Anecdote, but I personally noticed variable effectiveness of epilepsy drugs between different generic manufacturers and the brand name. I was taking Teva brand for a while and it seemed to work fine. Soon I noticed that the drug wasn't working as well (i.e. had seizures) and I saw the brand I was taking changed (I forget what it was). Anyway I had to run around and find a pharmacy that had Teva brand again. I also learned you can ask your pharmacy what generic brand they carry, and you can also ask them to fill your prescription with a particular brand, but you have to give 1-2 days heads up. Ultimately, I ended up going on the brand name of the drug and it worked much more consistently. Often, if a generic drug isn't working well, doctors will write prescriptions that request the brand name so that insurance approves it. I think they all know that generics can be hit or miss for these types of drugs. Anyway, I don't take generics anymore. Now, almost every time I go to the pharmacy they ask me "You know how expensive this is, right?"... Yep. My insurance is billed for almost $5k every time I go, and I pay $180/mo. Generics would cost me $20/month or so. It must suck for people who can't afford it, or who have crapp(ier) insurance, or who don't even know about the variance between manufacturers.
