Hear you on the pricing, Secretum!
I was on the name brand for awhile -- when Ex had decent job and insurance, so it was manageable, though still ridiculous. (Wanted to start on brand, so I'd know what to compare the effectiveness of generic to, you know?) After that, with a major move and much change and challenge, I was afraid to switch to generic, since the brand was working. Make sense? Oh, right, and no psych at the time, so if things went awry... So despite having no job and no insurance, I bit the bullet and forked it over (goodbye meager savings...)

Once things settled in a bit, and found a psych, switched to generic. Like you, Secretum, I'd done some reading, and found information of quite some interest, regarding not only between brand and generic in general, but between different manufacturers of generics. It's more of a problem with some drugs than others. (Then there are gov't standards (-20/+20 active ingredient) vs enforcement, issues of bioequivalent testing, independent studies and the quality of the various methodologies and test subjects thereof... yes, head-spinning.) These things matter of course, in terms of not accepting on blind faith, but what's most important by a mile, is what works for an individual.

But back to your question(!) Yes, I take one of the generic lamotrigines. It works for me.
Most important of course is what works for you! Keep us posted, ok?
