Perhaps you could offer us all a better explanation? Did Mylan forget to put any lamotrigine into their tablets?

You did, and there could be a hundred and one reasons why you felt bad at that time, one of which is due to the change in medication.

That is realistic.

I should never have started posting here again. People do not get well on this board, it just perpetuates illness. Everyone looking for the ultimate combo which does not exist.

Abstract
Objective: To evaluate whether generic substitution was associated with any difference in medical resource utilization for 5 widely used antiepileptic drugs (AEDs) in the United States.
Methods: Health insurance claims from PharMetrics Database, representing over 90 health plans between January 2000 and October 2007, were analyzed. Adult patients with epilepsy, continuously treated with carbamazepine, gabapentin, phenytoin, primidone, or zonisamide, were selected. An open-cohort design was used to classify patients into mutually exclusive periods of brand vs generic use of AEDs. Pharmacy and medical utilization were compared between the 2 periods with multivariate regression analyses. Results were stratified into epilepsy-related medical services, and stable (≤2 outpatient visits per year and no emergency room visit) vs unstable epilepsy. Time-to-event analyses were also performed for all services and epilepsy-related endpoints.
Results: A total of 18,125 patients were observed in the stable group and 15,500 patients in the unstable group. After adjustment of covariates, periods of generic AED treatment were associated with increased use of all prescription drugs (incidence rate ratio [IRR] [95% confidence interval (CI)] = 1.13 [1.131.14]) and higher epilepsy-related medical utilization rates (hospitalizations: IRR [95% CI] = 1.24 [1.191.30]; outpatient visits: IRR [95% CI] = 1.14 [1.131.16]; lengths of hospital stays: IRR [95% CI] = 1.29 [1.271.32]). Generic-use periods were associated with increased utilization rates in stable and unstable patients and with 20% increased risk of injury, compared to periods with brand use of AEDs.
Conclusions: Generic antiepileptic drug use was associated with significantly greater medical utilization and risk of epilepsy-related medical events, compared to brand use. This relationship was observed even in patients characterized as stable.
AED = antiepileptic drug; CI = confidence interval; ER = emergency room; HR = hazard ratio; ICD = International Classification of Diseases; IRR = incidence rate ratio.

I often think way too much is made of the brand vs generic issue, before generics are released they have to show bioequivelence, that is, not only contain the same amount of drug as the original, but show serum levers etc that are virtualy the same. 30 years ago they didnt, and problems werent uncommon, but there have been a lot of changes since then.

> I often think way too much is made of the brand vs generic issue
It only takes one bad drug to become an issue if you are the one taking it.
> before generics are released they have to show bioequivelence
No. In the US, there is a 20% range of difference which a generic drug is allowed to deviate from the original product with respect to absorption. There is nothing "equivalent" about a 20% difference.
> that is, not only contain the same amount of drug as the original, but show serum levers etc that are virtualy the same.
For some drugs and for some people "virtually" is not good enough.
I don't know why this is a big issue either.

I take two generic drugs, by the way. I am sure that the majority of generic products are clinically as effective as the original branded product.
