View Full Version : Lamotrigine: Generics vs. Name Brand Lamictal

Since I was diagnosed with BPD five years ago, I've been taking 500 mg of lamotrigine every morning. This medication was only sold under the brand name Lamictal until earlier this year when a generic version became available. Since my copayment for generic meds is much lower than that for name-brand drugs, and since I've never had a problem with the performance of generic prescription meds, I decided to try it. If you're on Lamictal, be very careful if you decide to try generic lamotrigine, because it totally did not work for me.

Within a week or two, I could tell that something was wrong. I started feeling the way I did before my diagnosis...irritable, moody, etc. Not as bad as it was before the meds, but definitely not the way I had become used to feeling. Also, I developed an intermittent tremor in my left hand about the same time.

After a few weeks of this, I saw my psychiatrist and told her that it seemed like the lamotrigine was not working as well as it once had. I thought that I had developed a tolerance to it, which concerned me because as far as I am aware, this is the best med available for bipolar people who tend to be more depressed than manic. Also, 600 mg/day is the maximum recommended dose of this drug, and I've been at 500 mg for almost five years. I didn't tell her about the tremor because it didn't occur to me at the time that it could be connected to the medication.

The doc called me later that evening and told me that she had done some research about my experience with the generic drug. Although it hasn't been on the market very long, apparently other patients had reported the same problem. She said that sometimes the fillers used in generic meds reduces their effectivity in some people (lucky me!). She modified my prescription to disallow substitution with generics. I've been back on Lamictal for about two weeks, and I feel much, much better. The tremor in my hand is gone as well. I suppose that could be a coincidence, but I don't think so.

Just wanted to relate my experience and to warn people about the generic version of this drug. I'd encourage people to try the generic med carefully; if you feel that it's not working, tell your doc immediately and get back on Lamictal.

Cheers,
Kevin

I am told that with generics there is an "acceptable" margin of tolerance for the actually composition of the drug. Good that you noticed it.

I have a seizure disorder and tried switching off of Phenobarbital a couple of years ago and my doctor tried Lamictal on me. I didn't last too long, either the withdrawal from the pheno (which I suspect adds to my depression) or the Lamictal made me feel horrible.

The limictal did nothing for me.

Lamictal was originally approved for use as an anti-seizure med. Sorry that it didn't work for you - it's not a narcotic so it would at least have had that advantage over phenobarbital.

I take Escitalopram and have been on and off it over the past 6 years. Now on it for a while again. Think Im getting used to it as I sometimes struggle to keep my head above water. But I am constantly trying out the CBT which I learnt to do which sometimes helps but the mind keeps slipping back into its old ways. :(

Here is some info I found on Wiki on the drug -

Escitalopram (trade names Lexapro, Cipralex) is an antidepressant (http://en.wikipedia.org/wiki/Antidepressant) of the selective serotonin reuptake inhibitor (http://en.wikipedia.org/wiki/Selective_serotonin_reuptake_inhibitor) (SSRI) class. It is approved by the U.S. Food and Drug Administration (http://en.wikipedia.org/wiki/Food_and_Drug_Administration_(United_States)) (FDA) for the treatment of major depressive disorder (http://en.wikipedia.org/wiki/Major_depressive_disorder) and generalized anxiety disorder (http://en.wikipedia.org/wiki/Generalized_anxiety_disorder) in adults; other indications include social anxiety disorder (http://en.wikipedia.org/wiki/Social_anxiety_disorder), panic disorder (http://en.wikipedia.org/wiki/Panic_disorder) and obsessive-compulsive disorder (http://en.wikipedia.org/wiki/Obsessive-compulsive_disorder). Escitalopram is the S-stereoisomer (enantiomer (http://en.wikipedia.org/wiki/Enantiomer)) of the earlier Lundbeck drug citalopram (http://en.wikipedia.org/wiki/Citalopram) (Celexa), hence the name escitalopram. Escitalopram is noted for its high selectivity of serotonin reuptake inhibition and, as a result has fewer side effects not related to its serotonergic (http://en.wikipedia.org/wiki/Serotonergic) activity.<SUP class=reference id=cite_ref-pmid15014731_0-0>[1] (http://en.wikipedia.org/wiki/Escitalopram#cite_note-pmid15014731-0)</SUP> According to a meta-analysis of 12 new-generation antidepressants, escitalopram and sertraline (http://en.wikipedia.org/wiki/Sertraline) (Zoloft) are the best in terms of efficacy and acceptability in the acute-phase treatment of adults with major depression; however, sertraline may be a better choice because of the lower cost.

I always assumed generics were the same as the name brands. I didn't know there was room for error or differences between the medicines. I've never had a problem with generics and in fact, I take the generic Paxil for anxiety and it seems to work the same as the name brand.

I use generics when ever possible and have not had issues.
