Effectiveness
How Lamotrigine Affects PatientsLamotrigine helps stop seizures and helps manage moods by stabilizing brain cells and preventing the release of certain chemicals that can lead to seizures. While taking lamotrigine, the metabolite 2-N-methyl can be produced in small amounts. In high doses, this metabolite can cause abnormal heartbeat, widened blood vessels, and sometimes a complete blockage of the heart. People with liver disease may have higher levels of this metabolite and should talk to their doctor before taking lamotrigine.
How Lamotrigine works in the bodyLamotrigine works by blocking sodium from entering cells, which helps to regulate how much excitatory neurotransmitters, like glutamate, are released. This same mechanism also helps reduce anticonvulsant activity and manage bipolar disorder. Lamotrigine also binds to several different receptors, including serotonin, adenosine, alpha and beta adrenergic, dopamine, GABA, histamine, opioid, and mACh receptors. It also blocks the R-type calcium current, which may contribute to its anticonvulsant effects.

Lamotrigine Reviews: What are patients saying about Lamotrigine?
5Patient Review
2/19/2022 I'd been feeling low for a long time, and this treatment has really worked wonders for me. It's helped me feel happy and normal again. I highly recommend it to anyone who is struggling with similar issues.
4Patient Review
10/19/2021 I've been feeling more stable since starting this treatment, and my mood swings have become less frequent. I'm also beginning to feel like myself again - before depression and anxiety took over my life.I think this medication is working well with the antidepressant I'm taking (venlafaxine) to help manage my lows and make life feel more purposeful.
3Patient Review
11/9/2022 I began taking this medication a few weeks ago. I started with a low dose which I increased after two weeks. Since then, my depression has gotten worse and I've been having extreme suicidal thoughts.
3Patient Review
1/25/2022 I had high hopes for this medication, but unfortunately it didn't work well for me. I experienced a lot of energy at first, followed by insomnia. After that, I started feeling very drowsy during the day and decided to switch to taking it at night. That helped with the drowsiness somewhat, but then I started feeling depressed and confused. Overall, this just wasn't the right fit for me and I'll be discontinuing use.
2Patient Review
11/9/2022 The muscle spasms, tremors, and shakes were really bad. My teeth were clenched shut tight, too. I don't think I'll ever take this medication again. It made my schizophrenia worse, but I was taking it for depression.
2Patient Review
11/9/2022 Within two days of taking this medication, I started having uncontrollable muscle spasms and shivering, with my teeth clenched shut. It was a terrible experience. I will not be continuing to take it.
1Patient Review
7/13/2021 I was given this medication for bipolar disorder, even though I had never been diagnosed with it. The medicine caused me to have a sensitivity to other drugs, which then led to dystonia (twitching) and eventually painful muscle spasms in my neck. I had to be taken off the medication and put on something else. I'm still getting Botox injections as a result of the damage this drug did to me.
