How does LAMICTAL XR work?
LAMICTAL XR is an antiepileptic. It’s not exactly clear how this medication works to manage seizures and treat bipolar disorder.
For seizures, research suggests that lamotrigine (Lamictal) can block and prevent your brain from sending certain chemicals or signals that can overly excite your nerves. This helps lower bursts of activity in your brain, which can prevent seizures.
How do I take LAMICTAL XR?
LAMICTAL XR is typically started at a low dose, and the dose will be raised in the following weeks. The dose depends on what you’re taking lamotrigine (Lamictal) for, your age, and the other medications that you’re taking. Your dose might also differ if you have kidney or liver problems. The typical maintenance dose ranges from 200 mg to 600 mg once daily.
