictal, then was given the generic Teva and finally in March my insurance switched me to Zydus. I'm in the same boat. Have been on 400mg a day of the TEVA lamotrigine. I just tried Taro and I don't think it's going to work. I have the feeling I would get in my body when I forgot to take my medicine. Lamotrigine Oral tablet drug summary.
